Report damage and missing parts immediately. Do not dispose of packaging before you are satisfied with your new range hood.

• Before installation, measure all distances to ensure the proper position of the range hood (A).
  – The distance (1) from the cooking surface to the range hood must be at least 458 mm (18 in). For the best performance, do not install the range hood more than 710 mm (28 in) above the cooking surface.
  – Dimension (2) should be at least 762 mm (30 in). The range hood should be approximately the same size as the cook top.

• If the bottom of the cabinet (3) above the location where the range hood is to be installed is recessed, attach appropriately sized wood filler strips (4) on each side using wood screws.

• Screws are provided to secure the range hood to most types of cabinets, but consult a qualified installer to verify that the supplied screws are suitable for your cabinets.

• Put a thick, protective covering over your counter, cooktop, or range to protect it from damage and dirt during installation. Remove any hazardous objects around the area.

Always wear safety goggles and gloves during installation.

VENTING OPTIONS:
a. Determine if your existing venting system is top venting or back venting, and ensure that the openings in the cabinet or wall for the damper and for power access are in appropriate locations and are of appropriate sizes, as per Fig. 3 if it is top venting or Fig. 4 if it is back venting.
For top venting option (Fig. 3), if you are using the round adapter, the opening should be A and B only. If you are using the rectangular damper, opening should be B and C only.
b. If this is a new installation, choose the venting method that suits your needs. Cut out openings for the damper and for power access in the cabinet bottom or exterior wall, depending on the direction of venting chosen. FOLLOW THESE GUIDELINES WHEN INSTALLING DUCT WORK

• Your venting system must vent to the outdoors either horizontally through the back wall (13) or vertically through the roof (14) (refer to Fig. 5/Fig. 6/Fig. 7).
• Use round metal duct work with a uniform diameter of 177 mm (7 in). The total duct run in the venting system should not be more than 10.7 m (35 Fig).
• Calculate the total effective length of the duct work by adding the equivalent lengths in the table shown (Fig. 9). For each fittingused add the length of the equivalent straight duct used in the system.
• Fasten all connections between pieces of duct with sheet metal screws and tape all joints with certified duct tape.
• If you must turn the path of the duct work using elbows, keep the number of elbows to a minimum for effective performance anduse no more than three 90° elbows. Ensure that there is a minimum of 458 mm (18 in) of straight vent between each elbow. Elbowas far away from the range hood’s exhaust opening as possible.
• Cap the exterior of the duct with a wall cap (15) or roof cap (16). Never use 102 mm (4 in) laundry-type wall caps. Use caulking toseal exterior wall or roof opening around the cap.
• The venting system must have a damper. If the roof or wall cap has a damper, do not use the damper supplied with the range hood.

For inside venting system (air does not exhaust to outdoors) (Fig. 8):
Please refer to the Installation section. The cover on the top plate will be removed and air will be exhausted through the charcoal filter and out from 17.

CARE AND CLEANING

RANGEHOOD
The range hood should be cleaned (regularly internally and externally) to preserve its appearance and performance.

DO:

• Always clean in the direction of the grain (original polish lines).
• Clean the range hood periodically with hot, soapy water and a clean cotton cloth.
• Always rinse well with clean water two or three times afterer cleaning. Wipe completely dry with a soft non-abrasive cloth.
• Afterer cleaning, you may polish with a non-abrasive stainless steel polish or cleaner. Always rub lightly and with the grain.
• Ensure that the venting system is free of debris, if you have one.

DO NOT:

• Do not use corrosive or abrasive detergents, steel wool, or scouring pads. These will scratch and damage the stainless steel surface.
• Do not use any products containing chloride, fluoride, iodide, or bromide on this product, as they will deteriorate the surface rapidly.
• Do not allow cleaning compounds, salt solutions, disinfectants, or bleaches to remain in contact with the product for extended periods of time.
• Do not allow any deposits to remain for long periods of time on the range hood. Rinse with water immediately and wipe dry with a clean cloth.
• Do not let plaster dust or any other construction residue enter the hood. During construction or renovation, cover the hood.
• Combustible products used for cleaning such as acetone, alcohol, ether, or benzol are highly explosive and should never be used close to a range or stove.

Failure to maintain basic standards of care nad cleaning of the range hood will increase the risk of fire.

FILTER
The filter fitted by the factory is intended to filter out residue and grease from cooking. Yo do not need to replace them on a regular basis, but you should keep them clean.

DO:

• Clean the filter once a month using non-abrasive detergents, either by hand or in the dishwasher. When using a dishwasher, set the dishwasher to a low temperature and a short cycle setting. The filter may become discoloured in a dishwasher, but this does not affect its performance.
• Allow filters to completely dry before re-installing them in the rangehood.

DO NOT:

• Do not allow oil to accumulate over more than 80% of the filter surface. Oil accumulations may drip oil on the range.
• Do not wash charcoal filter. The charcoal filter should be replaced when it is covered in grease and has reached its maximum absorbancy.

TROUBLESHOOTING

Turn off the power circuit breaker or the power switch on the junction box before performing maintenance.
Touching circuitry inside the range hood while it is energized may result in serious injury or death.

electrical wiring are properly connected.
• Check that the power is turned on at the junction box or circuit breaker.
• Check that the wiring between the switch control and the control board are connected properly.
The range hood vibrates when the fan is operating.| • Check that the range hood has been secured properly. Tighten into position, if necessary.
• Check that the motor is secured in place. If not, then tighten the motor in place.
• Check that the fan is not damaged. If so, replace the fan.
The fans seem weak.| • Check that the duct size used is at least 177 mm (7 in) round. The range hood will not function e ciently with insu cient duct size.
• Check that the duct is not clogged with debris and the tight mesh on the wall cap, if applicable, isn’t restricting air flow.
• Check that the damper unit is opening properly.
• Check that no birds or animals have nested in the duct.
The lights work, but the fan is not spinning, is stuck, or is rattling.| • The thermal protection system detects if the motor is too hot to operate and shuts the motor down. In this case, the motor will function properly after the thermal protection system cools down (after approximately 10 min).
• Check that the fan isn’t jammed or scraping the bottom.
• If nothing else works, the motor may be defective or seized. If so, replace the motor.
The range hood is not venting properly.| • Check that no birds or animals have nested in the duct.
• Check that the distance between the cooktop and the bottom of the range hood is between 458 mm (18 in) and 710 mm (28 in).
• Check that duct work follows all requirements. Use round metal duct work with a uniform diameter of 177 mm (7 in). The length of duct work must not exceed 35 ft (10.7 m). Reduce the length of duct work and the number of elbows if necessary. Ensure that all joints are properly connected, sealed, and taped.
• Check that the duct does not open against the wind.
• Ensure that the power is on high speed for heavy cooking.
• Close all windows nearest to the range hood to eliminate sudden air gusts.
• To enhance the performance of the range hood, open slightly a window on the opposite side of the house where the range hood vents outdoors.
A light does not work.| • Check to see if light bulb is burnt. If so, replace.
• Check the light bulb to see if it is loose. If so, tighten.
• Remove the problem bulb and insert one you know is working. If the properly functioning light does not come on, the problem may be the light assembly. Have the light assembly serviced or replaced.
