location for two L-brackets per side (out of four possible locations
on each side) based on truss geometry.
6. Use additional screws from the accessory bag to plug any mounting

11. Electrical Connections ( Fig. 8 , Fig. 15 , and Fig. 16 ):
NOTE: Use proper strain relief when installing wiring to junction box.
a. For Furnace Units—Connect wiring from the EAC terminals to
a unit disconnect switch in the attic, and then connect the wiring
from the disconnect to the electrical box on the unit, using a
proper UL rated fitting at the electrical box knockout on the unit.
Follow standard wiring configuration: Black = high voltage;
White = neutral; Green = ground.
b. For Fan Coil Units—Connect wiring from the transformer using
the quick connect kit to the unit disconnect switch in the attic,
and then connect the wiring from the disconnect to the electrical
box on the unit, using a proper UL rated fitting at the electrical
box knockout on the unit. Follow standard wiring configuration:
Black = high voltage; White = neutral; Green = ground.
12. Reattach the electrical box cover. See Wiring on pg 6 for further
wiring details.
