1. THE FOLLOWING SHOULD ALWAYS BE
OBSERVED FOR SAFETY
•
Be sure to read “THE FOLLOWING SHOULD ALWAYS BE 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 OPERATING
INSTRUCTIONS in a handy place on the customer’s site.
WARNING
■
Do not install the unit by yourself (customer).
Incomplete installation could cause injury due to fire, electric shock, the unit
falling or leakage of water. Consult the dealer from whom you purchased the
unit or special installer.
■
Install the unit securely in a place which can bear the weight of the unit.
When installed in an insufficient strong place, the unit could fall causing injury.
■
Use the indoor/outdoor unit connecting wire that meets the Standards to
connect the indoor and outdoor units and fix the wire to the terminal
block securely so that no external force is conveyed to the connecting
section of the terminal block.
Incomplete connection or fixing of the wire could result in a fire.
■
Do not use intermediate connection of the power cord or the extension
cord and do not connect many devices to one AC outlet.
It could cause a fire or an electric shock due to defective contact, defective
insulation, exceeding the permissible current, etc.
■
Check that the refrigerant gas do not leak after installation has com-
pleted.
If refrigerant gas leaks indoors, and comes into contact with the fire of a fan
heater, space heater, stove, etc., harmful substances will be generated.
■
Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric
shock, the unit falling or leakage of water.
■
Perform electrical work according to the installation manual and be sure
to use an exclusive circuit.
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.
■
Attach the electrical cover to the indoor unit and the service panel to the
outdoor unit securely.
If the electrical cover in the indoor unit and/or the service panel in the outdoor
unit are not attached securely, it could result in a fire or an 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 due to a fire, an electric
shock, the unit falling, leakage of water, etc.
■
Be sure to cut off the main power in case of setting up the indoor
electronic control P.C. board or wiring works.
It could cause an electric shock.
CAUTION
■
Perform grounding.
Do not connect the ground wire to a gas pipe, water pipe, lightning rod or
telephone ground wire. Defective grounding could cause an electric shock.
■
Do not install the unit in a place where an inflammable gas leaks.
If gas leak and accumulate in the area surrounding the unit, it could cause an explosion.
■
Install a ground leakage breaker depending on the installation place
(Where it is humid).
If a ground leakage breaker is not installed, it 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.
■
Fasten a flare nut with a torque wrench as specified in this manual.
When fastened too tight, a flare nut may broken after a long period and cause
a leakage of refrigerant.
2. SELECTING THE INSTALLATION LOCATION
2-1 INDOOR UNIT
•
Where airflow is not blocked.
•
Where cool air spreads over the entire room.
•
Maximum refrigerant piping length between indoor unit and outdoor unit is 50 ft.
and the difference of height of both units is 25 ft. max.
•
Rigid wall without vibration.
•
Where it is not exposed to direct sunshine.
•
Where easily drained.
•
At a distance 3 ft. or more away from your TV and radio (to prevent picture from
being distorted or noise from being generated).
•
In a place as far away as possible from fluorescent and incandescent lights (so
the infrared remote control can operate the air conditioner normally).
•
Where the air filter can be removed and replaced easily.
2-2 OUTDOOR UNIT
•
Where it is not exposed to strong wind.
•
Where airflow is good and dustless.
•
Where it is not exposed to rain or direct sunlight.
If a suitable place cannot be found, use a blind or cover to block the sunlight.
•
Where neighbours are not annoyed by operation sound or hot air.
•
Where rigid wall or support is available to prevent the increase of operation sound
or vibration.
•
Where there is no risk of combustible gas leakage.
•
When installing the unit at a high level, be sure to fix the unit legs.
•
Where it is at least 10 ft. away from the antenna of TV set or radio. (Otherwise,
images would be disturbed or noise would be generated.)
•
Where it will not be buried in snow.
•
Install the unit horizontally.
Note:
See FREE SPACE REQUIRED AROUND OUTDOOR UNIT in 3. INSTALLATION
DIAGRAM & ACCESSORIES for the details of required installation space.
CAUTION
Avoid the following places for installation where air conditioner trouble is liable to occur.
•
Where flammable gas could leak.
•
Where there is much machine oil.
•
Salty places such as the seaside.
•
Where sulfide gas is generated such as a hot spring.
•
Where there is high-frequency or wireless equipment.
2-3 WIRELESS REMOTE CONTROLLER MOUNTING
•
Place of mounting
•
Where it is easy to operate and easily visible.
•
Where children can not touch.
•
Mounting
Select a position about 4 ft. above the floor, check that signals from the remote
controller are surely received by the indoor unit from that position (‘beep’ or ‘beep-
beep’ receiving tone sounds). After that, attach remote controller holder
3
to a
pillar or wall and set the wireless remote controller
6
.
In rooms where inverter type fluorescent lamps are used, the signal from the
wireless remote controller may not be received.
