Test Run & Fault Code
Before Test Run
• Before switching it on, test the supply terminal tier (L, N terminals) and grounding points with 500V mega ohm meter
and check if the resistance is above 1MO. It can't be operated if it is below 1MO. 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.
Checkup of Installation
check if the mains voltage is matching
check if there is air leakage at the piping joints
check if the connections of mains power and indoor & outdoor units are correct
check if the serial numbers of terminals are matching
check if the installation place meets the requirement
check if there is too much noise
check if the connecting line is fastened
check if the connectors for tubing are heat insulated
check if the water is drained to the outside
check if the indoor units are positioned
Ways of Test Run
Ask the installation personnel to make a test run. Take the testing procedures according to the manual and check if
the temperature regulator works properly.
If machine fails to start due to the room temperature, then follow these instructions. Remember this function is not
applicable for the remote controller.
Set the wired controller to refrigerating/heating mode, press "ON/OFF" button for 5 seconds to enter into the
compulsive refrigerating/heating mode. Repress "ON/OFF" button to quit the compulsive running and stop the
operation of the air conditioner.
