If the installation requires draining the condensate water
away from the unit, install a field-supplied 2-in. trap using
3
⁄
-in. OD tubing or piping to ensure proper drainage. See
4
Fig. 8A and 8B. Make sure that the outlet of the trap is at
least one in. lower than the unit drain pan condensate con-
nection to prevent the pan from overflowing. Connect a drain
tube using a minimum of
copper pipe (all field-supplied). Do not undersize the tube. Pitch
the drain tube downward at a slope of at least 1 inch in every
10 ft of horizontal run. Be sure to check the drain tube for
leaks. Prime trap at the beginning of cooling season start-up.
Allowable glues for condensate trap connection are: Stand-
ard ABS, CPVC, or PVC cement.
B. Field-Duct Connections
NOTE: The design and installation of the duct system must
be in accordance with the standards of NFPA for the instal-
lation of nonresidence-type air conditioning and ventilating
systems, NFPA 90A or residence-type, NFPA 90B, and/or
local codes and ordinances.
Units have duct flanges on the supply- and return-air open-
ings on the side of the unit. See Fig. 2-4 for connection sizes
and locations.
