7-3. Diagram of Outdoor Unit Installation Never install only a single indoor unit. Be sure to connect indoor and outdoor units only in combinations that are listed in the catalog or in the combination table that was provided with the indoor unit.
7-4. Recommended Wire Length and Diameter Regulations on wiring diameter differ from locality to locality. For field wiring requirements, please refer to your local electrical codes. Carefully observe these regulations when carrying out the installation. Table 2 shows maximum wire lengths for control line and power line and fuse or circuit capacity.
8-1. Current Control 8- . Low Start Current The operating current may rise as a result of causes Operation starts at 10 Hz, and the start current is less than including increasing heating or cooling loads or the normal operating current. This prevents the flickering of decreases in power voltage.
9. TROUBLESHOOTING 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. 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.

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. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22. 10-1-2.
Page 36
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.
10-3. 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 Vacuum pump with anti-reverse flow (*1) Tools specifically for R410A (Solenoid valve-installed type, which prevents oil from flowing back into the unit when the power is off, is recommended.) Vacuum pump (*2) …...
10-5. In Case of Compressor Malfunction Should the compressor malfunction, be sure to make the switch to a replacement CAUTION compressor as quickly as possible. Use only the tools indicated exclusively for R410A. See “10-3. Tools Specifically for R410A.” 10-5-1. Procedure for replacing compressor (1) Recovering refrigerant Any remaining refrigerant inside the unit should not be released to the atmosphere, but recovered using the...

(5) Recharging Configuration and characteristics of cylinders Valve 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. When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation.
10-6. In Case Refrigerant is Leaking Never attempt to charge additional refrigerant when refrigerant has been leaking CAUTION 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 (1) Detect leaks points.
Page 41
(6) Recharging Configuration and characteristics of cylinders Valve 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. When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation.
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. Never charge additional refrigerant if refrigerant is leaking from the unit. Follow CAUTION instructions given in “10-6.
APPENDIX UNIT COMBINATION TABLES NOTE 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.
