SERVICE
REQUIRED
NOTE: Never press the POWER SWITCH to FRYER unless the HEATING ELEMENTS are
covered with either shortening (or, in the case of cleaning, water - NEVER MIX OIL AND WATER ).
Check the COLD OIL LINE for the proper shortening level.
NOTE: This fryer is designed to be used with LIQUID SHORTENING ONLY, unless it is
equipped with the solid shortening option (available only on model WVAE-55FS).
Lard and solid shortening will solidify in the filter pump, causing pump failure.
1. Verify that the CHARCOAL FILTER (if used), HEPA FILTER and GREASE BAFFLE are properly
installed in their respective locations. The HEPA FILTER and GREASE BAFFLE activate
MECHANICAL INTERLOCK SWITCHES when they are in their proper position. Activating both
mechanical interlock switches energizes the heating element.
The CHARCOAL FILTER does not activate a position sensor, thus the ventilator may be operated
without this optional filter.
A pressure tap on the blower housing and a vacuum tap downstream of the filters (but before the
blower) feed pneumatic signals to the AIRFLOW VACUUM SWITCH and to the SERVICE FILTER
VACUUM SWITCH.
2. Press the POWER SWITCH to the FRYER position:
a. The BLOWER will start and the VENTILATOR POWER ON (green light) will light.
b. The TEN SECOND DELAY RELAY will be energized, bypassing the AIRFLOW VACUUM
SWITCH during the ten-second countdown.
3. If, after the ten second delay, sufficient air flow is sensed by the AIRFLOW VACUUM SWITCH , the
BLOWER will continue to run and the fryer will be energized.
4. If, after the ten second delay, sufficient air flow has not been sensed by the AIR FLOW VACUUM
SWITCH, the BLOWER will shut down and the SERVICE REQUIRED (red light) will be lit.
5. If either the HEPA FILTER or GREASE BAFFLE should be removed or become dislodged, the
respective MECHANICAL INTERLOCK SWITCH will open, the fryer will be de-energized and the
CHECK FILTERS (amber light) will light.
6. If either the HEPA FILTER or the CHARCOAL FILTER, or in combination, become partially clogged,
the SERVICE FILTER VACUUM SWITCH will close and the REPLACE FILTERS (amber light) will
light. The fryer will continue to operate. This is a WARNING that the filters are approaching the end
of their service life. The filter(s) must be replaced before they become so clogged that the fryer/
blower is shut down by the AIR FLOW VACUUM SWITCH.
381 502944 Service Manual for NFPA Hood
5
IMPORTANT: When the REPLACE FILTERS (amber light) comes on, the fryer will soon shut
down. The actual time between the light coming on and the fryer shutting down depends upon the
type and quantity of product being cooked. The operator must prepare to change the filter(s) by
making sure that fresh replacement filters are on hand at the fryer location.
7. If either the HEPA FILTER or the CHARCOAL FILTER, or in combination, become clogged to the
point that sufficient airflow is not sensed by the AIRFLOW VACUUM SWITCH, the switch will open.
The BLOWER will shut down, the fryer will be de-energized and the SERVICE REQUIRED (red
light) will light.
The manufacturer recommends replacing both the HEPA FILTER and the CHARCOAL FILTER at
the same time. Verify that the air flow arrows point toward the fan.
After the filter(s) are replaced, the POWER SWITCH must be pressed to OFF, then back to FRYER
to reset.
8. Any loss of electrical power will disable the fryer. After power is restored, the POWER SWITCH
must be pressed to OFF, then back to FRYER to reset.
9. The fryer is de-energized anytime the Ansul® fire suppression system has discharged, or is
otherwise is not CHARGED and COCKED. The BLOWER will continue to run.
10. Both the fryer and the BLOWER are de-energized when the POWER SWITCH is in the FILTER
position.
11. Control power is routed through a jumper at the REMOTE INTERLOCK TERMINAL BLOCK.
For installations where remote shut-down is required, the jumper is removed and power is routed
through the remote interlock circuit.
Both the fryer and the BLOWER are de-energized when the remote interlock circuit is open.
12. Some jurisdictions require that an alarm signal be generated should the fire suppression system be
activated. A set of dry contacts are provided at the BUILDING ALARM RELAY for this purpose.
IMPORTANT: DO NOT connect power to the building alarm relay.

FILTER INTERLOCK ASSEMBLY INSTRUCTIONS
There are two FILTER INTERLOCK assemblies.
a. The GREASE BAFFLE interlock is on the left.
This assembly uses the LONG LINK so that the PAWL
fits into the front filter rail.
b. The HEPA FILTER interlock is on the right.
This assembly uses the SHORT LINK so that the PAWL
fits into the rear filter rail.
1. Install two SET SCREWS into the edge of each
INTERLOCK BLOCK.
2. With the INTERLOCK BLOCK laying flat, the set screws
pointing away from you, and the set screw that is closest
to the end in the upper right corner, insert a BUSHING in
the right hole, and insert a BUSHING in the left hole (for
the GREASE BAFFLE INTERLOCK), or in the middle
hole (for the HEPA FILTER INTERLOCK). (Fig. A)
3. Install a MAGNET in the MAGNET ARM. Align the
magnets so they repel each other when they are in
the normal operating position. (Fig. B)
4. Assemble the PAWL and the MAGNET ARM to the LINK.
The short leg of the “L” slot will point down. Slide the link
into the top slot of the small studs. Use the LONG LINK
for the GREASE BAFFLE INTERLOCK, and the SHORT
LINK for the HEPA FILTER INTERLOCK. (Fig. C)
Slide the large studs into the BUSHINGS and secure
with “E” CLIPS. The pawl and arm should operate freely.
5. Push the SET SCREWS through the appropriate holes in
the filter rail and secure with nuts. The pawl and arm
should continue to operate freely.
6. Install the COVER and secure with two screws from the
filter rail side.
7. Install the PROXIMITY SWITCHES on the ledge in the
blower section. The switches must be installed with the
thickest edge against the wall. Before tightening the screws,
push the switches as far forward and as far apart as they will
go.
8. Check operation with an ohm meter on the leads of the
PROXIMITY SWITCHES while pressing and releasing
the PAWLS. With the pawl depressed, the reading
should be zero ohms.

STATUS SENSOR CHECKOUT PROCEDURES
1. The Ansul® system must be ”cocked” before system operation
and checkout is possible.
Make sure the heating elements are covered with oil before
beginning checkout.
2. Remove GREASE BAFFLE, HEPA FILTER and CHARCOAL
FILTER. Press the POWER SWITCH to FRYER. You should see:
VENTILATOR POWER (green light) ON
CHECK FILTERS and REPLACE FILTERS (amber lights) ON
Within 2 - 4 seconds, REPLACE FILTERS (amber light) should
go OFF
Heating element will be OFF
3. Verify that the FILTER MECHANICAL INTERLOCK PAWLS
operate independently of each other. If not, the magnets will need
to be re-aligned (see page 9).
With both pawls pressed, CHECK FILTERS (amber light) should go
OFF, and the heating elements should be energized.
4. Install the CHARCOAL FILTER first (be sure the plastic shipping
bag is removed), then the HEPA FILTER, followed by the
GREASE BAFFLE. Note the airflow arrows. The arrow must point
toward the blower. The CHECK FILTERS (amber light) should go
OFF.
5. Begin covering the GREASE BAFFLE with cardboard. Work slowly
so that the sensors have time to react. To be sure the sensor does
not “flutter”, wait at least 20 seconds after a response before
proceeding. With fresh, clean filters:
a. When 90% of the filter is covered, REPLACE FILTERS (amber
light) will go ON
b. When only 1” of the GREASE BAFFLE remains uncovered,
SERVICE REQUIRED (red light) will go ON and the unit will
shut down (i.e. elements de-energized and all other
indicator lights OFF).
6. Reset the fryer by removing the cardboard blocking the filter, then
pressing the POWER SWITCH to OFF then back to ON.
7. If the Ansul® systems trips, a continuous buzzer will sound.
VENTILATOR POWER (green light) will remain ON, but the
heating elements will be de-energized.
NOTE: On units with solid state
control, the HEAT light being on
is not a guarantee the elements
are in fact energized!
IMPORTANT: Before installing
the CHARCOAL FILTER, be
sure the plastic shipping bag is
removed.
Simulate grease build-up by
using an 18” wide X 24” long
piece of cardboard. Working
from the bottom, cover the
ventilator opening gradually until
the sensors react.
