• Be sure to read "THE FOLLOWING SHOULD BE ALWAYS OBSERVED FOR SAFETY" before installing the air
conditioner.
• Be sure to observe the cautions specified here as they include important items related to safety.
• The indications and meanings are as follows.
WARNING
Could lead to death, serious injury, etc.
CAUTION
Could lead to serious injury in particular environments when operated incorrectly.
• After reading this manual, be sure to keep it together with the instruction manual in a handy place .
WARNING
Do not install it yourself (customer).
Perform the installation securely referring to the installation manual.
• Incomplete installation could cause injury due to fire, electric shock, the unit
falling or a leakage of water. Consult the dealer from whom you purchased the
unit or special installer.
• Incomplete installation could cause a personal injury due to fire, electric
shock, the unit falling or a leakage of water.
Install the unit securely in a place which can bear the
weight of the unit.
Perform electrical work according to the installation
manual and be sure to use an exclusive circuit.
• When installed in an insufficient strong place, the unit could fall causing
injured.
• If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock.
Use the specified wires to connect the indoor and the
outdoor units securely and attach the wires firmly to the
terminal board connecting sections so the stress of the
wires is not applied to the sections.
Attach the electrical part cover to the indoor unit and the
service panel to the outdoor unit securely.
• Incomplete connecting and fixing could cause fire.
Check that the refrigerant gas do not leak after installation
is completed.
• If the electrical part cover if the indoor unit and/or the service panel if the outdoor unit are not attached securely, it could result in a fire or electric shock
due to dust, water, etc.
Be sure to use the part provided or specified parts for
the installation work.
• The use of defective parts could cause an injury or leakage of water due to a
fire, electric shock, the unit falling, etc.
CAUTION
Perform grounding
• Do not connect the ground wire to a gas pipe, water pipe arrester
or telephone ground wire. Defective grounding could cause an
electric shock.
Perform the drainage/piping work securely
according to the installation manual.
• If there is a defect in the drainage/piping work, water could drop
from the unit and household goods could be wet and damaged.
Do not install the unit in a place where an inflammable gas leaks.
• If gas leaks and accumulates in the area surrounding the unit,
it could cause an explosion.
❈ The installation parts which are not provided should be purchased.

• Select and mark the position for fixing bolts and piping hole.
• Decide the position for fixing bolts slightly tilted to the drain
direction after considering the direction of drain hose.
• Drill the hole for anchor bolt on the wall.
NOTE:
• Avoid the following installation location.
1. Such places as restaurants and kitchen where considerable amount of oil steam and flour is generated.
These may cause heat exchange efficiency reduction, or water drops, drain pump mal-function.
In these cases, take the following actions;
• Make sure that ventilation fan is enough to cover all noxious gases from this place.
• Ensure enough distance from the cooking room to install the air conditioner in such a place where it may
not suck oily steam.

Use the clip (accessory)
• 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.
• Be sure to check the drain pump for normal
operating and noise when electrical wiring
is complete.
• When the test is complete, connect the
flexible drain hose to the drain port on the
indoor unit.

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power specialized for the air conditioner. As for the method of
wiring, be guided by the circuit diagram pasted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screw 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 give rise to burn-out
of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to
the normal function of a overload protection device.
• Proper starting power is not given to the compressor.
HAND OVER
Teach the customer the operation and maintenance procedures, using the operation manual (air filter cleaning, temperature
control, etc.).

Installation of remote control
• Although the room themperature sensor is in the indoor unit, the remote control should be installed in such
places away from direct sunlight and high humidity.
Installation of the remote control
• Select places that are not splashed with water.
• Select control position after receiving customer approval.
• The room temperature sensor is built in the indoor unit.
• This remote control equipped with liquid crystal display. If this position is higher or lower, display is difficult to
see.(The standard height is 1.2 ~1.5m high)
Routing of the remote control cord
• Keep the remote control cord away from the refrigerant piping and the drain piping.
• To protect the remote control cord from electrical noise, place the cord at least 5cm away from other power
cables (audio equipment. television set, etc.)
• If the remote control cord is secured to the wall, provide a trap at the top of the cord to prevent water droplets
from running.
CAUTION
• Use the wireless remote control with the wired.
If you want to use wireless alone, you should do following process.
1) Do auto addressing in connecting the wired.
2) After compelting auto addressing, turn off the power and disconnect the wired.

Indoor Unit Drain Pipe Work
Indoor unit drain pipe work
1) Drain pipe gradient and support
a) - The drain pipe must be fitted at a gradient of at least 1/100.
- The drain pipe should be as short as possible and free from airlocks.
Indoor unit
Gradient of least 1 / 100
(1cm / 1m)
b) - Suspension bolts should be used th support long stretches of drain pipe in order to ensure that a
gradient of 1/100 is maintained (PVC pipe should not be bent)
Spacing of supports for horizontal piping
Class
Norminal diameter
Spacing

c) - The length of pipe laid horizontally should be kept a minimum.
2) Drain trap
Fit any indoor unit whose drain pipe connection is subjected to negative pressure, with a drain trap.
a) Rig the drain trap shown in the drawing below.

3) Ground drain piping
a) It is standard work practice to make connections to the main pipe from above. The pipe down from the
combination should be as large as possible.

b) The pipe work should be kept as short as possible and he number of indoor units per group kept to a
minimum.
4) Use of an auxiliary drain hose(flexible)
a) It the drain pan made of polystyrene foam is used then an auxiliary drain hose(flexible) is also essential a
flexible drain hose permits the drain socket and drain pipe to be connected without difficulty and prevents
any undue strain being placed on he drain pan.

❈ Important points
- The drain pipe should be at least equal in size to that of the indoor unit.
- The drain pipe is thermally insulated to prevent the formation of condensation inside the pipe.
- The drain up mechanism should be fitted before the indoor unit is installed and when the electricity has
been connected some water should be added to the drain pan and the drain pump check to see that it is
functioning correctly.
- Al connections should be secure. (Special care is needed with PVC pipe)
- Insulate auxiliary drain hose with thermal insulation band.
