Griddle Thermostats
Griddles are equipped with snap action thermostats. Field
recalibration is seldom necessary and should not be resorted
to unless experience with cooking results definitely provides
that the control is not maintaining the temperature to which
the dial is set.
Calibration Instructions
1. Use a test instrument (pyrometer) with special disc type
thermocouple or reliable “Surface” type thermometer.
(Note: A drop of oil on the face of the disc will provide
better contact.)
2. Turn all griddle temperature control dials to 350°F
(177°C). In order to allow griddle temperature to stabilize,
the controls must be allowed to cycle twice before taking
a test reading.
3. Check temperature reading when the control just cycles
‘OFF’ (as indicated by the cycling amber pilot) by placing
the sensor firmly on the griddle surface, directly above
the sensing bulb control. If the temperature does not
read with in 15°F (8°C) of the dial setting, recalibrate as
follows:
4. Carefully remove the thermostat dial, not disturbing the
dial setting.
5. Hold the dial shaft steady and with a screw driver,
turn the calibration screw located inside the dial shaft,
clockwise to decrease and counter-clockwise to increase
the temperature.
EG: 1/4 turn = 35°F (19.5°C)
6. Replace the thermostat dial and repeat steps 1 through 3
to verify the correct adjustment has been made.
Sandwich Griddle – Model E22-18SG
Serial Plate Location
The serial plate is located on right grease drawer slide, to
access by remove the grease drawer.
Wall Clearances
Do not install closer to a wall of combustible material than:
Sides 1” (25mm)
Back 1-1/2” (38mm)
Electrical Connections
For supply connection, use wire suitable for 90°C (194°F).
Refer to griddle section for electrical connection, griddle
thermostats and calibration instructions.
Controls
The switch on the left of the unit is an infinite switch used in
conjunction with an amber pilot light, used for heating the
top griddle plate.
The control on the right of the unit is a thermostat used in
conjunction with an amber pilot light, used for controlling
temperature of the lower griddle plate.
NOTE: The top griddle is inoperative until the thermostat
control is set to a desired temperature.
To Adjust The Tension On The Top Griddle Plate
Disconnect unit by removing the fuse or tripping circuit
breaker in the service panel. The tension adjusting bolt is
located underneath the lower griddle pate at the inside
rear of the unit. Raise the lower griddle and slide forward
carefully. This will allow access for adjustment of the bolt.
Turn the bolt clockwise to increase tension and counter-
clockwise to decrease tension.
Food Warmers – Model E22-15W,
E22-15WP, E24-32W & E24-32WP
Serial Plate Location
The serial plate is location on the main front.
Wall Clearances
Do not install closer to a wall of combustible material than:
Sides 1” (25mm)
Back 1” (25mm)
Electrical Connections
For supply connection, use wire suitable for 90°C (194°F)
Electric connection may be made though the knockout at
the rear of the unit to the terminal block located behind the
lower front panel. Access to the terminal block is gained by
removing the infinite switch dial, two lower front panel acorn
nuts and front panel.
