Failure and analysis

The breaker trips at once when it

is set to "ON".

Measure insulation resistance to ground to see
if there is any leakage.

Trip of breaker or blow
of fuse

The breaker trips in few minutes
when it is set to "ON"

Check power supply circuit.

Check if the plug is properly plugged in and
make the loose contact firm.

Change controller fuse

Check remote controller

Change batteries

Change controller

Adjust setting temp.

Improper setting of temperature

Wire loose or wrong connection

In cool, heat mode,the

incorrect, change the transformer

Air conditioner can not start up

The air conditioner

does not react after

it is powered ( after

the plug is inserted,

the buzzer does

not sound and the

remote startup has

no response)

The remote controller

does not receive

signals (after it is

powered, the buzzer

will sound, unless it

has malfunction)

The circuit or the part of the air conditioner has

malfunction. They heat and break the insulation

and lead to short circuit or creepage. Measure

the insulation resistance or eliminate the malfunc-

tion one by one. If the breaker itself has

malfunction, then replace the breaker.

The transformer connection is loose or has bad
contact or the transformer has malfunction

First, press the manual switch button AUTO,
if there is no response,check based on the
above methods. If it runs normally after
pressing the button,check again whether the
installation position and the connection wire
of the reception head is correct. If it is
correct,then replace the receiver or the re-

mote controller.

heck the voltage. If it is lower than 10£¥ of the rated voltage, check the

cause, improve the power supply condition and add the stabilized voltage
power supply.

creepage of parallel capacitor of relay loop,

relay is broken etc.)

Note: When replacing the controller, make sure insert the wire jumper into the new controller, otherwise, the running indicator off 3s,
