Dimension (2) should be at least 30 in (762 mm). The range
hood should be approximately the same size as the cook top.

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 back wall, depending on the direction of venting chosen.

REMOVING THE VENTING HOLE
(FOR EXTERIOR VENTING)
Choose the venting hole to remove for your installation type. Use
the top holes (3 & 4) for a top venting installation and the back
hole (5) for a back venting installation. See Installing the damper
section for more details.
Carefully remove the cover (3, 4 or 5) of the appropriate venting

the underside of the cabinet.
Set the range hood (A) aside on a protective surface.
Drill four pilot holes in the locations that you marked.
Screw the four long tapping screws (AA) into the pilot holes.
Do not tighten the screws all the way – leave the screw
heads about 0.28 in (7 mm) from the cabinet surface.
Lift the range hood (A) into position, feeding the power
cable and the electrical wires through the power access
opening. Allow some slack in the cable and wires so that the
appliance can be moved if servicing is ever necessary.
Position the range hood (A) so the large end (2) of the
keyhole mounting slots (1) are over the screws (AA). Then
push the range hood (A) toward the wall so the screws (AA)
are in the neck (3) of the keyhole slots. Tighten the screws
(AA). Ensure that the range hood (A) is securely fastened to
the cabinet before releasing it.
If applicable, test the damper to ensure it rotates up and
down freely.
If applicable, connect the duct work to the range hood (A).

Troubleshooting
'$1*(5 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 Solution
The range hood does not operate. 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 of the control switch is properly connected.
The range hood is very loud or 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 blade is not damaged or warped and that it is not hitting
anything or causing the range hood to vibrate. If so, replace the fan blade.
The fan seems weak. Check that the duct size used is at least 7 in (177 mm) round. The range hood
ZLOOQRWIXQFWLRQHIŵFLHQWO\ZLWKLQVXIŵFLHQWGXFWVL]H
Check that the duct is not clogged with debris and the tight mesh on the wall
FDSLIDSSOLFDEOHLVQőWUHVWULFWLQJDLUŶRZ
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 within the previously recommended distance.
Check that duct work follows all requirements. Use round metal duct work with
a uniform diameter of 7 in (177 mm). 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.
Light(s) do not work. Check to see if light bulbs are damaged. If so, replace.
Check the light bulbs to see if they are 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.
