ELECTRIC RESISTANCE HEATER ASSEMBLY
ELECTRICAL SHOCK HAZARDS. ALL
POWER MUST BE DISCONNECTED
PRIOR TO INSTALLATION AND SERV-
ING THIS EQUIPMENT. MORE THAN
ONE SOURCE OF POWER MAY BE
PRESENT. DISCONNECT ALL POWER
SOURCES TO AVOID ELECTROCUTION OR SHOCK
INJURIES.
Electric resistance heaters typically require no normal
periodic maintenance when unit air lters are changed
properly. Other conditions and equipment may affect the
operation and service life in the system. The two most
important operating conditions for an electric heater are
proper airow and proper supply voltage. High supply
voltage and/or poorly distributed or insufcient airow
over the element will result in element overheating.
This condition may result in the heater cycling on the
high limit thermal cutout. The open wire type heaters
provided have an automatic reset switch with a back-up
high limit thermal switch. Automatic reset switches are
as the name implies; they reset automatically after the
heater has cooled down. High limit thermal switches
must be replaced once the circuit has been broken.
The high limit thermal cutout device is a safety device
only and is not intended for continuous operation. With
proper unit application and during normal operation,
the high limit thermal cutout will not operate. This
device only operates when some problem exists and
ANY condition that causes high limit cutout MUST be
corrected immediately. High supply voltage also causes
excessive amperage draw and may result in tripping
of the circuit breaker or blowing of the fuses on the
incoming power supply.
ELECTRICAL WIRING & CONTROLS
The electrical operation of each unit is determined by
the components and wiring of the unit and may vary
from unit to unit. Consult the wiring diagram for the
actual type and number of controls provided on each
unit. The integrity of all electrical connections should be
veried at least twice during the rst year of operation.
Afterwards, all controls should be inspected regularly
for proper operation. Some components may experience
erratic operation or failure due to age. Wall thermostats
may also become clogged with dust and lint and should
be periodically inspected and cleaned to provide reliable
operation.
When replacing any components such as fuses,
contactors, or relays, use only the exact type, size, and
voltage component as furnished from the factory. Any
deviation without factory authorization could result
in personnel injury or damage to the unit and will
void all factory warranties. All repair work should be
done in such a manner as to maintain the equipment in
compliance with governing codes and ordinances or
testing agency listings.
