• Before doing repair work, please read the " SAFETY PRECAUTIONS" carefully and fully understand them. • The precautionary items here are divided into " W arning" and " Caution" items.
W arning If refrigerant gas blows off during the work, do not touch the refrigerant gas as it may cause frostbite. If refrigerant gas leaks during the work, ventilate the room. If refrigerant gas catches fire, harmful gas may be generated. Do not mix any gas other than the specified refrigerant gas in the refrigerating cycle.

Emergency operation Emergency operation is available when the remote controller malfunctions, has been lost, or otherwise cannot be used. • The set temperature is 4°F(2°C) below the detected room temperature in the case of cooling operation.
HIGH POWER NIGHT SETBACK Lamp colors Ti mer backup This function acts to raise the power but keeps the AC system in the same operating mode. This function is set with the HIGH POWER button on the remote controller . (It can be set regardless of the temperature and fan speed settings.
The noise reducing control is the function used for silent operation of the air conditioner by means of setting the dip switch on the outdoor unit P.C.
The maximum current value is changed to 14A (for C3082) or 17A (for C3682) to prevent power breaker tripping. (It is set to 24A when the unit is delivered from the factory.) <Maximum Current Value Change Procedure> (1) Remove the inspection panel.
Compressor discharge temperature control Freeze prevention During COOL or D RY operation, freezing is detected and operation is stopped when the temperature of the indoor heat exchanger matches the conditions below . 1. Freeze-prevention operation is engaged when the temperature of the indoor heat exchanger is below 41°F(5°C).
8. TROUBLESHOOTING 8-1. Precautions before Performing Inspection or Repair NOTE After checking the self-diagnostics monitor , turn the power OFF before starting inspection or repair . High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter).
Since the indications cover various units, the corresponding parts listed below may not be present in some models. (1) OPERATION lamp (2) TIMER lamp (3) LED CLEAN lamp OPERATION TIMER LED CLEAN ON/OFF INDOOR UNIT (1) Self-diagnostics Lamps .... OFF ..
(2) If the self-diagnostics function fails to operate Check the indoor unit. Is the fuse blown? Replace the controller. Replace the circuit board or the fuse.
8-3. Checking the Indoor and Outdoor Units (1) Checking the indoor unit (2) Checking the outdoor unit Using the TEST/T-RUN terminals Control No. Check items (unit operation) T -RUN :T est run (compressor and fan motor turn ON). TEST/MV : Compresses time to 1/60th (accelerates operation by 60 times faster than normal).
(3) Serial Communication Error Identification Procedure Refer to "Method of Self-Diagnostics" for the self-diagnostics procedure. (3-1) Alarm Code : E05 < Before the Operation > If the.
What is the latest self-diagnosis result ? Alarm Code : E07/P04/P05/ P20/P27 Alarm Code : E07/P04/P05/ P20/P27 Defect in the outdoor unit P. C. board. Alarm Code : E05 Defect or connection error in the inter-unit cable Defect in the indoor unit P .C. board ( Continued from the previous page A.
(3-2) Alarm Code : E07/P04/P05/P20/P27 T roubleshooting Serial Communication 1. T urn off the power and wait until the power lamp (LED) of the outdoor unit controller is turned OFF . 2. Disconnect the cable from the terminal 3 on the indoor unit terminal strip.
[T rouble symptom 3] Motor rotates for some time (several seconds), but then quickly stops, when the indoor unit operates. (There is trouble in the system that provides feedback of motor rotation speed from the motor to the indoor unit controller .
8-4-2. Outdoor 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 T est Run mode described on Installation Instructions of indoor unit.
8-5. Noise Malfunction and Electromagnetic Interference An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external noise, and is likely to cause electromagnetic interference with nearby wireless devices.

10. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN SERVICING UNIT 10-1. Characteristics of New Refrigerant R410A 10-1-1. What is New Refrigerant R410A? R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture.
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.
10-3. Tools Specifically for R410A For servicing, use the following tools for R410A Gauge manifold Charging hose Gas leak detector Refrigerant cylinder Charging cylinder Refrigerant recovery unit Vacu.
10-5. In Case of Compressor Malfunction CAUTION 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 "10-3. Tools Specifically for R410A.
Valve Single valve Charge liquid refrigerant with cylinder in up-side-down position. Single valve (with siphon tube) Charge with cylinder in normal position. Liquid Valve Liquid Charging cylinder Open Refrigerant cylinder Liquid NO! CAUTION Never charge a large amount of liquid refrigerant at once to the unit.
Length of tubing Evacuation time Less than 33 ft. (10 m) More than 10 minutes More than 33 ft. (10 m) More than 15 minutes 10-6. In Case Refrigerant is Leaking CAUTION Never attempt to charge additional refrigerant when refrigerant has been leaking from the unit.
10-7. Charging Additional Refrigerant 10-7-1. When Tubes are Extended 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.

23 5. Refrigerant T ubing 5-1. Use of the Flaring Method Many of the con ventional split system air conditioners emplo y the flaring method to connect refr igerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts.
24 5-4. Connecting T ubing between Indoor and Outdoor Units a) Tightly connect the indoor side refrigerant tubing exten- ded from the wall with the outdoor side tubing.
25 6. Air Purging Air and moisture remaining in the refrigerant system hav e undesirab le effects as indicated belo w . Theref ore, they m ust be purged completely .
26 (5) With the vacuum pump still running, close the “Lo” knob of the manif old valv e. Then stop the vacuum pump . (6) With the hex wrench, turn the valv e stem on the nar- row tube service valv e counter-clockwise b y 90 degrees (1/4 turn) for 10 seconds , and then tur n the stem clockwise to close it again.
27 How to T est Run the Air Conditioner After tur ning on the pow er of the air conditioner , use the remote controller and f ollow the steps below to conduct the test run. (1) Set the remote controller in T est Run mode. (Fig. 59a) a) Press and hold the QUIET button and the 1HR.
28 ■ Pump Down Pump down means collecting all refrigerant gas in the system back into the outdoor unit without losing an y of the gas. Pump down is used when the unit is to be mov ed or bef ore ser vicing the refrigerant circuit. Pump Down Pr ocedure Be sure to carry out pump down with the unit in cooling mode.
a) T emporar y connection: Screw in 3 – 5 turns b y hand. (Fig. 60c) b) T o fasten the flare nuts , apply specified torque as T able 9 and Fig. 60d. Fig. 60c Fig. 60d CAUTION T orque wrench Be sure to tighten the flare nut using the prescribed torque.
30 8. Address Switch 8-1. Address Setting of the Remote Control Unit The address can be set in order to pre vent interf erence between remote controllers when 2 indoor units are installed near each other . The address is nor mally set to “A. ” T o set a different address , it is necessar y to change the address on the second remote controller .
