Supply Wiring and Heater Installation
1.
Insert approximately 15” (38cm) of supply wire into recess box through knockout provided in upper left hand corner (Fig. 2b).
Wire should be rated for a minimum of 75°C (167°F)
2.
Connect power supply to terminals provided marked L1 and L2. Ground wire should be secured to green ground screw
provided on side of heater assembly (Fig. 1).
3.
All units are factory prewired for operation with built-in thermostat. If remote thermostat operation is required follow
appropriate wiring diagram located on inside of recess box.
TIP - It is recommended that for ceiling mount applications a remote thermostat be used in order to provide superior temperature
control.
NOTE -All wiring must comply with National Electrical Code and local codes.
4.
Secure heater assembly to recess box using four 8 - 18 x 5/16” screws provided. Ensure that the four speed clips are
attached to heater assembly top and bottom.
Front Panel Installation
1.
Remove trim frame from front panel assembly. (Fig. 3)
2.
If tamperproof built-in or remote thermostat operation is required, secure the louvered door to the front panel using 2 No. 6
screws (not included) through the holes provided. The knob can then be removed and adjustment of the thermostat can be
made using a slotted screwdriver through the front panel.
3.
Check to see that the fan blade is free to turn and that no residue remains in the unit. Front panel can then be secured to
assembly using four 8 - 18 1/4” screws provided.
Operation and Maintenance
1.
Set thermostat to desired temperature and both fan and heat should come on. Note that when desired temperature is
reached the fan operation will continue for a short period after the elements have de-energized in order to remove residual
heat from the unit.
2.
The fan motor is permanently lubricated and sealed at the factory and is maintenance free.
3.
It is suggested that at the beginning of each season the front panel is removed and the wire connection condition is checked
and the unit is cleaned of dust and dirt with a vacuum cleaner.
NOTE - Always open the circuit breaker to disconnect power to the unit prior to performing any maintenance or service operation.
WARNING - Should the Over Temp light come on, disconnect power to the heater or turn down the thermostat fully
counterclockwise and call a licenced electrician. DO NOT USE HEATER UNTIL PROBLEM IS
DETERMINED AND FIXED.
