All field wiring must be done in accordance with Na-
tional Electric Code recommendations, local codes and
applicable requirements of UL or in accordance with
Canadian Electrical Code, local codes and CSA Stan-
dards. Power wiring, disconnect means, and over--cur-
rent protection are to be supplied by installer. See unit
rating plate for maximum over--current protection,
minimum circuit ampacity, as well as operating volt-
age. The power supply must be sized and protected ac-
cording to specifications supplied. See figure 6 for field
connection of line voltage wiring and figure 7 for typi-
cal wiring diagram.

Unit must be grounded with separate ground conduc-
tor. The unit wiring diagram is located inside the unit
access panel. Low voltage control wiring are pigtail
leads located below the main control box and are color
coded to match the connection called out on the wiring
schematic.
If any of the original unit wiring is replaced, the same
size and type wire must be used. Electrical wiring must
be sized to carry minimum circuit ampacity marked on
the unit. Each unit must be wired with a separate
branch circuit and be properly fused.
