Before switching it on, test the supply terminal tier (L, N terminals) and grounding points with
500V megaohm meter and check if the resistance is above 1M*. It can't be operated if it is below
1M*.
Connect it to the power supply of outdoor units to energize the heating belt of the compressor.
To protect the compressor at startup, power it on 12 hours prior to the operation.
Check if the arrangements of the drainpipe and connection line are correct.
The drainpipe shall be placed at the lower part while the connection line placed at the upper part.
Heat preservation measures should be taken such as winding the drainpipe esp. in the indoor
units with heating insulating materials.
The drain pipe should be made a slope type to avoid protruding at the upper part and concaving
at the lower part on the way.
