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.

WARNING

• 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.

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.

To prevent injury to the user or other people and property damage, the following instructions

must be followed.

n Incorrect operation due to ignoring instruction will cause harm or damage. The seriousness

is classified by the following indications.

1. Electric works should be carried out according to ‘The technology requirement on the elec-

tric installation’, The wiring standard and this manual by a qualified personnel.

2.

If the installation is not complete, electric shock or fire may occur, or death or injury can be caused.

3. If the capacity of the power circuit is insufficient or its installation was not done completely,

this may cause electric shock, fire or etc..

4. If the installation was done by a user, there may be incompleteness, which may cause elec-

tric shock, fire, injury and death.

5. When operating the machine (applying power to the machine), do not carry out any electric

work and do not put hand or finger into it. This may cause electric shock, injury and death.

6. Use only UL1996 approved heater.

n Meanings of symbols used in this manual are as shown below.

WARNING

CAUTION

This symbol indicates the possibility of death or serious injury.

This symbol indicates the possibility of injury or damage.

Be sure not to do.

Be sure to follow the instruction.

WARNING

IMPORTANT !

ATTENTION

:

Toute installation, réglage, modification, entretien ou maintenance incorrect peut annuler la garantie.

Le poids de l'unité groupe compresseur-condenseur impose des procédures appropriées d'attention et de manipulation

lors des opérations de levage ou de déplacement afin d'éviter tout risque de blessures. Évitez surtout les contacts avec les bords tranchants ou pointus.

Consignes de sécurité

•

L'installation des équipements nécessite que les intervenants portent toujours des lunettes et des gants de sécurité.

•

Ne considérez jamais que l'alimentation électrique est déconnectée. Vérifiez toujours avec les appareils appropriés.

NOTE DESTINÉE AU REVENDEUR INSTALLATEUR

: Les modes d'emploi et garanties doivent être remis au client ou placés de façon

évidente à proximité de l'unité générateur d'air chaud / armoire de traitement d'air.

Lors du câblage :

Une décharge électrique peut causer des blessures graves ou un accident mortel.

Le câblage de ce système ne peut être confié qu'à un électricien qualifié et expérimenté.

•

Ne mettez pas l'appareil sous tension tant que tous les câblages et raccordements de tuyaux n'ont pas été terminés ou réalisés, puis vérifiés.

• Ce système utilise des tensions électriques élevées et dangereuses. Lors du câblage, reportez-vous soigneusement au

schéma de câblage et à ces instructions.

Tout raccordement incorrect ou mise à la terre incorrecte peut causer des accidents provoquant des blessures, voire la mort.

• La mise à la terre doit être effectuée conformément aux codes électriques locaux.

•

Branchez tous les câbles fermement. Un câblage desserré peut provoquer une surchauffe aux points de connexion avec le risque de déclenchement d'un incendie.

Lors de l'installation...

... dans un mur :

Vérifiez que le mur est suffisamment solide pour contenir le poids de l'appareil.

Il sera peut-être nécessaire de construire un cadre robuste en bois ou en métal comme complément de support.

... dans une pièce

:

Isolez de façon appropriée toute la tubulure présente dans la pièce afin de prévenir

toute "transpiration" avec le risque de voir le mur et le plancher endommagés par l'écoulement de

l'eau.

Lors des opérations d'entretien

• Avant d'ouvrir l'appareil pour des contrôles ou réparations des pièces électriques et du câblage,

mettez l'appareil hors tension (OFF) au niveau du boîtier d'alimentation principal (secteur).

• Une fois les opérations terminées, nettoyez le site et vérifiez bien qu'aucun déchet métallique ou

morceau de câblage n'ait été oublié à l'intérieur de l'appareil ayant fait l'objet de l'entretien.

AVERTISSEMENT

•

• Les informations contenues dans ce manuel s'adressent à des techniciens qualifiés habitués aux procédures de

sécurité et équipés des outils et instruments de test appropriés.

• Tout manquement à une lecture soignée et au suivi précis de toutes les instructions de ce manuel peut se traduire

par un dysfonctionnement des équipements, des dommages aux biens, des blessures et/ou accidents mortels.

Lisez cette fiche d'instructions entièrement avant d'installer le produit.

Ce système de climatisation répond strictement aux normes de sécurité et de fonctionnement. En tant que personne chargée de l'installation ou de l'entretien

de cet appareil, une part importante de votre travail d'installation ou d'entretien de ce système consiste à ce qu'il fonctionne efficacement en toute sécurité.

L'installation doit s'adapter aux codes du bâtiment local ou avec le National Electrical Code NFPA 70/ANSI C1-1993

(ouédition en vigueur), ainsi que le Code électrique canadien CSA C.22.1 Part1.
