WARNING WARNING

- 2 -

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the

manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service panel and lock service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

3. Installation work and electrical wiring must be done by qualified personnel in accordance with all applicable codes and standards, including fire-rated construction codes and standards.

4. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer’s guidelines and safety standards such as those published by the National Fire Protection Association (NFPA) and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) and the local code authorities.

5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

6. Ducted fans must always be vented to the outdoors.

7. Do not use this unit with any solid-state speed control device.

8. To reduce the risk of fire, use only metal ductwork.

9. This unit must be grounded.

10. When the federal, provincial or state legislation

comprises more restrictive installation and/or certification requirements, the aforementioned requirements prevail on those of this document and the installer agrees to conform to these at his own expenses.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

a) Never leave surface units unattended at high

settings. Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly on low or medium settings.

b) Always turn hood ON when cooking at high heat or

when flambeing food (i. e.: Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).

c) Clean ventilating fans frequently. Grease should

not be allowed to accumulate on fan or filter.

d) Use proper pan size. Always use cookware

appropriate for the size of the surface element.

TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING*:

1. SMOTHER FLAMES with a close-fitting lid,

cookie sheet or metal tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS. IF THE FLAMES DO NOT GO OUT IMMEDIATELY, EVACUATE AND CALL THE FIRE DEPARTMENT.

2. NEVER PICK UP A FLAMING PAN—You may be burned.

3. DO NOT USE WATER, including wet dishcloths or towels—This could cause a violent steam explosion.

4. Use an extinguisher ONLY if: A. You own a Class ABC extinguisher and you

know how to operate it.

B. The fire is small and contained in the area

where it started.

C. The fire department has been called. D. You can fight the fire with your back to an exit.

* Based on “Kitchen Fire Safety Tips” published by NFPA.

CAUTION

1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.

2. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.

3. Your insert motor has a thermal overload which will automatically shut off the motor if it becomes overheated. The motor will restart when it cools down. If the motor continues to shut off and restart, have the insert serviced.

4. The minimum hood distance above cooktop must not be less than 24”. A maximum of 30” above cooktop is highly recommended for best capture of cooking impurities.

5. Two installers are recommended because of the large size and weight of this unit.

6. To reduce the risk of fire and to properly exhaust air, be sure to duct air outside—Do not exhaust air into spaces within walls or ceiling or into attics, crawl space or garage.

7. This product is equipped with a thermostat which may start blower automatically. To reduce the risk of injury and to prevent power from being switched on accidentally, switch power off at service panel and lock or tag service panel.

8. Because of the high exhausting capacity of this unit, you should make sure enough air is entering the house to replace exhausted air by opening a window close to or in the kitchen.

9. To reduce the risk of fire and electrical shock, the Best models CP35 & CP37 Series should only be installed with their own built-in blowers. Other blowers cannot be substituted.

10. Please read specification label on product for further information and requirements.

2. INSTALL DUCTWORK AND ELECTRICAL WIRING

Plan where and how the ductwork will be installed. Access to the top of the hood is preferred for connection of ductwork.

Install proper-sized ductwork, elbows and roof or wall cap for the type of blower you are installing. If installing CP35 power pack, use 8” round ductwork and if installing CP37 power pack, use 10” round ductwork. Use 2” metal duct tape to seal duct joints.

The minimum hood distance above cooktop must not be less than 24”. A maximum of 30” above cooktop is highly recommended for best capture of cooking impurities.

Distances over 30” are at the installer and users discretion. Run 3-wire power supply cable to installation location. Its length should extend at least

4 feet below the bottom of the custom hood.

Since the CP35 and CP37 power pack mounting holes are located in front and rear sides (see illustration beside), plan to install wood frame at front and sides for support.

The CP35 and CP37 power pack is supported by the custom hood internal framework with screws provided in parts bag.

WARNING

The framework must be positively secured to wall studs or other wooden framework behind the drywall. Make sure it is capable of supporting its own weight and the weight of the CP35 or CP37. Failure to do so may cause personal injury or damage to countertop or cooktop.
