The float switch in the suction cycle relay
holding circuit causes this circuit to drop out
at a predetermined liquid level in the tank,
preventing overfilling and pump damage.
The discharge circuit has no such float switch,
therefore, the cleaner must be plugged into
outlets that are uniformly phased, so that
operating the SUCTION button rotates the
motor and pump in the correct direction.
Connection to improperly phased outlets
can void the warranty on this machine.
B. Test the outlet phasing by pushing the
SUCTION button and verifying whether
the cleaning tool is actually sucking. If not,
the outlet phasing must be modified by
authorized service personnel.
5. For suction operation:
Open the inlet ball valve,
V1, fully. Make sure all female quick disconnect
caps are on the male fittings on the clean side
and the dirty side discharge port. Place the float
switch selector toggle switch on the control panel
to the “Filter” position, then press the SUCTION
button to start the motor and vacuum coolant
and chips from the sump.
A. IMPORTANT! Be sure the toggle switch on
the control panel is in the Filter position so
the float switch in the dirty side will be in the
suction circuit to shut the unit off when full.
Failure to do so will allow the unit to overfill
and spill fluid out the mufflers onto the floor.
6. As soon as fluid stops passing through the hose,
press the STOP button to turn off the motor.
A. The compartment’s maximum capacity is, at
most, 10% above the rated capacity. The float
switch described in Paragraphs 3 and 4
above, and located near the compartment
suction fitting, will shut off the motor if
overfilling starts to occur.
7. To return filtered chip-free coolant to
the sump, or wash down the machine, or
discharge dirty coolant into your recycling
or disposal system:
close the suction inlet ball
valve V1, attach the 1-1/2" hose to the discharge
port, place the discharge nozzle in the machine
sump, push the DISCHARGE button, and depress
the discharge hose nozzle valve.
A. Be sure the suction inlet ball valve is
fully closed before operating in the
DISCHARGE mode!
B. IMPORTANT! Be sure the suction inlet ball
valve is fully closed or fully open, depending
on the desired operation (closed-discharge,
open-suction). Failure to do so will allow
particulates to enter the valve seat and
seize the valve.
C. Stop the motor as soon as fluid stops passing
through the hose.
D. The sump cleaner will discharge all but
about an inch of fluid in the bottom of the
compartment. This is unimportant if the
compartment cleaner is used for one type
of coolant only. If different coolants are to be
handled in that compartment, remove its drain
plug to empty it completely.
8. To fill the clean side with clean fluid:
A. Close the suction inlet valve V1, fully, attach
1-1/2" hose to the clean side inlet port, remove
the discharge nozzle from the other end of the
1-1/2" hose and attach it to a clean fluid tank,
select “Auxiliary” position on the float switch
selector toggle switch, and press SUCTION.
B. IMPORTANT! Be sure the suction inlet ball
valve is fully closed or fully open, depending
on the desired operation (closed-discharge,
open-suction). Failure to do so will allow
particulates to enter the valve seat and
seize the valve.
C. IMPORTANT! Be sure the toggle switch on
the control panel is in the Auxiliary position
so the float switch in the clean side will be in
the suction circuit to shut the unit off when full.
Failure to do so will allow the unit to overfill
and spill fluid out the mufflers onto the floor.
D. As soon as fluid stops passing through
the hose, press the STOP button to turn
off the motor. The compartment’s maximum
capacity is, at most, 10% above the rated
capacity. The float switch described in
Paragraphs 3 and 4 above, and located near
the compartment suction fitting, will shut off
the motor if overfilling starts to occur.
