OPERATION AND CARE OF

FRYER FILTER-IN-A-DRAWER

SAVE THESE INSTRUCTIONS

GENERAL

The Fryer Filter-In-A-Drawer filters the oil as it is pumped back to its respective tank. Valves inside the
doors under each fry tank must be set so only one tank is being drained, filtered and pumped back at
any one time.

The Fryer Filter-In-A-Drawer is used on the following Hobart Fryer Models:

Gas Fryers Electric Fryers

HG35F HGD35F HGC35F HFD40F HFC40F
HG45F HGD45F HGC45F HFD50F HFC50F
HG65F HGD65F HGC65F HFD85F HFC85F
HG85F HGD85F HGC85F HD225F HC225F

ASSEMBLY

1. After unpacking, wash the filter tank, crumb basket and filter screen. Use dishwashing
detergent and warm water, or clean the components in a dishwasher. Rinse the filter tank,
crumb basket and filter screen thoroughly. Wipe components dry with a clean cloth.

2. Pull the filter drawer out.

3. Place the filter tank in the filter drawer. Hang the crumb basket from the left tank handle inside
the filter tank (Figs. 1 and 2). Position the filter screen assembly flat on the bottom of the filter
tank so the filter orifice underneath the screen fits the suction hole in the bottom of the tank (Figs.
1 and 2). Close the drawer.

4. Make sure the two O-Rings are in place inside the filter suction port (Figs. 1 and 2). As the
drawer is closed, make sure the filter suction connector fits tightly into the filter suction port
(Figs. 1 and 2).

OPERATION

WARNING: HOT FRYING COMPOUND AND PARTS CAN CAUSE BURNS. USE CARE WHEN

OPERATING, CLEANING OR SERVICING THE FRYER. USE CARE WHEN FILTERING. DO NOT
LEAVE UNATTENDED.

WARNING: SPILLING HOT FRYING COMPOUND CAN CAUSE SEVERE BURNS. DO NOT
MOVE THE FRYER WITHOUT DRAINING ALL FRYING COMPOUND FROM THE TANK.

FILTERING PROCEDURE WHEN USING LIQUID SHORTENING

1. Turn the fryer's power OFF and open the doors (Fig. 3).

NOTE: HGC and HGD models have a drain valve interlock
system built in that will automatically shut the fryer off as soon
as the drain valve is opened.

2. Slowly turn the red fryer tank drain lever counterclockwise
(Fig. 5) until it stops. This allows the oil to drain into the filter
tank.

NOTE: Drain and filter only one fryer tank at a time.

Fig. 3

3. Pull the filter drawer out. Lift the filter tank cover up (Fig. 4). Make sure filter tank and parts are
properly assembled (pages 3 through 5).

4. Add 8 ounces of diatomaceous earth to the filter tank. Agitate to mix the diatomaceous earth
and shortening. Replace the filter tank cover. Slide the filter drawer back into place.

shortening to stand in the filter tank for
approximately 6 to 10 minutes. Then proceed
with steps 4 through 10 under Filtering
Procedure when Using Liquid Shortening on
pages 6 and 7.

FILTERING TIPS

• If filtering at the end of the day, make sure all the oil is returned to the fryer tank.

• Open the filter drawer approximately 1" to allow any oil in the return line to run back into the filter
tank. This will take about 30 seconds to complete.

• Close the filter drawer. If solid shortening is used, follow the "Melt" procedure the next morning.

PERIODICALLY REMOVE EXCESS DEBRIS FROM THE FILTER

The following operation is required after filtering one or more batches, as needed:

1. Pull the filter drawer out and remove the filter tank cover from the filter tank.

2. Remove the crumb basket and empty any debris into the trash.

3. Remove the filter screen assembly.

4. Scrape debris from the bottom of the filter tank and from the screen assembly into the trash.

NOTE: Scrape debris away from suction hole to avoid compacting debris in hole.

5. Reinstall the filter screen assembly and crumb basket.

6. Replace the filter tank cover. Close the drawer.

FLUSH AND DISCARD

1. Turn the fryer power OFF.

2. Make sure filter tank and parts are properly assembled
(pages 3 through 5). Open the fryer tank drain lever (Fig.

11) of the fryer tank that holds oil that is to be discarded.

CLEANING THE FILTER DRAWER

1. Pull the filter drawer out and remove the filter tank cover.

2. After filter parts have cooled, lift the filter tank out of the
drawer (Fig. 16). Set the filter tank aside.

3. Lift the drawer from the drawer slides (Fig. 17) and set
the drawer aside.

4. Lift the drawer slides up and off the slide guides (Fig. 18).

5. Carry the parts to the sink area for cleaning.

6. Remove the crumb basket from the filter tank.

7. Remove and disassemble the filter screen assembly for
cleaning (Fig. 19). The top left side of the assembly has
a metal latch and bar. Slide the metal latch off the bar. Lift
the bar up to allow access to the internal filter.

NOTE: The filter screen assembly should be cleaned daily. The
filter screen assembly parts may be placed in a dishwasher or
cleaned using a sink spraydown hose with dish detergent.
However, periodic fryer boil-out cleaning is recommended to
remove thick grease residue on the filter screen assembly. This
residue may hinder the filtration process. If you notice that the oil
filter return time is taking longer than 4 minutes to complete the
filter cycle, boil-out of the screen assembly is recommended.
This can be performed as part of the normal fry tank boil-out
procedure (see Fryer Boil-Out Instructions on page 11).

8. Wash all parts of the filter, including the drawer and
drawer guides, in normal dishwashing detergent. All
parts are dishwasher-safe and can be cleaned in a
commercial dishwasher instead of by hand.

Fig. 16

Fig. 17

Fig. 18

9. Rinse parts thoroughly and wipe dry with a clean cloth.
All parts must be completely dried before reuse.

10. Reinstall all removed filter parts before operating the filter
system.

11. The top cover must be replaced before operating this
system.

FRYER BOIL-OUT INSTRUCTIONS

CAUTION: Do not run water or boil-out solution through the filter motor or pump. Do not use
the filter during boil-out or cleaning of the fryer.

Before cleaning the fryer, read the entire cleaning instructions provided by the cleaning product's
manufacturer. Some cleaners will require a boil-out procedure at boiling temperature, and some will not.
If your cleaning product company calls for a boil-out procedure, follow their procedures after performing
steps 1 through 5. If boil-out is required, but no procedures are stated, follow steps 1 through 23.

1. Turn off the fryer that is to be boiled out.

2. Remove and set aside the filter drawer assembly.

3. Drain all shortening from the fryer to be boiled out. Drain old shortening into a suitable disposal
container and discard.

4. Remove the filter screen assembly from the filter drawer vessel and separate the screen into
two parts (see page 10).

5. Place the two separated parts of the screen assembly into the fryer tank that is to be boiled out.

6. Following the cleaning instructions on page 10, clean the remaining
drawer assembly parts.

7. Place a stock pot under the drain manifold opening (Fig. 20).

8. Close the drain valve and fill the fryer tank with hot water to the

- Max - fill line.

9. Set the fryer thermostat to 210°F to 225°F (99°C to 107°C) and
turn the fryer on.

10. Allow water to come to a slow boil.

Fig. 20

PL-41623

11. Add boil-out solution and mix thoroughly. The water in the fryer tank must be near boiling for
the boil-out solution to dissolve completely and achieve maximum benefit.

CAUTION: Adding boil-out solution to boiling water can cause the fryer to boil over.

12. Allow the fryer to simmer or slowly boil for 10 to 15 minutes. Watch the fryer to make sure it does
not boil over. During the boil-out process, scrub the tank using the cleaning brush provided with
the fryer. To avoid damage to the tank finish, do not use a metal brush or scouring pad.

13. Turn the fryer off and allow the boil-out solution to remain in the fry
tank for another 10 to 15 minutes. The hot boil-out solution will
continue to break down oil residue at water temperatures as low as
180°F (82°C).

14. Open the drain valve.

15. Drain the boil-out compound into the stock pot below the drain
manifold opening (Fig. 21). Monitor the contents of the stock pot.

PL-41625

The full content of the fryer tank may not fit into the stock pot. If not,
close the drain valve when the stock pot is almost full and discard

Fig. 21

the boil-out solution.

16. Replace the emptied stock pot below the drain manifold opening, and repeat steps 14 and 15
as many times as needed.

17. Close the drain valve and fill the tank with clean, hot water to the - Max - fill line; drain and discard
as in steps 14 and 15.

–11 –

18. After rinsing the tank, close the drain valve and refill the tank with hot water to the - Max - fill line.

19. Add 1 cup (0.2 L) of vinegar per 20 lb (9 kg) of fryer capacity to neutralize any caustic ingredients
remaining from the boil-out solution.

20. Turn the fryer on and slow boil for a few minutes with the thermostat set at 210°F to 225°F (99°C
to 107°C).

21. Turn the fryer off and drain the tank (see steps 14 and 15).

22. Close the drain valve and rinse the tank again with hot water.

23. Drain fryer tank (see steps 14 and 15) and remove. Dry and reassemble the filter screen
assembly. Thoroughly dry the fryer tank. Close the drain valve. Reinstall the entire filter drawer
assembly to the fryer. Fill the tank to the - Min - fill line with fresh oil or shortening.

TROUBLESHOOTING

NOTE: If using solid shortening, after all filtered oil has been returned to the fryer tank and the filter

power switch is off, open the filter drawer approximately 1 inch. This allows the remaining shortening
in the line to drain into the filter tank to prevent possible clogging as the shortening cools and solidifies.
