Traulsen Freezer Manual Defrost: Care and Maintenance Instructions

V. OPERATION VI. CARE & MAINTENANCE

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 UNIT.

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
