• 

Be careful to avoid water entering the unit.

There is an increased risk of fi re, electric shock, or product 
damage.

• 

Ventilate the product from time to time when operating 
it in conjunction with a stove etc.

Not doing so may increase the risk of fi re, electric shock, or 
product damage.

• 

Turn the main power off when cleaning or maintaining 
the product.

Not doing so may increase the risk of fi re, electric shock, or 
product damage.

• 

When the product is not be used for a long time, 
disconnect the power supply plug or turn off the circuit 
breaker.

Doing so will minimise the risk of product damage or failure, or 
unintended operation.

• 

Take care to ensure that nobody can step on or fall onto 
the outdoor unit.

This could result in personal injury and product damage.

❯ 

CAUTION

• 

Always check for gas (refrigerant) leakage after 
installation or repair of product.

Low refrigerant levels may cause unit failure.

• 

Install the drain hose correctly to ensure that water is 
drained away properly.

A bad connection may cause water leakage.

• 

Keep unit level even when installing the product.

This will avoid vibration or any leakages from the unit.

• 

Do not install the product where noise or hot air 
emissions from the outdoor unit could adversely affect 
your neighbour.

• 

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.

It may cause corrosion to the product. Corrosion, particularly 
on the condenser and evaporator fi ns, could cause product 
malfunction or ineffi cient operation.

OPERATIONAL CONSIDERATIONS

• 

Do not expose the skin directly to cool air for long 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-use air conditioner, not a precision 
refrigeration system. Incorrect use may increase the risk of 
damage or loss of property.

• 

Do not block the air inlet or outlet vents.

• 

Use a soft cloth to clean. Do not use harsh detergents, 
solvents, etc.

Incorrect cleaning methods may increase the risk of fi re, 
electric shock, or damage to the plastic parts of the product.

• 

Do not touch the metal parts of the product when 
removing the air fi lter. They are very sharp.

• 

Do not climb onto or use the outdoor units as a shelf as 
the brackets may not carry the additional weight.

• 

Always insert the fi lter securely. Clean the fi lter every 
two weeks or more often if necessary.

A dirty fi lter reduces the effi ciency of the air conditioner and 
could cause product malfunction or damage.

• 

Do not insert hands or other objects through air inlet or 
outlet while the unit is use.

• 

Do not drink the water drained from the unit.

• 

Use a fi rm stool or ladder when cleaning or maintaining 
the product.

Be careful and avoid personal injury.

• 

Replace all the batteries at the same time in the remote 
control with new ones of the same type. Do not mix old 
and new batteries or different types of batteries.

• 

Incorrect battery usage increases the risk of fi re or 
explosion.

• 

Do not recharge or break down the batteries. Do not 
dispose of batteries in a fi re.

They may explode.

• 

If the liquid from the batteries gets onto your skin or 
clothes, wash thoroughly with clean water. Do not use 
the remote control if the batteries have leaked.
