Level unit by either hand-cranking or using
adjustable wrench (see below). Return grilles.
2. Dipslay Case Start-Up
Lift up controls cover on control side of unit
(see illustrations below).
Turn on main power switch.
Main power switch will start evaporator coil
fans, and the compressor motor.
3. Temperature Control Access
Lift up controls cover on control side of unit.
See the temperature controller section of this
manual for instructions and details on proper
temperature controller settings.
4. 41 °F / 38 °F Temperature Control Switch
“O” (Open Position Switch Setting): Controller
maintains the preset value for “Red Meat”.
“I” (Closed Position Switch Setting): Controller
modifies the set point, adding the value of the
parameter (r4). For example, when ‘r4’ = 3 °F (as a
preset value), switching to “I” (closed position) will
INCREASE the setpoint by 3.0 °F for “Produce”.
To raise or lower temperature setpoints BEYOND the
preset values, see CAREL CONTROLLER:
Changing “Red Meat” and “Produce” Set points
Using The Thermostat Controller section in manual
.

Acrylic Airflow Piece Setup
Due to unique airflow needs, multiple acrylic pieces are to be
carefully placed at specific places on the case.
Illustrations below reflects this layout.
Caution! Improper acrylic airflow piece setup can
result in fogging or improper temperature variance.
Make certain that the inner and outer curved airflow
pieces BOTH are inserted in the appropriate bracket
(as illustrated).
Make certain that the flat air shield is inserted in the flat air
shield bracket (as illustrated).
See next page for exploded pictorial of acrylic airflow
pieces.
