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 SECTION - OPERATIONAL NOTES (continued)
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.

The FIRE DAMPER sets in the DAMPER SUPPORT and may be

SV502 SvcManual WVG-136(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.

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.

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.

Interior of drawer warmer cavity will
be hot during operation. Allow unit
to cool before performing any
service.
NOTE:
In the absence of a drawer warmer
appliance, the WVG-136 is
equipped with a storage cabinet in
the base. This single cabinet has
two doors.
1. The optional drawer warmer unit is a Wells RW-26HD or
RWT-26HD two-drawer roll warmer unit.
2. The drawer warmer has two individually controllable sections.
a. Control of RW-style unit is via bulb and capillary
thermostat with SPST switch.
b. Control of RWT-style unit is via electronic controller.
3. Each section is heated by a single element of roughly
rectangular configuration.
4. Drawer warmer is powered by the drawer warmer relay
5. Optional dial thermostat may be located on either or both
drawer sections.
6. Digital controller will replace thermometer-equipped units in
new production. Thermometer-equipped units are to become
obsolete.
