Units Without Factory--Installed
Non--Fused Disconnect —
When installing units, provide a disconnect switch per
NEC (National Electrical Code) of adequate size.
Disconnect sizing data is provided on the unit informative
plate. Locate on unit cabinet or within sight of the unit per
national or local codes. Do not cover unit informative
plate if mounting the disconnect on the unit cabinet.
All Units —
All field wiring must comply with NEC and all local
codes. Size wire based on MCA (Minimum Circuit Amps)
on the unit informative plate. See Fig. 14 and the unit
label diagram for power wiring connections to the unit
power terminal blocks and equipment ground. Maximum
wire size is #2 ga AWG per pole.
Provide a ground--fault and short--circuit over--current
protection device (fuse or breaker) per NEC Article 440
(or local codes). Refer to unit informative data plate for
MOCP (Maximum Over--current Protection) device size.
All field wiring must comply with the NEC and local
requirements.
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 200-v
1
/
4
-in. male
terminal on the primary side of the transformer.
Refer to
unit label diagram for additional information. Field power
wires will be connected line--side pressure lugs on the
power terminal block or at factory--installed option
non--fused disconnect.
NOTE
: Check all factory and field electrical connections
for tightness.
Convenience Outlets —
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Units with convenience outlet circuits may use
multiple disconnects. Check convenience outlet for
power status before opening unit for service. Locate
its disconnect switch, if appropriate, and open it.

Fig. 18 -- Convenience Outlet Location
Non--powered Convenience Outlet:
These outlets require
the field installation of a general--purpose 125--volt 15--A
circuit powered from a source elsewhere in the building.
Observe national and local codes when selecting wire
size, fuse or breaker requirements and disconnect switch
size and location. Route 125--v power supply conductors
into the bottom of the utility box containing the duplex
receptacle.
Installing
Weatherproof
Cover:
A
weatherproof
while-in-use cover for the factory-installed convenience
outlets is now required by UL standards. This cover cannot
be factory-mounted due its depth; it must be installed at unit
installation. For shipment, the convenience outlet is covered
with a blank cover plate.
The weatherproof cover kit is shipped in the unit’s control
box. The kit includes the hinged cover, a backing plate and
gasket.
DISCONNECT
ALL
POWER
TO
UNIT
AND
CONVENIENCE OUTLET. LOCK--OUT AND TAG--OUT
ALL POWER.
Remove the blank cover plate at the convenience outlet;
discard the blank cover.
Loosen the two screws at the GFCI duplex outlet, until
approximately
1
/
2
-in (13 mm) under screw heads are
exposed. Press the gasket over the screw heads. Slip the
backing plate over the screw heads at the keyhole slots
and align with the gasket; tighten the two screws until
snug (do not over-tighten).
Mount the weatherproof cover to the backing plate as
shown in Fig. 19. Remove two slot fillers in the bottom of
the cover to permit service tool cords to exit the cover.
Check for full closing and latching.
