CAUTION
Do not use copper tubing or existing copper condensate
lines for drain line.

installation, prime trap per procedure outlined in the
Start-Up section.
Condensate line must slope downward away from the
trap to drain. If drain level is above condensate trap,
condensate pump must be used. Condensate drain

line should be routed within the conditioned space to
avoid freezing of condensate and blockage of drain
line. If this is not possible, a heat cable kit may be used
on the condensate trap and line. Heating cable kit is
available in various lengths; 6 ft. (1.8m) - kit no. 26K68;
24 ft. (7.3m) - kit no. 26K69; and 50 ft. (15.2m) - kit no.
