INSTALLATION INSTRUCTIONS
Wiring Connections
Make all outdoor electrical supply (Line Voltage)
connections with raintight conduit and fittings. Most
codes require a disconnect switch outdoors within sight of
the unit. Consult local codes for special requirements.
Route electrical supply (Line Voltage) wiring through
knockout hole in bottom of Control Box. Connect wires to
Contactor and Ground Lug according to Wiring Diagram
on unit. Refer to Figure 9.
Route thermostat wiring through rubber grommet in
bottom of Control Box. Low voltage lead wires are
provided in the control box for connection to thermostat
wires (use wire nuts). Refer to Wiring Diagram on unit and
Figure 10 for low voltage wiring examples.
NOTE: Use No. 18 AWG (American Wire Gage)
color−coded, insulated (35 ° C minimum) wire. If
thermostat is located more than 100 feet (30.5 m) from
unit as measured along the control voltage wires, use No.
16 AWG color−coded wires to avoid excessive voltage
drop.
