6.4.2 Recommended maintenance and inspection
As the use of the unit for many years will eventually lead to a dust
layer, the performance of the unit will degenerate to a certain extent.
As professional skills are needed to dismantle and clean the unit, and
for the optimal maintenance effects of this unit, please contact your
agent for more details.
When you request the agent for assistance, please remember to state:
▪ Complete model name of the air conditioner.
▪ Date of installation.
▪ Details on the fault symptoms or errors, and any defects.
Warning
▪ Do not attempt to modify, dismantle, remove, reinstall or repair
this unit, as the improper dismantling or installation may result
in electric shock or fire. Please contact the agent.
▪ If the refrigerant accidentally leaks, make sure that there is no
fire around the unit. The refrigerant itself is completely safe,
non-toxic and non-flammable, but it will produce toxic gases
when it accidentally leaks and comes in contact with flammable
substances generated by existing heaters, and burning devices
in the room. You must get a qualified maintenance personnel to
verify that the point of leakage has been repaired or rectified
before you restore the operations of the unit.
6.4.3 Shorter maintenance and replacement cycle
In the following situations, the "maintenance cycle" and "replacement
cycle" may be shortened.
The unit is used in the following situations:
▪ Temperature and humidity fluctuations are outside the normal
ranges.
▪ Large power fluctuations (voltage, frequency, waveform distortion
etc.) (must not use the unit if the power fluctuations exceed the
allowed range).
▪ Frequent collisions and vibrations.
▪ The air may contain dust, salt, harmful gas or oil such as sulphite
and hydrogen sulphide.
▪ Frequent on and off of unit or operating time is too long (in places
where the air conditioning is on for 24 hours a day).
7 Troubleshooting
The warranty does not cover the damage caused by dismantling or
cleaning of the internal components by unauthorized agents.
Warning
When any unusual situations arises (burning odour, etc.), stop
the unit immediately and turn off the power.
As a result of a certain situation, the unit has caused damage, an
electric shock, or a fire. Please contact the agent.
The system maintenance must be carried out by a qualified maintenance
personnel:
Error
If a safety device, such as a fuse, circuit
breaker or a leakage circuit breaker is
triggered frequently or the ON/OFF
switch is not working properly.
The operating switch is not functioning
normally.
If the unit number is displayed on the
user interface, and the operating
indicator is flickering, and an error
code is shown on the screen as well.
Other than the above-mentioned situations, and where the fault is
not obvious, if the system continues to malfunction, carry out the
following steps to investigate.
Error
If the system does not
run at all.
If the system works
fine in the fan-only
operating mode but
stop running once it
enters the heating or
cooling operation
modes.
The system is running
but there is insufficient
cooling or heating.

Measures
Turn off the main power
switch.
Turn off the power supply.
Notify the installation
personnel and report the
error code.
Measures
▪ Check if there is a power failure. Wait for
the power supply to be restored. If a
power failure occurs when the unit is still
running, the system will restart
automatically once the power is restored.
▪ Check if the fuse is broken or if the circuit
breaker is working. If necessary, replace
the fuse or reset the circuit breaker.
▪ Check if the air inlets or outlets of the
outdoor or indoor units are blocked by
any obstacles. Remove the obstacles,
and maintain good ventilation in the room.
▪ Check if the air inlets or outlets of the
outdoor or indoor units are blocked by
any obstacles.
▪ Remove the obstacles, and maintain
good ventilation in the room.
▪ Check if the filter is blocked (please refer
to the "Maintenance" section in the
manual of the indoor unit).
▪ Check the temperature settings.
▪ Check the fan speed settings on the
user interface.
▪ Check if the doors and windows are
open. Close the doors and windows to
shut out wind from the external
environment.
▪ Check if there are too many people in
the room when the cooling mode is in
operation. Check if the heat source of
the room is too high.
▪ Check if there is direct sunlight into the
room. Use curtains or blinds.
▪ Check that the angle of air flow is
appropriate.
