Fig. 13 - Condensate Drain Piping Details
All units must have an external trap for condensate
drainage. Install a trap at least 4 inches (102mm) deep and
protect against freeze-up. If drain line is installed
downstream from external trap, pitch line away from the
unit at 1 inch per 10 feet (25mm per 3m) of run. Do not
use a pipe size smaller than the unit connection (3/4 inch).

WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Unit cabinet must have an uninterrupted, unbroken
electrical ground to minimize the possibility of
personal injury if an electrical fault should occur. This
ground may consist of an electrical wire connected to
the unit ground lug in the control compartment, or
conduit approved for electrical ground when installed
in accordance with NEC; ANSI/NFPA 70, latest
edition (in Canada, Canadian Electrical Code CSA
[Canadian Standards Association] C22.1), and local
electrical codes.
NOTE:
Field- supplied wiring shall conform to the
limitations of minimum 63_F (33_C) rise.
