5. Operating Instructions
The operator interface consists of five pilot devices: (1) Percent Saturation Water in Oil Display; (2) a blue “DRAIN
CYCLE” Light. The Master Stop (3) push-pull red button; (4) a “DRAIN/OFF/AUTO” Selector switch, which illuminates
when the unit is running in Auto Mode; and (5) a red “CHANGE FILTER” Light. The unit will start its normal cycle when the
user turns the selector switch to “AUTO”. The High Level Light (6) shows when fluid is above maximum level in chamber.
5.1 Percent Saturation Water in Oil Display
The digital display (1) provides a readout of the saturation water level as the fluid enters the pump.
5.2 Fluid Oscillation in AUTO Mode
WARNING!
During initial start-up of the MAFH-A unit, the suction line should be flooded with fluid to prime the
MAFH-A pump. Do not run the pump without fluid in the suction line or pump damage will occur!
The system fluid is cycled through the reaction chamber in-between two level switches. During the first cycle, fluid is
pumped and gently sprayed on top of the loose, reticulated media until the fluid level in the pump triggers the high float
switch. The fluid is then pumped from the sump and returned to the customer reservoir.
The blue “DRAIN CYCLE” light (2) will illuminate when the high float switch is triggered and remain lit until the pump’s fluid
level is below the lower switch. At any point during normal operation the element becomes clogged or enters into bypass
the red “CHANGE FILTER” light (5) will illuminate, notifying the user the particulate filter element needs replaced.
5.3 Drain Mode
Drain mode is available for service and maintenance reasons. The user will have to move the selector switch to “DRAIN”
and hold the switch in that position. The motors will run and blue “DRAIN CYCLE” light (2) will illuminate as long as the
user holds the switch. Release switch immediately after air discharges from the unit.
