5. Remove the thermometer or pyrometer.
If calibration cannot be obtained for any rea-
son, call a Factory Authorized Service Center
for assistance.
Check Thermostat Controller Thermostat
Calibration
(This check applies only to units equipped
with Thermostat Controllers)
1. Set the temperature control knob to 325° F
(162° C) and insert a good grade ther-
mometer or pyrometer into the frypot so
that it touches the temperature probe
guard.
2. When the burner cycles off, set the tem-
perature control knob to 340° F (170° C).
As the reading on the thermometer or py-
rometer nears the control knob setting, but
before the burner cycles off, reset the knob
to 325° F (162° C). Just as the reading on
the thermometer or pyrometer drops below
325° F (162° C), the burner should cycle
on. If it does not, calibration is required.
Call your Factory Authorized Service
Center (FASC) to arrange this service.
