IMPORTANT!

Please Read Before Starting

This air conditioning system meets strict safety and oper-

ating standards. As the installer or service person, it is an

important part of your job to install or service the system

so it operates safely and efficiently.

For safe installation and trouble-free operation, you

must:

●

Carefully read this instruction booklet before beginning.

●

Follow each installation or repair step exactly as

shown.

●

Observe all local, state, and national electrical codes.

●

Pay close attention to all warning and caution notices

given in this manual.

This symbol refers to a haz-

ard or 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.

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

failure to follow the instructions in this document.

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 unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause

overheating at connection points and a possible fire

hazard.

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 pre-

vents 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

• 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

• 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 refriger-

ant 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.

Insulation of Refrigerant Tubing

Because capillary tubing is used in the outdoor unit, both the

wide and narrow tubes of this air conditioner become cold. To

prevent heat loss and wet floors due to dripping of condensa-

tion, both tubes must be well insulated with a proper insu-

lation material. The thickness of the insulation should be a

minimum 8 mm.

IMPORTANT

CAUTION

After a tube has been insulated,

never try to bend it into a narrow

curve because it can cause the

tube to break or crack.

AVOID:

●

direct sunlight.

●

nearby heat sources that may affect performance of

the unit.

●

areas where leakage of flammable gas may be

expected.

●

places where large amounts of oil mist exist.

DO:

●

select an appropriate position from which every cor-

ner of the room can be uniformly cooled. (High on a

wall is best.)

●

select a location that will hold the weight of the unit.

●

select a location where tubing and drain hose have

the shortest run to the outside. (Fig. 1)

●

allow room for operation and maintenance as well as

unrestricted air flow around the unit. (Fig. 2)

●

install the unit within the maximum elevation differ-

ence (H) above or below the outdoor unit and within

a total tubing length (L) from the outdoor unit as

detailed in Table 1 and Fig. 3.
