WARNING

CAUTION

If Necessary, Get Help

These instructions are all you need for most installation
sites and maintenance conditions. If you require help for
a special problem, contact our sales/service outlet or
your certified dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for
improper installation or maintenance service, including

SPECIAL PRECAUTIONS

unsafe practice which can result
in severe personal injury or death.

This symbol refers to a hazard
or unsafe practice which can
result in personal injury or
product or property damage.

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 (for Heat Pump-type Systems)

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

WARNING

•

Do not supply power to the unit until all wiring and tubing
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 unit following local electrical codes.

•

Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.

When Wiring

ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM.

•

Turn the power off at 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

CAUTION

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.

be used to sense the room temperature. The indoor unit sensor is usually used.

If you wish the remote controller to sense the room temperature, press the SENSOR button with a ballpoint pen or tool with
a small tip. (Refer to Fig. 9 on page 4 to locate the SENSOR button.)

I How to install the remote controller

• The remote controller is set to “Cool/Dry/Heat model” at
the time of shipment from the factory. If the purchased air
conditioner is a COOL/DRY model, follow the instructions
on the label and change the switch on the reverse side of
the remote controller unit to “Cool/Dry model”. (Fig. 1)

• The remote controller is also set to “Single” at the time of
shipment from the factory. For multiple use, set the
switch on the reverse side of the remote controller unit to
“Multi”. (Fig. 1)

• After all work is completed, if any switches have been
changed, then be sure to press the ACL (Reset) button.
