Specifications are subject to change without notice.
Prime all traps, test for leaks, and insulate in areas where
sweating of the traps and drain lines could potentially cause
water damage. Consult local codes for additional
requirements or precautions.
If a gravity drain cannot be used, install a condensate pump.
Install the pump as close to the indoor section as possible.

CAUTION
PRODUCT or PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in product or
property damage.
Use only full size P- traps in the condensate line (refer to
Figure 16). Shallow, running traps are inadequate and
DO NOT allow proper condensate drainage (refer to
Figure 17).
