An integral part of any SPRING AIR SYSTEMS water wash ventilator is the water wash control panel. The water wash
control panel controls the exhaust fan operation the daily wash and second line fire protection system.
CONTROL PANEL OPERATION
Sequence of Operation: All panels
Exhaust fan: To start the exhaust fan rotate the fan selector switch to the “ON” position. The green “FAN ON” pilot and
exhaust fan will turn on. The exhaust fan starter coil is energized through terminals 3 and 4 in the water wash control
panel.
Supply fan: Power is provided for a fresh air motorized shut off
damper through terminals 4, 8, & 9. The damper motor is energized
through terminals 4, & 8. Once an end switch closes 120V/1/60
power is supplied back to the control panel through terminal 9. The
supply fan motor starter is then energized through terminals 4 & 9.
When a motorized damper with end switch is not used in the
installation the field electrician must jumper terminals 8 & 9 in the
water wash panel to provide 120V/1/60 power to the supply fan motor
starter.

Cold Water Spray Panels (SB10C/MPx0C/APx0C)
When the fan selector switch is rotated to the “ON” position the cold water spray solenoid valve is energized. The cold-
water spray operates while the exhaust fan is operating. The cold-water spray can be observed by looking into the inlet
slot of the grease extractor. All nozzles should be spraying to form a uniformed water pattern along the length of the
ventilator.
To stop the exhaust and supply fan rotate the selector switch to the “OFF” position. The green fan “ON” pilot and the
exhaust fan will turn off.

REMOTE PIPING
All remote piping must meet applicable local plumbing codes.
The panel must be installed with adequate protection to stop
the flow of detergent back into the potable water supply. This
may be accomplished, depending on the municipality, with a
vacuum breaker and check valve assembly or a back flow
preventor. SPRING AIR SYSTEMS will always prepipe the
detergent line into the main hot water outlet pipe in the
plumbing cabinet unless advised to do otherwise prior to
shipment.
IT IS IMPORTANT TO CHECK WITH LOCAL PLUMBING
INSPECTORS TO DETERMINE WHAT IS ACCEPTABLE
PRACTICE IN YOUR JURISDICTION.
Backflow Preventor Vacuum Breaker
Figure 10
CLEANING THE EXTERIOR
Normal soil can be removed with a mild detergent water mixture applied to a cloth.
To remove baked on grease, apply a cleanser to a damp cloth or sponge and rub on the metal in the direction of the
polishing lines. DO NOT RUB IN A CIRCULAR MOTION. Burnt deposits, which do not respond, can usually be removed
by rubbing the surface with SCOTCH-BRITE scouring pads or STAINLESS scouring pads. Do not use ordinary steel
wool. Heat tint can be removed by a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE or
STAINLESS scouring pads in conjunction with powdered cleanser.
Once the wash cycle(s) are complete wipe of the interior surface of the ventilator canopy and the underside of the grease
trough and skirt.
During the wash cycle(s) condensation may form on these surfaces. The condensation will assist in cleaning off any
grease, dirt or lint, which may have built up during the daily operation.

WASH TIMER SETTINGS
All SB10C, MP10C, MP20C, MP30C, MP40C, & MP50C wash control panel timers are factory set at two minutes.
All SB10H, MP10H, MP20H, MP30H, MP40H, & MP50H wash control panel timers are factory set at three minutes.
After the first four days of operation open the front access door on the grease extractor. Visually check if the baffle and
interior surfaces are clean. If there are grease deposits check that the hot water pressure is between 40 psi (2.8 kg/cm2)
and 70 psi (4.2 kg/cm2) and the hot water temperature is between 120 F (49 C) and 180 F (82 C). If there is adequate
temperature and pressure either use a higher detergent concentration or increase the wash time.
• The detergent concentration can be adjusted by increasing the cam setting on the side of the detergent pump.
Loosen the wing nut on the side of the detergent pump and rotate the cam to the next setting. The cam is
adjustable from 0 to 6, 6 being the highest detergent concentration. Only increase one setting at a time. Inspect
the interior each day and adjust until all surfaces are clean.
• Only increase the wash time in 30-second intervals until all baffles and exposed interior grease extractor surfaces
are clean.
For type “C” water wash ventilators check that the cold water pressure is at least 10 psi 1.4 kg/cm2).
AUTOMATIC WASH SYSTEMS:
SBA10H, SBA10C, AP10H, AP10C, AP20H, AP20C, AP30H, AP30C, AP40H,
AP40C, AP50H, & AP50C
The automatic wash control panels are equipped with a solid-state microprocessor. The fan
selector switch is replaced with a three-position “OFF/AUTO/ON” switch. In the “OFF” and “ON”
positions the control panel operates identical to the standard SB, & MP manual wash panels.
When the fan switch is rotated to the “AUTO” position the solid-state time clock controls the
OFF/ON operation of the exhaust fan, supply fan and wash cycle.
Setting the clock (T6) is as simple as setting a digital watch.

GREASE EXTRACTOR OPERATION
TYPE “C” GREASE EXTRACTOR
The SPRING AIR SYSTEMS type “C” grease extractor has the highest grease
extraction efficiency available in a water wash ventilator.
The contaminated exhaust air enters the high velocity inlet slot A and flows
through a transition zone to the VORTEX CHAMBER B. The cold-water spray
manifold D sprays a fine cold-water mist into the path of the exhaust air. The
cold-water spray causes the grease particles to cool, congeal and coagulate
forming larger grease globules. The larger heavier globules are more readily
removed through centrifugal force as the exhaust air accelerates through a
complete 270-degree turn around the VORTEX BAFFLE C. The grease, dirt
and lint are deposited on the PRIMARY VARIABLE FLOW BAFFLE G and the
VORTEX BAFFLE C. The PRIMARY VARIABLE FLOW BAFFLE G is also
adjustable along the length of the grease extractor to provide varying exhaust
airflow. The sloping VORTEX BAFFLE C drains the collected grease to the
end of the ventilator into a grease trough.
Type “C” Extractor
Figure 13
The cold-water spray extends from the entrance to the exit of the VORTEX CHAMBER B, which provides a secondary
coverage as the exhaust air enters the secondary grease extraction chamber. The exhaust air continues into the
secondary extraction chamber, which contains an additional baffle, F. Residual grease is deposited on the secondary
baffle as the exhaust air gyrates through the secondary chamber. After leaving the secondary chamber the exhaust air
enters the ventilator fire damper and duct collar and discharges into the ductwork.
TYPE “H” GREASE EXTRACTOR
The SPRING AIR SYSTEMS type “H” grease extractor is a high
efficiency water wash grease extractor.
The contaminated air enters the high velocity inlet slot A and flows
through the transition zone to the VORTEX CHAMBER B. The
exhaust air accelerates through a complete 270-degree turn around
the VORTEX BAFFLE C. Centrifugal force causes the grease, dirt
and lint particles to deposit on the PRIMARY VARIABLE FLOW
BAFFLE G and the VORTEX BAFFLE C. The PRIMARY
VARIABLE FLOW BAFFLEG is also adjustable for varying exhaust
flows along the length of the extractor. The sloping VORTEX
BAFFLE C drains the collected liquid grease to the end of the
ventilator and into the grease trough.
The exhaust air continues into the secondary extraction chamber,
which contains an additional baffle, F. Residual grease is
deposited on the secondary baffle as the exhaust air gyrates
through the secondary chamber. After leaving the secondary
chamber the exhaust air enters the ventilator fire damper and duct
collar and discharges into the exhaust ductwork.
Type “H” Extractor
Figure 14

Spring Air Systems Water Wash Ventilator Maintenance Manual 11/01 15
TYPE “D” GREASE EXTRACTOR
The SPRING AIR SYSTEMS type “D” grease extractor is a
high efficiency dry grease extractor. The type “D” grease
extractor removes grease, dirt and lint through centrifugal
force. Removing the front access door and wipe the interior
with a damp cloth to manually clean the grease extractor
chamber
Principle of Operation
The contaminated exhaust air enters the high velocity inlet
slot A and flows through the transition zone to the VORTEX
CHAMBER B. The exhaust air accelerates through a
complete 270-degree turn around the VORTEX BAFFLE C.
Centrifugal force causes the grease, dirt and lint particles to
deposit on the PRIMARY VARIABLE FLOW BAFFLE G and
VORTEX BAFFLE C. The sloping VORTEX BAFFLE C
drains collected grease to the end of the ventilator into the
grease cup H.
The exhaust air continues into the secondary extraction
chamber, which contains an additional baffle, F. Residual
grease is deposited on the secondary baffle as the exhaust
air gyrates through the secondary chamber.

VENTILATOR GREASE EXTRACTOR SYSTEMS : TYPE “C”, “H” & “D”
SPRING AIR SYSTEMS ventilators are available with either automatic or manual wash systems. All water wash
ventilators must be interconnected with a water wash control panel.
Manual: Type “D” Ventilator
The type “D” incorporates a grease extractor similar to
type “H” but without the wash manifolds. The type “D”
is recommended for light to medium cooking
applications where grease is minimal.
The liquefied grease collects on internal baffles as
described in the “Grease Extractor” section of the
manual. The baffles are designed to drain the
liquefied grease to the end of the ventilator and into the
grease trough and grease cup.
To clean the grease extractor, the front access door
and grease cup are removed and manually washed in
a kitchen sink.
The two interior baffles and grease trough should be
wiped down with a damp cloth soaked in a water and
mild detergent mixture. If the cooking application
generates high temperatures, the grease trough may
require additional cleaning and/or scraping to remove
baked-on solidified grease.
Type “D” Grease Extractor
Figure16

_____________________________________________________________________________________________
Spring Air Systems Water Wash Ventilator Maintenance Manual 11/01 16
Automatic Wash: Type “C” and “H:” Ventilators
The “C” and “H” ventilators have incorporated water wash manifold into the high efficiency grease extractor. The
PRIMARY BAFFLE C and SECONDARY BAFFLE F are both water wash manifolds.
Spray nozzles are spaced evenly along baffle/manifolds. The hot detergent water mixture enters the hot water inlet pipe,
and travels into the interconnecting pipe to the PRIMARY BAFFLE/MANIFOLD D and the SECONDARY
BAFFLE/MANIFOLD F. The water detergent mixture is sprayed uniformly within the interior of the grease extractor.
The water/detergent mixture washes the grease, lint and dirt into the sloping
VORTEX BAFFLE , which carries the mixture to the end of the ventilator, and into
the grease trough. The mixture travels along the grease trough to the drain. The
drain may be located at either end of the ventilator. Multiple ventilators may have
individual drains factory manifold to one common drain.
The wash time is adjustable from 0 to 10 minutes. The type “C” is normally set at 2
minutes while the type “H” is set at 3 minutes. Depending on the type of cooking
equipment the type “C” usually requires less hot water wash time because of the
continuous cold-water spray. During fan and cooking operation, the spray
continuously carries grease, dirt and lint down the drain, which reduces the daily
grease build-up.
The hot water required is approximately 1 gpm/ft. of ventilator at 40 psi (see Chart
No.1 and No. 3)
The cold-water continuous spray requires approximately 1.0 gph/ft. of ventilator at 15
psi (see Chart No.2 and No. 4)
See figure 19 for electrical and plumbing requirements for type “H” grease
extractors.
Type “C” and “H” Wash
Figure 17
The hot water wash manifold can be viewed by removing the front access doors on the water wash grease extractor.
Make sure the fan has been switched off and the wash is complete before opening these doors. All wash nozzles are
directed from the middle of the water wash grease extractor towards the two ends. One wash nozzle is located on a
manifold extending up towards the exhaust duct collar. This nozzle washes the exhaust fire damper and fusible link.
Wash water is therefore directed straight out the duct collar into the exhaust duct. If water is found on top of the hood
check for leaks in the exhaust ductwork connected to the hood. If the wash water pressure is over 70 psi over spray
many occur at the ends of the grease extractor. Open the access door and rotate the wash nozzles counter clockwise 45
degrees starting with the nozzle closest the end of the grease extractor. Continue until over spray stops.
