IMPORTANT!

CAUTION : Improper installation, adjustment, alteration, service or maintenance can void the warranty.

The weight of the condensing unit requires caution and proper handling procedures when lifting

or moving to avoid personal injury. Use care to avoid contact with sharp or pointed edges.

Safety Precautions

• Always wear safety eye wear and work gloves when installing equipment.

• Never assume electrical power is disconnected. Check with meter and equipment.

NOTE TO INSTALLING DEALER : The Owners Instructions and Warranty are to be given to the owner

or prominently displayed near the indoor Furnace/Air Handler Unit.

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.

• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.

When installing...

... in a wall: Make sure the 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 wall and floors.

When servicing

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

electrical parts and wiring.

• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have

been left inside the unit being serviced.

Please read this instruction sheet completely before installing the product.

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.

• Installation must adapt with local building codes or with the Nation al Electrical code NFPA 70/ANSI C1-1993 (or

current edition ) along with Canadian Electrical Code Part1 CSA C.22.1

• The information contained in the manual is intended for use by a qualified service technician familiar with safety

procedures and equipped with the proper tools and test instruments.

• Failure to carefully read and follow all instructions in this manual can result in equipment malfunction, property

damage, personal injury and/or death.
