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.
You should carefully inspect your 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 the damage. A
freight claim should be filed immediately. If damage is subsequently
noted during or immediately after installation, contact our customer
care team to le a freight claim. There is a fteen (15) day limit to le
freight damage with the carrier. Under no condition may a damaged
unit be returned to Traulsen without first obtaining written permission
(return authorization). You may contact Hobart/Traulsen customer care
at 800-333-7447 to request a return or file a claim.
III. INSTALLATION
III. a - LOCATION:
Select a proper location for your unit, away from extreme heat or cold.
Allow enough clearance between the unit and the side wall in order to
make use of the stay open feature at 1200 (self-closing feature operates
up to 900). The door(s) must be able to open a minimum of 900 in order
to make use of the maximum clear door width.
NOTE: Do not install the cabinet without legs, casters or front
ventilated utility base.
III. c - INSTALLING/ADJUSTING LEGS OR CASTERS: (continued)
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’s.
Thread optional casters into the threaded holes on the bottom of the cabinet in
the same way. Casters with brakes should be installed at the front.
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/ADJUSTING LEGS OR CASTERS:
6” High legs are supplied standard for all Traulsen compact undercounter
and prep table units. These are shipped from 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
and prep table models.
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.
NOTE: 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 FOR DOOR MODELS:
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. The shelf clips have a small
projection on top which holds the shelf position and prevents it from slipping
forwards. After installing shelf clips on pilasters, place shelves on clips.
III. e - CORD & PLUG:
All UHT, ULT, UPT & UST models are supplied with a cord and 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.
III. h - CUTTING BOARD ASSEMBLY-UPT/UST:
On sandwich prep tables, the cutting board may require assembly at
the site.
Place cutting board on cabinet, properly align & install three screws to
secure in place. The cutting board is field reversible, reverse process
to reverse cutting board.
Note: The lid(s)/cover(s) are installed at the factory. No assembly
required.
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, see page 1). 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 over current protector in circuit (see amperage requirements on the unit’s serial tag).
III. g - 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. INSTALLATION (continued)
IV. OPERATION (continued)
III. i - INSTALLING THE STAINLESS STEEL TOP-UHT:
All 27”, 32, 48, and 60” wide compact undercounter models can be
supplied with an optional stainless steel top. This must be installed
on-site, to do so please follow the directions below.
1. Peel Off backing and install foam tape (provided) around entire
perimeter of the top of the unit.
2. A flange is assembled underneath at the front of the counter top.
This flange has two screw holes. Screw the two 1/4-20x5/8” screws
(provided through the holes in this front ange into the threaded holes
in the front of the top edge of the unit.
3. Using the five 10-16x1/2” screws provided, screw the bottom of the
rear cover plate to the upper rear of the cabinet.
4. If the optional polyethylene cutting board top is provided, there are
four threaded pins which screw into the four threaded holes in the work
top. The four holes in the polyethylene cutting board top fit around the
heads of the four pins.
IV. b - TEMPERATURE CONTROL:
The temperature is set at the factory but local conditions may necessitate slight
adjustment.
The temperature control shown in below is located on the front side of the evaporator housing. To adjust, turn the adjustment screw with a screwdriver a small
amount at a time; turning clockwise lowers the temperature. An “OFF” position
is fully counterclockwise and interrupts power to the compressor and condenser
fan only, not the entire refrigerator.
ULT32 freezer model is equipped with a knob that has a number ranging from 0
to 9. Turning the knob clockwise lowers the temperature, turning the knob counterclockwise raises the temperature. O is the “OFF” position. The temperature
range of adjustments is -5 to 5 F degrees.
IV. c - DEFROST CONTROL:
Frozen food storage cabinets are equipped with a defrost timer that provides a 20
minute defrost cycle every 6 hours (four defrost cycles per day).
IV. OPERATION
IV. a - PRESTART CHECKS:
The compressor must float freely before connecting to electrical power.
The compressor motor is provided with rubber vibration isolator mounts
(no springs). No bolts need to be loosened. Check all exposed refrigeration lines to make sure they are not dented or kinked. Check for tubing
shifts due to shipping that would cause operating noise, wear, or leaks.
Check that condenser fan rotates freely.
The refrigeration system should be checked for proper operation before
product is stored in the cabinet.
