SYSTEM COMPONENTS
A Pump
Used to deliver the coolant in the tank to the machine.
B Gear Reducing Motor
Moves the filter media along as necessary.
C Liquid Level Control and Filtration
Float switch mechanism detects the level of coolant collected
in the filter valley. Switch operates the motor that moves the
filter media along when level is too high.
D Diffuser Tray
Collects larger particles before the coolant is deposited
on the filter media. Also helps spread deposits evenly,
increasing media life.
E Filter Media
Collects the particles to filter the coolant. Standard roll
is 150 yards, rated at 20 micron. Other micron ratings
available; contact Graymills for details.
F Sludge Box
Used to accumulate spent filter media and prevent run off to
floor.
G (Optional) Magnetic Separator

filter or tank. Can be installed directly on bed filter for dual
stage separation, or run independently with pumping system.
UNIT SET UP
1 Verify operating voltage and make any necessary changes
to the connections to the transformer in the control box as
well as the pump. The unit is a dual voltage system and
the default setting should be 230V/3Ph. Follow the wiring
schematics on the transformer and pump to check/change

All electrical connections should conform to national/local
codes and be made by qualified personnel.
2 Position the unit in the area in which it will be operating.

4 Fill the tank cavity with coolant until level is approximately
1 to 2 inches below side wall of tank, being careful not to
overfill.
5 Proceed to feed paper through the opening at the bottom of
the paper compartment and onto the chain until the chain

tank and place end of filter paper over box so soiled media
drops into box.

7 Pump and bed filter may be wired separately in the event
there is a power feed from your machine tool to incorporate
the pump operation into the main control. If not, you may
run a water-tight conduit (customer supplied) from the pump
to the main control box and bring your main power feed
into it for a central connection. All electrical work must be
according to applicable codes.
8 Make the necessary connections as shown in the wiring
schematic, Figure 3. All electrical work must be according to
applicable codes.
9 Complete any other necessary installations to finish the hook
up. This includes attaching hoses and fittings (customer-
supplied) from the pump discharge to the machine tool. The

capacity of the pump. Also plumb the return lines so they are
discharging directly onto the diffuser plate of the Bed Filter
or intake of the Magnetic Separator.
