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 applicable local regulations comprise 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 power pack 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, filters or in exhaust ducts.
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 indoor use only.
2. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.
4. Your power pack 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 power pack serviced.
5. The minimum power pack distance above cooktop must not be less than 24". A maximum of 30" above cooktop is recommended for best capture of cooking impurities.
6. Two installers are recommended because of the large size and weight of this unit.
7. 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.
8. 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.
9. 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.
10. To reduce the risk of fire and electrical shock, the Best models PK22 series should only be installed with their own built-in blowers, and the Best models PKEX22 Series must only be installed with Best external blower models EB6, EB9, EB12 or EB15; or Best in-line blowers models ILB3, ILB6, ILB9, ILB11. Other blowers cannot be substituted.
11. PKEX22 models used with ILB3, ILB6 or EB6 blower, must be installed over ranges rated 60,000 Btu/hr. maximum.
12. Please read specification label on product for further information and requirements.

13. This power pack is equipped with a RF receiver (optional remote control sold separately). Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this product. The remote control has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules and the Canadian ICES-003. These limits are designed to provide reasonable protection against harmful interference in a residential installation. The remote control generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

14. Reorient or relocate the receiving antenna

15. Increase the separation between the equipment and receiver
16. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected

For a PKEX22 series power pack, either an external blower or in-line blower must be used. The PKEX22 series power pack must be installed with blower models ILB3, ILB6, ILB9, ILB11, EB6, EB9, EB12 or EB15 only. Other blowers cannot be substituted (blowers sold separately.)

If installing external or in-line blower, refer to instructions packed with blower and follow steps 1 to 6, 11 to 16, 18 and up of this manual.

Plan where and how the ductwork will be installed.

A straight, short duct run will allow the power pack to perform most efficiently. Long duct runs, elbows and transitions will reduce the performance of the power pack. Use as few of them as possible. Larger ducting may be required for longer duct runs.

Install proper-sized ductwork, elbows and roof or wall cap for the type of blower you are installing. Connect metal ductwork to cap and work back towards the hood location. Use 2" metal foil duct tape to seal the joints.

The minimum power pack distance above cooktop must not be less than 24". A maximum of 30" above cooktop is recommended for best capture of cooking impurities.

Distances over 30" are at the installer and users discretion.

3. PREPARE CUSTOM HOOD

WARNING

• When building a custom hood, always follow all applicable construction codes and standards.
• Make sure the cabinet is capable of supporting its own weight and the weight of the power pack. Failure to do so may cause personal injury or damage to countertop or cooktop.

The custom hood must be constructed to fit the size and shape of the power pack. Proper structural support is required to accommodate the weight of the hood.

Start with the custom hood base, because its position will determine the height of the power pack. We recommend the base of the custom hood should be 3/4-inch thick plywood. If an optional custom hood liner will be installed, we recommend the sides and front of the custom hood to be 3/4-inch thick, assuming standard cabinet width. If the optional custom hood liner will not be installed, the custom hood side and front thickness is at the installer's discretion.

Run power cable to installation location. Stub out a 4-foot length of electrical cable below the custom hood.

17. CALIBRATE IQ BLOWER SYSTEM™ (PK22 SERIES ONLY)

After the power pack is installed and wired, engage the calibration process (our Guaranteed Performance System Technology to ensure full-rated airflow is being delivered). Prior to calibration, ensure that all filters, light bulbs and duct system are installed.

CALIBRATION PROCESS

Hold the calibration button for 3 seconds; calibration button will light up and stay on for up to 13 minutes. The blower will start and begin the calibration process. When calibration is complete, one of two things will occur:

A. The blower turns off and calibration button light stays on = Successful calibration. Press the button to turn off the LED. NOTE: The LED will also turn off if you select any blower speed on the control.
B. The blower turns off and calibration button light blinks continuously = Too much restriction in the ductwork is preventing the IQ Blower System™ from achieving the rated airflow. The blower is automatically set to maximum intensity.

NOTE: Common items that cause restrictions: restricted damper flap (backdraft damper, wall cap, roof cap), too many elbows, duct size less than 80% of hood crushed ducting.

CALIBRATION BUTTON CALIBRATION LIGHT HC0066

Three options are available if your power pack system has too much restriction:

1. Accept airflow as is. Press the calibration button to accept airflow as is. The IQ Blower System™ is now configured to its highest possible performance. The blinking calibration light goes out. NOTE: The LED will also turn off if you select any blower speed on the control.
2. Correct duct restriction, clear the original calibration data, and repeat the calibration process.

a. Correct the duct restriction.

b. Clear the original calibration data by holding calibration button for 10 seconds. The light will blink 3 times to confirm and the blower configuration will go back to default settings.

c. Repeat calibration process from the beginning.

1. Clear calibration data to reset power pack to default factory settings and achieve standard high pressure blower performance by holding calibration button for 10 seconds. The light will blink 3 times to confirm and the blower configuration will go back to default settings.

18. LIGHT BULBS

This power pack requires shielded halogen lamps (120 V, 50 W, PAR16 with GU10 base, 2 for 30" and 39" width power packs, 3 for 45" width power pack), included.

NOTE: Before using lamps, remove shipping tape on them (if present).

WARNING

Do not touch lamps during or soon after operation. Burns may occur. In order to prevent the risk of personal injury, only install shielded halogen lamps. Also, never install a cool beam, a dichroic lamp, a lamp not suitable for use in recessed luminaires or identified for use in enclosed fixtures.

1. Install the lamps by placing the bulb leads into their grooves in the socket.
2. Gently push upwards and turn clockwise until secure.

To remove lamps, gently push upwards and turn counterclockwise to disengage bulb leads from their grooves.

NOTE: If need be, use a rubber dishwashing glove to add grip when removing the bulb; or use suction cup tool available from Best to ease removal of the bulbs. Contact Best Customer Service at 1-800-558-1711 to order suction cup tool, part number 99526707.

19. USE AND CARE

Hybrid Baffle Filters

The hybrid baffle filters should be cleaned frequently. Use a warm detergent solution. Wash more often if your cooking style generates greater grease — like frying foods or wok cooking.

Remove hybrid baffle filters by pushing them towards the back of power pack and rotating filters downward. Baffle filters are dishwasher safe. Allow filters to dry completely before reinstalling them in the power pack.

Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergent or as a result of local water conditions — but this will not affect filter performance. This discoloration is not covered by the warranty.

Internal Blowers Cleaning

Remove filters in order to access blowers. Vacuum blowers to clean. Do not immerse in water.

Power Pack Cleaning

Stainless steel cleaning:

Do:Regularly wash with clean cloth or rag soaked with warm water and mild soap or liquid dish detergent.Always clean in the direction of original polish lines.Always rinse well with clear water (2 or 3 times) after cleaning.Wipe dry completely.You may also use a specialized household stainless steel cleaner.

Don't:Use any steel or stainless steel wool or any other scrapers to remove stubborn dirt.Use any harsh or abrasive cleansers.Allow dirt to accumulate.Let plaster dust or any other construction residues reach the power pack. During construction/renovation, cover the power pack to make sure no dust sticks to stainless steel surface.

Avoid when choosing a detergent:

• Any cleaners that contain bleach will attack stainless steel.
• Any products containing: chloride, fluoride, iodide, bromide will deteriorate surfaces rapidly.
• Any combustible products used for cleaning such as acetone, alcohol, ether, benzol, etc., are highly explosive and should never be used close to a range.

20. OPERATION
