Best UCB3I Series

WARNINGTO 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 d outdoors.
  7. To reduce the risk of fire or electric shock, do not use this unit with any additional solid-state speed control device.
  8. To reduce the risk of fire, use only metal ductwork.
  9. This unit must be grounded.
  10. All tempered glass can experience spontaneous breakage. If broken, tempered glass falls out of it’s opening in interlocking clumps. Tempered glass can, on occasion, break into large shards rather than the classic tiny piece pattern.
  11. 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 expense.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

  1. 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.
  2. Always turn hood ON when cooking at high heat or when flambeing food (i.e.: Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
  3. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan, filters or in exhaust ducts.
  4. Use proper pan size. Always use cookware appropriate for the size of the surface element.

WARNINGTO 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:
    1. You own a Class ABC extinguisher and you know how to operate it.
    2. The fire is small and contained in the area where it started.
    3. The fire department has been called.
    4. 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 hood motor has a thermal overload which will automatically shut off the motors if it overheats. The motors will restart when cooled down. If the motor(s) continues to shut off and restart, have the hood serviced.
  5. 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. For a gas range, the bottom of the hood MUST NOT BE LESS than 30” above cooktop.
  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. 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. Use with approved cord-connection kit only.
  10. Please read specification label on product for further information and requirements.

INSTALL DUCTWORK

Plan where and how the ductwork will be installed.The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow. Refer to the table at the bottom of this page to help you plan the most efficient installation.Install wall or roof cap; once done, ensure there is no leak in house insulation. Connect metal ductwork to cap and work back towards the hood location. If 6” round ducts are installed, use a 3¼” x 10” to 6” transition positioned, if possible, 18” away from the adapter/damper. Use 2” metal foil duct tape to seal the joints.We recommend to install the hood at a minimum distance of 24” from an electric range and of 30” from a gas range.Distances over 30” are at the installer and users discretion.

CARE

HYBRID FILTERS AND BOTTOM PANEL

The hybrid filters and the bottom panel should be cleaned frequently. Use a warm detergent solution.Remove hybrid filters by pushing them towards the back of hood and rotating downward.Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the filters may occur if using phosphate detergents, or as a result of local water conditions — this will not affect filter performance. This discoloration is not covered by the warranty. To minimize or prevent discoloration, hand wash filters using a mild detergent.

STAINLESS STEEL

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 hood. During construction/renovation, cover the hood to make sure no dust sticks to stainless steel surfaces.
GLASS PANEL

Hot water with mild soap or glass cleaner is all that is usually needed.When using mild soap, rinse with clear water. Wipe dry with a clean, soft cloth to avoid water marks.

Avoid when choosing a detergent:

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

OPERATION

Always turn your hood on before you begin cooking to establish an air flow in the kitchen. Let the blower run for a few minutes to clear the air after you turn off the range.

CAUTIONAfter a power failure or during the range hood power up, a 5-second booting sequence is executed. Wait for the control backlighting to turn off before use.
