SECTION 2. MAINTENANCE

 

 

 

 

2-1. INTRODUCTION

This section provides checkout and replacement procedures,

 

for various parts of the fryer. Before replacing any parts, refer

 

to the Troubleshooting Section to aid you in finding the cause

 

of the malfunction.

 

2-2. MAINTENANCE HINTS

1. A multimeter will help you to check electric components.

 

2. When the manual refers to the circuit being closed, the

 

multimeter should read zero unless otherwise noted.

 

3. When the manual refers to circuit being open, multimeter

 

should read infinity.

 

 

Do not move fryer with hot shortening in the frypot or

 

filter pan. Severe burns can result from splashing hot

 

shortening.

 

 

4. Remove weights from frame to easily access rear of fryer.

2-3. PREVENTIVE

To ensure a long life of fryers and their components, regular

2-4. HIGH TEMPERATURE This high temperature control is a safety, manual reset control,

LIMIT CONTROL which senses the temperature of the shortening. If the shortening 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, manually reset by pressing the red reset button. The red reset button is located under the control panel, in the front of the fryer, to the right of the drain. Once reset, the frypot starts heating.

Checkout

Before replacing a high temperature limit control, check to see that its circuit is closed.

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 inner heat shield.

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

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

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

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

2-4. HIGH TEMPERATURE

LIMIT CONTROL (Continued)

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

Replacement

1.If the tube is broken or cracked, the control will open, shutting off electrical power. The control cannot be reset.

2.Drain shortening from the frypot and discard. A substance in the tube could contaminate the shortening.

3.Remove control panel.

4.Loosen small inside screw nut on capillary tube.

5.Remove capillary bulb from bulb holder inside the frypot.

6.Straighten the capillary tube.

7.Remove larger outside nut that threads into pot wall, and remove defective control from control panel area.

8.Insert new control and replace screws.

9.Uncoil capillary line, starting at capillary tube, and insert through frypot wall.

To avoid electrical shock or other injury, run capillary line under and away from all electrical power wires and terminals. The tube must never be in such a position where it could accidentally touch the electrical power terminals.

10.Carefully bend the capillary tube as shown in photo and place into bulb brackets.

11.Pull excess capillary line from pot and tighten nut into frypot wall.

Be sure capillary bulb of high limit is positioned so it does not interfere with carrier or get damaged when cleaning frypot.

12.With excess capillary line pulled out, tighten smaller nut.

13.Replace inner and front panels.

14.Refill with shortening.

There are two fuse holders on each model of the electric fryers.

To check or change fuse, unscrew black fuse holder cap.

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

Checking Procedure for Fuse Holders

CONTROL PANEL FUSES 3 Phase

Remove the control panel and pull the wires from the fuse holder terminals. Using a multimeter or continuity light, check across the terminals. The circuit should be closed. If not, replace the fuse (HP# EF02-007) or fuse holder (HP# EF02-006).

Model 590/592

2-6. POWER/PUMP SWITCH The POWER/PUMP switch is a three way rocker switch with a center OFF position. With switch in the POWER position, the fryer operates. With switch in PUMP position, the filter pump operates, but the unit will not heat.

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

Checkout

1.Remove control panel.

2.Label and remove wires from the switch.

3.OFF position-should be open circuit anywhere on switch.

4.Power position. Check from:

5.Pump position. Check from:

#5 to #6 closed circuit #l to #2 closed circuit

#4 to #5 closed circuit #3 to #2 closed circuit

Check across the jumpers on the wires of POWER/PUMP switch. These jumpers have resistors and capacitors which may be faulty.

Replacement

1.With control panel removed, and wires off of the switch, push in on tabs on the switch to remove from the panel.

2.Replace with new switch, and reconnect wires to switch following the wiring diagram.

3.Replace the control panel.

The temperature probe relays actual shortening temperature to the control. If it becomes disabled, “E06” will show in the display. Also, if temperature is out of calibration more than 10°F, or 10°C, the temperature probe should be replaced. An Ohm check can be performed also. See chart at end of this section.

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.Drain the shortening from the frypot.

3.Remove the control panel.

4.Using a 1/2” wrench, remove the nut on compression fitting.

5.Remove the temperature probe from the frypot.

6.Place nut and new ferrule on new temperature probe and insert temperature probe into compression fitting until it extendsone-half(1/2)inch(1.3cm)intofrypot. Usetemperature probe gauge provided in temperature probe kit, to ensure proper placement in frypot. See Figures 2-1 & 2-2.

7.Tighten hand tight and then a half turn with wrench.

Model 590/592

Should the control panel become inoperative, follow these instructions for replacing the board.

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 two screws securing he control panel and lift panel up and out

3.Unplug the connectors going to the control board.

4.Install a new control panel.

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 splits and tears-replace if necessary

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

2-10. 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 lid upright, or severe injuries

 

could result. (See photo at left).

2-11. REVERSING THE LID

The gray rubber gasket surrounding the inside of the lid is de-

GASKET

signed to be reversed.

 

Because of heat expansion and the pressure used for cooking

 

process, gasket is constantly under extreme stress. Reversing

 

the lid gasket will help to assure 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 lid upright, or severe injuries

 

could result. (See photo in Tilting Lid Upright section)

3.

Clean the gasket and gasket seat with hot water.

4.

Rotate the gasket with the opposite side facing out.

 

Install the 4 corners of the lid gasket. Smooth gasket into

 

place, working from the corners towards the middle of each

 

side.

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

2.Using Phillips-head screwdriver, remove screws securing the top cap and remove cap.

3.Raise the lid.

4.Unscrew broken cable from the weight assembly and the 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 new cable into the weight assembly until tight.

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

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

9.Insert cable into the hole in the bracket and screw a 5/16” nutontoendofcable. Tighten cable, byscrewing thecable through this nut until the weight assembly becomes level.

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