• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air
conditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

• For installation of the product, always contact the service center or a professional installation
agency. - Otherwise, it may cause a fire, electrical shock, explosion or injury.

• Securely attach the electrical part cover to the indoor unit and the service panel to the outdoor unit.

- If the electrical part cover of the indoor unit and the service panel of the outdoor unit are not

attached securely, it could result in a fire or electric shock due to dust, water, etc.

• Always install an earth leakage circuit breaker and a dedicated switching board. - No installation may
cause a fire and electrical shock.

• Do not keep or use flammable gases or combustibles near the air conditioner. - Otherwise, it may
cause a fire or the failure of product.

• Ensure that an installation frame of the outdoor unit is not damaged due to use for a long time.

- It may cause injury or an accident.

• Do not disassemble or repair the product randomly. - It will cause a fire or electrical shock.

• Do not install the product at a place that there is concern of falling down. - Otherwise, it may result
in personal injury.

• Use caution when unpacking and installing. - Sharp edges may cause injury.

• Use a vacuum pump or Inert (nitrogen) gas when doing leakage test or air purge. Do not compress
air or Oxygen and Do not use Flammable gases. Otherwise, it may cause fire or explosion. There is
the risk of death, injury, fire or explosion.

• Consult your lacal dealer regarding what to do in case of refrigerant leakage.
When the air conditioner is to be installed in a small room, it is necessary to take proper measures
so that the amount of any leaked refrigerant does not exceed the concentration limit in the event of
a leakage. Otherwise, this may lead to an accident due to oxygen depletion.

• Carry out the specified installation work after taking into account earthquakes.
Failure to do so during installation work may result in the unit falling and causing accidents.

Indoor Unit Drain Piping

- Drain piping must have down-slope (1/50 to
1/100): be sure not to provide up-and-down
slope to prevent reversal flow.

- During drain piping connection, be careful
not to exert extra force on the drain port on
the indoor unit.

- The outside diameter of the drain connection
on the indoor unit is 32 mm.

Piping material: Polyvinyl chloride pipe VP-25
and pipe fittings

- Be sure to execute thermal insulator on the
drain piping.

- Install the drain raising pipes at a right
angle to the indoor unit and no more than
300 mm from the unit.

Thermal insulator material: Polyethylene foam
with thickness more than 8 mm.

Drain test

- Connect the main drain pipe to the exterior
and leave it provisionally until the test comes
to an end.

- Feed water to the flexible drain hose and
check the piping for leakage.

- When the test is complete, connect the
flexible drain hose to the drain port on the
indoor unit.

1 Remove the air filter.

2 Check the drain.

- Spray one or two glasses of water upon
the evaporator.

- Ensure that water flows drain hose of

Thermal insulator

1 Use the thermal insulator material for the

refrigerant piping which has an excellent
heat-resistance (over 120 °C).

2 If this air conditioner is operated for a long

time in high humid atmosphere (dew point
temperature: more than 23 °C), water
drops are liable to fall. In this case, add
thermal insulator material according to the
following procedure:

- Thermal insulation material to be
prepared... Adiabatic glass wool with
thickness 10 to 20 mm.

- Stick glass wool on all air conditioners
that are located in ceiling atmosphere.

Wiring Connection

- Open the control box cover and connect the
Remote controller cable and Indoor power
wires.

- Remove the control box cover for electrical
connection between the indoor and outdoor
unit. (Remove screws ①.)

- Use the cord clamper to fix the cable.

Precautions when laying power wiring
Use round pressure terminals for

connections to the power terminal block.

When none are available, follow the
instructions below.

• Do not connect wiring of different
thicknesses to the power terminal
block. (Slack in the power wiring may
cause abnormal heat.)

• When connecting wiring which is the
same thickness, do as shown in the
figure below.

• For wiring, use the designated power
wire and connect firmly, then secure to
prevent outside pressure being exerted
on the terminal block.

• Use an appropriate screwdriver for
tightening the terinal screws. A
screwdriver with a small head will strip
the head and make proper tighterning
impossible.

• Over-tightening the terminal screws
may break them.

INSTALLATION INSTRUCTION

1 Please fix tightly using provided screw

after placing remote controller setup board
on the place where you like to setup.

- Please set it up not to bend because poor
setup could take place if setup board
bends.
Please set up remote controller board fit
to the reclamation box if there is a
reclamation box.

2 Can set up wired remote controller cable

into three directions.

- Set up direction: the surface of wall
reclamation, upper, right

- If setting up remote controller cable into
upper and right side, please set up after
removing remote controller cable guide
groove.

* Remove guide groove with long nose.

① Reclamation to the surface of the wall
② Upper part guide groove
③ Right part guide groove

3 Please fix remote controller upper part into

the backplate attached to the surface of
the wall, as the picture below, and then,
connect with backplate by pressing lower
part.

- Please make sure to leave no gaps on the
top, bottom, left or right sides between
the remote controller and backplate.

- Before assembly with the backplate,
arrange the Cable not to interfere with
circuit parts.

Remove remote controller by inserting a
screwdriver into the lower separating holes
and twisting to release the controller from
backplate.

- There are two separating holes. Please
individually separate one at a time.

- Please be careful not to damage the
inside components when separating.

4 Please refer to the following directions

when connecting the indoor unit and the
wired remote controller together.

- Please connect the cables as shown in
the figure below when connecting the
plug type cable from the indoor unit’s
C/BOX and the housing type of the
extension cable.

Please use an extension cable if the distance
between the wired remote controller and the
indoor unit is longer than 10 m(32 ft).

14

INSTALLATION INSTRUCTION

ENGLISH

• When installing the wired remote
controller, do not bury it in the wall. (It
can cause damage in the temperature
sensor.)

• Do not install the cable to be 50 m(164 ft)
or longer. (It can cause communication
error.)

Remote controller installation

Since the room temperature sensor is in the remote controller, the remote controller box should
be installed in a place away from direct sunlight, high humidity and direct supply of cold air to
maintain proper space temperature. Install the remote controller about 5 ft(1.5 m) above the floor
in an area with good air circulation at an average temperature.

Do not install the remote controller where it can be affected by:

- Drafts, or dead spots behind doors and in corners.

- Hot or cold air from ducts.

- Radiant heat from sun or appliances.

- Concealed pipes and chimneys.

- Uncontrolled areas such as an outside wall behind the remote controller.

- This remote controller is equipped with LCD. display. For proper display of the remote controller
LCD's, the remote controller should be installed properly as shown in Fig.1.
