Refrigeration; Condensing Unit Access - Hussmann REACH-IN Installation & Operation Manual

» Risk of fire or explosion. R-290 (propane) refrigerant is flammable, and the refrigeration system should be
serviced or repaired only by trained service personnel. Do NOT puncture refrigerant tubing.

REFRIGERATION

Each self-contained case is equipped with its own condensing unit (2
units on 4- and 5-door cases, and on RLT3W). The refrigeration system
is factory charged and sealed. Each case has one electronic controller.
Self contained merchandisers use R-290 (propane), refrigerant. All
models have compressor(s). The systems employ capillary tubes
for refrigerant flow control. If the capillary tube becomes plugged or
damaged, replace the entire capillary tube. Refer to the case serial plate
for refrigerant charge information. The following illustration shows the
details of the refrigeration system.
