Step 11 — Install External Condensate Trap and
Line
The unit has one
3
/
4
-in. condensate drain connection on
the end of the condensate pan (see Fig. 18) See Fig. 1 (or
Fig. 2), item “E”, in the view labeled “BACK
(HORIZONTAL DISCHARGE)” for the location of the
condensate drain connection.

Fig. 18 -- Condensate Drain Pan Connection
The piping for the condensate drain and external trap can
be completed after the unit is in place. Hand tighten
fittings to the drain pan fitting. Provide adequate support
for the drain line. Failure to do so can result in damage to
the drain pan. See Fig. 19.
NOTE: Trap should be deep enough to offset maximum unit static
difference. A 4” (102) trap is recommended
.

Fig. 19 -- 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 external 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
(

-in.).
Step 12 — Make Electrical Connections
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Do not use gas piping as an electrical ground.
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 electrical wire connected to
unit ground lug in control compartment, or conduit
approved for electrical ground when installed in
accordance with NEC (National Electrical Code);
ANSI/NFPA 70, latest edition (in Canada, Canadian
Electrical
Code
CSA
[Canadian
Standards
Association] C22.1), and local electrical codes.

WARNING
NOTE
: Check all factory and field electrical connections
for tightness. Field--supplied wiring shall conform with
the limitations of 63
_
F (33
_
C) rise.
Field Power Supply —
If equipped with optional Powered Convenience Outlet:
The power source leads to the convenience outlet’s
transformer primary are not factory connected. Installer
must connect these leads according to required operation
of the convenience outlet. If an always--energized
convenience outlet operation is desired, connect the
source leads to the line side of the unit--mounted
disconnect. (Check with local codes to ensure this method
is acceptable in your area.) On a unit without a
unit--mounted disconnect, connect the source leads to the
terminal block with unit field power leads.
Field power wires are connected to the unit at line--side
pressure lugs on the terminal block (see wiring diagram
label for control box component arrangement) or at
factory--installed option non--fused disconnect switch. Use
copper conductors only.
NOTE
: Make field power connections directly to line
connection pressure lugs only.
All units except 208/230-v units are factory wired for the
voltage shown on the nameplate.
If the 208/230-v unit is
to be connected to a 208-v power supply, the control
transformer must be rewired by moving the black wire
with the
1
/
4
-in. female spade connector from the 230--v
connection and moving it to the 208-v
1
/
4
-in. male
terminal on the primary side of the transformer.
