WARNING
Consult a licensed electrical contractor for proper
electrical installation conforming to local electrical codes
and the National Electrical Code (N.E.C.).
16. Have a qualified electrician install a hardwired connection
between the unit and the on-site electrical system (refer to
the included wiring diagram for additional details).
• Units come complete with all electrical wiring. A 60"
(1524 mm) flexible conduit assembly with electrical
leads is located on the left side of the Hydro-Heater,
toward the rear. Check the specification label for the
proper electrical specifications.

Connecting the Components

Use the following procedure as a guideline for making
the connections between the components of the remote
refrigerated well system. These connections must be made by
trained and qualified installers and must comply with all local
plumbing and electrical codes. Refer to the SPECIFICATIONS
section and the wiring diagram included with the unit for details
regarding the plumbing and electrical connections.
1. Connect the liquid and suction refrigerant lines between
the condensing unit, the TXV valve, and the hot/cold well
evaporator coil. Refer to the appropriate illustration below
and the SPECIFICATIONS section for connection details.
NOTE: The maximum refrigerant line length between the
condensing unit and the evaporator coil is 50 feet (15 m).
NOTE: For refrigerant line connections, use a self-fluxing
brazing compound (example = Sil-Fos 5
temperature range of 1300–1500°F (704–816°C).
