Section 2 –General Operating Instructions
1. Electric Units:
Check electric cord for wear and grounding. Plug the unit into a 110/1/60 outlet.
2. Air Operated Units:
The unit requires a minimum of 15 psi at 0.5 SCFM air flow to operate. Ensure
the left hand bowl on the control unit is 3/4 full with pneumatic lubricant. The
lubricator is set at the factory. If you need to adjust the lubricator, turn the
tapered screw counter-clockwise on the lubricator to increase the rate. If you
need to decrease the rate turn the screw clockwise.

3. Pre Filters:
To change/clean the pre-filter begin by removing the suction head from the fluid
so the pump is sucking air only. Do this for 30 –60 seconds until you observe the
liquid level in the filter housing drop about and inch. Stop the pump via the air
valve or switch.
Unscrew the filter bowl, remove the filter and wash or replace it. Replacement
filters (part no 171-0011) are sold in case lots of 30. A Permanent Washable
Filter Strainers is supplied as an option. Contact the parts department for
replacement filters.
4. Adjusting Pump Rate:
The pump rate on the electric unit is preset and fixed. The pump rate on the air
operated unit is adjustable by turning the black knob on the air regulator up or
down. Clockwise increases the pressure and pump speed and counter-clockwise
decreases the pressure and pumping speed. The normal pump rate for the air
pump is about 40 -60 beats per minute. After adjustment, press the knob down in
the locking position.
5. Installation Procedure:
The unit should be operated on a level, solid base with brakes engaged on the
casters. All outlet pipes should have the shortest possible run length.
(A First Time installation procedure is supplied separately).
6. Start-up Procedure:
IMPORTANT: Follow the First Time Installation and Start-up Procedure
Also, perform the following:
A. Verify that the flow to the TOS is unrestricted
B. Open all valves in the inlet piping and clean coolant outlet. Verify
that the oil outlet valve is closed.
C. Position the Fluid Pick-up device in the tank. Depending upon the
application different fluid skimming devices are supplied.
The Static Pick-Up is a curved “J” pipe with a magnet to affix it in
one position on the tank. This pick-up is used where the tank
access is open and the coolant volume is constant.
Floating Skimmer Head: The floating skimmer pick-up is applied
where the volume of liquid in the sump is variable and sump
access is limited.
Affix the magnetic holder to the side of the tank and rotate the
floating-head so that it sits level on the tank.
Additional skimmer styles are available for specific applications.
The Freddy TOS is now ready for operation.

Normal Operating Procedures:
Before starting the unit check the free-oil level that has accumulated at the top of the
tank. It should be removed if the oil weir is not visible. To do this, open the oil
discharge valve, drain the oil into the oil tanks then close the oil discharge valve. The
height of the oil weir should be checked to ensure that coolant is not being discharged
with the oil. The discharge weir is set too low if coolant is being discharged into the oil
container. To raise or lower the oil weir use the tool provided and turn the weir
clockwise or counter-clockwise as indicated.
Check regularly to verify that the oil weir discharge pipe is not obstructed.
Start the pump and recheck the correct height of the suction pipe.
Maintenance Instructions:
Since there are only a few moving parts in the Freddy TOS, maintenance consists of
cleaning or changing the prefilters cartridges as necessary, periodic flushing of the
sediment which may accumulate in the bottom of the unit, , and (rarely) cleaning the
filter media if it becomes clogged with sediment.
The filter media can be cleaned by removing the basket and using a hose or power washer
on the media. (See Precautions below)
Daily: Check all hoses for damage and verify connections are tight. Drain the oil from
the tank if necessary. Check the prefilters and change (or clean) as required. On air
operated models check the lubricating oil level and refill if required. Empty the oil
storage tank(s) as required.
Feed Rate:
If there is a reduction in the feed rate from the pump it could be due to one of the
following:
The prefilter is plugged. Replace or clean.
The suction pipe on the float is set too high. Adjust as necessary
The suction line is blocked or split. Replace as required.
The pump has worn and needs service
Precautions:
Always fill the Freddy TOS with clean fluid before processing at the machine tool sump.
This avoids depleting the fluid volume in the sump.
DURING NORMAL USE, IT SHOULD NOT BE NECESSARY TO DRAIN THE
TOS OR REMOVE THE BASKET OF MEDIA. If you want to drain the TOS or
remove the media, you must first remove the floating oil layer on the top of the unit.

If the basket is removed through an oil layer or the unit is drained with free-oil on top of
the unit, then the media will need to be cleaned prior to reuse. To remove the oil layer,
close the oil outlet valve then close the discharge valve at the end of the discharge line.
Allow the level to rise in the media tank several inches above the oil discharge weir.
Observe this process to avoid overflowing the media tank which would cause liquid
to spill on the floor. Turn the unit off for 10 minutes allowing the oil to rise then open
the oil charge valve and allow all the fluid (oil and process fluid) to drain to the oil
storage container. After the level has drained back to the normal operating level you can
then remove the media basket.
A drain line at the bottom of the system allows for the removal of residual coolant or
wash water in the media tank.
Exceeding the rated flow to the Freddy TOS may affect the quantity of tramp oil the unit
can effectively remove.
If required, prime the electric pump by opening the valve at the bottom of the media tank
and filling the pump.
Disconnect the unit from the power supply in the event of a problem.
