has been taken in crating this product to protect against
damage in transit.
CASTERS:
To install legs or casters, slide leg or caster into the caster chan-
nel from the side of the unit without the refrigeration system.
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 file a freight claim. There is a fifteen (15) day limit
to file 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.
To adjust the legs or casters, loosen the two bolts and move
leg or caster to desired location, spacing between leg or caster
not to exceed 39 inches. Leg or caster on each end of the unit
can not exceed 8 inches from the end of the cabinet.
NOTE: Traulsen recommends to position legs or casters under
the mullion when possible.

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 door stay
open feature at 1200 (self-closing feature operates up to
900). The door must be able to open a minimum of 900 in
order to make use of the maximum clear door width. Al-
low a minimum of 12 inches (high) above the cabinet for
proper air circulation.
III. d-CORD & PLUG:
All self-contained models are shipped standard with a NEMA
5-15P plug and 9 foot cord . Select only a dedicated electrical
outlet for power source.
III. b-PACKAGING:
Your Traulsen unit is shipped from the factory bolted to a
sturdy wooden pallet in stretch wrapped material.
o not cut or remove the round grounding
prong from the plug. Do not use an extension cord.
III. e-POWER SUPPLY:
Most exterior stainless steel surfaces have a protective
vinyl covering to prevent scratching during manufactur-
ing, shipping and installation. After the unit is installed in
place of application peel, remove and discard the covering
from all surfaces.
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.
To remove the wooden pallet, first if at all possible, we
suggest that the cabinet remain bolted to the pallet dur-
ing all transportation to the point of final installation. The
bolts can then be removed with a 1/2” socket wrench.
Avoid laying the unit on its front, side or back for removal
of the pallet.
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).
NOTE: Traulsen does not recommend laying the unit on
its front, side or back. If you must, please allow the unit to
remain in an upright position for 24 hours before plugging it
in so that the compressor oils and refrigerant may settle.

IV. OPERATION
V. CARE & MAINTENANCE
IV. a-QUICK CHILLER OPERATION:
V. a-CLEANING THE CONDENSER/FILTER:
The most important thing you can do to insure a long,
reliable service life for your Traulsen is to regularly clean
the condenser coil and filter.
The Quick Chiller does not require manual defrosting. During
normal operation, a Quick Chiller 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, utilizing hot gas from the refrigeration system. The
controller is preset at the factory for six equally spaced defrost
cycles within each 24-hour period. The control will read “dEF”
and the green snowflake icon will be illuminated.
The microprocessor control will notify you through a
“CLN-FIL” message when the condensing temperature
of the refrigerator reaches 140 degrees F or greater. If
the condensing temperature reaches 160 degrees F
the compressor will automatically turn off . When the
temperature drops below 140 degrees F the compressor
will restart and when the temperature drops below 120
degrees F the alarm will reset.
SNOWFLAKE ICON

Disconnect electrical power supply
before cleaning any parts of the unit.
To clean the condenser/filter, first disconnect electrical
power to the cabinet and remove the front louver as-
sembly. To do so, place hands under the louver panel
and pull out and up to get louver panel off bracket of the
unit. (See diagram below, image shown with optional
drawer(s).
At the start of a Quick Chiller defrost cycle, the compressor,
condenser fan and evaporator fan shut off. The hot gas relay
will be energized, this will energize the hot gas solenoid valve
thru the normally open contacts and the condenser fan circuit
will be de-energized thru the (normally closed contacts), and the
compressor will restart. When the evaporator coil sensor reaches
400 F the coil is fully defrosted or if the maximum time of defrost
duration (20 minutes) is reached (which ever comes first) then
the defrost hot gas relay is de-energized. The condenser fan
restarts and the hot gas solenoid valve closes, The compressor
system returns to the cooling mode. Total refrigeration system
operation is then resumed (green snowflake icon goes out) and
the display will show def for an additional 10 minutes then return
to reading the inside cabinet temperature. The evaporator fan(s)
are delayed from starting at the termination of the defrost cycle
and will automatically resume by time or temp delay (5 minutes
or 300 F coil sensor temperature, whichever comes first ).
Proceed to vacuum or brush any dirt, lint or dust
from the finned condenser coil/filter, the compressor and
other cooling system parts. If significant dirt is clogging
the condenser fins or filter, use compressed air to blow
this clear. To replace the louver assembly reverse the
process.
During Quick Chiller defrost operation, heat is confined to the coil
enclosure to prevent any significant rise in temperature within the
food zone. The fan delay control 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 terminated
defrost at 20 minutes in the event of sensor failure. This setting
should never be tampered with, without first consulting Traulsen’s
Technical Service department at 800-825-8220.

V. b-REPLACING THE GASKETS:
VI. a-DOOR:
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 below for proper gasket placement).
Your Traulsen Full Size Undercounter Quick Chiller model door
is field re-hingeable. If re-hinging is required, please contact our
in-house service department at 800-825-8220 for instructions.
NOTE: The gasket may appear too large, but if it is in-
stalled as indicated above it will slip into place.

V. c-CLEANING THE CABINET SURFACES:
Disconnect electrical power supply
before cleaning any parts of the unit.
Exterior stainless steel should be cleaned with warm wa-
ter, 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 sur-
face. Do NOT use cleansers containing chlorine, such
as bleach, 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 or spills, use baking soda and water
(mixed to a 1 tablespoon baking soda to 1 pint water
ratio).
A stainless steel polish is recommended for shining of
unit.

Customers can set up to 4 different defrost lockout periods. The lockout prevents the unit from going into a defrost
cycle during peak kitchen use. Note: The 24-hour clock must be set for this feature to operate correctly.
5) Communication Ability
A NAFEM Data Protocol (NDP) compliant RS-485 serial communications port is available to interface with data collec-
tion software (by others). All microprocessor control equipped models are capable of communicating within a NAFEM
Data Protocol network if provided with an optional Gateway Hub (available from Traulsen). The actual communications
software is available from a number of third party software vendors.
6) Anti-Condensate Door Perimeter Heater Control
The “No-Sweat” feature is an energy savings system that allows the customer to adjust the percent of time for the door/
drawer heater to be “On” as needed for the prevailing ambient conditions (from 0 - 100% of the time each day). It is
used to prevent condensation from forming around the perimeter of the drawers. The factory default setting is 100%.
Adjust this set point down to a point just before condensation forms to save energy.
