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 1M * . 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.
Confirm 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.
Confirm all indoor units being electrified. 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.
