8.0 OVERHEAT PROTECTION
8.1 The heater is equipped one (1) high limit thermocouple
per heating bank to sense the heating element sheath
temperature. Each high limit thermocouple must be wired to a
separate Certified, manual-reset high limit controller in the
control panel. The set point of the controller(s) must not exceed
the values given in Table 2.
8.2 In the event of fan failure, excessive dust buildup, or
restricted airflow, the heater temperature may rise, causing the limit
controls to open and break the power supply to the heater.
CYCLING OF THE HEATER ON THE HIGH
LIMITS SHOULD NOT BE PERMITTED. Should
this occur, the system should be inspected to
determine the cause of the cycling, and the
condition must be corrected before regular
operation is resumed.
9.0 MAINTENANCE
DISCONNECT ALL POWER TO THE
EQUIPMENT PRIOR TO SERVICING.
9.1 Periodically inspect the heater installation to ensure that all
connections, fitting, plugs, screws, covers, etc. are tight and free of
corrosion.
9.2 Check the surface of the duct section and terminal boxes
for dust and debris, especially after seasonal shutdowns. Clean
with a blast of air or vacuum.
