Installation procedure B. Leakage test 1. The outdoor unit has been executed the leakage test in the factory. The pipe should be executed leakage test individually and forbidden to test after connecting with stop valve. 2. Refer to the below figure to charge the nitrogen into the unit to take a test. Never use the chlorin, oxygen, flammable gas in the leakage test.

Installation procedure D. Additional refrigerant charging Charge the additional refrigerant as liquid state with the gauge. If the additional refrigerant can not be charged totally when the outdoor stops, charge it at the trial mode. If the unit runs for a long period in the state of lack of refrigerant, compressor will occur failure. ( the charging must be finished within 30 minutes especially when the unit is running, meanwhile charging the refrigerant).

Trial operation and the performance 5-minute delay function • If starting up the unit after being powered off, the compressor will run about 5 minutes later against being damaged. Cooling/heating operation • Indoor units can be controlled individually, but cannot run in cool and heat mode at the same time. If the cool mode and the heat mode are existing simultaneously, the unit set latter will be standby, and the unit set earlier will run normally.
Trial operation and the performance Trial operation • Before trial operation: Before being electrified, measure the resistor between power terminal block (live wire and neutral wire) and the earthed point with a multimeter, and check if it is over 1MΩ. If not, the unit can not operate. To protect compressor, electrify the outdoor unit for at least 12 hours before the unit runs.If the crankcase heater is not electrified for 6 hours, the compressor will not work.
