EQUIPMENT SET-UP, CALIBRATION,
CLEANING AND CLOSE PROCEDURES
Set-up
IMPORTANT: Clean out any remaining water from filter
machine bowl.
1. Place the screen, with its thread facing up, inside the
filtering bowl. See figure 1.
2. Place filter paper (manufactured to McDonalds
specifications) over the threads and on top of the
screen. Be sure the hole in the paper is centered to
fit over the shoulder so the paper will lay flat. See
figure 2.
3. Screw on the standpipe. Tighten by hand. See figure
3.
4. Place the ring weight on the filter paper. Make sure
paper is not folded or creased under the ring. See
figure 4.
5. Center safety grid over standpipe. This will allow the
grid to suspend over the rim of the filtering bowl. See
figure 5.
6. Set the motor on the edge of bowl and screw the union
to the standpipe by hand. Make sure the connection
is hand tight. See figure 6.

7. Place the anti-splash tube on filter bowl by doing the
following:
A. Grasp tube by handle.
B. Hook prongs under lip of bowl.
C. Rotate downward until tube rest is against the
shortening filter bowl.
The anti-splash tube has 2 ends. One end has a
diffuser plate attached inside the tube, and the
opposite end is open. Hook the tube over the filtering
bowl rim so that the end with the diffuser is closest to
the safety grid.
8. Attach hose to pump. Make sure the connection is
hand tight. Put the nozzle in its holder.
CAUTION: This hose is made to bend up to a
radius of six inches (15.2 cm). If the hose is
bent under six inches (15.2 cm) or if the hose
is crimped, it could crack, causing it to leak
hot oil which may cause burns. If the hose is
cracked and/or leaking, do not use until it
has been replaced or repaired.
When finished filtering each vat, roll the unit to the next
vat by using the handle attached to the motor and pump
assembly.
CAUTION: Do not pull the unit by the power
cord or the hose.
OPERATING INSTRUCTIONS
Refer to your McDonald’s Operations and
Training Manual for the proper procedures to
filter your Fry Vats. If your manual does not
contain this procedure, contact your Regional
Training Department.
Close
After the filtering, the filter must be cleaned and stored
so that it will be ready for next use. Follow these
cleaning procedures:
CAUTION: Parts are hot. Handle with care,
and use filter shortening gloves.
1. Unplug the power cord. Return the filtering machine
to the back sink to disassemble.
2. IMMEDIATELY disconnect the hose from the pump
and drain the shortening from the hose into the bowl.
3. Unscrew the pump from the standpipe and lift the
motor assembly from the bowl.
4. Remove the safety grid, ring weight, anti-splash tube,
and place them in the back sink. Unscrew the
standpipe assembly from the screen assembly and
place in the back sink.
5. Remove and discard filter paper.
7. Discard any shortening left in the bowl into the
shortening disposal cart/shortening drum.
8. Wash the ring weight, standpipe, screen and bowl
with the hottest water possible and fryer cleanser to
prevent carbon buildup. (Do not use APC.)
9. Wipe dry with a clean towel.
10. Wipe the motor assembly and filter hose using a
clean towel.
11. Reassemble bowl, filter screen and ring weight.
Place the standpipe assembly, and filter hose inside
the bowl.
12. Roll filtering equipment into storage location.
CAUTION: Do not store motor and pump
assembly on the screen assembly. This
could cause the screen to warp, tear away
from the welds or cause grease to damage
the power cord and motor.
CAUTION: Do not pump water through the
motor and pump assembly. This will cause
the pump gears to rust and void the war-
ranty.

PROBABLE CAUSEPROBLEM CORRECTIVE ACTION

SEALING PROCEDURE:
Sprinkle 5 oz. (142 g) of Gycor (HCS) around the edge of
the ring weight. Drain the vat and re-circulate the short-
ening. This process should “seal” air leaks around the
ring.
CAUTION: Use this procedure only when a leak
occurs and all shortening cannot be drained. Using
excess Gycor (HCS) can cause the machine to clog
during filtering of last vats. THIS SHOULD ONLY BE
AN INTERIM PROCEDURE UNTIL EQUIPMENT CAN
BE REPAIRED OR REPLACED.
