OPERATION—SAFETY TEST SYSTEM™
DANGER: BURN HAZARD
Contact with hot oil will cause severe burns. Allow the fryer to cool before cleaning.
Always wear protective clothing and heat resistant gloves when performing this test.
1. Fill the frypot to the MIN OIL line. Fresh oil is recommended to
minimize smoking.
2. Clip the TEST THERMOMETER to a
FRYER BASKET. Lower the fryer
basket into the oil. Be sure the dial
of the test thermometer can be
clearly viewed.
3. Turn the TEMPERATURE
CONTROL KNOB to the maximum
setting, then press the POWER
SWITCH to ON. Allow the oil to heat
until the test thermometer reads to
“START TEST” (350ºF).
4. Press and hold the red TEST
SWITCH. The temperature of the
oil will rise, and the test thermometer
will read “TEST ZONE”.
IMPORTANT: DO NOT hold the TEST switch for more than
2-1/2 minutes.
When the oil temperature reaches the setting of the hi-limit
thermostat, the hi-limit will trip, the red TROUBLE light will glow,
and the heating element will be de-energized.
If the hi-limit thermostat trips while the test
thermometer is in the TEST ZONE, the test is
complete. The function of the hi-limit
thermostat is normal. Reset the hi-limit
thermostat and resume normal operation.
If the test thermometer rises above the TEST
ZONE, the hi-limit is not operating properly.
Release the TEST switch, turn the power
switch OFF and contact an Authorized Wells
Service Agent for repairs.
5. Reset the hi-limit thermostat:
a. Turn the power switch OFF
b. Allow the oil to cool
c. Press the red button on the back of the element head until it
“clicks” and stays in.
6. Remove, clean and store the test thermometer.
Set the temperature control knob to the normal operating
temperature. Turn the power switch ON and resume normal
operation.
The Safety Test System™
allows a positive test of the
function of the temperature
limiting (hi-limit) thermostat.
The hi-limit thermostat is
factory set for 440ºF (227ºC).
It will trip if the oil temperature
exceeds this setting, and
interrupt power to the heating
element.
CAUTION
FIRE HAZARD
Do not hold the
TEST switch for more than 2-
1/2 minutes.
Should the oil temperature not
reach the hi-limit setting within
2-1/2 minutes, turn the power
switch OFF and contact an
Authorized Wells Service
Agent for repairs.
