The unit is designed to give years of safe, trouble-free operation when properly installed and maintained. Please
read the following guidelines to ensure reliable operation:
10. During normal operation, the limit controls are not supposed to cycle the heater ON and OFF. If frequent cycling of
the limit controls occurs, verify the minimum mounting clearances are maintained, proper operation of the room
thermostat and that there is no visible obstruction to the heater inlet or outlet. If this does not eliminate the limit
control cycling, the heater must be examined by qualified service personnel before further operation to determine
the cause.
11. Heater may be provided with a manual reset limit control (order code M). This limit control disables the electrical
function of the heater whenever excessive temperatures are present. If the manual reset limit control is suspected of
causing heater non-function then the heater must be disconnected from the heater electrical supply and examined by
a qualified service personnel. The personnel must determine the cause of the excessive temperatures, verify the
minimum mounting clearances, verify proper orientation of the heater, verify proper orientation of the room
thermostat, or if there are any obstructions or damage to the heater or heater inlet or heater outlet. The manual
reset limit control may be reset, after determining the cause, by removing the electrical enclosure cover and pressing
on the manual reset button. The location of the manual reset button within the electrical enclosure is shown in the
Maintenance Instructions.
12. Check out and report any unusual or questionable operating characteristics, such as noise, vibration, etc.
13. Set the temperature control thermostat to the desired room temperature setting and place unit in service.
