NOMENCLATURE
Hydrocollator® Heating Units
WHITE LAMP,
when illuminated, indicates that main power is connected, the switch is on and
unit is operating.
RED LAMP (M-4 units),
when illuminated, warns of an overheat/low water condition. Action is
necessary to correct the condition.
IMPORTANT:
Some models (M-4 units) are fitted with a thermal cut-out thermostat which
acts as a “non self-resetting” thermal cut-out. In the unlikely event of a fault condition, this
device is designed to open the power circuit between 190° F ± 14° F (88° C ± 8° C). It is not
possible to alter its operating range. The operation of the unit may be restored by depressing
the red button after the water/element temperatures have been allowed to cool. If the fault
condition persists, please contact Chattanooga Group or an authorized agent.
