POSSIBLE CAUSE

SOLUTION

Water leakage

Rubber plug at the rear plate of the machine
is out of place.

Water tube inside the machine is not in the
place or broken.
Water tube is of bad connection or broken.

Put back the rubber plug.

Check and reinstall or replace the water
tube inside the machine.
Check or replace the water tube.

Weak cooling Dusty filter

Dusty condenser.

Air vent is blocked.
The room temperature is too high.

Too many windows or doors are open.
Insufficient refrigerant or the refrigerant leaks
out..
HEAT PUMP is broken.

Clean the filter.
Use a high pressure air spray to clean
the dust. *Do not touch the condenser
directly, it is very hot now.
Remove the blockade.
It’s out of the working range of the
machine.
Close the windows/doors.
Please check:
Is the current/power consumption
decreasing?
Is the suction pressure of the machine
too low?
Is the temperature of the discharging
tube too high?
Is the suction tube frozen in ambient
temperature?

7. Replace the heat pump.

Machine does not
work at all.

Bad connection of the mains and plug.
P.C. Board fused.
P.C. Board or transformer breaks down.
Bad connection of the wires.

Re-plug the power cord.

work, only the fan to
circulate the air.

Voltage/Frequency is too low.
Overload protector of compressor breaks
down.
Compressor capacitor breaks down.
Compressor breaks down.
P.C. board breaks down.
Room temperature is too low.

Check it by a voltmeter.
Check and replace.

Auto-drainage system
doesn’t work.

Wires problem.
Pump motor breaks down.
Bad installation of the water pump.
Micro switch breaks down.

Check and replace.
Check and replace.
Re-install.
Check and replace.

Suction pressure is too
low while the suction
temperature is too high.

Blocked capillary
Blocked evaporator.
Blocked refrigerant filter.
Insufficient refrigerant or the refrigerant
has been leaked.

Replace the capillary.
Use high pressure N2 to clean the
evaporator or replace it.
Replace the refrigerant filter.
Release the remained refrigerant,
vacuum the unit (at least over
755mmHg). Recharge the unit. For
correct refrigerant amount, please refer
to the rating label at the back of the
unit. The deviation should be within 3g.
