Qmark B660W Infrared Heaters - Manual (Page 4)

THERMAL PROTECTION
This unit is Thermally Protected. If the cooling fan stalls or the unit is not field wired in accordance with the wiring
Diagrams (Fig. 3), the heat generated by the lamps will cause the protector to cut the unit off. After the unit has cooled off, the protector will
switch the unit back on, allowing the lamps to become energized. The unit will again heat up and cut off. This cycle will be repeated over and
over unless steps are taken to correct the problem. THIS CONDITION SHOULD NEVER BE ALLOWED TO CONTINUE. If necessary, the
unit should be serviced by an authorized representative.
In addition, the ventilator motor has an internal thermal protector in case the ventilator does not start when the ventilator switch is turned on.
This condition should be investigated. NEVER LEAVE SWITCH IN “ON” POSITION WHEN VENTILATOR DOES NOT START! Always
disconnect unit from power source before servicing it.
