V. CARE & MAINTENANCE
V. 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 clean-
ing 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 remove the front louver assembly.
To remove this, lift the louver assembly out of the lower
cradle and then slide it down away from this out of the
top bracket. 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.
After cleaning replace the louver assembly.
V. 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. To remove the door half
of the hinge from the door, slide hinge cover off and
then remove the three Phillips head screws which se-
cure 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.
To reassemble the hinge reverse the previous proce-
dure.
V. c - REPLACING THE GASKETS:
Before attempting to install a new gasket, both the unit
and the gasket itself must be at room temperature. To
replace a gasket, first lift-up the gasket to expose the
door liner mounting screws. Remove the Phillips head
screws which secure the interior door liner. Next, re-
move the door liner, and the gasket to be replaced. Then,
align the new gasket with the door and replace the door
liner. Insert the Phillips head screws into the door liner
holes and tighten to secure both the gasket and door
liner to the door.
WARNING: DISCONNECT ELECTRICAL POWER
SUPPLY BEFORE CLEANING ANY PARTS OF THE
UNIT.
