GENERAL
INTRODUCTION
This Service Manual covers specific service
information related to the models listed on the front
cover. ERA and EBD series electric fryers come
equipped with behind-the-door solid state controls.
The features and operation of the cooking controls are
the same for both single floor model fryers and
Kleenscreen battery fryers. All pictures and
illustrations are of a 2ER50AF (17kW, 208V) unless
otherwise noted.
SINGLE FLOOR MODEL FRYERS
Fryers with the Filter-Ready option installed, use the
Mobile Filter. For service information related to the
Mobile filter refer to F24599 MOBILE FILTERS. A
GRO Frymate (dump station) can be configured in a

KLEENSCREEN FILTRATION
SYSTEM
The Kleenscreen filtration system is integrated into the
ERA & EBD Series fryer battery. The filter is housed
in a pull-out drawer assembly at the base of the fryer.
The filtering components in the drawer include a
stainless steel filter tank, crumb-catch basket and a
dual element mesh filter screen. With the filter drawer
closed, a self-seating oil return line provides the path
to return the filtered shortening to the fry tank.
This system is designed to provide a thorough and
easy method to filter the shortening.
Some of the benefits include:
• Self-contained system eliminating the use of
external filter equipment.
• Paperless filtering system.
• Easy to clean and low maintenance.
Kleenscreen fryer batteries are available in a
minimum of two and a maximum of four fryer sections.
The fryer size of each section is identical.
A GRO Frymate (dump station) can also be included
as one or more of the sections.

ELECTRICAL OPERATION
COMPONENT FUNCTION
FRYER CONTROLS
Cooking Control
Monitors and evaluates input signals to the control:
Activates heat output signal to maintain shortening
temperature; and activates filter output signal to power
the fill solenoid valve.
Transformer
Supplies 24VAC to the cooking control circuit.
Transformer is energized when power switch is turned
on.
Power Switch Supplies power to control circuit for fryer operation and
filtering.
Melt Select Switch Controls heating circuit operation during melt cycle based
on type of shortening being used (liquid/ solid).
High Limit Thermostat Prevents the shortening from reaching temperatures
over 450°F (manual reset).
Temperature Probe
Senses temperature of shortening. Converts the
temperature into a resistance which is monitored by the
cooking control. The probe is an RTD (resistance
temperature device) of the Thermistor type. As
temperature increases the resistance value decreases.
Drain Valve Interlock Switch (DVI)
A magnetic reed switch mounted on the manual drain
valve that supplies a drain valve position signal (open/
closed) to the cooking control. When drain valve is open,
the drain interlock input to the control is removed
(magnetic reed switch contacts open). This prevents
heating elements from being energized with the fry tank
empty.
Tilt Switch
A magnetic reed switch (N.O.) mounted underneath the
element head assembly. Remove power from 1CON and
3CON to de-energize the heating elements when the
elements are raised.
1CON, 3CON and 2CON, 4CON Contactors Supplies line voltage to heating elements.
Heating Elements Produces heat that is transferred to the shortening.
R1 Heat Relay Supplies power to 2CON and 4CON contactor coils.
R2 Power Relay Supplies power to cooking control.
KLEENSCREEN FILTER CONTROLS
Fill Solenoid Valve When energized by filter switch, the solenoid valve opens
to allow the flow of shortening thru filtering system.
Pump Motor Operates pump to circulate shortening through filtering
system.

KLEENSCREEN FILTER CONTROLS
Start Switch
Supplies start heating function to the temperature control
at the beginning of a cooking cycle or after the vat has
been filled from the filter process.
Filter Switch
Energizes pump motor to filter the shortening when
switch is closed (valve handle extended). Filter power
switch must be turned on.
Discard Valve Switch
A magnetic reed switch mounted on the mechanical
discard valve that closes when discard valve handle is
extended to discard the shortening. Prevents R4 solenoid
relay N.C. contacts from suppling power to the fill
solenoid valve when filter key is pressed.
R3 Filter Relay Supplies power to pump motor and solenoid.
R4 Solenoid Relay Removes power to solenoid if discard valve switch is
operated.

• Fryer connected to correct supply voltage
and is properly grounded. Separate
connections are required for each section of
the battery.
• 120/24VAC transformer energized.
• Internal fryer circuit breaker ON (24kW,
208-240V units only).
• Power switch off.
• Shortening at proper level in fry tank and
below last set point temperature used.
• Cooking control is setup properly and ready
to use.
• Manual drain valve closed (drain valve
interlock switch N.O. is closed).
• Tilt switch contacts closed (N.O. - held
closed with heating elements lowered).
• High limit thermostat closed.
2. Turn power switch on. Supply voltage energizes:
• 1CON and 3CON thru high limit thermostat
and tilt switch.
• R2 power relay coil and R2 N.O. contacts
close.
• Cooking control thru DVI switch.
3. Press start momentary switch. If shortening
temperature is below set point:
A. J5 outputs 24VDC to R1 thru wire 56.
B. R1 heat relay coil energized and R1 N.O.
contacts close.
C. 2CON and 4CON are energized and heating
elements are powered.
4. Shortening reaches set temperature.
A. Cooking control de-activates the heat
demand output (24VDC) at J5.
B. With power removed from J5, R1 is de-
energized thru wire 56.
C. 2CON and 4CON are de-energized and
power is removed from heating elements.
5. Cooking control cycles heat output on shortening
temperature until power switch is turned off,
heating elements are raised or a high limit
condition occurs.
A. If shortening reaches 460°F
• Tthe high limit thermostat opens
• 1CON and 3CON are de-energized
• Power is removed from heating
elements.
B. 1CON and 3CON remain deenergized until:
• Shortening temperature drops below
460°F.
• Manual reset button is pressed.
• Start button is actuated.
Filtering System
The discard valve handle is connected to a
mechanical valve and switch assembly to route the
flow of shortening (electrically and mechanically) in
the filtering system.
Refer to Installation & Operation manual for specific
instructions on filtering.
ERA / EBD ELECTRIC FRYER - ELECTRICAL OPERATION
F25385 (1220) Page 20 of 49
1. Conditions
• Fryer connected to correct supply voltage
and is properly grounded.
• Power switch to the fryer section off.
• Shortening between 300°F and 350°F.
• Filter drawer assembly installed properly.
• Filter power switch off.
• Discard valve handle (yellow) retracted.
• Discard valve switch N.O. contacts open.
• Mechanical discard valve closed.
2. Turn power switch on, to the fryer section to be
filtered.
NOTE: Shortening should not be filtered outside of
this temperature range. At lower temperatures the
shortening is thicker which may increase filtering time
and place a greater load on the pump. At higher
shortening temperatures, the pump seal life is
decreased.
3. Set cooking control between 300°F (minimum)
and 350°F (maximum).
NOTE: If using solid shortening, once it has melted,
stir the shortening to eliminate any solid shortening in
cold zone of the fry tank.
4. Allow shortening to cycle at set temperature for
approximately 10 minutes.
NOTE: If using solid shortening, allow hot shortening
to stand in filter tank for approximately 6 minutes prior
to filtering.
5. Open the manual drain valve to the fryer section
