III. c - REFRIGERATION SYSTEM INSTALLATION:
All Traulsen blast chillers, with the exception of model TBC5, require
the use of a oor drain or oor mounted condensate evaporator for
condensate removal. Refer to Section IV. h of the blast chill owner’s
manual for more information.
Remote refrigeration installation requirements apply only to models
TBC1H/TBC1HR and TBC2H/TBC2HR. A remote condensing unit, operating on R-404A refrigerant, is required for Blast Chill operation on
these models. The remote condensing unit(s) should be capable of
providing 18,700 BTU/hr @ -10°F evaporator temperature and 90°F
ambient.
Air-cooled and water-cooled remote condensing units are available
from Traulsen as an optional accessory. Please note that these
should be adequate for any installation within a 25 foot radius from
the cabinet. Beyond this distance, the actual capacity of the remote
condensing unit and line sizing may change depending upon the
length and layout of the connecting piping from the remote condensing unit to the Blast Chiller. These utilize a 1/2” liquid and 1-1/8”
suction lines. Proper specication of the remote condensing unit
needed and line sizing should be dened by a qualied refrigeration
engineer or technician, based on the jobsite installation needs.
The low pressure cut-out of the remote condensing unit should be
adjusted to obtain an evaporator coil temperature NO LOWER THAN
-15°F. If the length of the connecting piping is 40 feet or less, the
condensing unit low pressure cut-out settings will be approximately
15 +/- 2 PSIG cut-out and 25+/- 3 PSIG cut-in.
For more information please contact the factory.

VI. COMPONENT FUNCTION
Compressor Pumps refrigerant through refrigeration lines and components.
Condenser Fan Draws air across condenser coil to aid in removing heat from the refrigerant and
moves air across compressor to aid in cooling the compressor.
Dual Pressure Control Low side monitors suction pressure at compressor. Shuts compressor OFF when
(TBC1H & TBC2H only) low pressure setting is reached (cut-out). Allows compressor to run when
pressure rises to cut-in setting.
High side monitors discharge pressure at compressor. Shuts compressor OFF
when high side pressure setting is reached (cut-out). Allows compressor to run
when pressure returns to cut-in setting.
The differential is the difference in pressure between open and closed states of the
pressure switch.
Start Capacitor Wired in series with the start windings to help start compressor motor.
Run Capacitor Continually in circuit to help compressor motor during operation.
Thermal Overload Removes power from compressor if the internal temperature of the compressor
becomes too high (auto reset).
Start Relay Senses current of run winding of compressor motor. Normally open contacts
close when run winding draws a high amperage at start and brings the start
capacitor and start windings into the circuit. As the motor reaches operating
speed (less amperage through run winding), the normally open contacts open and
removes the start capacitor and start windings from the circuit.
Evaporator Fan Draws air from the cabinet and moves air through the evaporator coil.
Defrost Heater Defrosts evaporator coils and prevents water droplets from evaporator coil from
freezing before they can drain to the condensate pan. Operates only during
defrost cycle.
Air Temperature Sensor Monitors air temperature inside the cabinet.
Coil Temperature Sensor Monitors the suction line temperature at evaporator during defrost cycle.
Food Temperature Probe Monitors temperature of food product.
Solenoid Valve Normally closed. When energized, allows refrigerant to ow from receiver to
evaporator coil.
Door Perimeter Heater Prevents condensate on door frame.
Controller Performs the following functions:
a) Displays all data for the current mode of operation.
b) Cycles refrigeration system to maintain cabinet temperature.
c) Monitors power failures.
Power Supply Boards Provides DC voltage to control system.

OF REFRIGERANTS. BE CERTAIN THE WORK AREA IS
WELL VENTILATED. SAFETY GOGGLES AND GLOVES
SHALL BE WORN SINCE REFRIGERANTS MAY CAUSE
INJURY TO THE SKIN.
Introduction - Refrigeration reclaiming equipment is
required. Our goal in system evacuation is to remove
all the non-condensables possible. No evacuation
method will remove 100% of the moisture and air from
within the refrigeration circuit. Because of this, guidelines and methods must be developed and adhered
to ensuring only harmless amounts of contaminants
remain in the system.
GUIDELINES
• Use only a two stage vacuum pump (2 CFM or
greater) and electronic micron gauge.
• Set output valve on nitrogen bottle to equal
appropriate pressure, for the design rated
refrigerant at 100 degrees F on the P/T chart.
• Evacuate from high and low sides of the system.
• No chemical additive or alcohols are to be used to
“dry up” a system.
• Blow down of system with DRY NITROGEN prior to
evacuation is acceptable and many times
desirable. See “System Clean-Up.”
• Evacuate to 200 microns of mercury.
1. Access the refrigeration system.
2. Connect low (BLUE) side of gauge manifold to
schrader valve on compressor access line and
high (RED) side of gauge manifold to schrader
valve on lter/drier line.
a) If any leaks are detected, repair leak and re
check for additional leaks.
b) If no leaks are discovered, evacuate system
as outlined in section “VIII. M”.
NOTE: Install a permanent high side access port for
future system diagnostics.
11. Charge the system and check for proper
operation.
NOTE: If there is no high side access, install a
permanent sweat on tap.
3. Connect center line of gauge manifold to
vacuum pump.
4. Turn vacuum pump on and open both sides of
gauge manifold.
5. Pull a vacuum to 200 microns.
6. Charge system and check for proper operation.

VIII. SERVICE PROCEDURES (cont’d)
IX. m - CHARGING SYSTEM:
WARNING: DISCONNECT THE ELECTRICAL POWER
TO THE MACHINE AND FOLLOW LOCKOUT/TAGOUT
PROCEDURES.
WARNING: THIS PROCEDURE REQUIRES THE USE OF
REFRIGERANTS. BE CERTAIN THE WORK AREA IS
WELL VENTILATED. SAFETY GOGGLES AND GLOVES
SHALL BE WORN SINCE REFRIGERANTS MAY CAUSE
INJURY TO THE SKIN.
1. Access the refrigeration system.
2. Be sure the refrigeration system is checked for
leaks and properly evacuated before charging as
outlined under “LEAK CHECK” and
“EVACUATING SYSTEM.”
3. Connect high side of gauge manifold to the
liquid line (make certain both valves on the gauge
manifold are closed).
NOTE: Put initial charge to system through the high
side to prevent liquid refrigerant from reaching the
compressor.
4. Connect refrigerant bottle to center connection
of gauge manifold (check the refrigerant bottle to
conrm direction for liquid).
5. Purge the hose from the refrigerant tank to the
manifold gauge.
6. Open high side of gauge manifold and allow
appropriate amount of refrigerant to ow into the
refrigeration system.
7. Disconnect the hose from the receiver valve
8. Reconnect power to the unit and check for
proper operation and high pressure leaks.
NOTE: Adjust charge as needed based on superheat
and operating pressures. Through low side of system.
IX. n - SYSTEM CLEAN UP/INTRODUCTION (cont’d):
WARNING: DISCONNECT THE ELECTRICAL POWER
TO THE MACHINE AND FOLLOW LOCKOUT/TAGOUT
PROCEDURES.
WARNING: THIS PROCEDURE REQUIRES THE USE OF
REFRIGERANTS. BE CERTAIN THE WORK AREA IS
WELL VENTILATED. SAFETY GOGGLES AND GLOVES
SHALL BE WORN SINCE REFRIGERANTS MAY CAUSE
INJURY TO THE SKIN.
If a compressor burn-out or failure has occurred, DO
NOT install a new compressor until the clean-up procedure has been completed.
If a massive moisture contamination or POE oil breakdown has occurred, remove the old compressor as
outlined in section “IX. E”, drain the oil and hold for
replacement.
1. Recover refrigerant based on current EPA
guidelines.
2. Remove lter/drier and metering device.
NOTE: In POE oil applications, it should always be
assumed that the metering device is restricted aftre a
contamination. These devices CAN NOT be ushed
clean and reused.
3. Flush high and low sides of refrigeration system
with nitrogen to displace any trapped oil and
contaminates.
4. Reassemble refrigeration system to include
compressor, 032 size liquid line drier and new
metering device.
NOTE: The use of low ow nitrogen through the system while welding is mandatory to prevent oxidation/
carbon plating that will lead to further contamination.
9. Disconnect power to the unit and replace any
panels or covers removed.
10. Reconnect power to the unit.
IX. n - SYSTEM CLEAN UP/INTRODUCTION:
When a refrigeration system is accessed in servce
some degree of system clean up is required. There
are two levels of clean up:
• BASIC - Conduct procedure as outlined under
“EVACUATING SYSTEM” and incorporating a
drier change, this is recommended only when
system exposure is limited.
• MASSIVE - The use of Polyol Ester (POE) oil in
systems using R-134a and R-404A, as well as in
many other applications, require that every
system failure be treated as a massive clean-up.
NOTE: The use of a suction drier is recommended
when moisture contamination is present. The suction
drier should be removed within 48 hours of installtion
to prevent further performance issues. Also install a
new liquid line drier for maximum system clean-up.
5. Replace new oil into the compressor.
6. Purge system with nitrogen for 5 minutes.
Pressure should be applied to the high side and
allowed to vent through the port on top of the
compressor.
7. Evacuate system for 30 minutes.
8. Repeat steps 5 and 7 two additional times.
NOTE: The nal vacuum should be 200 microns or less.
9. Charge the system and replace any panels or
covers removed.
10. Reconnect power and check for proper opertion.

VIII. SERVICE PROCEDURES (cont’d)
IX. o - REPLACING DOOR GASKETS:
WARNING: DISCONNECT THE ELECTRICAL POWER
TO THE MACHINE AND FOLLOW LOCKOUT/TAGOUT
PROCEDURES.
NOTE: Before attempting to install a new gasket, both
the unit and the gasket itself should remain at room
temperature for at least 48 hours (especially in a low
temperature area).
1. To begin removing the gasket to be replaced,
grasp it rmly by one corner and pull it out.
2. Insert the new gasket by the four corners rst by
using a rubber mallet (or hammer with a block of
wood).
3. 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 below diagram for
proper gasket placement).
NOTE: The gasket may appear too large, but if it is
installed as indicated above it will slip into place.
