REFRIGERATION
Each Insight self-contained case is equipped
with its own condensing unit(s), one for every
4-foot module. The refrigeration system is
sealed and factory charged. Thus, a 4-ft case
has one condensing unit, an 8-ft case has two
condensing units and a 12-ft case has three
condensing units. Each case has one electronic
controller.
Insight self contained merchandisers use R-290
(propane), refrigerant. All models have her-
metic compressor(s). The systems employ cap-
illary 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 informa-
tion.
Attention trained service personnel:
Mandatory safety service procedures
must be followed when servicing 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.
CONDENSING UNIT ACCESS
Condensing units may be located on top of the
case or behind the interior back panels depending
on the case model. Remove the metal covers(s)
to gain access to the condensing unit(s). All the
cases and condensing units' electrical connections
are done at the factory. The illustration shows
the condensing unit and the metal enclosure.
See location details on next Page.
Opening condensing unit electrical
box exposes personnel to electrical
hazard and should only be preformed
by a qualified service technician.
