Thermostats
These fryers have 4 thermostats 2 primary and 2 secondary. There is one
primary and one secondary thermostat per tank. Only one thermostat per
tank is in use at a time. The thermostat selector switch on the front
display panel is used to select which thermostat is used to control the
fryer.
The secondary thermostat is designed to be used as a back up control if
the primary thermostat fails, or as an ‘IDLE’ thermostat when the oil needs
to remain hot but not cook.
If failure occurs in the Primary thermostat, set the thermostat selector
switch to the IDLE position to continue cooking with the secondary
thermostat. In the IDLE position, only the secondary thermostat is used –
by adjusting the setting of the secondary thermostat you can continue
operation. This will allow fryer to continue functioning until the primary
thermostat is repaired. After the repair has been made the switch can be
returned to the PRIMARY position.
Thermal Cut-Out
These fryers have a thermal cut-out control fitted for each tank. This
control is designed to function when the oil temperature reaches a
dangerous level. If the oil reaches that level the thermal cut-out will open,
cutting all power to the elements.
When the thermal cut-out has tripped, the red button on the control panel
will protrude out from the panel as an indication that this has occurred. If
the thermal cut-out has tripped, it indicates that there is an underlying
problem that has caused the oil to reach a dangerous temperature.
Note:
It is important to understand that old, dirty oil can contribute to
nuisance tripping of the thermal cut-out. Always ensure that your oil is
maintained and replaced when necessary.
What to do if the thermal cut-out trips for the first time:
There are a number of possible causes of this behaviour. One of the
possibilities is a thermostat failure. You may follow the procedure below as
a first step to rectifying the problem.
1. Switch the fryer OFF and allow it to cool to approximately 100°C.
2. Reset the thermal cut-out by pressing the red reset button. The
control is reset when the button remains depressed. An audible click
will also be heard.
3. Re-set the thermostat to the normal operating temperature and
observe the unit closely. If the unit trip the Thermal Cut-out switch
