The setting temprature is
improper
Whether the cooling load is proper
or not
The refrigerant is leaking or insufficient
There's leakage high and low
pressure in the compressor
The flow malfunction
of regrigerant
Part of the capillary is blocked
The cooling system is blocked
Heat insulation for the connection pipes
of the indoor unit and the outdoor unit is not well
The fan speed is set too low
Air circulation is
insuffiecent
The fan speed
becomes low
The installation position of the
outdoor unit is not appropriate.
The outdoor temp. is too high
The air tightness in room is not good.
People come in and go out frequently.There
are heating devices in the room.
Adjust the setting temperature
Check the forecast cooling load
Make sure that the heat insulation for the heavy tube and
microtube is good. The joint and the exposed part of the copper
pipe should also be heat insulated. .
The outdoor heat exchanger
is blocked
Air filter is blocked
Capacitor is damaged
(with capacitor) or controller
is damaged (with PG motor)
Motor is damaged
We can install the rainproof plate or the sunproof plate.
If the max. cooling is still not insufficient, you are suggested
to replace the A/C.
Keep the air tightness well. Try not to use the electric
appliances with a large quantity of heat.

Check and fill out the leakage, then
vacuumize it. Complement the
refrigerant is required
Replace the compressor
Replace the capillary
Check whether the system is blocked by
observing the condensation of evaporator and
the pressure value of the highpressure
manometer and then take measures to deal
with the system.
Clean the dust on the surface of heat
exchanger
Clean the filter
Set the fan speed to medium or high
Replace the capacitor
or the controller
Replace the motor
Good ventilation must be provided for the
installation of the outdoor unit.
