The unit will use less
energy, run less, and
maintain even product
temperature with a clean
condenser.
To clean the Condenser,
begin by raising the front
lower panel up and off
the panel brackets. Pull
the bottom edge out and
allow the panel to clear
the upper retainers.
Turn the power switch
to “OFF” (see Page 1).
Use a vacuum hose or
soft brush (non-metallic)
to remove dust and
debris from the surface
of the condenser. Be
careful to not damage the
condenser.
Once condenser is clean,
turn the power switch
“ON” and re-install the
lower front panel.

Cleaning the interior of a
self-contained display is
similar to cleaning
remote displays with one
major exception:
NEVER USE A HOSE!
The evaporator pan of
the self-contained display
is sized to eliminate
condensate from the
refrigeration process,
similar to a residential
refrigerator.
The evaporator pan must
be cleaned regularly.
