III. INSTALLATION
III. a - INSTALLING THE PAN CHILLER:
Self-contained units must be installed with sucient air circulation
for the condensing unit. Venting must include provisions for both air
intake and exhaust. Failure to provide adequate ventilation may cause
severe compressor damage, and will void warranty.
Both self-contained and remote units require a counter cut-out that
is 3/8 inch (0.3175cm) larger than the overall outer dimension of the
pan chiller. Refer to the specication sheet for your particular unit.
IV. a - ELECTRICAL CONNECTIONS:
Refer to the wiring diagram shipped with the unit located inside the compressor compartment or on the back of the unit.
IV. b - CORD CONNECTED UNITS SELF-CONTAINED
MODELS:
Plug the unit into a properly sized outlet. See serial tag located
inside lower storage cabinet for proper circuit sizing.
WARNING: THIS MACHINE IS PROVIDED
WITH A THREE-PRONGED GROUNDING PLUG. THE OUTLET
TO WHICH THIS PLUG IS CONNECTED MUST BE PROPERLY GROUNDED. IF THE RECEPTACLE IS NOT THE PROPER
GROUNDING TYPE, CONTACT AN ELECTRICIAN.
V. PRESTART CHECKS
V. a - DEFROST TIME CLOCK SETTINGS:
Never apply power to a Traulsen unit without setting the time
clock to the correct time of day. (Note: All time clocks are
preset at the factory to turn the pan chiller “o at 12:00 midnight and back on at 5:00 a.m.” unless otherwise instructed
by customer).
III. b - REFRIGERATION LINES REMOTE MODELS:
WARNING: REFRIGERATION LINES ARE SHIPPED UNDER PRESSURE.
USE CAUTION WHEN OPENING LINES.
Location of the refrigeration lines varies depending on installation
needs. The suction line is 3/8” copper tubing and is marked “Suction”.
The supply line is 1/4” copper. See “Electrical Connections” section for
wiring instructions.
A control box, expansion valve, solenoid valve, time clock and temperature controller, is supplied with the drop-in. All drop-in units are
shipped with this control box loose. Refrigeration lines and power
supply must be attached to this box then routed to the drop-in.
Cut refrigeration tubing with tube cutter (not a hacksaw) and de burr
end of tube. De grease tubing prior to eld connection. Use Silfos 5%
for refrigerant line brazing. 50/50 or cold solder is not acceptable.
If no holding charge is evident upon opening lines, contact Traulsen
Parts and Service Department at (800) 825-8220 immediately.
On self-contained units, the time clock is located on the
compressor compartment housing.
To set the time of day, rotate the disc in the direction of the
arrows (clockwise rotation) to align the hands to the correct
time of day (see page 3).
To change time clock setting, the tripper pins must be recongured. Each pin on the time clock represents 15 minutes.
Tripper pins pulled out away from center of time clock represent refrigeration o. Tripper pins pushed toward center
indicate refrigeration on. If system runs only during normal
working hours and food has been removed from pan chiller
at night, the time clock must be set to shut pan chiller o at
closing time and to turn on one hour prior to putting the food
in the pan chiller the next day (see page 3).
For system charge, follow remote refrigeration system manufacturer’s
instructions.

V. b - LEAVING FOOD PRODUCT IN THROUGHOUT THE
NIGHT:
If leaving the food product in the pan chiller overnight, defrost time
clock needs to be set to cycle o and on throughout the night. Time
clock must be set to run for 15 minutes on and 60 minutes o consistently until the night cover is removed the next day. To change the
setting, set the pins to desired cycle times. Each tripper pin represents 15 minutes. Tripper pins pulled out away from center of time
clock represent refrigeration o. Tripper pins pushed toward center
indicate refrigeration on. Make sure time clock is set to correct time
of day (see below).
V. c - TEMPERATURE CONTROL SETTINGS:
All temperature settings are preset at the factory but local
conditions may necessitate slight adjustments.
On both self-contained and remote units, the temperature
control marked should be set at 23º F (-5°C) with a 3º F dierential. The operating display range should read between 20ºF
(-6.6°C ) and 28º F (-2.2°C ). The temperature control settings
are “locked” to avoid unauthorized adjustments. Therefore,
an authorized service technician must make adjustments to
the set point.
VI. OPERATION
VI. a - PAN CHILLER:
Note: Pan chiller system Must BE periodically shut down for
proper defrost and functioning of the unit (see instructions
on pages 2-3 for defrost time clock settings ).
To insure proper food temperatures are maintained in exposed insert pans, the following conditions are required per
NSF Standards:
1. No direct air blowing on food product from other equipment in the kitchen (max air velocity 50 FPM).
Plastic wrap should be placed over exposed food prior to closing
the night cover to help prevent condensation from getting into the
food. The night cover must be closed if food is being left in the pan
chillers overnight.

2. Room ambient temperatures of 86ºF (30°C ) and relative
humidity of 50% or less around working area of pan chiller.
3. Food sits a minimum of 1 inch below top of insert pan.
4. All shelving mounted over insert pans (with heated equipment above it) must be insulated.
5. Occasional stirring of certain foods may be required in
order to maintain consistent temperatures.
6. Some food products chill faster than others i.e., lettuce,
diced tomatoes, etc. Double pans will help prevent over
chilling.
7. For remote refrigerators with pan chiller systems, it is imperative that the existing refrigeration equipment must be
sized properly and in good working condition.
VI. b - SHUTDOWN FOR EXTENDED PERIODS:
For an extended period of time, disconnect the electrical
power. As soon as the divider bars have defrosted, wipe out
the pan chiller cavity.

VIII. CONDENSING UNIT SELF-CONTAINED
VIII. a - CONDENSING UNIT SELF-CONTAINED MODELS:
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY
BEFORE CLEANING ANY PARTS ON THE UNIT.
The condensing unit coil must be cleaned regularly on self-contained
models for optimal performance. The operating environment will
aect the required frequency of cleaning. However, coils should be
cleaned a minimum of once every three months. Air must be able to
freely circulate through the condenser. Unit performance and operating eciency are signicantly aected by the amount of air passing
through the condenser. Condenser ns that are clogged with dirt
and debris greatly reduce required airow. Failure to keep the coil
ns clean may cause premature compressor failure, which will not
be covered by warranty.
Drain
A second drain located below the fan assembly in the pan
chiller must also be properly maintained and functional. (See
Fig. 5). To access this drain, remove the fan shroud and fan
housing assembly. (A 7/16” hex socket is required to remove
the fan assembly cap screws). Clear drain of dirt and debris
so that condensate can ow freely. This drain is provided for
condensate run o from defrost cycle.
Always run both drain separately to the oor sink.
The condensing unit is located at the bottom of the unit. To access
the condenser coil, remove the slotted access panel to the right of the
controls. The panel is held in place with 6 Philips head sheet metal
screws. Carefully clean dirt and lint from the condenser coil using a
vacuum cleaner or soft brush; do not use a wire brush. These units do
not have a removable lter. Replace slotted access panel. Reconnect
electrical supply.
