Improper setting of temperature<br />
Adjust the set temperature<br />
Whether cooling (heating) load<br />
is proper<br />
Check the estimated load of cooling (heating)<br />
Leakage or shortage of refrigerant<br />
Vacuumize after leakage detection<br />
<strong>and</strong> leakage repair. Charge refrigerant<br />
according to specification.<br />
Malfunction of<br />
refrigerant flow<br />
Leakage occurs between high <strong>and</strong><br />
low pressure inside compressor<br />
Malfunction of four-way valve<br />
Replace the compressor<br />
Replace the four-way valve<br />
Partial blockage of capillary<br />
Replace the capillary<br />
Poor cooling<br />
(heating) effect<br />
Poor thermal insulation of connecting<br />
pipe of indoor <strong>and</strong> outdoor unit<br />
Blockage of cooling system<br />
Use the method of observing condensation<br />
on the evaporator <strong>and</strong> pressure value of<br />
high pressure manometer to see whether<br />
the system is blocked <strong>and</strong> carry out<br />
corresponding h<strong>and</strong>ling on the system<br />
Ensure that both thick pipe <strong>and</strong> thin pipe are insulated<br />
well. The exposed part of the connector <strong>and</strong> copper pipe<br />
must be insulated as well.<br />
Heat exchanger of outdoor unit<br />
is blocked<br />
Air filters are blocked<br />
Clean the dust accumulated on the<br />
surface of the heat exchanger<br />
Clean the filter<br />
Air circulation<br />
is insufficient<br />
Fan speed is set too slow<br />
Fan speed turns low<br />
Improper installation location<br />
for outdoor unit<br />
Set the fan speed to high or medium<br />
speed<br />
Damage of<br />
capacitor<br />
damaged<br />
Damage of<br />
motor<br />
Replace<br />
capacitor<br />
Replace the motor<br />
Outdoor unit should be installed in a<br />
place with well ventilation<br />
the<br />
Outdoor temperature is too high<br />
Flashing or awning can be installed appropriately. If the<br />
max. cooling capacity cannot be satisfied, replacement of<br />
the air conditioner is recommended.<br />
Indoor sealability is inadequate; too many<br />
people go in <strong>and</strong> out frequently; there is<br />
heating unit in the room.<br />
Maintain a certain degree of indoor sealability. Try not to<br />
use appliance with high amount of heat.<br />
