Over Temperature Protection

In the unlikely event that the programmed hi-limit and the
user adjustable hi-limit thermostats fail, there is a third
over temperature thermostat.  The thermostat is located
underneath the shaker's back panel.  If the shaker fails to
heat with the "HEAT ON" lamp lit and the user settable hi-
limit thermostat set to the fully clockwise position, it will be
necessary to reset the secondary over temperature ther-
mostat.  To do so, proceed as follows:

1.

Disconnect power cord from outlet.

2.

Remove rear panel.

3.

Locate the thermostat on top of plenum.  The
thermostat has a small button that needs to be
pressed in to reset the thermostat.

4.

Once the thermostat is reset, reinstall the rear
panel, plug the power cord back into the outlet
and verify the unit is heating again.

5.

If the shaker still fails to heat, contact Customer
Service for further assistance.
