Non-Powered Convenience Outlet
This type requires the field installation of a general-purpose
125v 15A 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 125v power supply conductors into the
bottom of the utility box containing the duplex receptacle.
Unit-Powered Convenience Outlet
A unit-mounted transformer is factory-installed to step
down the main power supply voltage to the unit to 115v at the
duplex receptacle. This option also includes a manual switch
with fuse, located in a utility box and mounted on a bracket be-
hind the convenience outlet; access is through the unit's control
box access panel. See Fig. 29.
The primary leads to the convenience outlet transformer are
not factory-connected. Selection of primary power source is a
customer option. If local codes permit, the transformer primary
leads can be connected at the line-side terminals on the unit-
mounted non-fused disconnect switch; this will provide service
power to the unit when the unit disconnect switch is open. Oth-
er connection methods will result in the convenience outlet cir-
cuit being de-energized when the unit disconnect switch is
open. See Fig. 33.

Fuse On Power Type
The factory fuse is a Bussman "Fusetron"
non-renewable screw-in (Edison base) type plug fuse.
Test the GFCI receptacle by pressing the TEST button on
the face of the receptacle to trip and open the receptacle. Check
for proper grounding wires and power line phasing if the GFCI
receptacle does not trip as required. Press the RESET button to
clear the tripped condition.

Using Unit-Mounted Convenience Outlets
Units with unit-mounted convenience outlet circuits will of-
ten require that two disconnects be opened to de-energize all
power to the unit. Treat all units as electrically energized until
the convenience outlet power is also checked and
de-energization is confirmed. Observe National Electrical
Code Article 210, Branch Circuits, for use of convenience
outlets.
FACTORY-OPTION THRU-BASE CONNECTIONS
(ELECTRICAL CONNECTIONS)
This service connection kit consists of a
adapter fitting (brass), a
and a

-in. electrical bulkhead connector, all factory-installed

in the embossed (raised) section of the unit basepan in the con-
denser section. The
voltage control wires to pass through the basepan. The
electrical bulkhead connector allows the high-voltage power
wires to pass through the basepan. See Fig. 17 on page 14.
Check tightness of connector lock nuts before connecting
electrical conduits.
Field-supplied and field-installed liquid tight conduit con-
nectors and conduit may be attached to the connectors on the
basepan. Pull correctly rated high voltage and low voltage
through appropriate conduits. Connect the power conduit to the
internal disconnect (if unit is so equipped) or to the external
disconnect (through unit side panel). A hole must be field cut
in the main control box bottom on the left side so the 24-v con-
trol connections can be made. Connect the control power con-
duit to the unit control box at this hole.
UNITS WITHOUT THRU-BASE CONNECTIONS
(ELECTRICAL CONNECTIONS)
1.
Install power wiring conduit through side panel openings.
Install conduit between disconnect and control box.
2.
Install power lines to terminal connections as shown in
Fig. 25 on page 16.
FIELD CONTROL WIRING
The 582K unit requires an external temperature control
device. This device can be a thermostat (field-supplied) or a
thermostat emulation device provided as part of a third-party
Building Management System or the RTU Open Multi-
Protocol Controller (RTU Open is available as a factory-
installed option only).
THERMOSTAT
Install a Bryant-approved accessory thermostat according to
installation instructions included with the accessory. For com-
plete economizer function, select a two-stage cooling thermo-
stat. Locate the thermostat accessory on a solid wall in the con-
ditioned space to sense average temperature in accordance with
the thermostat installation instructions. Typical low-voltage
connections are shown in Fig. 34.
If the thermostat contains a logic circuit requiring 24v pow-
er, use a thermostat cable or equivalent single leads of different
colors with minimum of seven leads. If the thermostat does not
1
T-15,
require a 24v source (no "C" connection required), use a ther-
mostat cable or equivalent with minimum of six leads. Check
the thermostat installation instructions for additional features
which might require additional conductors in the cable.
For wire runs up to 50 ft (15 m), use no. 18 AWG (Ameri-
can Wire Gage) insulated wire [95°F (35°C) minimum]. For 50
to 75 ft (15 to 23 m), use no. 16 AWG insulated wire [95°F
(35°C) minimum]. For over 75 ft (23 m), use no. 14 AWG in-
sulated wire [95°F (35°C) minimum]. Wire sizes larger than
no. 18 AWG cannot be directly connected to the thermostat and
will require a junction box and splice at the thermostat.
