Failure diagnosis at the moment of first installation
In case nothing is displayed on the remote controller (the current
set temperature does not display), check for any of the following
abnormalities before you can diagnose possible malfunction
codes.
Disconnection or wiring error (between power supply and
outdoor unit, between outdoor unit and indoor units, between
indoor unit and remote controller).
The fuse on the outdoor unit PCB may have run out.
If the remote controller shows " E3 ", " E4 " or " L8 " as an error code,
there is a possibility that either the stop valves are closed, or that
air inlet or air outlet are blocked.
If the error code " U2 " is displayed on the remote controller, check
for voltage imbalance.
If the error code "L4" is displayed on the remote controller, it is
possible that air inlet or air outlet are blocked.

AINTENANCE AND SERVICING
Service precautions
WARNING: ELECTRIC SHOCK
Caution when performing service to inverter equipment
DANGER
Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.
Make sure that the power supply is turned off before
performing the maintenance work. The heater of the
compressor may operate even in stop mode.
Please note that some sections of the electric component box
are extremely hot.
In order to prevent damage to the PCB, first eliminate static
electricity by touching a metal part (e.g. stop valve) with your
hand. Then pull out the connector.
After measuring the residual voltage, pull out the outdoor fan
connector.
Make sure you do not touch a conductive section.
The outdoor fan may rotate due to strong backblow wind,
causing the capacitor to charge. This may result in an electric
shock.
After maintenance, make sure the outdoor fan connector is
connected again. Otherwise, the unit may break down.
Play it safe!
Touch a metal part by hand (such as the stop valve) in
order to eliminate static electricity and to protect the PCB
before performing service.
Service mode operation
Refer to the service manual to carry out any service mode operation.
