Shortening Recirculation System Installation
PITCO LJ-FBG Frying System
The Shortening Recirculation System directs cleaned shortening from the filter pan, through the fryer drain,
back to the filter pan. This allows the required 10-minute filter cycle to run at the same time that frypot is being
cleaned. It is estimated to take 3-4 hours to install. For installation help, please call 603 225-6684 Service/Parts

electric cord(s).
B. Working on the fryer with the pump, Cut white glass tape holding heat tape
from pump to frypot return valve.
C. Disconnect pump flex hose flare fitting from the frypot return valve.
D. Remove bolts holding BACK end of filter pan guid e rail ( see fig.3)
Return to the front of the fryer:

5. REMOVE PUMP:
5.A
5.B
5.C
Pan guide rail
Fig 3
Remove filter pan socket, and
retaining bracket from pump support
rods.
NOTES REGARDING PUMP REMOVAL:
1. Some rotation of the pump assembly to the right as it is lowered will allow discharge hose to pass around internal
gas hoses.
2. 2. Pump assembly is heavy, support it adequately while pulling rods out to protect yourself and the pump. Use
care when lowering the pump to prevent damage to the flexible gas line for fryer control valve
6. CONVERSION OF FILTER PUMP DISCHARGE PIPING:
1. Cut away white glass tape holding
heat tape to pump flex hose.
2. Remove flare elbow from outer
end of braided flex hose.
3. Remove braided flex hose, (to be
reinstalled in step 5) outer elbow and
short pipe from pump discharge.
4. Remove the outer elbow and 2”
nipple. LEAVE REMAINING
ELBOW IN PUMP.
Support pump assembly with hand
as shown while removing pump
support rods with other hand.
Fig 4: Pump after discharge piping
converted. Reapply heat tape to flex
hose when finished re-piping pump
outlet.
Lower pump assembly out of
cabinet, motor end first.
5. Clean threads on flex hose, apply
high temp Fluropolymer thread
sealer, and insert threaded end of
flex hose into elbow remaining in
pump discharge port. See Fig 4
6. Re-attach heat tape to hose with
white tape provided.
NOTE: Heat rises. Always apply
heat tape so it’s positioned under
the oil line in it’s “installed
position”.

7. CHANGE DRAIN LINE “T” FITTING:
1.
PITCO LJ-FBG Frying System
2.
Use a 7/16” deep socket to loosen drain line clamp
and slide both the clamp and red gasket to left.
3.
Use a screwdriver as a wedge between drain T and
upper flange to separate them from the drain valve.
5.
The new drain fitting is put in with hose end towards
REAR of fryer.
9.
Remove bolts holding drain T to the flange on drain
valve.
4.
Pull the drain piping out around the drain valve and
slide the Drain T out of the drain line socket.
6. Install new drain “T” by reversing steps 1-4.
7. Check that drain “T” and drain line looks straight as it
runs from left to right. Adjust if needed.
8. Tighten flange bolts so that drain line is straight and
flanges stay parallel to each other.
NOTE: Wipe ALL shortening from drain tubes parts
before installing red gasket. Leaving a film of
shortening on tube parts may allow gasket to slip off
over time.
NOTE: Be certain to reinstall thread cap on clamp
tensioning bolt to protect operators!
Install a new drain line gasket, reattach clamp, and
install thread cap on clamp bolt.

8. INSTALL RECIRCULATION VALVE ASSEMBLY:
1.
2.
3.
1. Attach mounting bracket to the
recirculation valve assembly with #
10 x3/8” screws (fig1 item 12). Leave
screws loose.
3.
Hold valve assembly straight, attach
support bracket to cabinet with driller
screws (item12).
4.A
This hose creates a drainage trap
(white line) that will allow shortening
to harden in line. See step 5
Attach flare connection between flex
hose and valve assembly.
Leave joint hand tight for now.
3.A
Support bracket -installed view.
Holes in bracket create a drilling
guide for attaching to cabinet.
5.
NOTE: If trap is present figure 5,
Refer to Fig 2, note 2 to correct
trap before proceeding to step 6.
It may be necessary to remove the
valve assembly from the fryer to
change to the 3 ½”x ½” pipe.
Attach elbow from valve assembly to
fryer valve hand tight.
4.
Check hose is not creating drainage
trap (white line). This hose will allow
piping to drain.
6.
Tighten all flare fittings. Support hose
as shown while tightening.
Tighten screws holding valve
assembly to support bracket
