IV. i - ERROR MESSAGES:

In the event of an error message, please refer below for troubleshooting:

E2- Appears if the control settings are not properly stored in memory. To correct, check all settings and correct if necessary (see section IV. a).

EE- Appears if the EEPROM has been corrupted. Con- tact an authorized service agent to replace the control.

CL- Appears if calibration mode has been entered. To correct, shut off the power supply to the unit for at least five seconds. If after doing so the CL message still apppears, contact an authorized service agent to replace the control.

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.
