2-4. HIGH TEMPERATURE

 

LIMIT CONTROL

This high temperature control is a safety, manual reset control,

 

which senses the temperature of the shortening. If the shorten-

 

ing temperature exceeds 425°F (218°C), this switch opens and

 

shuts off the heat to the frypot. When the temperature of the

 

shortening drops to a safe operation limit (15-20 minutes),

 

manually reset by pressing the red reset button. The red reset

 

button is located under the control panel, in the front of the

 

fryer. Once reset, the frypot starts heating.

 

Before replacing a high temperature limit control, check to see

 

that its circuit is closed.

Checkout

The shortening temperature must be below 380°F (193°C) to accurately perform this check.

1.Remove electrical power supplied to the fryer.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.

2.Remove the control panel.

3.Remove the two nuts securing high limit bracket to the unit, and pull the bracket from the unit.

4.Remove the two screws securing the high limit to bracket, and remove the high limit from the bracket.

5.Remove the two electrical wires from the high temperature limit control.

6.Manually reset the control, then check for continuity between the two terminals after resetting the control. If the circuit is open, replace the control, then continue with this procedure. (If the circuit is closed, the high limit is not defective. Reconnect the two electrical wires.)

2-8. PRESSURE REGULATION The Henny Penny Fryer uses pressure as one of the components of the cooking process. Once the lid is sealed to the frypot and the solenoid valve closes, a deadweight valve maintains the correct pressure in the frypot.

The lid has minimal and limited maintenance and repair procedures, which are addressed in the following sections.

The following is a routine maintenance schedule for the lid:

Every 90 days

Clean and reverse the lid gasket.

Yearly Inspection

Check lid gasket for splitting and tears - replace if neces sary.

Check pressure pads for wear - rotate if necessary.

Check cam slide guides - replace if worn or broken.

Check lid rollers - replace if cracked or damaged.

2-9. TILTING THE LID

The lid assembly is easily tilted up for cleaning or servicing.

UPRIGHT

 

1.Raise the lid and remove racks and carrier.

2.Grasping the lid handle, lift the front of the lid up until it stops in an upright position.

Be sure the metal arm on the left side of the lid is in the vertical position holding the lid upright, or severe injuries could result. (See photo at left.)

1002

2-7

2-10. REVERSING THE LID

The gray rubber gasket surrounding the inside of the lid is

GASKET

designed to be reversed.

 

 

Because of heat expansion and the pressure used for the cook

 

ing process, the gasket is constantly under extreme stress.

 

Reversing the lid gasket will help to ensure that the fryer will

 

not lose pressure through leakage.

 

 

1.

Put the lid in the upright position, as previously described.

 

2.

Using a thin blade screwdriver, pry out the gasket at the

 

 

corners. Remove the gasket.

 

 

 

Check the gasket for any tears or nicks. If the gasket is

 

 

damaged, it needs to be replaced.

 

 

 

Be sure the metal arm on the left side of the lid is in the

 

 

vertical position holding the lid upright, or severe

 

 

injuries could result. (See photo on page 2-7.)

 

 

3.

Clean the gasket and gasket seat with hot water.

 

 

4.

Rotate the gasket with the opposite side facing out.

 

 

Install the four corners of the lid gasket. Smooth the gasket

 

 

into place, working from the corners towards the middle of

 

 

each

side.

2-11. LID COUNTERWEIGHT The Lid Counterweight in the back of the fryer balances the CABLES weight of the lid system to allow easier opening and closing of

the lid. The weight has two cables attached to it, and weighs about 150 lbs. (67.5 Kg).

1.Using a 3/8” socket, remove the nuts securing the rear shroud of the fryer and remove the shroud.

2.Using Phillip’s-head screwdriver, remove screws securing the top cap and remove cap.

3.Raise the lid.

4.Unscrew the broken cable from the weight assembly and bracket attached to the fryer, and remove broken cable.

5.Screw a 5/16” nut on each end of the new cable.

6.Using a wrench, screw the new cable into the weight assembly until tight.

7.Using a 1/2” wrench, tighten nut (already threaded on the cable) against the weight assembly, securing the cable into

weight assembly.

8. Pull the cable over the pulley and down behind the weight assembly .

9.Insert the cable into the hole in bracket and screw a 5/16” nut onto end of the cable. Tighten cable, by screwing the cable through this nut until the weight assembly

becomes level.

The safety cable should now have slack in it with the weight assembly level.

10.Tighten the nut against the top of the bracket, securing the cable.

11.Replace top cap and rear shroud; repair is now complete.

6.Install new pad in reverse order.

2-10

1002

2-13. LID ADJUSTMENT

If steam leaks out from around the lid gasket, the pressure pads

 

could be worn or broken. If the pressure pad is worn, but not

 

broken, it can be reversed 180 degrees, and the other end of the

 

pad used. See Section 2-12.

 

If steam leaks, check for:

• Pressure pad wear

• Cracked or worn gasket

• Gasket installed improperly

• Fryer operating above 12 psi (827 mbar)

Fryer should be operating at 12 psi (827 mbar), or serious burns could result.

2-14. CLEAN THE NYLATRONS 1. Spray Henny Penny biodegradable, food safe, foaming degreaser (part no. 12226) on Nylatrons.

2.Raise lid up and down several times to spread degreaser.

3.Wipe Nylatrons to remove food soil, grease, and degreaser residue.

2-15. SOLENOID VALVE

This is an electromechanical device that causes pressure to be

 

held in the frypot. The solenoid valve closes at the beginning

 

of the cook cycle and opens automatically at the end of the

 

cook cycle. If this valve should become dirty, or the Tef on

 

seat nicked, pressure will not build up. The gas fryer uses a

 

120 volt, 60 Hz coil (208/240 volt, 50 Hertz internationally).

To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.

Coil Check Procedure

Remove the solenoid wires from the wire nuts which are found behind the control panel. Check across wires.
