INSTALLATION MANUAL

1. SAFETY PRECAUTIONS

1.1. IMPORTANT! 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 warning and caution notices given in this manual.

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.

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 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 wir-

ing diagram and these instructions when wiring. Improper connections and inadequate

grounding (earthing) can cause accidental injury or death.

• Ground (earth) 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.

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 drip-

ping 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 Systems)

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