tion can be used with vertical or horizontal applications.
To use the alternate bottom drain connection, remove the red
drain plug from the bottom connection (use a
et drive extension) and install it in the side drain connection.
The piping for the condensate drain and external trap can be
completed after the unit is in place. See Fig. 16.

NOTE: Trap should be deep enough to offset maximum unit static
difference. A 4-in. (102 mm) trap is recommended.
Fig. 16 — Condensate Drain Piping Details
All units must have an external trap for condensate drainage.
Install a trap at least 4-in. (102 mm) deep and protect against
freeze-up. If drain line is installed downstream from the exter-
nal trap, pitch the line away from the unit at 1-in. per 10 ft
(25 mm in 3 m) of run. Do not use a pipe size smaller than the
unit connection ( 3 / -in.).

ELECTRIC 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 elec-
trical wire connected to unit ground lug in control compart-
ment, 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 with the limitations
of minimum 63°F (33°C) rise.
