REFRIGERATION

Each self-contained case is equipped with its own
condensing unit(s), one for every 2 or 3-door. The
refrigeration system is factory charged and sealed.
Each case has one electronic controller. Thus, a
2-door case has one condensing unit, a 4-door case has
two condensing units.
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.

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.
