Connecting the Components
Use the following procedure as a guideline for making
the connections between the components of the remote
refrigerated 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
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
®
) at a brazing
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 CSUR, CSBFR, CSSBR, and CSSBFR Models:
a. Connect the on-site power supply through the power
input cord grip to the POWER IN terminal block.
b. Connect power from the POWER OUT terminal block,
through the power output cord grip, to the power input
on the condensing unit.
c. Connect the temperature probe wire from the refrigerated
shelf to the probe wire from the digital temperature
controller.
