FACTORY OPTION THRU-BASE CONNECTIONS
This service connection kit consists of a
bulkhead connector and a
connector, connected to an "L" bracket covering the
embossed (raised) section of the unit basepan in the
condenser section (see Fig. 25 for shipping position).
The
/
-in. bulkhead connector enables the low-voltage
3
4
control wires to pass through the basepan. The
bulkhead connector allows the high-voltage power wires to
pass through the basepan. See Fig. 26.

1. Remove the "L" bracket assembly from the unit.
2. Remove connector plate assembly from the "L"
bracket and discard the "L" bracket, but retain the
washer head screws and the gasket (located
between the "L" bracket and the connector plate
assembly).
NOTE: Take care not to damage the gasket, as it is reused
in the following step.
3. Place the gasket over the embossed area in the
basepan, aligning the holes in the gasket to the holes
in the basepan. See Fig. 26.
4. Install the connector plate assembly to the basepan
using 8 of the washer head screws.
NOTE: If electrical connections are not going to occur at this
time, tape or otherwise cover the fittings so that moisture
does not get into the building or conduit in the interim.
Check tightness of connector lock nuts before connecting

Field-supplied
connectors 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).
Remove one of the two knockouts located on the bottom left
side of the unit control box. Use this hole for the control
conduit.
UNITS WITHOUT THRU-BASE CONNECTIONS
1. Install power wiring conduit through side panel open-
ings. Install conduit between disconnect and control
box.
2. Install power lines to terminal connections as shown
in Fig. 18.
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate. On 3-
phase units, voltages between phases must be balanced
within 2% and the current within 10%. Use the following for-
mula to determine the percent of voltage imbalance. Opera-
tion on improper line voltage or excessive phase imbalance
constitutes abuse and may cause damage to electrical
components. Such operation would invalidate any applica-
ble warranty.
