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 sale/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

• During installation, connect before the refrigerant system and

then the wiring one; proceed in the reverse orden when removing
the units.

When wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A QUALIFIED,
EXPERIENCED ELECTRICIANS SHOULD ATTEMPT
TO WIRE THIS SYSTEM.

• Do not supply power to the unit until all wiring and tubing are

completed or reconnected and checked, to ensure the grounding.

• 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 and death

.

Ground the unit 

following local electrical codes.

• The Yellow/Green wire cannot be used for any connection

different from the ground connection.

• Connect all wiring tightly. Loose wiring may cause overheating

at connection points and a possible fire hazard.

• Do not allow wiring to touch the refrigerant tubing, compressor,

or any moving parts of the fan.

• Do not use multi-core cable when wiring the power supply and

control lines. Use separate cables for each type of line.

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 aluminium 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-weight.
It may be necessary to build a strong wooden or metal frame to
provide added support.

... In a room

Properly insulate any tubing run inside a room to prevent
"sweating", which can cause dripping and water damage to walls
and floors.

... In moist or uneven locations

Use a raised concrete base to provide a solid level foundation for
the outdoor unit.
This prevents damage and abnormal vibrations.

... In area with strong 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

• 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;  screw by hand and
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 narrow tube for
liquid, wide tube for gas.

When servicing

• Turn the power OFF at the main power board  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 the work, remembering to check that no

metal scraps or bits of wiring have been left inside the unit being
serviced.

• Ventilate the room during the installation or testng the refrigeration

system; make sure that, after the installation, no gas leaks are
present, because this could produce toxic gas and dangerous
if in contact with flames or heat-sources.
