Page 47: Trial Operation And The Performance
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. -
Page 48: Move And Scrap The Air Conditioning
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. - Page 52 Qingdao Haier Air Conditioner Electric Co.,Ltd.
