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.

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.

7-1. Installation Site Selection

7-1-1. Indoor Unit

AVOID:

● direct sunlight.

● nearby heat sources that may affect performance of

the unit.

● areas where leakage of flammable gas may be

expected.

● 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.

● allow room for operation and maintenance as well as

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

● install the unit within the maximum elevation differ-

ence (H) above the outdoor unit and within a total
tubing length (L) from the outdoor unit as detailed in
Table 1 and Fig. 2.

7-1-2. Outdoor Unit

AVOID:

● heat sources, exhaust fans, etc. (Fig. 4)

● damp, humid or uneven locations.

DO:

● choose a place as cool as possible.

● choose a place that is well ventilated.

● allow enough room around the unit for air intake/

exhaust and possible maintenance. (Fig. 5a)

NO

Fig. 4

CAUTION

● Install the outdoor unit above snowfall line.

● Do not place objects on or sit on the outdoor

unit. Also, never block the air intake/outlet or
exhaust. Distortion of the outdoor unit or
incomplete combustion may result.

● Touching the air exhaust can cause a burn.

Take special care for children not to touch it.

● Do not introduce foreign matter into the air

intake/outlet or exhaust. Do not insert point­ed objects, such as sticks.

● When the ambient temperature is dropping, a

white cloud or fog may be seen blowing from
the unit. This does not indicate a problem.

● The distance between any building opening*

and the exhaust must be 24 in. (60 cm) or
more.

● Locate the outdoor unit away from windows

to avoid possible entry of exhaust gases into
the building. Pay special attention to the win­dows of a neighboring house or building.

● If there is a window within 24 in. (60 cm) of

the exhaust, make sure it is not located
