GR SERIES GAS FRYERS - ELECTRICAL OPERATION
6. Cooking control cycles heat output on frying oil
temperature until power switch is turned off; Ignition
input status is removed; Drain valve interlock input
status is removed; temperature probe input is outside
acceptable limits or a high limit condition occurs.
NOTE:
Steps 6A and 6B discuss open high limits. For
additional information on cooking control error
messages, refer to “TROUBLESHOOTING”.
A. If frying oil reaches 415°F or higher, the
cooking control de-activates the heat output and
basket lift outputs, cooking timers are cancelled (if
active), keypad is disabled, display indicates “HI”,
and the electronic alarm will sound continuously.
Turn power switch off to silence the alarm. Normal
operation resumes when temperature drops below
415°F.
B. If frying oil reaches 450°F, the high limit
thermostat opens, power is removed from the pilot
valve and closes to stop pilot gas flow.
1) Ignition trial cycle will start but pilot will be
unable to light. After several seconds of ignition
trial time, the cooking control displays a
message indicating “pilot out” or “ignition
failure” as the ignition module continues to
generate a spark at the ignitor. After 90
seconds, the ignition module locks out power to
the gas valve. With the ignition status input
removed from cooking control, a message is
displayed by the control indicating “ignition
lockout”; keypad is disabled and the electronic
alarm will sound continuously. Turn power
switch off to silence the alarm and reset the
system. Normal operation will resume when the
temperature drops below 415°F.
Kleenscreen Filtering System
Refer to wiring diagram 7410.
The filter valve handle and the discard valve handle are
connected to a mechanical valve and switch assembly
to route the flow of oil in the filtering system and supply
power to the pump motor.
NOTE:
The computer control contains a program feature
that allows the operator to program a specific number of
timed cooking cycles to complete then alert the operator
to filter the frying oil/shortening. When the actual
cooking count reaches the filter count setting, “FILTER”
will flash in the right display when fryer is idle. Normal
fryer operation continues without a cooking lockout. This
feature can also be disabled. Refer to Installation &
Operation manual for specific instructions on filtering.
1. Conditions
A. Fryer connected to correct supply voltage and is
properly grounded .
NOTE:
Separate connections are required for the
fryer controls and the filtering system controls.
B. Power switch to fryer section turned off.
C. Frying oil between 300°F and 350°F.
D. Filter drawer assembly installed properly.
E. Filter power switch turned off.
F. Filter valve handle (red) retracted.
1) Filter valve switch N.O. contacts open.
G. Discard valve handle (white) retracted.
1) Discard valve switch N.O. contacts open.
NOTE:
On computer control fryer’s, the control
should be setup properly and ready to use.
2. Turn the power switch on, to the fryer section to be
filtered.
3. Set cooking control between 300°F (minimum) and
350°F (maximum).
NOTE:
Oil should not be filtered outside of this
temperature range. At lower temperatures the oil is
thicker which may increase filtering time and place a
greater load on the pump. At higher oil temperatures, oil
seal life is decreased.
A. Allow oil to cycle at set temperature for
approximately 10 minutes.
NOTE:
If using solid shortening, once it has
melted, stir the oil to eliminate any sold shortening
in cold zone of the fry tank.
4. Solid State Control:
A. Turn the power switch off, to the fryer section to
be filtered.
B. Open the drain valve to the fryer section in need of
filtering and drain the frying oil/shortening into filter
tank.
NOTE:
If using solid shortening, allow hot
shortening to stand in filter tank for approximately
6 minutes prior to filtering.
NOTE:
Drain valve interlock contacts open and
the position of the drain valve is indicated to the
cooking control.
C. Turn filter power switch on.
1) Switch pilot light comes on.
D. Extend Filter valve handle of the same fryer
section.
1) Filter valve switch N.O. contacts close.
a. Power supplied to pump motor.
E. Pump motor circulates oil through filter until power
is removed.
