ELECTRICAL-LINE VOLTAGE

All field installed wiring, including electrical ground,
must comply with the National Electrical Code as well as
all applicable local codes.
Refer to the unit wiring diagrams for fuse sizes and a
schematic of the field connections which must be made by
the installing (or electrical) contractor.
Consult the unit wiring diagram located on the inside of the
compressor access panel to ensure proper electrical hookup.
All final electrical connections must be made with a
length of flexible conduit to minimize vibration and sound
transmission to the building.

To avoid possible injury or death due to

electrical shock, open the power supply

disconnect switch and secure it in an open

position during installation.

CAUTION: Use only copper conductors for field

installed electrical wiring. Unit terminals are not

designed to accept other types of conductors.

Table 5: Electrical Data

General Line Voltage Wiring

Be sure the available power is the same voltage and
phase as that shown on the unit serial plate. Line and
low voltage wiring must be done in accordance with
local codes or the National Electric Code, whichever is
applicable.

Unit Power Connection

Line voltage connection is made by connecting the
incoming line voltage wires to the “L” side of the
contactor as shown in Figure 16. Consult Table 5 for
correct wire and fuse size.

External Loop Power Connection

If the unit is to be used with an external loop pump, the
pump(s) will be connected to the loop pump terminals in
the unit electrical box as shown in Figure 17. The pumps
will automatically be cycled as required by the unit.

208 Volt Operation

All 208-230 Volt units are factory wired for 230 Volt.
The transformers may be switched to 208V operation as
illustrated on the wiring diagram.

HWG Pumping Wiring

Install HWG Pump power wires on HWG Pump power
block after insuring water is in HWG circuit.
