II. GENERAL INFORMATION

II. a - APPLICABLE MODELS:

This manual applies to the following Traulsen models:

RBC50 Undercounter Blast Chiller Models

RBC100 Reach-In Blast Chiller Models

RBC200 Roll-In Blast Chiller Models

RBC200RT Roll-Thru Blast Chiller Models

PLEASE NOTE: This manual refers to the above mod-

els built after June 2003, equipped with the Smart Chill

control. For information regarding models built prior to

that date please contact the factory.

In addition, models UBC50, RBC400 and RBC400RT are

not covered by the procedures listed in this manual.

Please contact the factory for more information.

II. b - INTRODUCTION:

Blast Chillers are food processing refrigerators de-

signed for rapid chilling of product from 135 F to 37 F

in approximately 90 minutes, for reheating and/or

serving at a later time.

These models aid in preserving food quality, texture

and nutritional value, in addition to enhancing food

safety. All of the information, illustrations and

specifications contained within this manual are based

on the latest product information available at the time

of printing.

II. c - OPERATION:

Refer to the instructions contained in the Owner’s

Manual, form number TR35850, for specific operating

instructions.

II. d - CLEANING:

Detailed cleaning instructions are included with each

unit; however, special care MUST be given to the

condenser coil(s). These must be cleaned WEEKLY.

This surface must be kept free of dirt and grease for

proper system operation. This can be done with a

vacuum cleaner using a brush attachment, or a stiff

brush or whisk broom. Care must be taken not to

damage the condenser coil fins. For more information

please refer to section “IV. a - IV c” of the Blast Chill

Owner’s Manual.

II. e - WIRING DIAGRAMS:

Refer to the wiring diagrams on pages 20 thru 22 for

any service work performed on the unit. Should you

require another copy, please contact Traulsen Service

at (800) 825-8220, and provide the model and serial

number of the unit involved.

II. f - TOOL REQUIREMENTS:

For most jobs a standard set of hand tools, a VOM with

AC current tester, electrically conductive field service

grounding kit, along with a temperature tester or

thermometer are adequate. However in some cases the

following additional tools may be required as well:

II.f - TOOL REQUIREMENTS (CONT):

•Refrigeration Reclaiming Equipment

•Acetylene Torch

•Nitrogen Bottle With Gauges

•Refrigeration Gauge Manifold

•Dial-a-Charge

•Valve Core Removal Kit

•Vacuum Pump

II. g - THE SERIAL TAG:

The serial tag is a permanently affixed sticker on

which is recorded vital electrical and refrigeration

data about your Traulsen product, as well as the

model and serial number. This tag is located at

the front top corner on the right interior wall on all

blast chiller models. An example is shown below.

III. c - REFRIGERATION SYSTEM INSTALLATION:

All Traulsen blast chillers, with the exception of model

RBC50, require the use of a floor drain or floor

mounted condensate evaporator for condensate

removal. Refer to “Section III. h” of the blast chill

owner’s manual for more information.

Remote refrigeration installation requirements apply

only to models RBC200 and RBC200RT. A remote con-

densing unit, operating on R-404A refrigerant, is re-

quired for Blast Chill operation on these models. The

remote condensing unit(s) should be capable of pro-

viding 18,700 BTU/hr @ -10 F suction and 90 F ambi-

ent at the evaporator coils of the Blast Chill section.

4 HP air-cooled and 3 HP water-cooled remote con-

densing units are available from Traulsen as an op-

tional accessory, but please note that these are rated

for use only within a 25 foot radius of the cabinet.

III. c - REF’N SYSTEM INSTALLATION (CONT):

Actual capacity of the remote condensing unit and line

sizing will depend on the length and layout of the con-

necting piping from the remote condensing unit to the

Blast Chill unit. These utilize a 1/2” liquid and 1-1/8”

suction lines. Proper line sizing should be defined by a

qualified refrigeration engineer or technician.

The low pressure cut-out of the remote condensing unit

should be adjusted to obtain an evaporator coil

temperature NO LOWER THAN -

the connecting piping is 40 feet or less, the condens-

ing unit low pressure cut-out settings will be approxi-

mately 15 +/- 2 PSIG cut-out and 25+/- 3 PSIG cut-in.

For more information please contact the factory (800-

825-8220).

IV. SMART CHILL CONTROL

IV.a –SEQUENCE OF OPERATION:

a.1 –Control Revision Numbers

There are multiple versions of the Smart Chill Control

V1.08 - V2.11. Largely troubleshooting on all versions

will be the same.

a.2 –System Idle:

The Smart Chill control is meant to maintain a median

operating temperature of 37F - 40F when in idle (no

active batches). During this time only the

“Maintenance” or holding system is active with the

exception of the RBC200 which runs the Blast system

ever other cycle. Anytime the display shows to be at

the “Main Menu” the system is in idle.

a.3 –Chill Cycle:

When a standard chill cycle or batch is started the unit

will maintain a median temperature of 10F-14F until all

product is chilled to 37F, if using food probes, or until

preset time is complete. During this time both the

“Maintenance” and “Blast” systems will be active.

a.4 –Holding:

Once all product reach 37F or below, or the preset time

is completed, the unit will begin what is called a

“Holding” mode. During “Holding” the unit will again

maintain 37F - 40F but both systems continue to

operate because of the known product load. Once the

operator removes the product and acknowledges the

removal of product via the control the system returns

to idle or the “Main Menu”.

a.5 –Defrost:

Models RBC100, RBC200, and RBC200RT have electric

defrost. Models RBC50 have hot gas defrost. On all

units defrost is scheduled to occur every 3 hrs and

terminates at a 50F coil temperature. RBC100, RBC200

and RBC200RT have a max defrost duration 40 minutes

while the RBC50 has a max defrost duration of 15

minutes. Once a defrost is initiated it cannot be

overridden or terminated by any method other than

meeting control parameters (time or temperature). The

Smart Chill control WILL NOT initiate a defrost cycle

during a chill cycle. Rather it will flash DEF REQD in

the top left portion of the display screen when a defrost

is required during a chill cycle. Once the chill cycle

completes the unit will then initiate a defrost. The

Smart Chill control WILL initiate a defrost during a Hold

mode.

For more information regarding additional operating

modes and conditions please reference the Owner’s

Manual.

IV.b –Manual Defrost:

To initiate a manual defrost the system must be in

idle and at the main menu. Once a defrost is

initiated it cannot be overridden and terminated by

IV.b –MANUAL DEFROST (CONT):

any method other than meeting control parameters

(time or temperature).

1. From the “MAIN MENU” select “MORE”

2. Select “DEFROST”

3. Select “START” the unit should now be in a defrost.

IV.c –PRINTING CONTROL DATA:

c.1 –Cycle/Batch Data:

All batches run “BY TEMP” or using “EASY START”

will be stored in memory. At any time we can access

this data and reprint Cycle/Batch data using the

following instructions.

1. From the “MAIN MENU” select “MORE””

2. Select “Print”

3. Select desired probe to retrieve data from, 1,2, or, 3,

then select date and time of Cycle/Batch

4. Select “PRINT”. A full log of the selected

Cycle/Batch should print.

c.2 –12 Hr Data Log:

The Smart Chill control records data from all inputs and

outputs in five minute increments. At any time this

data can be retrieved in the form of a 12 Hr data log. A

12 Hr data log is a useful tool when troubleshooting

intermittent errors or when all other avenues have been

exhausted. You may analyze the data yourself using

the reference on page 33, Data Log Diagnostics

Explanation or you may contact Traulsen Technical

Support and we will analyze it for you. Ph. 800-825-

8220 Fax. 817-740-6737. To print a data log follow the

instructions below.

1. From the “MAIN MENU” select “MORE”

2. Select “Print”

3. Select “PRINT: CYCLE” will change to “PRINT:

DATA”

4. Select appropriate date and time to begin the 12 Hr

log

5. Select “PRINT” a 12 Hr log should begin to print via

the record printer

IV.d –SERVICE MENU ACCESS:

d.1 - Introduction

The service menu can be used to assist in

troubleshooting a Blast Chiller. There are two ways to

access the service menu (see d.2 & d.3). Once the

service menu has been accessed all relay outputs

should de-energize. A technician may then cycle

components individually for troubleshooting purposes.

d.2 –Access Service Menu (75)
