IMPORTANT!

DANGER:

WARNING:

CAUTION:

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 danger, warning, and caution
notices given in this manual

This symbol warns of an imme­diate hazard which will result in
severe personal injury or death.

This symbol refers to a hazard or
unsafe practice which can result
in severe personal injury or
death.

• 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.

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.

…In an Area with High Winds

Securely anchor unit down with bolts and 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

• Keep all tubing runs as short as possible.

• 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.

NOTE:

Depending on the system type, liquid and gas lines may be
either narrow or wide. Therefore, to avoid confusion the
refrigerant tubing for your particular model is specified as
either “narrow” or “wide” rather than as “liquid” or “gas.”

When Servicing

• Turn the power OFF at the main power box (mains)
before opening the unit to check or repair electrical parts.

• Keep your fingers and clothing away from any moving
parts.

• Clean up the site after you finish, remembering to check
that no scraps or bits of wiring have been left inside the
unit being serviced.
