• Complete the grounding engineering according to the Electrical Safety Regulations to avoid leakage.

• The machine needs to be used with special power supply. Don’t share the circuit with other equipment.

• The machine should be fastened at the place of flatness and good ventilation and keep proper distance

with surrounding.

• Keep the machine away from fire and pollutant.

• It is not recommended to place the machine under the sun and rain.

• Keep the children away from the machine.

• Random change of specification by user is not allowed.

• It is prohibited to us e the volat ile s ol vent , volat ile oi l, tolu ene an d ot her c hemic als be sid es or ab ove the

machine.

• Make sure the machine doesn’t put on the cable, and the cable is comp lete ly f ine , in case of a ny d ang er

of leakage and fire.

• Don’t operate or repair the machine with wet hands.

• Under no conditions should users repair the machine by themselves. Only the professionals are au-

thorized to repair the machine, it may result in personal injury or more serious problem to the equip­ment.

• Don’t wash the machine directly with water or cleanser. Need to scrub by cloth with water or mild de-

tergent.

• For avoiding machine breakdown or any danger, it is prohibited to insert objects into the air outlet.

Power cord

Specification 3 X 1.5 mm

Model No. 60245 IEC57(YZW)

7.Grounding requirements

1)It is a Class I appliances, be sure to take a reliable grounding.

2)The yellow-green wire is the grounding wire. It must not be used for other purposes and can not be cut.

Do not use
self-tapping screw to prevent the risk of electric shock.

3)Grounding resistance should be in line with the national standard requirement of GB17790.

4)User must provide a reliable grounding power supply. Please do not connect grounding wire to the places

like Water pipe, gas canisters, drain outlet and other unreliable places recognized by professionals.

8.User’s attention

• Set appropriate indoor temperature The indoor temperature should not be set too hi gh or too low, to

make most people feel comfortable. Recommended temperature for cooling is 26-28
heating.

• The window and door should be closed, otherwise, it will affect the effectiveness of air conditioning.

• Equipment like TV, radio and Hi-Fi etc. should be at least one meter away from the indoor machine,

otherwise, they will interfere the image and make noise.

• The power of the machine should be shut down if it is not used for a long time. To protect the machine,

the power should be connected for 24 hours before it is used. If it is shut down in winter, please clean the
machine and dry it. For dustproof, please cover the machine, open the outlet valve to drain out the water
in the heat exchanger and pipes, to prevent frosting. It is recommended to inject antifreeze into the pipes.

• The window should hang up curtains or shutters, to avoid the sun shine directly to the house.

• Dry articles should not be put under the machine, because when the ambient temperature is high or the

drainage is blocked, the machine may drip.

℃, and 18-23℃for

If any abnormity is found (like scorching smell), shut down the power, and contact our
service team, if it is still using in that case, the m achine may be dam aged and cause e lectric
shock or fire, maintenance can only be conducted by professional. The power should be
disconnected before touching the wiring device

The machine can be cleaned only when the power is disconnected, otherwise, it may cause
electric or injury. Don’t wash the machine with water, or it may cause electric shock, Stand
on a firm platform when cleaning ceiling air conditoner
