Three Sequence Wash Panel Models AP30C and AP30H Electrical
Figure 8
The detergent water mixture washes the first group of ventilators (up to 50-ft. (15m)). The wash cycle continues for the
length of time set on wash timer #1 (T1), adjustable from 0 to 600 seconds. At the end of wash cycle #1 the blue WASH
#1” pilot and the hot water solenoid valve #1 shut off and the blue “WASH #2” pilot and hot water solenoid valve #2
energize. The detergent and water mixture washes the second group of ventilators (up to 50 ft. (15m)). The wash cycle
continues for the length of time set on wash timer #2, adjustable from 0 to 600 seconds. At the end of wash cycle #2 the
blue “WASH #2” pilot and the hot water solenoid valve #2 shut off and the blue “WASH #3” pilot and the hot water
solenoid valve #3 energize. The detergent water mixture washes the third group of ventilators (also up to 50 ft. (15 m)).
At the end of wash cycle #3 the blue “WASH #3” pilot the hot water solenoid valve #3 and the detergent pump shut off.
The system remains idle until the next time the fan selector switch is rotated to “ON” position.
FOUR AND FIVE SEQUENCE WASH SYSTEMS
Four and five sequence wash control panels operate similarly
to the three-sequence wash. After the third wash cycle is
complete the system proceeds to the fourth and fifth wash
cycles.
Due to space limitations within the kitchen the four and five
sequence wash system also have remote solenoid valves.
The detergent pump and tank are still located in the wash
control panel. See wiring and piping diagrams in the back of
the manual for the four and five sequence wash systems.
