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 interior fittings
have been carefully secured and the legs or casters
are boxed and strapped 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. Condenser performance
is dependent on adequate ventilation for cooling
purposes. Adequate clearance MUST be provided
for the ventilator locations underneath. There are
no clearance requirements for sides, rear, or top.

III. c - INSTALLING LEGS OR CASTERS (cont'd):
the factory inside a cardboard box which is secured
inside the cabinet. Casters in lieu of legs are supplied
as an optional accessory for all compact undercounter
models. The casters are “stem” type, and do not re­quire the use of any bolts. When ordered, casters

are shipped in a separate box.

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

Raise up and block the cabinet a minimum of 7" from the
floor and thread the legs into the threaded holes on
the bottom of the cabinet (see figure 1).

Fig. 1

NOTE: Do not install the cabinet without legs, cast­ers or front ventilated utility base.

III. b - PACKAGING:
All Traulsen units are shipped from the factory bolted
to a sturdy wooden pallet and packaged in a durable
cardboard container. The carton is attached to the
wooden skid with the use of large staples. These
should first be removed to avoid scratching the unit
when lifting off the crate.

To remove the wooden pallet, first if at all possible, we
suggest that the cabinet remain bolted to the pallet
during all transportation to the point of final installa­tion. The bolts can then be removed with a 5/8” socket
wrench by tipping or otherwise raising the unit to al­low access to them. 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 LEGS OR CASTERS:
6” high legs are supplied standard for all Traulsen
compact undercounter units. These are shipped from

Thread optional casters into the threaded holes on
the bottom of the cabinet in the same way (se e f igu re 2).
Casters with brake should be installed at the front.

Fig. 2

Level the cabinet using a level or pan of water in the
bottom of the cabinet. On units with legs, turn the
adjustable feet in or out to level the cabinet side-to-side
and front-to-back. Units with casters should be placed
on level floors.

III. INSTALLATION (continued)

III. c - INSTALLING LEGS OR CASTERS (cont'd):

Please note that Traulsen units are not designed to
be moved while on legs. If the unit requires moving,
a pallet jack or forklift should be used to prevent
damage.

III. d - SHELF CLIPS:
Shelves and shelf clips are shipped with the unit.
For each shelf, insert four (4) shelf clips into the
pilaster slots at the same height (Fig. 3). The shelf
clips have a small projection on top which holds the
shelf in position and prevents it from slipping forwards.
After installing shelf clips on pilasters, place shelves
on clips.

Fig. 3

III. h - CLEARANCE:
It is important for the proper operation and longevity
of your Traulsen unit that it have adequate provisions
underneath for air supply to the compressor. There
are no clearance requirements for the sides, rear or
top.

NOTE: Do not install the cabinet without legs, casters
or a front ventilated utility base.

III. i - OPTIONAL UTILITY BASE:
An optional utility base is available, in lieu of legs
or casters, for models UHT27, ULT27, UPT276 &
UPT279 only. To install this, follow the directions
below see (figure 4):

III. e -

CORD & PLUG:
All UHT, ULT & UPT models are supplied with a cord &
plug attached. It is shipped coiled at the bottom of
the cabinet, secured by a nylon strip. For your safety
and protection, all units supplied with a cord and plug
include a special three-prong grounding plug on the
service cord. Select only a dedicated electrical outlet
with grounding plug for power source. NOTE: Do not
under any circumstances, cut or remove the round
grounding prong from the plug, or use an extension
cord.

III. f - POWER SUPPLY:
The supply voltage should be checked prior to con­nection to be certain that proper voltage for the cabi­net wiring is available (refer to the serial tag to deter­mine correct unit voltage). Make connections in ac­cordance with local electrical codes. Use qualified
electricians.

Use of a separate, dedicated circuit is required. Size
wiring to handle indicated load and provide necessary
overcurrent protector in circuit (see amperage require­ments on the unit’s serial tag).

Fig. 4

1. Place utility base in final installed location.
NOTE: The front of the utility base must be
oriented towards the front. Fastener locations
are provided for anchoring utility base to floor,
if desired; fasteners are not provided.

2. Place unit on top of utility base so holes
underneath are aligned. The plug cord must be
routed from the bottom right rear corner of the
unit through a slotted hole in the utility base.
Assemble the strain relief (provided) around the
electric cord and route it through the slotted
hole in the utility base.

III. g - WIRING DIAGRAM:
Refer to the wiring diagram for any service work per­formed on the unit. Should you require one, please
contact Traulsen Service at [phone], and pro­vide the model and serial number of the unit involved.

III. INSTALLATION (continued)

III. i - OPTIONAL UTILITY BASE (cont'd):

3. Assemble four 1/2 –13 bolts and lockwashers
through holes in utility base and into threaded
holes in bottom of unit where legs or casters
would be installed.

4. Place rear cover on back of utility base so D-slot
captures the groove of the strain relief. Attach
rear cover with six 8 – 18 self-tapping screws. If
floor receptacle is provided underneath utility
base for unit to plug into, strain relief will not be
used and rear cover should be installed up-side­down so D-slot is covered.

5. Install front grill on front of stacking base with
eight 8 – 18 self-tapping screws.

If your unit comes with a utility base, we recommend
securing the base to the floor. Place the unit in its
final installed position, then apply a bead of NSF
approved silicone sealant around the bottom.

III. j - OPTIONAL STACKING KIT:
Models UHT27 and ULT27 only have the option of
a stacking kit, in which no more than two (2) units
can be stacked one on top of the other.

III. j - OPTIONAL STACKING KIT (cont'd):

8. Install front grill on front of stacking base with
eight 8 – 18 self-tapping screws.

1. Install legs, casters or utility base on bottom unit
following instructions elsewhere in this manual.
Place bottom unit near final installed location
leaving access to rear for further assembly.

2. Place stacking base on top of bottom unit. NOTE:
The front of the stacking base must be oriented
towards the front.

3. Assemble two 1/4 – 20 x 5/8" screws through front
mounting flange of stacking base into the
threaded holes in the front of the top edge of the
bottom unit. Assemble five 10 – 16 x 1/2" screws
through rear flange of the stacking base into the
upper rear of bottom unit.

4. Place upper unit on top of stacking base so holes
underneath are aligned.

5. Assemble four 1/2 – 13 bolts and lockwashers
through holes in stacking base into threaded
holes in bottom of upper unit where legs or
casters would be installed if unit were to sit
directly on the floor.

6. The plug cord must be routed from the bottom
right rear corner of the upper unit through a
slotted hole in the stacking base. Assemble the
strain relief (provided) around the electric cord
and route it through the slotted hole in the
stacking base.
