SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM.
•Do not supply power to the unit until all wiring and tub-
ing are completed or reconnected and checked.
•Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and
these instructions when wiring. Improper connections
and inadequate grounding can cause accidental
injury or death.
•Ground the unitfollowing local electrical codes.
•Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.
•Install a protective leakage breaker depending on the
installation location (especially a damp or humid location). If a leakage breaker is not installed, electric
shock can occur.
When Transporting
Be careful when picking up and moving the indoor and
outdoor units. Get a partner to help, and bend your knees
when lifting to reduce strain on your back. Sharp edges or
thin aluminum fins on the air conditioner can cut your fingers.
When Installing…
…In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide
a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a
metal frame. Provide a suitable air baffle.
…In a Snowy Area
•
Position the outdoor unit in a protected location
where snow will not blow into it.
• Install the outdoor unit on a raised platform that is
higher than drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
•Use the flare method for connecting tubing.
•Apply refrigerant lubricant to the matching surfaces of
the flare and union tubes before connecting them, then
tighten the nut with a torque wrench for a leak-free
connection.
•Check carefully for leaks before starting the test run.
When Servicing
•Turn the power OFFat the main power box (mains)
before opening the unit to check or repair electrical
parts and wiring.
•Keep your fingers and clothing away from any moving
parts.
•Clean up the site after you finish, remembering to
check that no metal scraps or bits of wiring have been
left inside the unit being serviced.
Others
•Ventilate any enclosed areas when installing or testing
the refrigeration system. Escaped refrigerant gas, on
contact with fire or heat, can produce dangerously
toxic gas.
•Confirm upon completing installation that no refrigerant
gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other
heat source, it can produce dangerously toxic gas.

3. Install Indoor Unit
3-1. Install the Rear Panel
(1) Install the rear panel horizontally using a car-
penter’s level or inclinometer. Since the unit
was designed for water drainage to either the
left or right direction, depending on the outlet
side you require provide a slight downward gradient to ensure adequate drainage of the water
pan in the correct direction. (Fig. 11)
(2) Fix the rear panel to the wall using screws
required for the wall type. Use plaster board fasteners / toggle bolts for hollow walls.
(3) Be sure to affix the rear panel securely enough to
hold the weight on an adult (at least 60 kg), with
attachment screws spaced to evenly divide the
weight of the unit.
3-2. Install the Tubing Hole
(1) Determine which side of the unit you should make
the hole for tubing and wiring. (Fig. 12)
(2) Make the tubing hole (ø65 mm) in the wall at a
slight downward slant to the outdoor side. (Fig. 13)
Before making the hole, check carefully that no studs
or pipes are directly run behind the spot to be cut.
The above precautions are also applicable if tubing
goes through the wall in any other location.
(3) Insert a PVC pipe in the hole to prevent the con-
nection piping and wiring from being damaged
when passing through the hole.
3-3. Install the Drain Hose
(1) The drain hose must be angled at a downward
slant for smooth, unimpeded drainage.
(2) Supply adequate support for the hose, and do not
pull on it or permit bends or water traps to occur.
The outlet end must not be immersed in water or
otherwise blocked. (Fig. 14)
(3) When extending the drain hose inside a room,
cover it with adequate insulation to prevent condensation and dripping. This is important to avoid
damage to walls, floors, or room furnishings.
