Safety Precautions

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
andwork 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.

Recognize the following safety information:

Incorrect handling could result in
personal injury or death.

Incorrect handling may result in
minor injury,or damage to product
or property.

Warning

Caution

Caution

Warning

All electric work must be performed by a licensed technician
according to local regulations and the instructions given in
this manual.

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.

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.

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.

Have all wiring connected tightly. Loose connection may
lead to overheating and a possible fire hazard.

Make sure the outdoor unit is installed on a stable, level
surface with no accumulation of snow, leaves, or trash
beside.

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.

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.

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.

Properly insulate any tubing running inside the room to
prevent the water from damaging the wall.

1.Safety Precautions

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.

Should any emergency occur, stop the unit and discon­nect the power immediately.

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.
