For the usage safety of the air conditioner, the units should be earthed reliably .Do not connect the earth

line with the gas pipe, water pipe, drainage pipe or other places that specialized personnel considers unsafe.

◆

Air conditioner must use special power supply circuit and switches for creepage protect and air with

enough capacity should be installed in the circuit.

◆

Ensure that the connecting of power cord is normal, otherwise, electric shock or re may happened.

◆

Do not cut off the power supply to turn off the unit when it is running, otherwise life time of units may

shortened.

◆

Do not mangle wire or adopts wires that are not recommend to use, otherwise, electric shock or re

may happened.

◆

Please don’t operate the unit by wet hand, or electric shock may happened.

◆

Don’t insert nger or stick like things into outlet vent, otherwise, damage may be happened.

◆

Cut down the main power switch immediately if malfunction (such as smell the burning odor etc.)

happen, and then contact the special engaged maintenance center. If the abnormal state is maintained, the unit

may be damaged or electric shock or re may be happened.

◆

Operating Instructions

＊

The temperature should not be set lower

than what you need. This would lead to increase

energy cost.

＊

To distribute cool air throughout the room,

adjust airow direction as shown by the arrows

(see picture) to diffuse cool air.

＊

Clean the air lter every week for higher

efciency by professional.

＊

Close window and door while operating the

unit to prevent leakage of cooled air and save

energy.

＊

Draw close curtains or close glass windows

when cooling to prevent heat load from sun

light which may cause more electricity cost.

＊

In case of ineffective ventilation, open the

window to ventilate the room air once in a

while but not too long since cooled air will be

uselessly drained out.

Page 38

＊

Turn off the air conditioner if, while the air

conditioner is running, electricity interference

occurs. If the unit is not to be used for a long

time, cut off the power supply main switch.

＊

Chec k elec t rical sy stem (v oltag e and

frequency). Use the power supply indicated

on the unit to operate the air conditioner and

only fuses with specied capacity it should be

done by professional. Do not use pieces of wire

instead of fuse.

＊

Do not insert objects into the air inlet or

outlet when the air conditioner is running as it

may cause damage or personal injury. Also pay

special attention when children are around.

＊

Do not locate any obstacle against the air

flow direction of indoor and outdoor unit.

Otherwise, it can cause inefcient performance

or malfunction.

＊

Do not channel the airow directly at people,

especially infants, aged persons, or patients.

＊

Do not locate a heater or any other heat

source close to the unit. The heat may deform

plastic parts.
