1.2. Special precautions

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A

QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYS-

TEM.

 Do not supply poZer to the unit until all Ziring and tubing are completed or reconnected

and checNed.

 Highly dangerous electrical voltages are used in this system. Carefully refer to the Zir-

ing diagram and these instructions Zhen Ziring. Improper connections and inadeTuate

earthing (grounding) can cause accidental injury or death.

 Earth (Ground) the unit folloZing local electrical codes.

 Connect all Ziring tightly. Loose Ziring may cause overheating at connection points and

a possible ¿re ha]ard.

When Transporting

Be careful Zhen picNing up and moving the indoor and outdoor units. Get a partner to

help, and bend your Nnees Zhen lifting to reduce strain on your bacN. Sharp edges or thin

aluminum ¿ns on the air conditioner can cut your ¿ngers.

When Installing...

...In a Ceiling or Wall

MaNe sure the ceiling/Zall is strong enough to hold the unit¶s Zeight. It may be necessary

to construct a strong Zood or metal frame to provide added support.

...In a Room

Properly insulate any tubing run inside a room to prevent ³sZeating´ that can cause drip-

ping and Zater damage to Zalls and Àoors.

...In an Area with High Winds

Securely anchor the outdoor unit doZn Zith bolts and a metal frame.

Provide a suitable air bafÀe.

...In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snoZ.

When Connecting Refrigerant Tubing

 Keep all tubing runs as short as possible.

 Use the Àare method for connecting tubing.

 Apply refrigerant lubricant to the matching surfaces of the Àare and union tubes before

connecting them, then tighten the nut Zith a torTue Zrench for a leaN-free connection.

 ChecN carefully for leaNs before opening the refrigerant valves.

When Servicing

 Turn the poZer OFF at the main circuit breaNer panel before opening the unit to checN

or repair electrical parts and Ziring.

 Keep your ¿ngers and clothing aZay from any moving parts.

 Clean up the site after you ¿nish, remembering to checN that no metal scraps or bits of

Ziring have been left inside the unit being serviced.

 After installation, e[plain correct operation to the customer, using the operating manual.

WARNING

Never touch electrical components immediately after the poZer supply has been turned

off. Electric shocN may occur. After turning off the poZer, alZays Zait 5 minutes before

touching electrical components.

If refrigerant leaNs Zhile ZorN is being carried out, ventilate the area. If the refrigerant

comes in contact Zith a Àame, it produces a to[ic gas.

CAUTION

Do not attempt to install the air conditioner or a part of the air conditioner by yourself.

This unit must be installed by Tuali¿ed personnel Zith a capacity certi¿cate for handling

refrigerant Àuids. Refer to regulation and laZs in use on installation place.

This unit is part of a set constituting an air conditioner. It must not be installed alone or

Zith a device non-authori]ed by the manufacturer.

AlZays use a separate poZer supply line protected by a circuit breaNer operating on all

Zires Zith a distance betZeen contact of 1/8 in. (3 mm) for this unit.

The unit must be correctly earthed (grounded) and the supply line must be equipped

Zith a differential breaNer in order to protect the persons.

The units are not e[plosion proof and therefore should not be installed in e[plosive

atmosphere.

When moving, consult authorized service personnel for disconnection and installation

of the unit.

Do not place any other electrical products or household belongings under indoor unit or
