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.
