Page 3: Product Features
Product Features • The outdoor uint adopts "simultaneous control" type, all indoors should be heating or cooli.ng simultaneously. • To protect compressor,before startup,the unit should be electrified for 12 hours.If the unit is not used for a long time, please cut off the power to save energy, or the unit will consume the power. This manual describes the installation and installation of outdoor units. - Page 4 Safety • The maintenance cover plate of the indoor or outdoor machine is forbidden when the main circuit power supply is not cut off. • The leakage of refrigerant can cause the air to be thin and difficult to breathe. In case of refrigerant leakage, close the main valve, extinguish any flame and contact the local distributor immediately.

Page 26: Trial Operation And The Performance
Trial operation and the performance Confirm the type of outdoor machine and the number of inside machine • After installation, please confirm that the outdoor computer board BM1_1 is in the 0 state, and then to the unit power, observe the digital display. If the number of the indoor machine and the outdoor machine type, the power supply voltage is correct, then the BM1_1 dial to 1 of the state, if it is not correct, please check the dial machine communication code and models, do not force the BM1_1 dial to 1 of the state, it may cause failure of the system. - Page 27 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.
