COMMISSIONING Test Run • Check the power supply between outdoor unit and switch board. 1. 220 V power supply (L / N) 2. 380 V power supply – make sure the phase sequence are correct, L 1(R) L 2(S) L 3(T) • Outdoor unit powered ON 6 hours in advance to preheat the crankcase heater. • If main power is turned OFF for a long time, the system cannot run immediately after power resume. (Need to wait for 2. 5 hours)

COMMISSIONING Test Run Continue… • Indoor unit checking: 1. Check the power supply wiring and signal wiring in each indoor unit. 2. If the signal wire and power wire are cross-connected, all PCB will burn. 3. The signal wires must be in different colour for different terminal in order to avoid misconnection of polarity. 4. Check the address setting of the indoor unit: – Make sure the address settings are correct. – Each indoor unit should have different address. • Outdoor unit checking: 1. Check the no. of indoor unit settings are correct. 2. Make sure the capacity settings are correct. 3. Make sure the Master and Slave unit setting are correct (if applicable).
