1 Safety precaution
1.1 Installation
For electrical work, contact the dealer, seller, a qualified electrician, or an Authorized service
center.
Do not disassemble or repair the product by yourself.
Sharp edges could cause injury, be especially careful of the case edges and the fins on the
condenser and evaporator.
Be sure the installation area does not deteriorate with age.
Take care to ensure that power cable could not be pulled out or damaged during operation.
Do not place anything on the power cable.
Do not plug or unplug the power supply plug during operation.
Do not store or use flammable gas or combustible near the product.
When flammable gas leaks, turn off the gas and open a window for ventilation before turn the
product on.
If strange sounds, or small or smoke comes from product. Turn the breaker off or disconnect the
power supply cable as soon as possible.
When the product is soaked (flooded or submerged), contact an Authorized service center.
Be caution that water could not enter the product.
Turn the main power off when cleaning or maintaining the product.
When the product is not be used for a long time, disconnect the power supply plug or turn off the
breaker.
1.2 Caution
Always check for gas (refrigerant) leakage after installation or repair of product.
Install the drain hose to ensure that water is drained away properly.
Keep level even when installing the product.
Do not install the product where the noise or hot air for the outdoor could damage the
neighborhoods.
Use two or more people to lift and transport the product.
Do not install the product where it will be exposed to sea wind (salt spray) directly.
1.3 Operational
Do not expose the skin directly to cool air for long periods of time. (Do not sit in the draft). Do
not use the product for special purposes, such as preserving foods, works of art, etc. It is a
consumer air conditioner, not a precision refrigerant system.
Do not block the inlet or outlet of air flow.
Use a soft cloth to clean. Do not use harsh detergents, solvents, etc.
Do not touch the metal parts of the product when removing the air filter. They are very sharp.
Do not step on pr put anything on the product.
Always insert the filter securely. Clean the filter every two weeks or more often if necessary.
Do not insert hands or other object through air inlet or outlet while the product is
operated.
Do
not drink the water drained from the product.

Specification
2
Replace the all batteries in the remote control with new ones of the same type. Do not mix old and
mew batteries or different types of batteries.
Do not recharge or disassemble the batteries. Do not dispose of batteries in a fire.
If the liquid from the batteries gets onto your skin or clothes, wash it well with clean water. Do not
use the remote of the batteries have leaked.
1.4 Attention
For effective cooling functions, please ensure that the following steps are undertaken:
Extend the exhaust hose to a length of not more than 400mm.
The exhaust hose must be kept parallel and must not be bent
up or down.
A distance of 500mm minimum must kept between the
filter side of the unit.
