2 ) Before constructing the installation or transfer.
Do not leave the mounting base being damaged.
The damaged base may cause the falling down of the unit which
may give injury.
Install drain piping (hose) according to
this Installation Manual to ensure proper
drainage.
Improper drain piping (hose) may cause water
leakage and damage to furniture or other possessions.
Do not touch the metal edges inside the unit without
wearing glove on your hands.
Touching directly it may injure your hands.
Do not place objects under the units to avoid damage
of condensation.
When the room is high humidity or when the drain pipe is clogged,
water may drip from the unit.
Never install on the place where a combustible gas
might leak.
The gas may ignite or explode when the gas leaks and collects
in surroundings of the unit.
For special use as for foods, animals/plants, precision
equipment or art objects, the applicability should be
confirmed earlier.
As the use for the applications other than that
designed originally may result in the deterioration
of the quality.
Consult your dealer in this regard.
When the unit is installed at telecommunication centers
or hospitals, take a proper provision against noise.
The erroneous operation of air conditioner may be induced by inverter
equipment, independent power device, medical equipment or
communication equipment.
Do not operate the air conditioner without the air filter
set place.
Dust may accumulate, and cause a failure.
Do not touch the compressor or refrigerant
piping without wearing glove on your hands.
Touching directly such the parts can cause a burn
or frostbite as it becomes high or low temperature
according to the refrigerant state.
Do not handle the switch with wet hands.
Otherwise electric shock can be resulted.
The unit should be securely installed level surface.
When the unit inclines, it causes the water leak and the breakdown.
Please confirm the horizontal with the spirit level.
Do not use the unit under a special atmosphere.
Installing the unit at the following places may cause a trouble,
a place where is much machine oil, salt , humidity or dust,
spa district, a place full of sulfur gas, volatile gas, or corrosive gas,
a place near high frequency processing machine.
Do not wash the unit with water.
If washed with water, electric shock may be caused.
At emergency (if you smell something burning), stop
operation and turn the power source switch off.
Continuing the operation without eliminating the emergency state may
cause a machine trouble, fire, or electric shock.
Do not remove the panel or the fan guard from the unit
when it is running.
You could be injured if you touch rotating, hot or high-voltage parts .
Process the packing material surely.
Be sure to safety dispose the packing materials.
Packing materials, such as catches and other metal or wooden parts,
may cause stabs or other injuries.
Tear off and discard plastic packing bags so that children will not play
any of them.
If children play with a plastic bags which was not torn off, it may cause
a risk of suffocation.
2
The base and attachments of the unit should be periodically
checked for looseness, cracks or other damage.
If such defects are left uncorrected, the unit may fall and cause personal
injury or property damage.
3 ) Before starting.
2. Selection of installed place.
Select space for installing unit, which will meet the following
conditions.
Please pay attention to the refrigerant (Freon gas).
A non flammable, non-toxic, odourless refrigerant is used for this air
conditioner.
The refrigerant is collected on the floor side in the room because the
specific gravity are larger than air. And, it causes the hypoxia accident.
When the refrigerant gas leaks by any chance, the user must ventilates
air enough by stopping the drive of the unit and opening the door.
Place where no direct thermal radiation from other heat sources.
Place where no possibility of short cycle operations caused by exhaust
heat from unit.
Place where no possibility of annoying neighbors by noise from unit.
Place where no exposition to strong wind.
Place where no possibility of snow wind.
Place where with strength which bears weight unit.
Because of the possibility of fire, do not install unit to the space where
generation, inflow, stagnation, and leak of combustible gas is expected.
Avoid unit installation in a place where acidic spray (sulfur) are often used.
Place without dispersion of oil and steam.
Remote controller is not allowed to install for the place
where direct sunshine strikes.
Remote controller should be pushed with finger.
It occasionally causes the electric shock and the breakdown.
Please do not use the unit in the following places.
Place where a lot of oil (The machine oil is contained), moistures,
and dust exist.
Place where a lot of salinity such as beach districts exists.
Place where sulfur gas, volatile gas, and corroded gas are filled.
Place where acid solution is frequently used.
Place where special spray is frequently used.
Hot spring zone.
Near machine (high cycle welding machine etc.) generating high cycle.
Place where ventilation entrance of unit is closed by snowfall.
The main body might corrode when the unit is used in such a place,
the refrigerant leak, the performance of the unit decrease remarkably,
and it cause the damage of parts of the unit.
Be very careful about unit transportation.
When carrying in unit, be sure to support it at four points.
Carrying in and lifting with 3-point support may make unit unstable,
resulting in a fall of it.
The unit should not be carried by only one person if it is more than 20 kg.
It occasionally causes the damage of the unit and health to be impaired.
Some units use PP bands for packing. Do not use any PP band for
delivery purpose. It may cause the injury.
Do not touch the heat exchanger fins with your bare hands.
Doing so may cut your hands.
Do not operate the air conditioner without the eliminator
set place.
Drain may drop into down flow supply duct.
