Refrigeration Module
The optional Refrigeration Module quickly and quietly cools
the internal chamber to the user’s specifications. The
module is mounted on top of the “dirty” side of the pass-
through and requires that a support frame be installed
below the pass-through (see
Figure 4
).
Be sure the evaporator drain tube exits from the bottom of
the pass-through (see
Figure 21
). Connect the drain tube
to an appropriate drainage device.
Turn on the unit using the green master power switch on
the “dirty” side of the pass-through. The temperature
controller is preconfigured for basic operation prior to
shipment.
To prevent overheating of the compressor and evaporator coils, the refrigeration module’s air intake and
exhaust vents must be clear of obstruction after installation.
