Test Run & Fault Code
Before Test Run
Before switching it on, test the supply terminal tier (L, N terminals) and grounding points with a 500V megaohm meter
l
and check if the resistance is above 1MΩ. It can't be operated if it is below 1MΩ.
Connect it to the power supply of outdoor units to energize the heating belt of the compressor. To protect the compressor
l
at startup, power it on 12 hours before the operation.
Check if the arrangements of the drainpipe and connection line are correct.
The drainpipe is placed at the lower part, while the connection line is placed at the upper part. Heat preservation measures
are taken such as winding the drainpipe esp. in the indoor units with heating insulating materials.
The drain pipe is shaped in a slope type to avoid protruding at the upper part and concaving at the lower part on its way out.
Checkup of Installation
check if the mains voltage is matching
o
check if there is air leakage at the piping joints
o
check if the connections of mains power and the indoor & outdoor units are correct
o
check if the serial numbers of terminals are matching
o
check if the installation place meets the requirement
o
check if there is too much noise
o
check if the connecting line is fastened
o
check if the connectors for tubing are heat insulated
o
check if the water is drained towards the outside
o
check if the indoor units are positioned correctly
o
Ways of Test Run
Do 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. When the machine fails to start due to faulty room temperature, the following
measures can be taken to do the compulsive running. The function is not provided for the models with remote control.
To set the wired controller to refrigerating/heating mode, press the "ON/OFF" button for 5 seconds to enter into the com-
l
pulsive refrigerating/heating mode. Repress the "ON/OFF" button to quit the compulsive running and stop the operation
of the air conditioner.
