weight of the unit.
Adequate wall support for weight of air conditioner.
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.
Warning
ll electric work must be performed by a licensed technician
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.
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,
Caution
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.
Properly insulate any tubing running inside the room to
prevent the water from damaging the wall.

where there is strong electromagnetic interference.
How to Install
● Choose a location where there is not any obstacle surrounding the unit.
● Prepare the installation hole a little bigger than the size of the unit.
● Choose the installation space according to the diagrams in Part 3 Outline and Installation Dimension.
Installation
Remove the sticker from the front panel.
Put the unit into the installation hole.
● When installing, make sure the unit is slanted downward to the back to
minimize the nosie and vibration of operation. (Slant by 6-10mm.)
(See the right figure)
● Make sure the installation place is strong enough to minimize the noise
and vibration of operation.
Fill the gaps in the cabinet with sponge or foam.

Electrical Wiring
●
Make sure the unit is reliably grounded.
●
Adopt an exclusive circuit for the unit. Never apply removable socket, or the poor
contact between them may lead to overheating or fire.
●
Never pull the power cord with excessive force.
●
In a fixed circuit, make sure there is electricity leakage protection switch with leakage
current less than 30mA.
●
Connection between air conditioner and its power cord, as well as between individual
elements should be in accordance with the wiring diagram on the unit.
●
Make sure the air conditioner is installed in accordance with national wiring regulation.
●
Adopt an all-pole disconnection switch with a minimum contact separation of 3mm in all poles
in a fixed wiring
●
Make sure an air switch (thermal-magnetic breaker) is installed in the circuit.
●
Damaged power cord should be replaced by the manufacturer, an authorized dealer
or a qualified person for fear of hazards.
