Spring Air Systems Water Wash Ventilator Maintenance Manual 11/01

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.
