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 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 without first
obtaining written permission (return authorization).

III. INSTALLATION

III. a - LOCATION:
Select a proper location away from extreme heat or cold.
Allow enough clearance between the unit and the side
wall in order to allow the doors to fully open.

III. b - PACKAGING:
Unit is shipped from the factory strapped to a sturdy
wooden pallet and protected by wood crating. The
crating is attached to the pallet with several screws.
These should first be removed to avoid scratching the
unit when lifting off the crating.

Most exterior surfaces have a protective vinyl covering
to prevent scratching during manufacturing, shipping,
and installation. Remove after install and discard.

To remove the roadshow cabinet from the wooden
pallet start by cutting free the nylon bands. Next,
remove the screws attaching the two metal hold down
brackets to the skid. Slide them out of the caster
channel to remove, thus releasing the roadshow
cabinet from the skid.

NOTE: DO NOT LAY THE UNIT ON ITS SIDE DURING
TRANSPORTATION OR INSTALLATION.

III. c - CORD & PLUG:
An attached cord & plug is provided, shipped coiled
inside the compressor compartment (secured by a
nylon strip). For your safety and protection, this includes
a special three-prong grounding plug. Under no
circumstances should you ever remove the round
grounding prong from the plug.

III. d - 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 for the
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 amp
requirements on the unit’s serial tag).

III. e - WIRING DIAGRAM:
Refer to the wiring diagram on page 22 for any service
work performed on the unit. Should you require a new
one, please contact Traulsen Service at (800) 825­8220, and provide serial number of the unit involved.

III. f - CLEARANCE:
To assure optimum performance of your seafood
display cabinet the condensing unit MUST have an
adequate supply of air for cooling purposes. The
operating location must have 31” minimum clearance
in front of both the customer and operator side louvers.

Select a working location away from extreme heat or
cold. The seafood display cabinet is designed to

operate in temps of 86°F (30°C) or less. Locate the unit

so that air drafts (such as heat, A/C or ventilation) do
not blow on or over the seafood display area.

III. g - ADJUSTING SUPPORTS:
Unit includes 6 factory installed casters, 2 with brakes.
For ease of mobility only the centerline casters are fixed.
To set the brake, using your foot simply push this down
into the locked position. Push up to release.

Adjust the caster location by loosening the two bolts at
the base of each caster (see fig. 2), then slide this along
the mounting channel into the desired position. Tighten
the two bolts to resecure the caster.

NOTE: When adjusting the caster

location please note that these

must always be installed towards

the four corners of the unit, as

well as the center, for proper

cabinet support and mobility.

Select only an appropriate dedicated 20 amp outlet.

To prevent cord and/or
plug damage always
secure the entire cord
on the supplied cord
wrap during transport
(see fig. 1).

Fig. 1

Fig. 2

NOTE: Cabinet is designed to be pushed from the left or
right side for easy mobility. Pushing the cabinet from
either the front (customer side) or back (operator side)
can result in damage to the center set of casters.

IV. OPERATIONS

IV a. ICE & PRODUCT LOADING GUIDELINES:
Ice is not required for proper operation, but if used it
should be loaded only up to the level of the lowest air
baffles with product loaded no higher than the rail
perimeter, indicated by load level labels (see fig 3).

IV b. PERIODIC ICE MELT REMOVAL:
In the event ice is used, the seafood display cabinet is
designed to retain a significant amount of water (from
the inevitable melting) below the display area. Up to 5
gallons of water can be held, and so may need
occasional draining during the day. A float indicator is
provided at the front of the cabinet to notify when
draining is required (see fig. 4).

Fig. 4

To drain the water...
Open the hinged louvered service door that covers the

system end of the unit. It is on the same side as the
refrigerated base doors. Pull it to open. A two foot
flexible hose is provided to facilitate water removal.

Open the valve by rotating the drain handle 90° so that

the handle is in line with the pipe. This will allow the
water to drain out. When the water stops draining, close
the valve and close the louvered service door.
Dispose of the water in an appropriate manner.

IV c. CLEANING THE DISPLAY AREA:
CAUTION: The power should be removed from the unit
by unplugging the power cord from the power source
before doing any cleaning or servicing of this unit.

For The Plastic Sneeze Shield

1) Remove the power from the unit.

2) Remove the plastic sneeze shield pieces by
sliding out of their holders.

3) Remove screws holding the front panels to those
on the side. Push canopy forward to remove from
rear cross brace retaining brackets.

4) Wash the parts with a solution of mild dish soap
and water and a soft cloth. Dry with a soft cloth.

CAUTION:

The use of any soap with chemicals
(ex. Windex, 409, etc.) will cause the
acrylic material to permanently blur.

5) Reinstall the sneeze shield pieces in the rear
cross brace brackets.

For The Display Area

1) Remove the power from the unit.

2) Locate the unit so that the system end of the unit

is located near an appropriate floor drain.

3) Open the louvered service door and position the

enclosed hose over the floor drain.

4) Rotate the red handle on the main drain valve so

that it is in line with the pipe. When you do this
the residual condensate and ice melt will spill out.

5) Remove the ice pans.

6) Remove any cross bars (running front to back) and

the two long support bars (running left to right).

7) Carefully remove the two sections of air baffles by

folding down the vertical member and lifting the
assemblies out of the unit. Care should be taken
not to hit or damage the fan blades.

8) Carefully lift the fan blades off their bearing pins

by holding the fan and lifting straight up. Place
the fan blades in a safe location. They will be
cleaned separately.

9) The display area can now be washed with a hose,

cloth or other means available. All of the water
used will come out of the main drain. Care should
be taken not to hit the fan bearing pins with any
hard objects. These are permanently installed.

10) After the unit is washed, dry with a squeegee,

towels, or other means. Using a clean rag wipe the
bearing pins clean and dry.

11) Replace the cleaned and oiled fan blades (see

procedure following) on the pins.

12) Reinstall the parts in the reverse order, steps 7-2.

13) Close the main drain valve by rotating the red

handle so that it is positioned across the pipe.

CAUTION:

Failure to close the drain pipe will result in the

condensate and ice melt water dripping

onto the floor the next time the unit is used.

V. CARE & MAINTENANCE (cont’d)

VI. OTHER

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

Avoid the use of strong detergents and gritty, abrasive
