COMPLETE THE INSTALLATION
1. Install housing mask. A housing mask has been provided to
keep construction dust, drywall spray, paint, etc., from damag-
ing the heater. Bend the flap on the mask and push it into the
heater housing.
NOTE: Mask can be put into place before or after heater assembly
is reinstalled. Remove mask before operation.
2.
Reinstall heater assembly. Secure heater assembly to hous-
ing with four (4) screws. Check thermal overload button marked
"RESET". Heater will not operate unless this button is de-
pressed.
Refer to FIGURE 9
3.
Install grille. Place grille over heater and attach with four (4)
screws. Push knob onto thermostat stem.
4. Attach security cover to grille (optional). When heater is in-
stalled in a public area without a separate wall control, it is
recommended that:
a) Built-in thermostat be set to desired temperature level.
b) Thermostat knob be removed.
c) Security cover be attached to grille with two (2) screws, pro-
vided.
5. Check operation. Turn on power at service entrance. Turn ther-
mostat to its highest setting and make sure heating element
and blower come on. Then turn it to its lowest setting and make
sure element and blower shut off.
NOTE: The fan delay prevents the fan from coming on until the
element is hot. Likewise, it keeps the fan running until the element
cools down.
USE AND CARE
CAUTION – DISCONNECT POWER AT SERVICE ENTRANCE
AND LOCK OUT PANEL BEFORE CLEANING OR SERVICING
UNIT.
Thermal Overload Protector
Your heater is equipped with a manual-reset thermal overload pro-
tector. If heater fails to operate when thermostat is turned to its
highest setting:
1) Turn off power at service entrance.
2) Remove knob and grille.
3) Press button marked "RESET".
This type of device is particularly useful (compared to automatic
reset devices) because it encourages the user to find and correct
the cause of overheating unit when resetting the protector.
To avoid property damage when using this heater to prevent freeze-
ups:
Make sure heater functions properly before leaving unattended. A
tripped protector will prevent the heater from operating.
Cleaning
Clean the heater using the round brush tool on your vacuum cleaner.
Remove large accumulatoins of dust, lint, etc., that might impede
the flow of air through the heater. Such blockage will lower its effi-
ciency and create a possible overheating condition.
To clean grille, use a soft cloth which has been moistened with
household window cleaner.
CAUTION – METAL AND ELECTRICAL PARTS SHOULD NEVER
BE IMMERSED IN WATER.
