(RED) SERVICE
REQUIRED
Indicates that either the pre-filter or the filter pack is
individually clogged (the individual indicator light
may be lit), or that the the airflow drop across both
filters is critical. As a cost saving measure, always
change a dirty pre-filter first (when lights V.04 &
V.05 are not lit, and red light V.06 is on).
Note: Power to the cooking appliance will be
de-energized whenever this RED “SERVICE
REQUIRED” indicator light is lit. When lit, the air
flow is insufficient to meet appliance vapor capture
levels requirements.
Controlled by vacuum switch S4.

VENTILATOR HOOD
Energizes the ventilator section. When all three
filters are sensed as being in their proper position,
and sufficient airflow is proven, the cooking
appliance contactor is energized.
HOOD OPERATION - OPERATIONAL NOTES
WARNING:
FIRE AND HEALTH
HAZARDS
VENTILATOR HOOD
DO NOT bypass or attempt to
bypass the filter placement
interlocks. Operating the
appliance without filters properly
in place will compromise the fire
protection and air filtration
capabilities of this unit.
Serious personal injury and/or
substantial property damage may
result.
NOTICE:
Operating without all filters
properly in place, and/or
operating with filter placement
interlocks defeated will void the
manufacturer’s warranty.
IMPORTANT:
NEVER wash the PREFILTER or
FILTER PACK.This will shut
down the cooking appliance.
(Red “SERVICE REQUIRED”
light will turn ON).
REPLACE PREFILTER and REPLACE FILTER PACK indicator lights
provide a timely warning that a system shut-down is imminent. The
actual time between the indicator light coming on and the loss of
cooking appliance power will depend upon the cooking conditions.
Anytime a dirty PRE-FILTER is replaced, the system airflow will
increase. If the condition of the FILTER PACK is marginal, the
REPLACE FILTER PACK light could then come on. If this happens, a
fresh FILTER PACK must be installed within a reasonably short time.
Loss of airflow through the old filter pack will soon cause a system
shut-down when the airflow falls below minimum vapor capture levels.
KEEP SPARE FILTER PACKS ON HAND.
IMPORTANT: If you decide to “get the most” out of the old filter pack,
and continue to use it until a system shut-down happens, it is advisable
to have a fresh filter pack readily at hand, and have someone available
who is capable of replacing it. Otherwise, you may experience an
extended down time, with consequent associated loss of business.
The manufacturer assumes no liability for loss of business due to
a system shutdown caused by a dirty pre-filter and/or filter pack
(i.e. red SERVICE REQUIRED light is on), when the user fails to
have the proper replacement pre-filter and/or filter pack on hand.

1. The FIRE DAMPER is accessible by removing the TOP PANEL
The FIRE DAMPER sets in the DAMPER SUPPORT and may be
removed by lifting straight up.
SV507 SvcManual WV-FG(RW))
2. The FIRE DAMPER normally needs no maintenance. If it
becomes heavily contaminated with dust and/or grease, it must
be replaced.
3. If the FIRE DAMPER malfunctions or if the fusible link releases,
the manufacturer recommends that the entire FIRE DAMPER
ASSEMBLY be replaced.
4. Reinstall the FIRE DAMPER with the “THIS SIDE UP FOR
HORIZONTAL MOUNTING” arrow pointing away from the
BLOWER.
11
IMPORTANT:
Replace the entire fire damper
assembly if the link trips, or if the
damper mechanism becomes
heavily contaminated with dust
and/or grease.
While the fusible link alone may be
replaced, once the damper has
tripped it may no longer function
reliably.

GREASE
BAFFLE
1. The GREASE BAFFLE separates grease particles and water vapor
from the air stream by the centrifugal force of the air moving through
its inter-leaved baffle plates. Ejecta is collected in the GREASE CUP
through drain holes in the baffle frame and cabinet.
The GREASE BAFFLE POSITION MONITOR plunger switch controls
electric power to the ventilator fan.
NOTE:
The charcoal portion of the
filter pack is an aid in
controlling cooking odors
only. It will not completely
eliminate such odors.
2. The PRE-FILTER is composed of a replaceable media filter and a
filter-retaining gage. The pre-filter captures the bulk of grease vapors.
Pre-filter position is monitored by a vacuum switch, which is in the
control circuit of the cooking appliance contactor.
3. The FILTER PACK is composed of a high-efficiency filter to capture
grease vapors down to a very small particle size; and, an activated
charcoal filter to help control cooking odors.
The FILTER PACK POSITION MONITOR plunger switch is in the
control circuit of the cooking appliance contactor.

FRYER SECTION - PERIODIC CLEANING
CAUTION:
PERIODIC CLEANING
BURN HAZARD
Add 1/2 cup of granulated dishwasher detergent to frypot. Fill with water
to the MAX OIL line.
Be sure frypot and
elements are dry before
returning unit to service.
Water left in the frypot will
boil off when heating,
splattering hot oil.
Lower the element into the frypot and set the control knob to 225ºF
Boil the mixture for five minutes. Turn the control knob to OFF. Allow the
mixture to set in the frypot overnight.
After the soak period, raise the elements and remove any remaining
carbonization with a stiff bristle brush. Be careful that the capillary tubes
of the thermobulbs are not moved or damaged during cleaning.
CAUTION:
Drain the frypot and wash with warm water and mild detergent.
BURN HAZARD
Reinstall the frypot in the fryer. Add 1 quart of vinegar, then fill to the MAX
OIL line with cold water.
Before cleaning, ALWAYS:
• Disconnect fryer from
electric power and allow
to cool.
• Drain the oil and wipe
out the frypot.
Lower the elements into the vinegar solution. Allow to set for 15 minutes.
Drain the frypot and rinse with clean water. Dry the frypot and elements
thoroughly before returning the fryer to operation.
IMPORTANT: Nickel plated frypot must be dried completely in order to
prevent rusting, and to eliminate water contamination of the cooking oil.
Periodic cleaning is
necessary to remove
carbonization from the
elements and frypot.
Frypot may be cleaned by
the method described at
right, or with a commercial
frypot cleaner. Be sure to
follow the manufacturer's
directions.

CAUTION:
1. Turn temperature control to OFF.
2. Allow the oil to cool to a safe temperature (120ºF or 50ºC).
3. Raise the element head and lift the frypot out of the fryer by the
frypot handles.
4. Dispose of the used oil in an approved oil disposal receptacle, or
filter the oil for reuse.
SLIP AND FALL
HAZARD
Clean up oil spills
immediately. Slipping in oil
can cause injury.

A. REMOVE ELEMENT HEAD FROM FRYER
Note: Some operations can be performed without removing the
fryhead. However, doing so will ease access to components and
fasteners.
1. Remove two screws holding either element head pivot.
Remove pivot.
2. Lift element head assembly from fryer.
3. Remove bottom cover from control box.
B. DISCONNECT ELEMENT
1. Disconnect the wiring from the element terminals.
2. Note position of each thermobulb and the routing of the capillary
tubes. Remove bulbs from element by removing two bulb clips and
three capillary clips from each bulb.
3. Undo both holding nuts from terminal end of the element.
4. Withdraw the element from the control box.
C. INSTALL NEW ELEMENT
1. Wipe area around element openings in control box to remove any
grease or other cooking debris.
2. Slide one fiber washer over each end of the new element.
3. Insert element into the control box. Slide a lock washer over each
element, then thread on the holding nuts. Make sure the element
is square with the control box. Tighten holding nuts.
4. Reconnect wiring to the element terminals.
5. Reinstall the thermobulbs. Be sure a bulb clip is in place at each
end of the thermobulb.
NOTE: Control and HI-Limit thermobulbs may require different
bulb clips. Refer to parts list for proper component.
Snap a bulb clip over the element to secure the bulb. Carefully
route the capillary tube and secure with three capillary clips.
Repeat for both bulbs.
D. REINSTALL ELEMENT HEAD ON FRYER
1. For F-49, be sure the pivot washer is in place on the pivot brackets.
While holding the support rod in the forward position, slide the
element head assembly onto the fixed pivot. Reinstall the pivot
removed In step A.
Test fryer for proper operation and return to service.
