6.5 CLEANING THE STEAM VENTILATION DUCTWORK
The Steam-Tech Plus ventilation ductwork system is made up
of a series of horizontal and vertical ducts. This series of duct-
work must be cleaned periodically in order to maintain cleanli-
ness. Frequency will vary according to use. The recommended
procedure for cleaning of the steam ventilation ductwork is con-
tained in this section.
NOTE: In order to perform this procedure, you must gain ac-
cess to the rear of the unit.
1.
Disconnect the 208/240/480 volt power supply.
2.
Disconnect the 120v power supply.
3.
Slide the unit out away from the wall (you may need to
disconnect the water inlet line).
4.
Remove the 11 screws which hold the louvered vent ac-
cess hatch onto the rear panel of the unit. (Refer to Figure
6.1 on page 6.2.)
5.
Using detergent and a damp cloth, wipe clean the inside of
both the upper and lower horizontal intake ducts, located
just above the cooking compartments. The very front of
these ducts may be accessed more easily from the front
of the unit.
6.
Using detergent and a damp cloth wipe clean the inside
of both the vertical intake and exhaust ducts. These ducts
are mounted onto the inside of the rear panel of the unit.
CAUTION: WHEN CLEANING THE VERTICAL EXHAUST
DUCT BE VERY CAREFUL NOT TO DAMAGE THE
BLOWER WHICH IS LOCATED AT THE BOTTOM OF
THE DUCT. LOOKING AT THE UNIT FROM THE REAR,
THE VERTICAL EXHAUST DUCT IT THE ONE ON THE
RIGHT.
