OPERATION INSTRUCTIONS
1. This heater must be properly installed before it is used.
2. If the heater is equipped with a built-in thermostat, adjust the
shaft to the mid-range and let the heater run for a few hours.
If the room temperature is too hot, rotate the shaft counter-
clockwise; if too cool, rotate the shaft clockwise until a com-
fortable temperature is obtained. Let room temperature sta-
bilize after each setting change. The heater will automatical-
ly cycle around this set point on the thermostat.
Note: If a thermostat or disconnect switch is provided in the
heater, these components are accessible through the grille
openings at the left or right end of the heater.
MAINTENANCE INSTRUCTIONS
For efficient and safe operation and to extend the life of the
heaters, they should be cleaned and inspected for damage at
least annually (preferably at the beginning fo the heater season)
or more often in dirty environments. Other than cleaning, your
heaters require no other preventative maintenance.
1. The user can perform periodic cleaning of the outer cabinet.
All other servicing is to be done by qualified service person-
nel.
2. Heater cabinet may be cleaned using a damp cloth to
remove dust that may have accumulated on surfaces. Do not
use harsh cleaners or waxes on surfaces since these could
damage the finish or discolor in use.
3. A vacuum cleaner and/or compressed air may be used to
remove dust and lint that may have accumulated inside
heater around element fins. If heater must be disassembled
for cleaning, use care when cleaning element fins to avoid
damaging fins.
4. After cleaning and servicing, always reassemble replacing
any hardware removed, restore power and check to make
sure the heaters are operating properly.
Important Note: There are built-in safety devices provided within
the heaters including one or more over-temperature limit con-
trols (Thermal Protector) - see Wiring Diagram on heater for
specific controls provided. These safety controls are provided to
cycle the heater off to maintain safe temperatures in the event of
a blockage or other abnormal condition. DO NOT remove or
bypass these important safety controls as they are provided to
limit the temperatures and prevent a possible fire in the event
the heater is subjected to an overheating condition. If it is deter-
mined that the heater is cycling off on the safety controls during
normal use, discontinue using the heater until it can be
inspected and repaired by a qualified service personnel.
1. Serious injury or death could result from electric shock.
Make sure electrical power supply circuit(s) coming to
heater is/are disconnected at main disconnect or service
panel before servicing this heater. Allow heater to cool
before cleaning to prevent a possible burn.
Note: More than one power source may enter heater. Be
sure all power is disconnected to heater before cleaning or
servicing.
2. Use care when cleaning element fins to avoiding damaging
fins. Note also that fins are sharp and may cause cuts so
avoid contact.
