Caution  
After the confirmation of the above conditions, prepare the wiring as follows:  
1. Never fail to have an individual power circuit specifically for the air  
conditioner. As for the method of wiring, be guided by the circuit diagram  
posted on the inside of control cover.  
2. The screws which fasten the wiring in the casing of electrical fittings are  
liable to come loose from vibrations to which the unit is subjected during  
the course of transportation. Check them and make sure that they are all  
tightly fastened. (If they are loose, it could cause burn-out of the wires.)  
3. Specification of power source.  
4. Confirm that electrical capacity is sufficient.  
5. See to that the starting voltage is maintained at more than 90 percent of  
the rated voltage marked on the name plate.  
6. Confirm that the cable thickness is as specified in the power source  
specification.  
7. Always install an earth leakage circuit breaker in a wet or moist area.  
8. The following would be caused by voltage drop: vibration of a magnetic  
switch, which will damage the contact point, fuse breaking, disturbance of  
the normal function of the overload protector.  
9. The means for disconnection from a power supply shall be incorporated  
in the fixed wiring and have an air gap contact separation of at least 0.12  
inch in each active (phase) conductors.  
Air purging  
Air and moisture in the refrigeration system have undesirable effects as indicated  
below:  
1. Pressure in the system rises.  
2. Operating current rises.  
5. Water may lead to corrosion of  
parts in the refrigeration system.  
Therefore, the indoor unit and tubing  
between the indoor and outdoor unit  
must apply leakage test and be evacuated  
to remove any noncondensables and  
moisture from the system.  
3. Cooling or heating(only for  
models with heating function)  
efficiency drops.  
4. Moisture in the refrigerant circuit  
may freeze and block capillary  
tubing.

Electrical work and air purging 24  
Air purging with vacuum pump  
1. Check that each tube(both liquid and gas side tubes) between the indoor and  
outdoor units have been properly connected and all wiring for the test run has  
been completed. Remove the service valve caps from both the gas and the  
liquid side on the outdoor unit. Note that both the liquid and the gas side  
service valves on the outdoor unit are kept closed at this stage.  
2. When relocating the unit to another place, perform evacuation using vacuum  
pump.
