1.Safety Precautions

Safety Precautions

Caution

Warning

Caution

could result in

personal injury or death.

Incorrect handling

result in

injury, or damage to product

or property.

Incorrect handling may

minor

Recognize the following safety information:

Installing, starting up, and servicing air conditioner can be

hazardous due to system pressure, electrical components, and

equipment location, etc.

Only trained, qualified installers and service personnel are

allowed to install, start-up, and service this equipment.

Untrained personnel can perform basic maintenance functions

such as cleaning coils. All other operations should be

performed by trained service personnel.

When handling the equipment, observe precautions in the

manual and on tags, stickers, and labels attached to the

equipment. Follow all safety codes. Wear safety glasses and

work gloves. Keep quenching cloth and fire extinguisher nearby

when brazing.

Read the instructions thoroughly and follow all warnings or

cautions in literature and attached to the unit. Consult local

building codes and current editions of national as well as local

electrical codes.

All electric work must be performed by a licensed technician

according to local regulations and the instructions given in this

manual.

Never supply power to the unit unless all wiring and tubing

are completed, reconnected and checked.

This system adopts highly dangerous electrical voltage.

Incorrect connection or inadequate grounding can cause

personal injury or death. Stick to the wiring diagram and all

the instructions when wiring.

Have the unit adequately grounded in accordance with

local electrical codes.

Have all wiring connected tightly. Loose connection may

lead to overheating and a possible fire hazard.

All installation or repair work shall be performed by your dealer

or a specialized subcontractor as there is the risk of fire, electric

shock, explosion or injury.

Make sure the ceiling/wall is strong enough to bear the

weight of the unit.

Make sure the noise of the outdoor unit does not disturb

neighbors.

Properly insulate any tubing running inside the room to

prevent the water from damaging the wall.

Make sure the outdoor unit is installed on a stable, level

surface with no accumulation of snow, leaves, or trash

beside.

Follow all the installation instructions to minimize the risk

of damage from earthquakes, typhoons or strong winds.

Avoid contact between refrigerant and fire as it generates

poisonous gas.

Apply specified refrigerant only. Never have it mixed with

any other refrigerant. Never have air remain in the

refrigerant line as it may lead to rupture and other hazards.

Make sure no refrigerant gas is leaking out when

installation is completed.

Should there be refrigerant leakage, the density of

refrigerant in the air shall in no way exceed its limited

value, or it may lead to explosion.

Before installing, modifying, or servicing system, main

electrical disconnect switch must be in the OFF position.

There may be more than 1 disconnect switch. Lock out and

tag switch with a suitable warning label.

Keep your fingers and clothing away from any moving

parts.

Clear the site after installation. Make sure no foreign

objects are left in the unit.

Always ensure effective grounding for the unit.

Never install the unit in a place where a combustible gas

might leak, or it may lead to fire or explosion.

Make a proper provision against noise when the unit is

installed at a telecommunication center or hospital.

Provide an electric leak breaker when it is installed in a

watery place.

Never wash the unit with water.

Handle unit transportation with care. The unit should not be

carried by only one person if it is more than 20kg.

Never touch the heat exchanger fins with bare hands.

Never touch the compressor or refrigerant piping without

wearing glove.

Do not have the unit operate without air filter.

Should any emergency occur, stop the unit and disconnect

the power immediately.
