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 refrigerated 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).

2. Have a qualified electrician make the appropriate electrical
connections to the control panel. Refer to the wiring
diagram for details.
For CWBR models:
a. Connect the on-site power
supply through the power
input knockout
