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 war ning 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 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 over-

heating 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 (for Heat Pump-type Systems)

•

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.

•Do not install only a single indoor unit.

1. General

This booklet briefly outlines where and how to install the air conditioning system. Please read over the entire set of instructions for the indoor and outdoor units and make sure all accessory parts listed are with the system before beginning. If the electric wiring diagram does not appear in this manual, please check for the diagram on the indoor unit.

1-3. Optional Copper Tubing Kit

Copper tubing for connecting the outdoor unit to the indoor unit is available in kits which contain the narrow and wide tubing, fittings and insulation. Consult your nearest sales outlet or air conditioning workshop.

1-4. Type of Copper Tube and Insulation Material

If you wish to purchase these materials separately from a local source, you will need:

1. Deoxidized annealed copper tube for refrigerant tubing as detailed in Table 2.

Cut each tube to the appropriate lengths +30 cm to 40 cm to dampen vibration between units.

Tabl e 2

2. Foamed polyethylene insulation for the specified copper tubes as required to precise length of tubing. Wall thickness of the insulation should be not less than 8 mm.

3. Use insulated copper wire for field wiring. Wire size varies with the total length of wiring. Refer to 5. Wiring Instructions for details.

CAUTION

Check local electrical codes and regulations before obtaining wire. Also, check any specified instructions or limitations.

2-1. Indoor Unit

AVOID:

! direct sunlight.

! nearby heat sources that may affect performance of the

unit.

! areas where leakage of flammable gas may be expected.

! placing or allowing any obstructions near the Air

Conditioner inlet or outlet.

! installing in rooms that contain instant-on (rapid-start)

fluorescent lamps. (These may prevent the Air Conditioner from receiving signals.)

! places where large amounts of oil mist exist.

! installing in locations where there are devices that

generate high-frequency emissions.

DO:

! select an appropriate position from which every corner 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 difference

(H1, H2, H3, H4) above or below the outdoor unit and within a total tubing length (L1+L2, L1+L2+L3, L1+L2+L3+L4) from the outdoor unit as detailed in Ta b le 3 a n d F i g . 3 a .
