ERA & EBD SERIES ELECTRIC FRYERS - ELECTRICAL OPERATION
NOTE: If using solid shortening, allow hot
shortening to stand in filter tank for
approximately 6 minutes prior to filtering.
5. Turn filter power switch on.
A. R3 filter relay coil energized.
B. R3 N.O. contacts close.
1) Power supplied to pump motor and fill
solenoid.
6. Pump motor circulates shortening through filter
and solenoid to tank until power is removed.
7. When filtering process is completed and the
tank is full, turn off filtering switch.
A. Power is removed from pump motor and
solenoid closes.
NOTE: If using solid shortening, when all filtered
shortening is returned to the fry tank and filter power
switch is off, open the filter drawer approximately
one inch. Allow the remaining shortening in the line
to drain into the filter tank to prevent possible
clogging after the shortening cools and solidifies.
Close the filter drawer when complete.
8. To restart the cooking process, press the start
button.
Discarding Shortening
The discard valve handle is connected to a
mechanical valve and switch assembly to route the
flow of shortening (electrically and mechanically) out
discard hose.
Refer to Installation & Operation manual for specific
instructions on draining.
1. Conditions
A. Fryer connected to correct supply voltage
and is properly grounded.
B. Power switch to the fryer section off.
C. Shortening between 300°F and 350°F.
D. Filter drawer assembly installed properly.
E. Filter power switch off.
F. Discard valve handle (yellow) retracted.
1) Discard valve switch N.O. contacts
open. Mechanical discard valve
closed.
2. Turn power switch on, to the fryer section to be
drained.
3. Set cooking control between 300°F (minimum)
and 350°F (maximum).
NOTE: Shortening should not be drained outside of
this temperature range. At lower temperatures the
shortening is thicker which may increase draining
time and place a greater load on the pump. At higher
shortening temperatures, the pump seal life is
decreased.
A. Allow shortening to cycle at set
temperature for approximately 10 minutes.
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. Open the manual drain valve to the fryer
section in need of discarding and drain the
shortening into filter tank. (Heat circuit will be
disabled)
NOTE: If using solid shortening, allow hot
shortening to stand in filter tank for
approximately 6 minutes prior to discarding.
5. Connect discard hose. Place other end of
discard hose in appropriately-sized receptacle.
6. Pull out discard handle.
A. Discard switch N.O. contacts close.
B. R4 solenoid relay coil energized.
1)
7. Turn filter power switch on.
A. R3 filter relay coil energized.
B. R3 N.O. contacts close.
1)
8. Pump motor circulates shortening out discard
hose and into receptacle.
If discard receptacle is not large enough to
hold entire shortening amount, turn filter switch off to
stop pump motor . Empty receptacle and resume
discard operation by turning filter switch on.
9. When discard process is complete, turn off filter
switch.
A. Power is removed from pump motor.
10. Push in discard handle.
