4.Warning and Cautions

Warning and Cautions

WARNINGS:

Electrical Safety

GROUNDING:

WARNING:

Do not, under any circumstances, cut or remove the third (ground) prong from the
power cord.

Adapter Plug:

This room air conditioner must be grounded. Grounding reduces the risk of electric shock by
providing an escape wire for the electric current. The power cord has a grounding wire with a
grounding plug . Plug it into an outlet that is properly installed and grounded.

Improper use of the grounding plug can result in a risk of electric shock.
Call a qualified electrician if you don’t understand the grounding instructions or if you are not sure

if the air conditioner is properly grounded. If the wall outlet is not grounded, please contact an
electrician to have it replaced with a proper grounded outlet.

We strongly advise against using an adapter plug.

Abnormity Diagnose

7. Abnormity Diagnose

1. Sensor Diagnose:

2 seconds after the sensors open circuit or short circuit, the unit will turn off automatically and the LED will show

E0 until the sensors resume.

Firstly check whether Terminal CN2 on

the indoor mainboard contact well or

not?

YES

Pull the sensor out of the mainboard

1) Measure the value of resistance

between its two jumpers

2) Measure the temperature at the
room temperature sensing head.
Check the specifications of the sensor

to deside whether the sensor is
damaged or not?

NO

NO

YES

Pull out the terminals on the indoor

mainboard and reinsert them.

Replace with new sensor.

The Indoor PCB is broken.

YES

Replace with new indoor PCB

Abnormity Diagnose

2. Keystroke circuit error diagnose:

When power on for the first time, the PCB will check the keystroke circuit, is the sampling value is defferent

with the theory value, the LED will show E1, which means failed keystroke circuit. The keyboard is locked and

so invalid, but the remote control is working normally.

Check whether the keystroke can’t

get up with prssure.

YES

NO

PCB is broken, replace a new PCB.

Repair the keystrokes on electrical

box to keep them away from the

keystrokes on PCB.
