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 accidentaly 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.

Important

CAUTION

When Installing

……………………………………………………………………

…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 Sys-
tems)
Install the outdoor unit on a raised platform that is higher
than drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

……………………………………………………………………

• Ventilate the room well, in the event that refrigerant gas

leaks during the installation. Be careful not to allow
contact of the refrigerant gas with a flame as this will
cause the generation of poisonous gas.

• 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 and wiring.

• Keep your fingers and clothing away from any moving

parts.

• Clean up the site when installation is finished. Check

that no metal scraps or bits of wiring have been left
inside the unit.

CAUTION

• Ventilate any enclosed areas when installing or testing

the refrigeration system. Contact of refrigerant gas with
fire or heat can produce poisonous gas.

• Confirm after installation that no refrigerant gas is

leaking. If the gas comes in contact with a burning
stove, gas water heater, electric room heater or other
heat source, it can cause the generation of poisonous
gas.
