CONDENSATE DRAIN
Note the difference between the primary and secondary
openings. Attach drain line to pan with included 90 degree
ELL. Hand tight is adequate—do not over tighten & do not
reduce drain line size!
Included drain hose will fit over the PVC fitting and should be
secured with included hose clamp; a field supplied PVC fitting
can be used if required by code. Route drain line(s) so they
will not be exposed to freezing temperatures and do not
interfere with accessibility to the coil, air handling system or
filter. Stretch hose to form a 2" water trap, then wrap using
field supplied tape (Figure 3). Locate trap under home but as
close to the coil as possible.
A WATER TRAP is required on electric furnace installations,
and is recommended for all installations. Failure to use a
water trap can cause improper drainage, leading to a
shock hazard or property damage. Test drain lines with
water before running the system.

IMPORTANT
The Clean Air Act of 1990 bans the intentional venting
of refrigerant (CFC’s and HFC’s). Approved methods
of reclaiming must be followed. Fines and/or incarcera-
tion may be levied for non-compliance.
