Trial operation
• Before trial operation:
Before being electried, 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
electried for 6 hours, the compressor will not work.
Conrm the compressor bottom getting hot.
Except for the condition that there is only one master unit connected (no slave unit), under the other conditions, open
fully the outdoor operating valves (gas side, liquid side). If operating the unit without opening the valves, compressor
failure will occur.
Conrm all indoor units being electried. If not, water leakage will occur.
Measure the system pressure with pressure gauge, at the same time, operate the unit.
• Trial operation
In trial operation, refer to the information of performance section. When the unit can not start up at the room
temperature, make trial operation for outdoor.
Trial operation and the performance
Move and scrap the air conditioning
• When moving, to disassemble and re-install the air conditioning, please contact your dealer for technical support.
• In the composition material of air conditioning, the content of lead, mercury, hexavalent chromium, polybrominated
biphenyls and polybrominated diphenyl ethers are not more than 0.1% (mass fraction) and cadmium is not more than
0.01% (mass fraction).
• Please recycle the refrigerant before scrapping, moving, setting and repairing the air conditioning; for the air conditioning
scrapping, should be dealt with by the qualied enterprises.
