Placing the Fryer into Operation.
For units equipped with Thermostat
Controls:
Place the Melt Cycle switch (if equipped)
to the ON position. Set the thermostat
knob to the desired cooking temperature.
The U-shaped burner should “light-off”
and burn with a strong, blue flame.
CAUTION
Thermostat-controlled fryers will
stay in the Melt Cycle mode until
the Melt Cycle switch is placed in
the OFF position.
For units equipped with other than
Thermostat Controls:
Place the computer/controller ON/OFF
switch in the ON position and set the controller to—or program the computer for—
the desired cooking temperature, referred
to as the setpoint. The U-shaped burner
should “light off” and burn with a strong,
blue flame. The unit automatically enters
the Melt Cycle mode if the frypot temperature is below 180ºF (82ºC). (NOTE:
During the melt cycle, the burner will repeatedly fire for a few seconds, then go out
for a longer period.) When the frypot
temperature reaches 180ºF (82ºC), the unit
will automatically switch to the Heating
mode. The burner will remain lit until the
frypot temperature reaches the programmed cooking temperature (setpoint).
3.2 Boiling-Out the Frypot
To ensure that the frypot is free of any contamination resulting from its manufacture,
shipping, and handling during installation, the
frypot must be boiled out before first use.
Frymaster recommends boiling out the frypot
each time the oil or shortening is changed.
DANGER
Never leave the fryer unattended
during the boil-out process. If the boil-
out solution boils over, turn off power
to the fryer immediately and let the
solution cool for a few minutes before
resuming the process.
1. Before lighting the burner, close the fryer
drain valve(s) and fill the frypot to the
bottom OIL-LEVEL line with a mixture of
cold water and Frymaster™ FRYER ‘N’
GRIDDLE cleaner or detergent.
2. For units equipped with thermostat con-
trollers, set the thermostat to 280ºF
(140ºC).
For units equipped with analog or digital
°°°°
controllers, set the setpoint to 200
(93
°°°°
C).

CHAPTER 3: OPERATING INSTRUCTIONS
then add 2 gallons (7.75 liters) of cold
water and stir. Drain the solution into a
suitable container and clean the frypot
thoroughly.
WARNING
Do not drain boil-out solution into
the built-in filtration system. Doing
so may cause damage to the
filtration pump.
6. Rinse the frypot at least twice by filling the
frypot with clean water and draining. Dry
the frypot thoroughly with a clean, dry
towel.
DANGER
Remove all drops of water from the
frypot before filling with cooking
oil/shortening. Failure to do so may
cause spattering of hot liquid when
the oil/shortening is heated to
cooking temperature.
3.3 Shutting the Fryer Down
For short-term shut down during the work day,
place the fryer power switch in the OFF position and put the frypot covers in place (if the
fryer is so equipped).
When shutting the fryers down at closing time,
place the fryer power switch in the OFF position, place the gas valve in the OFF position,
