Determining Big Dipper Series

There are several physical identifiers as well as a serial number which may assist an owner or inspector in determining the series of a Big Dipper unit.

Determining Series by Serial Number

The easiest way to determine the series is by using the serial number.  In most cases the serial number is on a label located beneath the inlet pipe of the unit.  The Electrical Assembly number on the center module of more recent series does not quickly identify the series.  If all you can find is this electrical assembly number, call Thermaco directly to determine the serial number and/or series.

Reading a Big Dipper Serial Number

1.  The first part of the serial number signifies the model of the unit.  Look for the number and letter combination occuring before the first decimal.

For example:

200.3257BD-1 is a W-200-IS because of the 200 that occurs before the first decimal.

750-AST.0812UC-1 is a W-750-AST because of the 750-AST that occurs before the first decimal.

Various models can include any of the following:

W-150-IS, W-200-IS, W-250-IS, W-350-IS, W-500-IS, W-750-IS, W-1250-IS,

W-300-AST, W-500-AST, W-750-AST, W-1250-AST, W-1000-AST, W-250-AST, W-1000-AST-ULTRA

2.  The numbers following the decimal in the serial signify the Series of the unit 

Pre-2000 Series Unit

If the numbers following the decimal begin with 0 or 1 AND is a three number the unit is a pre-2000 series unit.

For example:

200.013AD-1 is a pre-2000 Series unit

2000 Series Unit

If the numbers following the decimal begin with 2,3 or 4 AND is a four digit number the unit is a 2000 Series unit.

200.2345FD-1 is a 2000 series W-200-IS

350.4536QH-1 is a 2000 Series W-350-IS

NOTE: A distinguishing factor for 2000 Series and pre-2000 series units is that the electrical components are located on the side of the unit. Pre-2000 series are not enclosed and 2000 series are enclosed in a stainless steel box.

5000 Series Unit

If the numbers following the decimal begin with 5 AND is four digits the unit is a 5000 Series unit.

For example:

500.5003RG-1 is a 5000 Series W-500-IS

NOTE: The 5000 Series units have a lid that is three pieces hinged together with a black plastic cover over the sump and electrical components on the center of the lid.

6000 Series Unit

If the numbers following the decimal begin with 6 or 7 AND is four digits, the unit is a 6000 Series unit.

For example:

750.6027RK-1 is a 6000 Series W-750-IS

NOTE: The 6000 Series units have a lid that is three separate pieces (no longer hinged together) with a black plastic cover over the sump and electrical components on the center of the lid.

8000 Series Unit

If the numbers following the decimal begin with 8 or 9 and is four digits, the unit is an 8000 Series unit.

For example:

200.8467VE-1 is an 8000 series W-200-IS

250.9023VD-1 is an 8000 series W-250-IS

NOTE: The 8000 Series units have a lid that is three separate pieces with injection molded plastic covers over the sump and electrical components (warm gray / tan in color) with a stainless steel base on the center module.

14000 Series Unit

If the numbers following the decimal begin with 14 OR 15 AND is a five digit serial number, the unit is a 14000 Series unit.

For example:

200.14158VG-1 is a 14000 series W-200-IS

250-AST.14006VG-1 is a 14000 series W-250-AST

NOTE: The 14000 Series units have a lid that is three separate pieces with injection molded plastic covers over the sump and electrical components (warm gray / tan in color). Also, the lid is stainless steel on either side of the center module. The base of the center module is injection molded plastic.

21000 Series Unit

If the numbers following the decimal begin with 21 AND is a five digit serial number, the unit is a 21000 Series unit.

For example:

200.21169YA-1 is a 21000 series W-200-IS

250-AST.22345ZD-1 is a 21000 series W-250-AST

NOTE: The 21000 Series units have a lid that is three separate pieces with injection molded plastic covers over the sump and electrical components (warm gray / tan in color). Also, the lid is stainless steel on either side of the center module. The base of the center module is injection molded plastic. There is NO timer on this unit. There is a power indicator light and a push button switch.

40000 Series Unit

If the numbers following the decimal begin with 40 AND is a five digit serial number, the unit is a 40000 Series unit.

For example:

200.40001ACI is a 40000 Series W-200-IS

Determining Series by Physical Characteristics

In most cases, the series can also be determined by the location of the center module, the type of skimming mechanism used, and the materials used in its composition.

Pre-2000 series: The electrical components are located on the side of the unit. They are exposed and not encased.  The tank is made entirely of stainless steel.

2000 Series: The electrical components are located on the side of the unit. They are enclosed and encased in stainless steel.  The tank and enclosure or made entirely of stainless steel.

5000 Series: The electrical components are located on the top of the unit, covered by a black, injection molded cover. They are in the center of the lid, connected to the wings with hinges. There is a mechanical timer on the center module that can be adjusted to increase or decrease the run time of the unit. Each center module of electrical components has its own serial number designated with the letters EA.  The tank includes a rotationally molded black interior tank and stainless steel wrap.

6000 Series: The electrical components are located on the top of the unit, covered by a black, injection molded cover. They are in the center of the lid, which is comprised of three separate pieces. There is a mechanical timer on the center module that can be adjusted to increase or decrease the run time of the unit. Each center module of electrical components has its own serial number designated with the letters EA.  The tank includes a rotationally molded black interior tank and stainless steel wrap.

8000 Series: The electrical components are located on the top of the unit, inside a warm grey/tan injection molded cover with a stainless steel base. They are in the center of the lid, which is comprised of three separate pieces. There is a mechanical timer on the center module that can be adjusted to increase or decrease the run time of the unit. Each center module of electrical components has its own serial number designated with the letters EA.  The tank includes a rotationally molded black interior tank and stainless steel wrap.

14000 Series: The electrical components are located on the top of the unit, inside a warm grey/tan injection molded cover with an injection molded base. They are in the center of the lid, which is comprised of three separate pieces. There is a mechanical timer on the center module that can be adjusted to increase or decrease the run time of the unit. Each center module of electrical components has its own serial number designated with the letters EA.  More recent versions of this unit have jog and heater switches on the side and back of the unit, respectively.

21000 Series: The electrical components are located on the top of the unit, inside a warm grey/tan injection molded cover with an injection molded base.. They are in the center of the lid, which is comprised of three separate pieces. There is no mechanical timer, but instead a power indicator light and push button switch are visible. Each center module of electrical components has its own serial number designated with the letters EAS.  Attached to the bottom of the center module is an additional L-shaped piece which acts as a grease sensor.

40000 Series: The electrical components are located on the top of the unit, inside a warm grey/tan injection molded cover with an injection molded base.
