Important!

Please Read Before Starting

This air conditioning system meets strict safety and

operating 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 hazard 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

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.

WARNING

CAUTION

WARNING

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

• 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

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.

4. REFRIGERANT FLOW DIAGRAM

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

condensation, both tubes must be well insulated with a

proper insulation material. The thickness of the insulation

should be a min. 8 mm.

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.

7-1. Installation Site Selection

To prevent abnormal heat

generation and the possibility

of fire, don’t place obstacles,

enclosures and grills in front

of or surrounding the air

conditioner in a way that may

block air flow.

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

corner of the room can be uniformly air-conditioned.

(High on a wall is best)

●

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

●

select a location where tubing and drain pipe have the

shortest run to the outside.

●

allow room for operation and maintenance as well as

unrestricted air flow around the unit. (Fig. 1)

●

install the unit within the maximum elevation

difference (H) above or below the outdoor unit and

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