!
NOTE: All wiring must comply with National Electrical
Code and local codes.
1. Insert approximately 15" (38cm) of supply wire into recess
box through knockout provided in upper left hand corner
(Figure 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 (Figure 1).
3. All units are factory prewired for operation with built-in
thermostat. If remote thermostat operation is required fol-
low appropriate wiring diagram located on inside of recess
box.
!
NOTE: It is recommended that for ceiling mount applica-
tions a remote thermostat be used in order to provide superior
temperature control.
!
NOTE: For applications where the unit is to operate at the
lower wattage, see wiring diagram located on inside of the
recess box for appropriate jumper to remove.
4. Secure heater assembly into recess box using the four M4
screws previously removed.
Front Panel Installation
1. Remove trim frame from front panel assembly. (Figure 3)
2. If tamper proof built-in or remote thermostat operation
is required, secure the louvered door to the front panel
using 2 M3 screws (not included) through the holes pro-
vided. The knob can then be removed and adjustment of
the thermostat can be made using a slotted screwdriver
