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
and bottom mounted condensate evaporator are boxed
and strapped inside to prevent damage. If the unit is
equipped with optional locks the 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 Spacesaver
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. c - INSTALLING LEGS OR CASTERS:
6” high stainless steel legs are supplied standard for
all Traulsen Spacesaver 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
unit 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 counter­clockwise 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.

III. b - PACKAGING:
All Traulsen Spacesaver 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 3/4” socket
wrench. Avoid laying the unit on its front, side or
back for removal of the pallet.

All exterior metal surfaces are protected from scratch­ing during manufacturing and shipping by a plastic
covering. This should be removed prior to installa­tion.

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.

Fig. 1

Please note that Traulsen Spacesaver 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.

III. INSTALLATION (continued)

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. e - INSTALLING THE CONDENSATE EVAPORATOR:
A bottom-mounted electric condensate evaporator is
normally supplied on all self-contained models. This
is shipped in a cardboard carton secured to the cabi­net interior, and must be installed prior to use.

To install a bottom-mounted electric condensate
evaporator (see figure 3).

After the cabinet has been uncrated and the legs/cast­ers attached, locate the four (4) 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, on the other.
Screw the “U-Trap” (UR30LT only) or 90 degree elbow
joint (all other Spacesaver models) into the drain line
located on the rear of the cabinet and then screw the
drain extension into the U-Trap or elbow joint.

A remote model is normally 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. f - REMOTE INSTALLATION:
Remote models are supplied without compressors,
solenoid valves, etc. The correct voltage, amp listing,
refrigerant and BTU’s 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 adhering to good prac­tice and local regulations. See section “III. e” for in­formation concerning condensate removal for remote
models.

III. g - 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. h -

POWER SUPPLY:
It is recommended that the supply voltage 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 recommended.
Size wiring to handle indicated load and provide nec­essary overcurrent protector in circuit.

III. i - 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. j - 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.

The bottom mounted electric condensate evaporator
of your Traulsen Spacesaver should be cleaned occa­sionally to keep it clear of dirt and debris.
