IMPORTANT These air conditioners employ new refrigerant R410A. Pay special attention when servicing the unit. Wall mounted type CS-MKS7NKU CS-MKS9NKU CS-MKS12NKU CS-MKS18NKU CS-MKS24NKU < Applicabl.
• Before doing repair work, please read the " SAFETY PRECA UTIONS" 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 wor k, 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.

Control/conditions COOL The ON/OFF operation button on the remote controller is pressed. The room temperature has reached the desired temperature. The outdoor unit does not operate for 3 minutes even after the breaker is turned ON. This is in order to stabilize the return of oil to the compressor.
Control/conditions SENSOR DRY (1/f fluctuation fan) The ON/OFF operation button on the remote controller is pressed. The outdoor unit does not operate for 3 minutes even after the breaker is turned ON. This is in order to stabilize the return of oil to the compressor.
< Low Ambient Cooling Operation > When the mode is switched from cooling opration to low ambient cooling operation, the compressor is stopped for 150 seconds temporarily.

8. TROUBLESHOOTING (BEFORE CALLING FOR SERVICE) 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 outdoor-side electronic circuits.
8-2. Trouble Diagnosis by Error Monitor Lamps 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.
8-3-1. Checking the outdoor unit 8-3. Checking the Outdoor System Work procedure Apply 220 V AC between terminals L1 and L2 on the outdoor unit terminal plate. • Short-circuit the T-RUN terminal to the COM terminal of TEST/T-RUN terminals. • The LED (red) on the control board must illuminate.
8-4. Trouble Diagnosis of Each Part 8-4-1. Problems of Each Part and Inspection Points For details about the inspection points, refer to the Inspection Points for Each Part.
8-4-2. Inspection Points for Each Part (1) Outdoor control cir cuit board Refer to 8-3-1. Checking the outdoor unit. (2) Fuse Check it visually or the continuity with a tester.
No voltage on circuit board (6) Electric expansion v alve When replacing the electric expansion valve and coil, be sure to attach the connectors in the correct positions. Labels are applied to the valve body and coil, corresponding to the connector colors, to identify them.
(7) Branch tubing temperature sensor Check that the sensor is securely contained in the thermostat holder. (8) Breaker Check whether or not the breaker has been tripped. Check that the breakers and fuses used are of the specified capacity. Check that the breaker and its line are exclusive for A/C use.
8-5. Trouble Diagnosis of Fan Motor This outdoor DC f an motor contains an inter nal control PCB. Theref ore, it is not possible to measure the coil resistance, and the f ollowing procedure should be used to chec k the motor . P erform the trouble diagnosis by T est Run mode descr ibed on Installation Instr uctions of indoor unit.
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.
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.
9-3. 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 Vacuu.
9-5. 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 "9-3. 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 9-6. In Case Refrigerant is Leaking CAUTION Never attempt to charge additional refrigerant when refrigerant has been leaking from the unit.
9-7. Charging Additional Refrigerant 9-7-1. 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.
