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.
Door keys will be attached to the handle with a nylon
strip. The handle is protected by an easily removable
nylon netting.

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 in order to make

use of the door stay open feature at 120° (self-closing
feature operates up to 90°). The door(s) must be able
to open a minimum of 90° in order to make use of the

maximum clear door width available.

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.

Most exterior stainless steel surfaces have a protec­tive vinyl covering to prevent scratching during manu­facturing, shipping and installation. After the unit is
installed in place of service, remove and discard the
covering from all surfaces.

III. c - INSTALLING LEGS OR CASTERS:
6” high stainless steel legs are supplied standard for
all Traulsen reach-in and pass-thru units. Casters in
lieu of legs are available as an optional accessory for
the same models. These are shipped from the factory
packed inside a cardboard box which is strapped to
one of the shelves. Remove the nylon strap and open
the box, it should contain either four (4) legs or four
(4) casters and sixteen (16) bolts.

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

To install the legs or casters, first raise and block the
reach-in a minimum of 7” from the floor. For install­ing legs, thread the legs into the threaded holes on
the bottom of the cabinet (see figure 1). Be certain
that all legs are tightly secured (legs and casters
should be tightened to 300 inch/pounds, max). When
the unit is set in its final position, it is important for
proper operation that the unit be level. The legs are
adjustable for this purpose, turn the bottom of the leg
counter-clockwise to raise it, clockwise to lower it.
Level the unit from front to back as well as side to side
in this manner, using a level placed in the bottom of
the cabinet.

Fig. 1

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. For installing casters, the casters are “plate”
type, and require the use of four (4) bolts each to se­cure them firmly to the cabinet bottom at each corner
(see figure 2). The caster bolts are tightened using a
1/2” socket wrench.

Threaded Holes

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 3/4” socket
wrench. 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.

SHELF PINS:
The unit is supplied with shelves and shelf pins in­stalled. Check all shelf pins to assure they are tight­ened down as they may have come loose during ship­ping. Rotate the pins clockwise until they are secured
against the side of the cabinet.

III. INSTALLATION (continued)

IV. OPERATION

CORD & PLUG:

III. e ­Most self-contained models are supplied with a cord
& plug attached. It is shipped coiled at the top 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).

IV. b - FREEZER NORMAL OPERATION (continued):
factory for six equally spaced defrost cycles within each 24­hour period.

At the start of a freezer defrost cycle, both the compressor
and evaporator fans are OFF. The microprocessor control
will read “dEF” (see figure 3). The electric heater (attached
to the coil) is energized. When a temperature device affixed
to the coil senses 70°F (models with electric defrost), the
coil is fully defrosted and the compressor operation is re­sumed, defrost heaters are automatically turned off. The
coil fans are delayed from starting at the termination of a
defrost cycle. Fan operation is automatically resumed, or
they can also be started by a time or temp delay (whichever
comes first). In case of temp delay, it uses the same coil
sensor and starts at 32°F. The total refrigeration system op­eration is then resumed.

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. h - CLEARANCE:
In order to assure optimum performance, the condens­ing unit of your Traulsen unit MUST have an adequate
supply of air for cooling purposes. Therefore, the
operating location must either have a minimum of 12”
clearance overhead of the condensing unit or allow
for unrestricted air flow at the back of the unit. Clear­ance of at least 12” above is required in order to per­form certain maintenance tasks.

IV. OPERATION

IV. a - CONVERTIBLE CABINET - INTENDED USE:
A convertible cabinet is a reach-in freezer which, with
the use of a key switch, can change itself to operate at
refrigerated temperatures. This two temperature abil­ity allows the operator to maximize either their refrig­erated or frozen storage space as needed, providing
them with additional flexibility in order to manage
changing menus and product types.

IV. b - FREEZER NORMAL OPERATION:
During normal operation, a freezer continuously circulates
below freezing cabinet air through the coil. The coil requires
a periodic defrosting for proper operation. This is accom­plished by an automatic, time activated, temperature/time
terminated, defrost program. The controller is preset at the

-3-

SET

FREEZER

Fig. 3

During freezer defrost operation, heat is confined to the coil
enclosure to prevent any significant rise in temperature
within the food zone. The fan delay controls function upon
termination of a defrost cycle is two-fold. First, to prevent
blowing warm air into the food storage area. Second, to
prevent any condensation on the defrost coil from being
blown into the food storage area.

The Microprocessor control is set from the factory to termi­nate defrost at 20 minutes in the event of a sensor failure.
This setting should never be tampered with, without first
consulting the factory.

IV. c - USING THE CONVERTIBLE FREEZER:
The default setting as delivered from the factory is for

operation in normal freezer mode (0 to -5°F). How-

ever, operation can be changed to refrigerated tem-

peratures (36-38°F) by inserting the key into the face

mounted “CONVERSION KEY SWITCH ” and turning
this 90 degrees clockwise. Turn the key back 90 de­grees counter-clockwise (to the 12 O’Clock position)
to resume normal freezer operation.

V. CARE & MAINTENANCE

WARNING:

DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF THE UNIT.

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 accummulation. 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 lift up the front louver as­sembly. To lift this, remove the two screws located on
both sides at the bottom of the louver assembly (see
figure 6). Once the screws are removed, the panel
can be pivoted upwards allowing full access to the
front facing condenser (see figure 7). 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.

Lower louver assembly and replace the screws to hold
it in place.

Screws

V. b - HINGE REPLACEMENT:
Both the door and hinge can be easily removed from
the cabinet. To remove the door, remove the plug at
the bottom of the top hinge. Inside the hinge there is
a small screw which secures the door in place. Re­move this with a flat head screwdriver and the door
can then be lifted off the hinge. To remove the door
portion of the hinge from the door, lift off the hinge
cover and then remove the three Phillips head screws
which secure the hinge in place on the door. To re­move the cabinet portion of the hinge, remove the three
Phillips head screws which hold it in place. On solid
door units, the top hinge(s) contains a microswitch
for controlling the interior lighting.

To reassemble the hinge reverse the previous proce­dure.

V. c -

REPLACING THE GASKETS:
To remove the gasket to be replaced, grasp it firmly
by one corner and pull it out. Before attempting to
install a new gasket, both the unit and the gasket it­self must be at room temperature. Insert the four cor­ners first by using a rubber mallet (or hammer with a
block of wood). After the corners are properly inserted,
work your way towards the center from both ends by
gently hitting with a mallet until the gasket is com­pletely seated in place (see figure 8 for proper gasket
placement).

V. CARE & MAINTENANCE (cont’d)

V. d - CLEANING THE EXTERIOR:
Exterior stainless steel should be cleaned with warm
water, mild soap and a soft cloth. Apply with a damp­ened cloth and wipe in the direction of the metal grain.

Avoid the use of strong detergents and gritty, abra­sive cleaners as they may tend to mar and scratch the
surface. Do NOT use cleansers containing chlorine,
this may promote corrosion of the stainless steel.

Care should also be taken to avoid splashing the unit
with water, containing chlorinated cleansers, when
mopping the floor around the unit.

For stubborn odor spills, use baking soda and water
(mixed to a 1 TBSP baking soda to 1 pint water ratio).

VII. MICROPROCESSOR CONTROL

°F °C

Your new Traulsen R or A Series Convertible Refrigerator or Freezer is equipped
with an electronic microprocessor control, which precisely regulates opera­tion. It is supplied from the factory completely ready for use. See pages 5 thru
14 for more information.

V. e - CLEANING THE INTERIOR:
For cleaning both stainless steel and anodized alumi­num interiors, the use of baking soda as described in
section “V. d” is recommended. Use on breaker strips
as well as door gaskets. All interior fittings are remov­able without tools to facilitate cleaning.

VI. MISC. OPERATIONS

VI. a - ADJUSTING THE SHELVES:
For shelves mounted on pins, first select the desired
location and remove the white plastic covers in the
interior back and sides by rotating them counter-clock­wise. Remove the shelf pins by rotating them counter­clockwise. Install the pins in the desired location by
rotating clockwise. Make sure the pin is securely tight­ened down. Do not over tighten. Slide the shelf into
its new position, and replace the white plastic covers
into the holes vacated by the shelf pins.
