To prevent injury to the user or other people and property damage, the
following instructions must be followed.
Incorrect operation due to ignoring of instructions may cause harm or
damage. The seriousness is classified by the following indications.
1. Connect with the power properly.
Otherwise, it may cause electric
shock or fire due to excess heat
generation.
2. Always ensure effective grounding.
No grounding may cause electric
shock.
3. Disconnect the power if strange
sounds, smell, or smoke comes
from it. It may cause fire and
electric shock.
4. Do not operate or stop the unit by
switching on or off the power. It
may cause electric shock or fire due
to heat generation.
5. Do not operate with wet hands or in
damp environment. It may cause
electric shock.
6. Do not allow water to run into
electric parts. It may cause failure of
machine, electric shock or fire.
7. Do not use the power cord near
flammable gas or combustibles,
such as gasoline, benzene, thinner,
etc. It may cause an explosion or fire.
9.Do not damage or use an
unspecified power cord. It may
cause electric shock or fire.
10.Do not place heavy object on the
power cord and ensure that the
cord will not be compressed. There
is danger of fire or electric shock.
8. Do not use the power cord close to
heating appliances. It may cause
fire and electric shock.

11.Do not open the unit during
operation. It may cause electric
shock or injury.
12.Do not drink water drained
from air conditioner. It contains
contaminants and could make
you sick.
13.Do not disassemble or modify unit.
It may cause failure of appliance
and electric shock.
14.When the air filter is to be
removed, do not touch the metal
parts of the unit. It may cause an
injury.
15.When the unit is to be cleaned,
switch off, and turn off the circuit
breaker. Do not clean unit when
power is on as it may cause fire,
electric shock or injury.
16.Avoid direct exposure of occupants
to air flow.
17.Turn off the main power switch when
not using the unit for a long time.
18.The air conditioner may be dusted
with an oil free cloth, or washed
with a cloth dampened in a solution
of warm water and mild dishwashing
detergent. Rinse thoroughly and wipe
dry. Wring excess water from cloth
before wiping around controls.
20.Always insert the filters securely.
Clean filter once every two weeks.
Operation without filters may
cause failure.
21.Always install circuit breaker and a
dedicated power circuit. No
installation may cause fire and
electric shock.
19.Ensure that the installation bracket of
the outdoor unit will not damage
due to prolonged exposure. If
bracket damages, there will be
concern of damage due to falling
of unit.
22.Do not place obstacles around air-
inlets or inside of air-outlet. It may

Outdoor unit installation
1. Install the outdoor part of the unit
on a rigid surface to avoid excess
noise and vibration.
2. Direct the air vent toward an area
without obstacles.
3. Install the unit at the site where it is
to as little wind as possible,
exposed
especially in areas where it is
frequently windy.
4. If the installation site is exposed to
heavy winds, such as in coastal
areas, place the unit along the
widest part of the wall or use
protective plates.
5. Be sure there is no obstacle which
blocks radiating air, including
schrubs or bushes.

Connecting (Power and Control Cable)
The main power is supplied to the outdoor unit. The field supplied connecting cable from the outdoor unit to indoor unit consists of four
wires and provides the power for the indoor unit as well as the communication signal and ground between the outdoor and indoor unit.
Two wires are high voltage AC power, one is low voltage DC signal and one is a ground wire.
Consult local building codes, NEC (National Electrical Code) or CEC (Canadian Electrical Code) for special requirements.

Caution
After the confirmation of the above conditions, prepare the wiring as follows:
1. Never fail to have an individual power circuit specifically for the air
conditioner. As for the method of wiring, be guided by the circuit diagram
posted on the inside of control cover.
2. The screws which fasten the wiring in the casing of electrical fittings are
liable to come loose from vibrations to which the unit is subjected during
the course of transportation. Check them and make sure that they are all
tightly fastened. (If they are loose, it could cause burn-out of the wires.)
3. Specification of power source.
4. Confirm that electrical capacity is sufficient.
5. See to that the starting voltage is maintained at more than 90 percent of
the rated voltage marked on the name plate.
6. Confirm that the cable thickness is as specified in the power source
specification.
7. Always install an earth leakage circuit breaker in a wet or moist area.
8. The following would be caused by voltage drop: vibration of a magnetic
switch, which will damage the contact point, fuse breaking, disturbance of
the normal function of the overload protector.
9. The means for disconnection from a power supply shall be incorporated
in the fixed wiring and have an air gap contact separation of at least 1/8 inch
in each active (phase) conductors.
Air purging
Air and moisture in the refrigeration system have undesirable effects as indicated
below:
1. Pressure in the system rises.
2. Operating current rises.
5. Water may lead to corrosion of
parts in the refrigeration system.
Therefore, the indoor unit and tubing
between the indoor and outdoor unit
must apply leakage test and be evacuated
to remove any noncondensables and
moisture from the system.
3. Cooling or heating(only for
models with heating function)
efficiency drops.
4. Moisture in the refrigerant circuit
may freeze and block capillary
tubing.

Electrical safety
Perform the electric safety check after completing installation:
1. Insulated resistance: The insulated resistance must be more than 2M .
2. Grounding work: After finishing grounding work, measure the grounding
resistance by visual detection and grounding resistance tester. Make sure the
grounding resistance is less than 4 .
3. Electrical leakage check (performing during test running): During test operation
after finishing installation, the serviceman can use the electric probe and
multimeter to perform the electrical leakage check. Turn off the unit
immediately if electrical leakage happens. Check and find out the solution
ways till the unit operates properly.
