SER VICING

NOTE: BE SURE ELECTRICAL POWER IS
OFF BEFORE SERVICING THE UNIT.

It may be necessary to remove the downdraft blower
system from the cabinet in order to service components
such as the blower motor or air vent mechanism.

Disconnect power to the cooktop and remove it first.
Reverse the steps in the Install the Downdraft section
to remove the downdraft from the cabinet.

Service parts are available from your local GE
distributor or from a GE Service and Parts Center.

CAUTION: Be careful when raising or lowering
the downdraft. Be sure pots, pot handles and other
objects are clear of the downdraft cover and cannot
be struck or tipped by the downdraft being raised.

• To avoid injury, make sure there are no fingers
around the downdraft cover when it is lowered.

• Keep hands and fingers away from all
downdraft parts.

USING YOUR DOWNDRAFT VENT SYSTEM

Controls

Turn the downdraft blower
ON by pressing down on
the activating switch. The
air vent will rise.

The blower can be ON or
OFF and its speed can be
adjusted with the recessed
knob on the right side of
the air vent.

Turn the downdraft
blower OFF by pressing
the activating switch
again. The air vent will
go down and the blower

Safety Instructions Servicing Using Vent System Cooking Tips

Knob

COOKING TIPS

• The high capacity performance of this downdraft

system can increase the cooking times for some foods.
It may take longer to reach high cooking temperatures
if the downdraft is turned on to high right away.
Adjust the fan speed for best cooking results.

For best results when heating oil for deep frying or
when boiling water, use the front surface units or wait
until the water is boiling or the oil is at frying
temperatures before turning on the downdraft.

• The downdraft may not completely capture all the

steam from pans on the front burners.

Canning

When canning foods in a water-bath canner, a gentle
but steady boil must be maintained continuously for
the required time. When canning foods in a pressure
canner, the pressure must be maintained continuously
for the required time.

Use of the blower at a high speed when canning may
reduce the temperature enough to stop boiling. While
canning, we recommend using the downdraft at LOW
speed and using the front surface unit.

3

Grease Filter

The efficiency of your downdraft depends on a clean
filter. Frequency of cleaning depends on the type of
cooking you do. Grease filters should be cleaned at
least once a month. Never operate the downdraft
without the filters in place.

To remove: Pull the filters out by grasping them and
pulling straight up.

To clean: Soak and then agitate in a hot detergent
solution. Light brushing may be used to remove
imbedded soil. Rinse, shake and remove moisture
before replacing.

With careful handling, the filter will last for years.
If replacement becomes necessary, order the part from
your dealer.

NOTE: The filters are different sizes. Be sure to
replace them with the longer filter on the left.

When replacing the filters, the long one goes in the
left side.

Plan the Ductwork

1. This downdraft blower system is designed
for use with 31⁄

4

″x 10″ ductwork (can be transitioned

to 6″ round). Three dif ferent discharge

directions are available with side--to-side
adjustment for accurate alignment of ductwork.

2. For best performance: Choose the ducting
option which allows the shortest length of
ductwork and a minimum number of elbows and
transitions. Check location of floor joists, wall
joists, wall studs, electrical wiring or plumbing
for possible interference.

NOTE: The unit is shipped with the 3

1

⁄

4

″ x 10″

discharge facing DOWN. See the Changing
Blower Direction section, if necessary.

Steps to Determine Flexible Ducting’s
Equivalent Length

1. Measure the actual amount of offset

(Maximum 3″ recommended). The effect upon

airflow is dependent upon the amount of offset.

2. Calculate the equivalent ducting allowances
using:

( ___ in. offset) x (14 Ft. per inch)
= ___ Ft. equivalent length.

3. Ensure that the total equivalent length of
ducting does not exceed the maximum
recommendation of 100 feet.

Plan the Wiring

1. The downdraft blower system draws 4 AMPS
and requires a 120 VAC, 60 Hz circuit.

2. The unit has a 2 ft. long power cord with a
3-pronged plug. Plan to provide a grounded
outlet in a location which will allow the unit’s
power cord to reach. The outlet cannot be
located on a back wall. The outlet needs to be
mounted on the side wall of the cabinet or it
could be on the back wall of an adjacent cabinet
with access through an opening in the side wall.
(Based on local codes.)
