When Transporting Important! Please Read Before Starting 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. 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.

Defrost Detection and Release (1) Non-stop defrosting Defrosting sequence Heating operation 4-way valve ON Defrost detection occurs in either of the following cases: • The temperature of the heat exchanger remains at or below the L1 line for 35 minutes after the start of HEAT operation.
PAGE 50
7-2-2. Current Control The operating current may rise as a result of causes including increasing heating or 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 heating or cooling capacity.
PAGE 51
7-2-3. Low Start Current Operation starts at (8 Hz), and the start current is less than the normal operating current. This prevents the flickering of fluorescent lights or television screens that occurs when ordinary A/C units start. 7-2-4. Compressor Temperature Control To protect the compressor coil from overheating, the operating frequency is controlled based on the compressor discharge temperature. Compressor discharge temperature (°C) Trip (110) 5Hz every 30 sec. reduction (106) 2Hz every 30 sec.

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.

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) Heat Exchanger Rear side P.C.Board of Electrical Component Box.

8-4-2. Inspection Points for Each Part (1) Outdoor control circuit board Refer to 8-3-1. Checking the outdoor unit. NOTE Do not remove or insert the outdoor control circuit board connector when power is being supplied to it. (The controller will be damaged.) (2) Fuse Check it visually or the continuity with a tester. (3) Compressor Check for an open circuit in the compressor coil winding.
PAGE 57
(8) Branch tubing temperature sensor Check that the sensor is securely contained in the thermostat holder. (9) 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. (10) Refrigerant gas pressure 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.
PAGE 58
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.

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.
PAGE 60
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 0.7mm-thick copper tubing or tubing which is less than 0.8mm 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.
PAGE 61
9-3. Tools Specifically for R410A For servicing, use the following tools for R410A Tool Distinction Tool Name Gauge manifold Charging hose Gas leak detector Refrigerant cylinder Charging cylinder Refrigerant recovery unit Tools specifically for R410A 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.
PAGE 62
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. for R410A." See "9-3. Tools Specifically 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.
PAGE 63
(5) Recharging Configuration and characteristics of cylinders Be sure to charge the specified amount of refrigerant in liquid state using the service port of the wide tube service valve. The proper amount is listed on the unit's nameplate. Valve When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation. Liquid CAUTION Never charge a large amount of liquid refrigerant at once to the unit. This may cause damage to the compressor.
PAGE 64
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. (1) Detecting Leaks Use the detector for R410A to locate refrigerant leak points.
PAGE 65
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. CAUTION 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. 9-8.
