Test Run & Fault Code - Airwell AWSI-DCV072-N11 Manuel D'installation

Test Run & Fault Code
Before Test Run
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 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 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
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 the room temperature, the following procedures can be taken
to do the compulsive running. The function is not provided for the type with remote control.
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.
Fault Remedies
When any fault appears, consult the fault code of line control or the flashing times for LED5 of computer
