PRE-INSTALLATION
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 ).
· 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.

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 a er cleaning. Wipe
completely dry with a so non-abrasive cloth.
· A er 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.
PROBLEM
The range hood does not operate. The range hood vibrates when the fan is
operating. The fans seem weak. The lights work, but the fan is not spinning,
is stuck, or is rattling. The range hood is not venting properly.
A light does not work.
SOLUTION
· Check that the power supply cable and all 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.
· 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.
· Check that the duct size used is at least 177 mm (7 in) round. The range
hood will not function efficiently with insufficient 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 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 a er the
thermal protection system cools down (a er 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.
· 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 (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.
· 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.
