2. Wiring: includes the power wiring and control wiring; Recheck the connection
according to our corresponding wire diagrams. Especially, please remember our communication
wire is polar; it means you must connect the communication wire correspondingly to the
terminal block.
3. Additional charge of refrigerant: Recheck the calculation formula and recalculate the
total recharge volume according to our supplied formula.
4. Open the stop-valve of gas and liquid pipe with Allen key; Check leakage of stop-valve
with soap water.
5. Test insulation; Turn on all of the indoor units and set the temperature in 17degree
with high speed in cooling mode first, after the system operated, test following system operation
parameters, including indoor units and outdoor units parameters.
Indoor unit’s parameter:
1. Air-inlet and air-outlet temperature of indoor units: Generally, the temperature
difference between them should be 10 degree according to and depended on the outdoor
ambient temperature, we think it is normal.
2. Fan speed of air-outlet of indoor units: Generally, for the duct type indoor units, the
fan speed of air-outlet should be 3m/s roughly.
3. Noise level: for the indoor units should be 40dB roughly.
Outdoor unit’s parameter:
Ambient temperature; Air-outlet of units; Air-outlet of units; Discharge temperature of
compressor; voltage; current; discharge pressure; air-inlet pressure; air-inlet pipe temperature
and compressor current. After tested all of the cooling parameters, transfer the cooling mode to
heating mode, then repeat the above process.
