Garland E20 SERIES ELECTRIC UNITS - Manuel (Page 8)

Part # P66 (01/25/08) Page 8
Controls
Infinite switches are used to control the heating units:
Hi to 5 High heat
5 to 3 Medium heat
3 to Lo Low heat
Setting of switches between the numbers will give
intermediate heat. Switches are reversible and may be
turned right or left.
Product Application
Food warmer may be used as a wet type or dry type. If used
as a wet type, fill heat well with 1-1/4” (32mm) to 1-1/2”
(28mm) of water. While not supplied with the food warmer,
it uses a 200 series cafeteria pan and any arrangement of
200 series pans in various sizes may be used. Individual
preference of operation will determine size of inserts to be
used. Pans may be purchased from your kitchen equipment
dealer.
Pizza Ovens – Model E22-22P & E22-22PP
Serial Plate Location
The serial plate is located on the main top.
Wall Clearances
Do not install closer to a will of combustible material than:
Sides 1/2” (13mm)
Back 1” (25mm)
Electrical Supply
For Supply Connection, use wire suitable for 60°C (140°F).
Electrical connection may be made through the knockout at
the rear or bottom of the unit to the terminal block located
behind the lower front panel.
Access to the terminal block is gained by removing two
lower front panel acorn nuts and hinging the lower front
panel down.
Pizza Oven Thermostat
Pizza ovens are equipped with snap action thermostats. Field
recalibration is seldom necessary and should not be resorted
to unless experience with cooking results definitely proves
that the control is not maintaining the temperature to which
the dial is set. To check oven temperature when calibrating,
use only a reliable mercury thermometer or preferably an
oven pyrometer. To check calibration, proceed as follows:
1. Place the thermocouple of the test instrument or reliable
mercury thermometer in the centre of the oven.
2. Turn the oven temperature control dial to 400°F (204°C).
In order to allow the oven temperature to stabilize, the
oven control must be allowed to cycle twice before
taking a test reading.
3. Check the temperature reading when the control just
cycles ‘OFF’ and again when the control just cycles ‘ON’ as
indicated by the cycling amber pilot.
4. If the AVERAGE of the two temperature readings do not
read between 15°F (8°C) of the dial setting, recalibrate as
follows:
5. Carefully remove the thermostat dial, not disturbing the
dial setting.
6. 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)
7. Replace the thermostat and repeat steps 1 through 4 to
verify that the correct adjustment has been made.
