Spring Air Systems Water Wash Ventilator Maintenance Manual 11/01

MODELS: MP10C, MP10H
CAPACITY:
One ¾” (19 mm) to 1.5” (38 mm) hot water inlet and one ¾” (19 mm) to 1.5” (38 mm) hot water outlet connections for
washing up to 50 ft. (15 m) of ventilator.
When the selector switch has been rotated to the “OFF” position, after a 60 second time delay, the blue “WASH” pilot the
detergent pump and hot water solenoid valve are energized. The hot water and detergent mixture flow to the ventilator
and enter the grease extractor through an inlet pipe connected to the spray manifold. The detergent water mixture is
sprayed from nozzles spaced uniformly along the length of the wash manifold washing the grease dirt and lint from the
grease extractor baffle and into the drain.
The wash continues for the period of time set on the wash timer adjustable from 0 to 600 seconds. At the end of the
wash cycle the blue “WASH” pilot, the detergent pump and the hot water solenoid valve shut off. The system remains
idle until the next time the fan selector switch is turned to the “ON” position.
