2. ASSEMBLY AND OPERATION
2.1 Equipment Description
The Shortening Disposal Unit (SDU) is designed for the safe transportation of used shortening or
cooking oil from the kitchen to a disposal container. There are two sizes – the SDU 50 (holding up
to 50 lbs./23 kg) and the SDU 90 (holding up to 90 lbs./41 kg) of shortening. Both sizes are
identical in construction and operation except for the volume of shortening that can be handled. The
units consist of a tank to receive waste shortening/oil from a fryer and a heavy-duty manual pump
for transferring the shortening/oil to a disposal container. Both models are equipped with 7" (178
mm) wheels and foldable handles. The pump is mounted at a convenient height that allows it to be
operated from a standing position. The height of the discharge pipe allows pumping directly into a
standard 55-gallon drum.
The BKSDU is equipped with a 120VAC or 240VAC tank heater to prevent solid shortening from
solidifying prior to disposal. The BKSDU is equipped with a receptacle that accepts a three-prong,
grounded plug for protection against shock hazard. The power cord should be plugged directly into
a properly grounded, three-hole wall or floor receptacle. Do not cut off, remove, or otherwise
bypass the grounding prong on the power cord plug. CAUTION: Risk of fire and electric shock.
Replace only with manufacturer’s cord set, part number 8071224 for 120V or part number
106-4697 for 240V.

With the cover open, the top of the tank is 9¾ inches (248 mm) above the floor, permitting it to be
positioned directly beneath the drains of most fryers. (NOTE: The tanks on SDUs built before
January 2004 are 11½ inches (292 mm) high.). If using an SDU built before January 2004, the filter
pan cover on Frymaster PRO Series electric and gas fryers must be removed to allow the unit to be
positioned beneath the drain.
A variant of the SDU 50, the BKSDU is equipped with a 120V or 240V heater to prevent shortening
from solidifying in the reservoir.
2.2 Equipment Assembly
Assembly of the unit is a four-step process:
1. Remove the two bolts (or lock pins if manufactured prior to May 2006) from the handle-mounting
bracket and raise the handle to the upright position. Reinstall the bolts (or lock pins) in the bracket.
2. Ensure the O-rings and the bottom 2 inches of the suction tube are lubricated with Accrolube
with Teflon or an equivalent light oil or grease.
3. Turn the pump and suction tube upside down and carefully pour no more than one cup of
cooking oil down the tube. Rotate the pump handle slowly three or four times to prime the
pump.
4. Insert the suction tube through the pipe bracket on the handle and into the pickup tube on top of
the reservoir. Push down on the pump assembly and ensure the suction tube is fully seated.
2.3 Equipment Operation
WARNING
DO NOT use this unit to dispose of water or Boil-out solution. Introduction of water
or solvents into the unit will permanently damage the pump.
1. Turn the fryer off prior to draining into SDU. If so equipped, ensure the fryer drainpipe is firmly
threaded into the frypot drain valve.
2. Open the cover, verify that the crumb screen and rubber gasket on the inside cover are in place,
and position the unit so that the opening is directly under the frypot drainpipe.

DANGER
Before each use inspect the cover to ensure the cover gasket is present and
properly placed. DO NOT use the disposal unit if this gasket is damaged or
missing.
3. Slowly open the drain valve. Regulate flow with the drain valve to prevent splashing.
DANGER
DO NOT OVERFILL! Do not fill the reservoir above the fill lines on the sides of the
reservoir. Moving the SDU with an overfilled reservoir may result in spills and injury
to personnel who come in contact with the spilled shortening.
4. Carefully withdraw the unit far enough to allow the cover to be closed. Latch the cover in the
closed postion. Using the handle, carefully tip the unit back slightly for ease of handling and roll
the unit to the disposal site.
WARNING
DO NOT use the pump or discharge piping assembly as a handle!
DANGER
To minimize the potential for burns, shortening/oil must always be allowed to cool
below 100°F (38°C) before draining into the SDU and transporting to the disposal
area. However, DO NOT allow shortening to solidify in the SDU.
The unit is designed to be moved, when properly filled, at an average walking pace on a flat
surface. Care must be taken at all times when moving hot shortening or oil. Rough terrain or
sudden stops and starts may cause the contents of the reservoir to spill or splash out of the
reservoir, possibly causing serious injury to personnel. Always ensure that the cover is latched
shut when moving the unit.
5. At the disposal site, lift the pump assembly lock pin and rotate the discharge pipe as necessary to
position the discharge nipple over the opening of the disposal container. Release the lock pin to
secure the pump assembly in position. Turn the pump handle clockwise. The pump should start
discharging oil after a few turns. Continue turning the handle until the MSDU reservoir is empty.
NOTE: The pump is NOT self-priming. If it has not been used for several days, it may have lost
its prime and may need to be re-primed in accordance with Step 3 of Section 2.2.

6. On BKSDU units, the built-in heater may be connected to a grounded 120VAC or 240VAC
receptacle to prevent shortening from solidifying in the tank when immediate transfer to a
disposal container is not possible.
2.4 Cleaning
Clean the crumb screen with a solution of detergent and water. Clean the exterior surfaces of the
SDU with a soft cloth and a solution of detergent and water. It is not necessary to clean the interior
of the reservoir, but if desired it may be wiped down with clean paper towels to remove excess
residual shortening.
WARNING
DO NOT clean the interior of the reservoir with water or detergent. Introduction of
water or detergent into the unit will permanently damage the pump.
3. SERVICE PROCEDURES
3.1 Introduction
Other than routine cleaning and the replacement of worn suction tube O-rings, the SDU is
maintenance free. After long use, the pump vanes and pump shaft seal may require replacement due
to wear. Frymaster recommends worn pump vanes and/or pump shaft seals be replaced by an FASC,
but store personnel may perform these service actions without voiding the warranty.
3.2 Replacing Worn or Damaged O-Rings
If pump efficiency degrades, it is likely that the O-rings on the suction tube are worn or damaged.
To replace the O-rings, follow the steps below.
1. Lift the pump assembly straight up and out of the handle assembly.
2. Remove the worn or damaged O-rings from the grooves at the bottom of the suction tube and
replace with new O-rings. Apply Accrolube with Teflon grease or equivalent to bottom 2 inches
of the suction tube.
3. Insert the suction tube through the tube bracket in the handle and into the receiver on top of the
reservoir. Push down on the pump assembly to make sure the suction tube is fully seated.
3.3 Replacing Worn Pump Vanes and/or Pump Shaft Seal
Depending upon the amount of use, the vanes in the pump assembly will eventually wear, reducing
the efficiency of the pump. The pump shaft seal can also become worn and start to leak. A kit for
replacing the vanes and the seal is available. The pump shaft seal can also be purchased as a
separate item. To replace the pump vanes, and/or the pump shaft seal, follow the steps below (refer
also to the illustration on Page 6).
1. Loosen the setscrew securing the pump handle to the pump shaft and slip the handle off the shaft.
If unit is a BKSDU remove the eight screws that secure the pump cover in place and remove the
cover.

6
2. Remove the five screws securing the front cover and remove the cover.
If replacing the pump shaft seal only, remove the old seal and install the replacement as shown in
the illustration below, then go to Step 5.
If replacing the pump vanes, go to Step 3.
3. Grasp the pump shaft and carefully pull the rotor assembly straight out of the pump housing far
enough to expose the vanes. IMPORTANT: The vanes are spring-loaded. Use one hand to
hold the vanes while pulling the rotor assembly the rest of the way out of the housing. Carefully
release the vanes and discard the worn vanes, springs, and rods.
Step 5 - Replace gasket.
Step 1 - Loosen
setscrew and
remove handle.
Step 2 - Remove cover
screws and cover.
Step 3 - Grasp
shaft and pull
rotor assembly
out of housing.
Step 4 - Replace
vanes, spring,
and rod.
Pump shaft seal fits into the
recess of the pump cover.
4. Assemble the replacement vanes, spring and rod into the rotor assembly. Compress the vane
spring and carefully insert the rotor assembly back into the pump housing.
5. Position the replacement gasket on the pump body, slip the cover over the shaft, and align the
pins in the cover with the holes in the pump housing. Reinstall the five screws removed in Step
2 and tighten securely (torque to approximately 60 inch-pounds).
6. Slip the pump handle back onto the shaft and align the screw hole in the handle with the screw
hole in the shaft. Tighten the setscrew loosened in Step 1 securely.
