2.0 TOOL OPERATION
2.1 Using the Handrail Hoist, operate the winch to lower the mini-vacuum into
position.
NOTE: Once system is completely submerged close the drain valve located on the
bottom between the two tanks, using the supplied MLEP J-lock Mast Section. The valve
should be turned clockwise (CW).
2.2 Plug in VFD controller to an appropriate power supply. The readout will
illuminate.
2.3 On the Controller, verify that the REDIFL4 mode is activated. Screen should
display the following.
If display is not as shown, refer to Grundfos Instruction Manual.
2.4 To start the motor, Press the FWD Key and adjust the speed using the up and
down arrow keys on the control pad. (The max "speed" of the motor is when
MOTOR VOLTS reads approximately 230V on the display)
NOTE: MLEP testing indicated flow rates of approximately 50 GPM at max Voltage of
230V
2.5 When vacuuming is finished, press the STOP key.
2.6 If removing from the cavity, open the drain valve (1/4 turn counter clockwise-
CCW). This operation can be completed using the MLEP J-lock poles).
3.0 MAINTENANCE:
3.1 PUMP/MOTOR: Before each use, the component should be visually inspected
for abuse, worn/broken cable, secured bolts and screws, and pump and motor
flange o-ring shall be inspected.
NOTE: If necessary, the pump and motor assembly can be changed out remotely using
the MLEP J-lock mast sections. The female J-lock end located on the Pump and Motor
Assembly is spring loaded for this purpose. Insert the mast end into the J-Lock socket,
push down, and rotate CCW until it stops. Allow the spring to push the mast up and lock
into the Pump and Motor Assembly. The Pump and Motor Assembly can now be lifted
out of the Filter Housing.
