1. Safety precautions
1.1. Before installation (Environment)
Caution:
• Do not use the unit in an unusual environment. If the air conditioner is
installed in areas exposed to steam, volatile oil (including machine oil), or
sulfuric gas, areas exposed to high salt content such as the seaside, the
performance can be significantly reduced and the internal parts can be
damaged.
• Do not install the unit where combustible gases may leak, be produced,
fl ow, or accumulate. If combustible gas accumulates around the unit, fi re or
explosion may result.
• Do not keep food, plants, caged pets, artwork, or precision instruments in
the direct airfl ow of the indoor unit or too close to the unit, as these items
can be damaged by temperature changes or dripping water.
1.2. Before installation or relocation
Caution:
• Be extremely careful when transporting the units. Two or more persons are
needed to handle the unit, as it weighs 20 kg, 44 lbs or more. Do not grasp
the packaging bands. Wear protective gloves as you can injure your hands
on the fi ns or other parts.
• Be sure to safely dispose of the packaging materials. Packaging materials,
such as nails and other metal or wooden parts may cause stabs or other
injuries.
• Thermal insulation of the refrigerant pipe is necessary to prevent conden-
sation. If the refrigerant pipe is not properly insulated, condensation will be
formed.
• Place thermal insulation on the pipes to prevent condensation. If the drain
pipe is installed incorrectly, water leakage and damage to the ceiling, fl oor,
furniture, or other possessions may result.
1.3. Before electric work
Caution:
• Be sure to install circuit breakers. If not installed, electric shock may result.
• For the power lines, use standard cables of suffi cient capacity. Otherwise,
a short circuit, overheating, or fi re may result.
• When installing the power lines, do not apply tension to the cables.
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 12 hours before starting opera-
tion. Starting operation just after turning on the power switch can severely
damage the internal parts.
• Before starting operation, check that all panels, guards and other protective
parts are correctly installed. Rotating, hot, or high voltage parts can cause
injuries.
2. Selecting the installation location
2.1. Indoor unit
• Where airfl ow is not blocked.
• Where cool air spreads over the entire room.
• Where it is not exposed to direct sunshine.
• At a distance 1 m (3 ft) or more away from your TV and radio (to prevent picture
from being distorted or noise from being generated).
2.2. Wireless remote controller mounting (For PAR-SF9FA-E*)
• Place of mounting
• Where it is easy to operate and easily visible.
• Where children can not touch.
• Mounting
Select a position about 1.2 m (4 ft) above the fl oor, 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
to a pillar or wall and set the wireless remote controller.
• When the room humidity exceeds 80% or when the drain pipe is clogged,
water may drip from the indoor unit. Do not install the indoor unit where
such dripping can cause damage.
• When installing the unit in a hospital or communications offi ce, be prepared
for noise and electronic interference. Inverters, home appliances, high-
frequency medical equipment, and radio communications equipment can
cause the air conditioner to malfunction or breakdown. The air conditioner
may also aff ect medical equipment, disturbing medical care, and communi-
cations equipment, harming the screen display quality.
• Do not clean the air conditioner unit with water. Electric shock may result.
• Tighten all fl are nuts to specifi cation using a torque wrench. If tightened
too much, the fl are nut can break after an extended period.
• If the unit is run for long hours when the air above the ceiling is at high tem-
perature/high humidity (dew point above 26 ºC, 79 ºF), dew condensation
may be produced in the indoor unit or the ceiling materials. When operating
the units in this condition, add insulation material (10-20 mm, 25/64-25/32
inch) to the entire surface of the unit and ceiling materials to avoid dew
condensation.
• Be sure to ground the unit. If the unit is not properly grounded, electric
shock may result.
• Use circuit breakers (ground fault interrupter, isolating switch (+B fuse),
and molded case circuit breaker) with the specifi ed capacity. If the circuit
breaker capacity is larger than the specifi ed capacity, breakdown or fi re
may result.
• Do not operate the air conditioner without the air fi lter set in place. If the air
fi lter is not installed, dust may accumulate and breakdown may result.
• Do not touch any switch with wet hands. Electric shock may result.
• Do not touch the refrigerant pipes with bare hands during operation.
• After stopping operation, be sure to wait at least fi ve minutes before turn-
ing off the main power switch. Otherwise, water leakage or breakdown may
result.
• In a place as far away as possible from fl uorescent and incandescent lights (so the
infrared remote control can operate the air conditioner normally).
• Where the air fi lter can be removed and replaced easily.
Warning:
Mount the indoor unit into a ceiling strong enough to withstand the weight of
the unit.
In rooms where inverter type fl uorescent lamps are used, the signal from the
wireless remote controller may not be received.
