Common Questions
8 totalWhat is the maximum operating temperature range for cooling?
The maximum indoor air intake temperature for cooling is 95 °F D.B., and the outdoor air intake temperature can reach up to 115 °F D.B.
How do I troubleshoot if my Outdoor control circuit board fails?
Before inspecting or repairing, allow at least 30 minutes for high-capacitance electrolytic capacitors to discharge. Ensure the Power Lamp (red) on the P.C.Board has turned off.
What should I do to insulate refrigerant tubing?
Both wide and narrow tubes of this air conditioner may become cold, so insulate them with proper insulation material. The thickness of the insulation should be a minimum of 8 mm.
How do I check if my outdoor unit is functioning correctly?
Apply 220 V AC between terminals L1 and L2 on the outdoor unit terminal plate, and verify the LED (red) illuminates. Short-circuit the T-RUN terminal to COM of TEST/T-RUN terminals; then compressor and fan motor should turn ON about 70 seconds after power is turned on.
How do I set the indoor room temperature?
Press the ON/OFF button on the remote controller to start initial operation. Depending on user settings and ambient conditions, it will enter AUTO operation or COOL mode.
How do I verify that outdoor unit error monitor lamps are functioning?
Remove the top plate of the outdoor unit cover of Electrical Component Box. Check that Power Lamp and Error Monitor Lamps (ERR0, ERR1, ERR2, ERR3) illuminate as expected on control board under test conditions.

WARNING
WARNING
Important! Please Read Before Starting
This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.
For safe installation and trouble-free operation, you must: Carefully read this instruction booklet before beginning. Follow each installation or repair step exactly as shown. Observe all local, state, and national electrical codes. Pay close attention to all warning and caution notices given in this manual.
If Necessary, Get Help These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions.
In Case of Improper Installation The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.
Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked. Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death. Ground the unit following local electrical codes. Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.
When Installing In a Ceiling or Wall Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support. In a Room Properly insulate any tubing run inside a room to prevent "sweating" that can cause dripping and water damage to walls and floors. In Moist or Uneven Locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration. In an Area with High Winds Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle. In a Snowy Area (for Heat Pump-type Systems) Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents. When Connecting Refrigerant Tubing
Use the flare method for connecting tubing. Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection. Check carefully for leaks before starting the test run.
When Servicing
Turn the power off at the main power box (mains) before opening the unit to check or repair electrical parts and wiring. Keep your fingers and clothing away from any moving parts. Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.
Others
Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas. Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.| |---|

############### Insulation of Refrigerant Tubing
####################### IMPORTANT
Because capillary tubing is used in the outdoor unit, both the wide and narrow tubes of this air conditioner become cold. To prevent heat loss and wet floors due to dripping of condensation, both tubes must be well insulated with a proper insulation material. The thickness of the insulation should be a min.5/16"(8 mm).

NOTE
The numerical values such as temperature, frequency, time and current in parentheses are an example of CM3172 and the values are different from the other models.
############# 7-2-1. Current Control
The operating current may rise as a result of causes including increasing cooling loads or decreases in power voltage. In these cases, the operating frequency is automatically reduced, or operation is stopped, in order to control the operating current so that it is (20 A) or less.
As a result:
• • •
Power breakers and fuses will not be tripped. Operation can continue during this period with somewhat reduced cooling capacity. Operation at normal capacity is restored when the cause of the current rise is eliminated.

##### 8. TROUBLESHOOTING
######## 8-1. Precautions before Performing Inspection or Repair
############# Both the indoor unit and outdoor unit include electronic control circuits. Be sure to pay attention to the following before inspecting or repairing the outdoorside electronic circuits.
High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge (charging voltage DC 311 V) even after the power is turned OFF, and some time is required for the charge to dissipate.
Be careful not to touch any electrified parts before the control circuit board Power Lamp (red) turns OFF. If the outdoor control circuit board is normal, approximately 180 seconds will be required for the charge to dissipate. However, allow at least 30 minutes for the charge to dissipate if it is thought there might be trouble with the outdoor control circuit board. For example, if the outdoor control circuit board fuse has blown, approximately 30 minutes will be required to discharge the high-capacity electrolytic capacitors.
######## 8-2. Trouble Diagnosis by Error Monitor Lamps
WARNING
To prevent electric shock, do not inspect or repair until the Power Lamp on the P.C.Board is turned off.
############# 8-2-1. Location of the Error Monitor Lamps
Remove the top plate of outdoor unit and the cover of Electrical Component Box. The Power Lamp and Error Monitor Lamps are located on the P.C.Board of Electrical Component Box. (Fig.1)

Start a COOL test run, and messure the temperatures of the A/C intake air and discharge air. Compare the values with the performance charts.
If the values are higher than the performance charts: Check for refrigerant shortage or blockage of the refrigerant circuit.
< Assessment of refrigerant shortage >
< Distinguishing between refrigerant shortage and refrigerant circuit blockage > If the pressure in the low-pressure section does not change when the circuit is charged 2 to 3 times with refrigerant gas (0.44 lbs each time), or if the change is small, then the problem may not be refrigerant shortage.
The problem may be a blockage of the refrigerant circuit.
############# 8-5. Trouble Diagnosis of Fan Motor
This outdoor DC fan motor contains an internal control PCB. Therefore, it is not possible to measure the coil resistance, and the following procedure should be used to check the motor. Perform the trouble diagnosis by Test Run mode described on Installation Instructions of indoor unit.
Important: (A) Turn OFF the power before connecting or disconnecting the motor connectors.
(B) When performing voltage measurement at the outdoor controller connector for (3) in the table below, the DC motor will trip and voltage output will stop approximately 10 seconds after operation is started. For this reason, to measure the voltage again, first turn OFF the outdoor unit power, then, measure the voltage in Test Run mode.
(Diagnostic results) All of the above measured values are normal. Fan motor trouble (Replace the motor.) Any one of the above measured values is not normal. Outdoor unit controller trouble
(Replace the controller .) (Reference) DC motor connector pin arrangement
|Measurement location|Normal value| |---|---| |(1) Vm-Gnd: Between pin 1 and pin 4|DC 230V or more| |(2) Vcc-Gnd: Between pin 5 and pin 4|DC 14V or more| |(3) Vsp-Gnd: Between pin 7 and pin 4|After fluctuating 4 times between DC 1.7 to 6.1V (1 sec. ON) and DC 0 V (1 sec. OFF), the DC motor trips.|
(Remedy for symptom 3 to 5) It is not possible to identify whether the trouble is outdoor unit controller trouble or motor trouble. Therefore, first replace the outdoor unit controller, then (if necessary) replace the DC motor.
##### 9. REFRIGERANT R410A:SPECIAL PRECAUTIONS WHEN SERVICING UNIT
######## 9-1. Characteristics of New Refrigerant R410A
############# 9-1-1. What is New Refrigerant R410A?
R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22.
############# 9-1-2. Components (mixing proportions)HFC32 (50%) / HFC125 (50%)9-1-3. Characteristics
Less toxic, more chemically stable refrigerant The composition of refrigerant R410A changes whether it is in a gaseous phase or liquid phase. Thus, when there is a refrigerant leak the basic performance of the air conditioner may be degraded because of a change in composition of the remaining refrigerant. Therefore, do not add new refrigerant.Instead, recover the remaining refrigerant with the refrigerant recovery unit. Then, after evacuation, totally recharge the specified amount of refrigerant with the new refrigerant at its normal mixed composition state (in liquid phase). When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or liquid phase, and the basic performance of the air conditioner will be degraded if it is charged while the refrigerant is in gaseous state. Thus, always charge the refrigerant while it is in liquid phase.
|CAUTION| |---|
Ether-type oil is used for compressor oil for R410A-type units, which is different from the mineral oil used for R22. Thus more attention to moisture prevention and faster replacement work compared with conventional models are required.
######## 9-2. Checklist before Servicing
Use a clutch-type flare tool for R410A or the conventional flare tool. Note that sizes of the resultant flares differ between these two tools. Where a conventional flare tool is used, make sure to observe A Specification (amount of extrusion) by using the flare spacer.
|Diameter of tube D|Specification A|Specification A| |---|---|---| |Diameter of tube D|Flare tool for R410A|Conventional flare tool (for R22)| |Dia.1/4" (6.35 mm)|0 to 0.0196" (0 to 0.5 mm)|0.0472" (1.2 mm)| |Dia.3/8" (9.52 mm)|0 to 0.0196" (0 to 0.5 mm)|0.0472" (1.2 mm)| |Dia.1/2" (12.7 mm)|0 to 0.0196" (0 to 0.5 mm)|0.0472" (1.2 mm)| |Dia.5/8" (15.88 mm)|0 to 0.0196" (0 to 0.5 mm)|0.0472" (1.2 mm)|

Flare tool for R410A
Conventional flare tool (R22)
Tubing precautions Refrigerant R410A is more easily affected by dust or moisture compared with R22, thus be sure to temporarily cover the ends of the tubing with caps or tape prior to installation. Never use 0.0276" (0.7 mm)-thick copper tubing or tubing which is less than 0.0315" (0.8 mm) in thickness, since air conditioners with R410A are subject to higher pressure than those using R22 and R407C. No addition of compressor oil for R410A No additional charge of compressor oil is permitted. No use of refrigerant other than R410A Never use a refrigerant other than R410A. If refrigerant R410A is exposed to fire
Through welding, etc., toxic gas may be released when R410A refrigerant is exposed to fire. Therefore, be sure to provide ample ventilation during installation work.
Caution in case of R410A leak Check for possible leak points with the special leak detector for R410A. If a leak occurs inside the room, immediately provide thorough ventilation.
######## 9-3. Tools Specifically for R410A
For servicing, use the following tools for R410A
|Tool Distinction|Tool Name| |---|---| |Tools specifically for R410A|Gauge manifold Charging hose Gas leak detector Refrigerant cylinder Charging cylinder Refrigerant recovery unit Vacuum pump with anti-reverse flow (*1) (Solenoid valve-installed type, which prevents oil from flowing back into the unit when the power is off, is recommended.) Vacuum pump (*2)...can be used if the following adapter is attached. Vacuum pump adapter (reverse-flow prevention adapter) (*3). (Solenoid valve-installed adapter attached to a conventional vacuum pump.) Electronic scale for charging refrigerant Flare tool| |Tools which can be commonly used for R22, R407C, and R410A|Bender Torque wrench Cutter, reamer Welding tool, nitrogen gas cylinder|
The above tools specifically for R410A must not be used for R22 and R407C. Doing so will cause malfunction of the unit. For the above vacuum pump (*1, *2) and vacuum pump adapter (*3), those for R22-type units can be used for R410A-type. However, they must be used exclusively for R410A and never alternately with R22 and R407C.
|CAUTION| |---|
To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, shape and external diameter of the service port screw has been altered.
######## 9-4. Tubing Installation Procedures
################### When the tubes are connected, always apply HAB oil on the flare portions to improve the sealing of tubing.
The following is the HAB oil generally used: Esso: ZERICE S32
############################ NOTE
For details on tubing installation procedures, refer to the installation manuals attached to the indoor unit and outdoor unit.
######## 9-5. In Case of Compressor Malfunction
Should the compressor malfunction, be sure to make the switch to a replacement compressor as quickly as possible. Use only the tools indicated exclusively for R410A. See "9-3. Tools Specifically for R410A."
|CAUTION| |---|
############# 9-5-1. Procedure for Replacing Compressor
####################### (1) Recovering refrigerant
Any remaining refrigerant inside the unit should not be released to the atmosphere, but recovered using the refrigerant recovery unit for R410A. Do not reuse the recovered refrigerant, since it will contain impurities.
####################### (2) Replacing Compressor
Soon after removing seals of both discharge and suction tubes of the new compressor, replace it quickly.
####################### (3) Checking for sealing
Use nitrogen gas for the pressurized gas, and never use a refrigerant other than R410A. Also do not use oxygen or any flammable gas.
####################### (4) Evacuation
Use a solenoid valve-installed vacuum pumpso that even if power is cut off in the middle of evacuation of air due to a power interruption, the valve will prevent the pump oil from flowing back. The equipment may be damaged if moisture remains in the tubing, thus carry out the evacuation thoroughly. When using a vacuum pump with exhaust air volume more than 0.883 cu.ft./min. and ultimate vacuum pressure rate of 50 micron Hg.
OK
OK
Standard time for evacuation
|Length of tubing|Less than 33 ft. (10 m)|More than 33 ft. (10 m)| |---|---|---| |Evacuation time|More than 10 minutes|More than 15 minutes|
Be sure to charge the specified amount of refrigerant in liquid stateusing the service port of the wide tube service valve. The proper amount is listed on the unit's nameplate.
When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation.
Never charge a large amount of liquid refrigerant at once to the unit. This may cause damage to the compressor.
|CAUTION| |---|
When charging with a refrigerant cylinder, use an electronic scale for charging refrigerant. In this case, if the volume of refrigerant in the cylinder becomes less than 20% of the fully-charged amount, the composition of the refrigerant starts to change. Thus, do not use the refrigerant if the amount in the charging cylinder is less than 20%.
Also, charge the minimum necessary amount to the charging cylinder before using it to charge the air conditioning unit.
Example: In case of charging refrigerant to a unit requiring 1.68 lb. (0.76 Kg) using a capacity of a 22 lb. (10 Kg) cylinder, the minimum necessary amount for the cylinder is:
1.68 + 22 0.20 = 6.08 lb. (0.76 + 10 0.20 = 2.76 Kg)
################### For the remaining refrigerant, refer to the instructions of the refrigerant manufacturer.
If using a charging cylinder, transfer the specified amount of liquid refrigerant from the refrigerant cylinder to the charging cylinder. Prepare an evacuated charging cylinder beforehand.
To prevent the composition of R410A from changing, never bleed the refrigerant gas into the atmosphere while transferring the refrigerant. (Fig. 3)
|CAUTION| |---|
Do not use the refrigerant if the amount in the charging cylinder is less than 20%.

######## 9-6. In Case Refrigerant is Leaking
|CAUTION| |---|
Never attempt to charge additional refrigerant when refrigerant has been leaking from the unit. Follow the procedure described below to locate points of leaks and carry out repairs, then recharge the refrigerant.
Use the detector for R410A to locate refrigerant leak points.
Never release the gas to the atmosphere; recover residual refrigerant using the refrigerant recovery unit for R410A, instead. Do not reuse the recovered refrigerant because its composition will have been altered.
Confirm again that no residual refrigerant exists in the unit before starting welding. Weld securely using flux and wax for R410A.
Prevent oxide film from forming inside the tubes utilizing substitution with nitrogen (N2) in the refrigerant circuit of the unit. Leave ends of tubes open during welding.
Use nitrogen gas for the pressurized gas, and never use a refrigerant other than R410A. Also do not use oxygen or any flammable gas.
Use a solenoid valve-installed vacuum pumpso that even if power is cut off in the middle of evacuation of air due to a power interruption, the valve will prevent the pump oil from flowing back. The equipment may be damaged if moisture remains in the tubing, thus carry out the evacuation thoroughly. When using a vacuum pump with exhaust air volume more than 0.883 cu.ft./min. and ultimate vacuum pressure rate of 50 micron Hg.

######## 9-7. Charging Additional Refrigerant
Observe the proper amount of refrigerant as stated in this service manual or the installation manual that came with the indoor unit. Charge additional refrigerant in liquid state only.
9-8. Retro-Fitting Existing Systems
####################### Never charge additional refrigerant if refrigerant is leaking from the unit. Follow instructions given in "9-6. In Case Refrigerant is Leaking" and completely carry out repairs. Only then should you recharge the refrigerant.
|CAUTION| |---|
Never use new refrigerant R410A for existing units which use R22.This will cause the air conditioner to operate improperly and may result in a hazardous condition.
9-8-2. Use of Existing Tubing If replacing an older unit that used refrigerant R22 with a R410A unit, do not use its existing tubing.Instead, completely new tubing must be used.

############# SPECIAL PRECAUTIONS
WARNING
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.
################# When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.
When Installing… …In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support.
########################## …In a Room
Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.
…In Moist or Uneven Locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration. …In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle. …In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.

It is recommended to use baffle plates for models CLM1972, CLM2472 and CLM3172. The baffle plates are not normally required for the other models. When the outdoor unit is installed in a position exposed to strong wind (such as seasonal winds with low air temperature in winter), baffle plates must be installed on the outdoor unit. (Fig. 5f) This unit is designed so that the fan of the outdoor unit runs at low speed when the air conditioner is operated at low outdoor air temperatures. When the outdoor unit is exposed to strong wind, the system pressure drops because of the freeze protector. Install a pair of windbaffle plates at the front and back of the outdoor unit if it will be subject to strong wind during the winter. (Figs. 5f, 5g, 5h, 5i, and 5j)

####################### 3-6. Insulation of Refrigerant Tubing
IMPORTANT
To prevent heat loss and wet floors due to dripping of condensation, both tubes must be well insulated with a proper insulation material. The thickness of the insulation should be a minimum 5/16" (8 mm). (Fig. 17)
####################### 3-7. Taping the Tubes
After a tube has been insulated, never try to bend it into a narrow curve, as this may cause the tube to break or crack.
|CAUTION| |---|
NOTE
Do not wind the armoring tape too tightly, since this will decrease the heat insulation effect. Also, be sure the condensation drain hose splits away from the bundle and drips clear of the unit and the tubing.
####################### 3-8. Finishing the Installation
After finishing insulating and taping over the tubing, use sealing putty to seal off the hole in the wall to prevent rain and draft from entering. (Fig. 19)

|CAUTION| |---|
If a CFC gas detector is used, use a special detector for HFC refrigerant (such as R410 and R134a).
############# Pump Down
|In order to protect the earth’s environment, be sure to perform pump-down to recover refrigerant gas without releasing it into the atmosphere.| |---|
When relocating or disposing of the A/C, request this service from the dealer where the unit was purchased, or from an appropriate agent. Perform pump-down as described below.
What is pump-down? Pump-down refers to recovering the refrigerant gas from the refrigerant cycle at the outdoor unit. This work must be performed during cooling operation. The refrigerant gas cannot be recovered during heating operation. During winter, or if the temperature sensor prevents cooling operation, perform “forced cooling operation.”
####################### Pump-down procedure
If pump-down is not possible If the A/C cannot be operated because of a malfunction or other cause, use a refrigerant recovery device to recover the refrigerant.

It is therefore possible to connect 4 units with respective capacities of 7500 + 7500 + 7500 + 17500. However, since this combination is not found in the 4-room operation column of Table 2, operating all these units concurrently may result in trouble. At a time like this, shut down at least one of the 4 indoor units to match one of the combinations

############ Conditions:
Example: When 4 indoor units are connected If the following holds true
|at 230V| |---|
Rated cooling capacity of indoor units: K1, K2, ... (BTU/h) Then:
It is therefore possible to connect 4 units with respective capacities of 7500 + 7500 + 11900 + 24200.
|4-Room Outdoor Unit Combination Table| |---|
In this case, all the indoor units installed must not be operated concurrently under any circumstances. Otherwise, the air conditioner may not run properly and trouble may occur.
|Be sure to operate the air conditioning system only when 2 or more indoor units have been installed. If operated with only a single unit installed, the returning fluid to the compressor may cause a malfunction.

Rated cooling capacity of CM3172 outdoor unit: C=30600 (BTU/h)
If the following holds true
Rated cooling capacity of indoor units: K1, K2, ... (BTU/h) Then:
It is therefore possible to connect 4 units with respective capacities of 7500 + 7500 + 11900 + 24200. However, since this combination is not found in the 4-room operation column of Table 2, operating all these units concurrently may result in trouble. At a time like this, shut down at least one of the 4 indoor units to match one of the combinations
