II. RECEIPT INSPECTION

III. INSTALLATION (continued)

All Traulsen products are factory tested for perfor­mance and are free from defects when shipped. The
utmost care has been taken in crating this product to
protect against damage in transit. All legs or casters
are boxed inside to prevent damage.

You should carefully inspect your Traulsen unit for
damage during delivery. If damage is detected, you
should save all the crating materials and make note
on the carrier’s Bill Of Lading describing this. A freight
claim should be filed immediately. If damage is sub­sequently noted during or immediately after installa­tion, contact the respective carrier and file a freight
claim. Under no condition may a damaged unit be re­turned to Traulsen & Co. without first obtaining writ­ten permission (return authorization).

III. INSTALLATION

III. a -

LOCATION:
Select a proper location for your Traulsen unit, away
from extreme heat or cold. Allow enough clearance
between the unit and the side wall so that the door (s)

may open a minimum of 90°.

III. b - PACKAGING:
All Traulsen VPS units are shipped from the factory
on a sturdy wooden pallet and packaged in a durable
crate with staples. These should first be removed to
avoid scratching the unit when lifting off the crate.
Avoid laying the unit on its front, side or back for re­moval of the pallet.

NOTE: Traulsen does not recommend laying the unit
down on its front, side or back. However, if you must
please be certain to allow the unit to remain in an up­right position afterwards for 24 hours before plugging
it in so that the compressor oils and refrigerant may
settle.

III. c - INSTALLING CASTERS:
Six (6) 8” high casters are supplied standard for all
VPS units. These are shipped from the factory packed
inside a cardboard box, contained within the unit.

WARNING: THE CABINET MUST BE BLOCKED AND
STABLE BEFORE INSTALLING LEGS OR CASTERS.

To install the legs or casters, first raise and block the
unit a minimum of 9” from the floor. The casters slide
into the two leg channels on the front and back of the
cabinet. These are fully adjustable along the unit’s
entire length to allow for avoiding floor obstructions,
such as drains and outlet boxes. Be certain that all
casters are tightly secured; to do this, tighten the two
bolts located at the base of each caster assembly.

NOTE: Casters or legs must be installed towards the
four corners of the unit, as well under the compress-

III. c - INSTALLING CASTERS (cont’d):
or compartment, for proper support. See drawing on
page 6 for correct placement.

III. d - INSTALLING LEGS:
Optional legs are installed in the same manner as cast­ers (see figure 1). When the unit is set in its
finalposition it is important for proper operation that
the unit be leveled. The legs are adjustable for this
purpose.

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 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 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 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.

EE- Appears if the EEPROM has been corrupted. Con­tact 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.

To reassemble the hinge reverse the previous proce­dure.

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, re­move 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.
