Wiring Diagrams
Unit specific wiring diagrams are laminated
and affixed inside the controls compartment
door.
Condensate Drain Pan
Unit requires drain traps to be connected to
the condensate drain pan of the unit. The 6-
25 and 30 ton units include one drain pan
connection and the 26 and 31-140 ton units
include two drain pan connections.
Condensate drain pipes or p-traps for each
connection are factory supplied and shipped
loose in the controls compartment for field
installation.
If codes require a condensate drain line, the
line should be the same pipe size or larger
than the drain connection, include a p-trap,
and pitch downward toward drain. An air
break should be used with long runs of
condensate lines.
Unit should not be operated without a
p-trap. Failure to install a p-trap may
result in overflow of condensate
water.
