Warning

1. Site Safety

3. Installation Safety

Please note:

Using Your Air Conditioner

The installation site should be in a well-ventilated condition.

The sites for installing and maintaining an air conditioner using Refrigerant R32 should be free from open fire

or welding, smoking, drying oven or any other heat source higher than 548 C/1018F which easily produces

open fire.

When installing an air conditioner, it is necessary to take appropriate anti-static measures such as wear anti-

static clothing and/or gloves.

It is necessary to choose the site convenient for installation or maintenance wherein the air inlets and outlets

of the indoor and outdoor units should be not surrounded by obstacles or close to any heat source or

combustible and/or explosive environment.

If the indoor unit suffers refrigerant leak during the installation, all the personnel should go out till the

refrigerant leaks completely for 15 minutes. If the product is damaged, it is a must to carry such damaged

product back to the maintenance station and it is prohibited to weld the refrigerant pipe or conduct other

operations on the user's site.

It is necessary to choose the place where the inlet and outlet air of the indoor unit is even.

It is necessary to avoid the places where there are other electrical products, power switch plugs and sockets,

kitchen cabinet, bed, sofa and other valuables right under the lines on two sides of the indoor unit, and also

prevent mechanical damage from occurring.

Normal Operating Sounds

You may hear a pinging noise caused by water hitting the condenser, on rainy days, or when the

humidity is high. This design feature helps remove moisture and improve efficiency.

You may hear the thermostat click when the compressor cycles on and off.

Water will collect in the base pan during rain or days of high humidity. The water may overflow and

drip from the outside part of the unit. The fan may run even when the compressor is not on.

hand side of the sleeve, in a clear area about 3 inches max

deep from the front edge as below.

b, Fasten the grounding wire with screw to the drilled hole,

and pull the loose end of the ground wire out of the front of

the sleeve and bend it away from the opening. This will be

attached to the air conditioner once installed.
