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.

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.

III. d - 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)

III. e - ROLL-IN MODEL INSTALLATION:
Roll-In cabinets set on the floor require the floor area
to be flat and level. In addition, after the cabinet is set
in place, sealant should be used around the perimeter
of the base to comply with National Sanitation Foun­dation requirements (see figure 3). After sealing the
unit, the enclosed ramp should then be installed.

A SEALANT MUST BE USED
AROUND THE PERIMETER OF THE
BASE OF CABINET AS SHOWN TO
FULLY COMPLY WITH SANITARY RE­QUIREMENTS.

A RECOMMENDED SEALANT IS
DOW CORNING SILASTIC RTV #732

Fig. 3

A stainless steel threshold ramp(s) is included to fa­cilitate rolling in racks. It is shipped wrapped in brown
paper and secured to the rack guides inside the cabi­net. To secure it in place, remove the two thumb
screws in the breaker strip near the bottom door open­ing. Next, loosen the thumb screws located along the
floor at the threshold. Place the ramp(s) on top of the
loosened thumb screws and secure tabs on each end
to breaker strips with thumb screws previously re­moved. After installing the ramp(s), it too should be
sealed to the floor.

Bumper strips are secured to the back of Roll-In mod­els with thumb screws. Loosen these and make them
finger-tight to conform with the requirements of the
National Sanitation Foundation (NSF).

III. f - INSTALLING THE CONDENSATE EVAPORATOR:
A condensate evaporator is normally supplied on all
self-contained models (remote models require provi­sion of either a floor drain or an optional condensate
evaporator). On those models with the evaporator coil
compartment located on the top of the unit, the con­densate evaporator is also secured to the top of the
cabinet. Check that the condensate pan is under the
drain tube.

Some models, such as one-section dual-temperature
reach-in refrigerator/freezers, are supplied with a bot­tom-mounted electric condensate evaporator. This is
shipped in a cardboard carton secured to the cabinet
interior, and must be installed prior to use.

After the cabinet has been uncrated and the legs/cast­ers attached, you must install the bottom-mounted
electric condensate evaporator. Locate the four (4)

III. f - INSTALLING THE CONDENSATE EVAP (cont’d):
holes on the exterior bottom towards the rear of the
cabinet. Then, using the four (4) screws provided, at­tach the mounting rails to the cabinet bottom (the end
flange is to be up and be facing towards the cabinet
rear). Next, place the heater into the heater bracket
(note the enclosed springs are only to be used when
the heater is placed on the floor). Slide heater and
bracket into the mounting rails. Plug the supplied cord
into both the heater on one end, and the electrical
outlet provided on the cabinet exterior bottom towards
the front (see figure 4). Screw the “U-Trap” on to the
drain line located on the rear of the cabinet and then
screw the drain extension into the “U-Trap.”

A remote model is normally supplied configured for
condensate to be run to a floor drain unless purchased
with a condensate evaporator. The installer is respon­sible for making the required extension to the floor
drain in accordance with good practice and local regu­lations.

III. g - REMOTE INSTALLATION:
Remote models are supplied without compressors,
solenoid valves, etc. The correct voltage, amp listing
and refrigerant are listed on the unit’s serial tag. It is
the responsibility of the installer to specify and sup­ply the correct size compressor(s) based upon this
information and on-site requirements. Refrigerant line
installation must be done in accordance with good
practice and local regulations. See section “III. g” for
information concerning condensate removal for re­mote models.

III. h - CORD & PLUG:
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. INSTALLATION (continued) V. CARE & MAINTENANCE (cont’d)

III. i - 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).

III. j - 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. k - COMPRESSOR HOLD DOWN PROVISIONS:
To protect the compressor during transit, some self­contained Traulsen models have compressors tight­ened down at the factory. The hold down bolts used
to tighten these must be loosened before operation
to allow the vibration eliminators to funtion properly.
Failure to loosen the hold down bolts could result in
refrigerant line leakage, vibration and noise. Check
the top to be sure all factory installed blocking (if used)
is also removed. Likewise, check the compressor en­closure of bottom mounted units (RFD/AFD models)
to be sure all packing is removed and that compres­sors secured to the base of condensing unit are free
to operate on their vibration eliminators.

IV. a - CLEANING THE CONDENSER (cont’d):
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

III. l - 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. CARE & MAINTENANCE

IV. 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 as sembly. To lift this, remove the

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
