V. a - ADJUSTING THE TEMPERATURE:
The refrigeration system has been properly charged
and tested at the factory. Plug the unit into the power
outlet to determine if the compressor(s) is running. If
not, check the “ON/OFF” switches behind the louver
assembly. On a refrigerator/freezer models (UR48DT)
there are separate switches for each compartment (lo-
cated on the right side) and both must be in the ON
position.
If, after determining that your Spacesaver unit is func-
tioning, and has had adequate time to pull-down tem-
perature, the temperature is above/below standard
ranges (34 to 38° F for refrigerators, 0 to -5° F for freez-
ers), adjust the temperature controls. This is a black
knob located behind the louver assembly along the
centerline. It can be adjusted up or down one number
at a time to raise or lower temperature.
V. b - AUTOMATIC DEFROST:
The refrigerator section operates on a “cycle defrost”
basis, which means, at the end of each refrigeration
cycle, the coil is allowed to reach 42° F and defrost
itself. This method allows for maximum efficiency of
the refrigeration system.
The freezer section is normally frost free and never
requires a manual defrost. When the defrost system is
operating, the compressor and fans do not run.
WARNING: DISCONNECT ELECTRICAL POWER
SUPPLY BEFORE CLEANING ANY PARTS OF THE

V. OPERATION VI. CARE & MAINTENANCE
VI. a - CLEANING THE CONDENSER:
The most important thing you can do to insure a long,
reliable service life for your Traulsen is to regularly
clean the condenser coil.
The condensing unit requires regularly scheduled
cleaning to keep the finned condenser clean of lint
and dust accumulation. The frequency of cleaning
will depend on jobsite conditions, however at least
once a month is strongly recommended. Keeping the
condenser clean allows the cabinet to operate more
efficiently and use less energy.
To clean the condenser, first disconnect electrical
power to the cabinet and lift up the front louver as-
sembly. To lift this, remove the two screws located on
both sides at the bottom of the louver assembly (see
figure 7). Once the screws are removed, the panel
can be pivoted upwards allowing full access to the
front facing condenser (see figure 8). Vacuum or
brush any dirt, lint or dust from the finned condenser
coil, the compressor and other cooling system parts.
If significant dirt is clogging the condenser fins, use
compressed air to blow this clear. Care should be
taken not to bend any of the condenser fins, as this
will reduce performance and compressor life.
Lower louver assembly and replace the screws to hold
it in place.
VI. b - HINGE REPLACEMENT:
Both the door and hinge can be easily removed from
the cabinet. To remove the door, remove the screw at
the bottom of the upper hinge. Inside the upper hinge
there is a small pin screw which secures the door in
place. Remove this with a flat head screwdriver and
the door can then be lifted off the hinge. To remove
the door-half of the hinge from the door, slide hinge
cover downward and then remove the three Phillips
head screws which secure the hinge in place on the
door.
To remove the cabinet-half of the hinge, remove the
three Phillips head screws which hold it in place. On
all units, the top hinge(s) contains a microswitch for
controlling the interior lighting.
To reassemble the hinge reverse the previous proce-
dure.
VI. c - REPLACING THE GASKETS:
To remove the gasket to be replaced, grasp it firmly
by one corner and pull it out. Before attempting to
install a new gasket, both the unit and the gasket it-
self must be at room temperature. Insert the four cor-
ners first by using a rubber mallet (or hammer with a
block of wood). After the corners are properly inserted,
work your way towards the center from both ends by
