IMPORTANT! 
Please Read Before Starting

This air conditioning system meets strict safety and operat-
ing 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

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.

• Install a protective 

leakage breaker 

depending on the

installation location (especially a damp or humid loca-
tion). 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 fin-
gers. 

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

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 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.
