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.
