Diagnostics/repair
B. Overview
TE-3000 features
The intent of this manual is to assist the user of the TE-3000 in the
general installation, operation, maintenance, and simple field repair of the
unit. This operations manual contains sections dealing with descriptions
of equipments, unpacking and installation, general front panel operations,
remote control/response operations, preventative maintenance, and
simple failure analysis and fault isolation.
Detailed diagnostics and repair should be performed in conjunction with
or solely by CANNON® Instrument Company. Please consult
CANNON® Instrument Company for further assistance beyond the
content of this manual.
The TE-3000 is a state of
the art, microprocessor
controlled and
thermoelectrically
cooled, constant temperature liquid bath. It is
totally self-contained in
two stackable bench-top
units which together
occupy a foot print less
than 15 by 20 inches. The
TE-3000 does not
contain any fluorocarbons or refrigeration
components and the only
moving parts are four
ball-bearing cooling fans
and a long-life vibratory
air pump. It can obtain
any temperature between
+30 degrees to -30
degrees Celsius and
remain stable at that
temperature within .01
degrees under normal
operating conditions.

Temperature control
Calibration
Networking/communication
The principals of operation for this instrument are the latest in science
and technology. Custom-developed Peltier Cells are arranged on the back
and sides of the bath vessel. Newly designed high density air heat
sinks on the outer surfaces (hot side) of these Peltier Cells are cooled by
muffin fans running at half of their rated voltage. The bath liquid (2.5
liters) is constantly circulated by recycled bath vapors to ensure uniform
temperature distribution and stability. The temperature is controlled (both
heating and cooling) with a custom designed 16 bit digital pulse width
modulator running at a very high frequency.
The TE-3000 can be calibrated to any temperature reference standard for
any desired Celsius or Fahrenheit temperature. The controls for entering
the target (desired) temperature and the calibration at this temperature are
very simple and straight forward. The instrument remembers these
calibration corrections for every possible temperature as well as the latest
desired temperature so that upon power-up, the bath will
adjust to these last known and entered parameters.
The TE-3000 was designed for the future with built in capability for
remote control and networking with a new family of instruments. With
this remote interface capability, it is now possible to obtain quality
assurance data via a computer network. The TE-3000 was also designed
to ensure that its capabilities may be easily changed or updated with new
operating firmware via a remote download over this same network.

CANNON® TE-3000 Thermoelectric Constant Temperature Bath
Version 1.1c — May, 2005; CANNON® Instrument Company
2139 High Tech Road • State College, PA 16803 • USA
Sections A through C in the previous chapter dealing with item descriptions should be read prior to this section. The final placement for the TE3000 should be a level, strong, and stable bench or table surface.
Occasional access to the rear of the unit should be conveniently permitted. The bath requires adequate ventilation for the integral cooling fans so
a space of at least eight inches should be provided between the rear and
both sides of the TE-3000 and any wall or other obstruction. A clearance
6
Figure 3:
TE-3000 rear view with alignment bolt highlighted
area on the right side of the unit is necessary to allow access to the rear
pump switch. An electrical service MAINS power outlet must be located
within nine feet of the TE-3000.
The lower Control Chassis should be placed on the table first followed by
the upper Bath Vessel Housing which is placed on top of the Control
Chassis. The rear mounted alignment bolt on the top rear of the lower
Control Chassis must mate with the hole in the alignment bracket on the
bottom rear of the upper Bath Vessel Housing (see Figure 3). A 1/4-20
hex nut is provided to secure this mating arrangement and should only be
finger-tightened.
D. Liquid and pneumatic connections
The pneumatic connections on the TE-3000 provide the bath agitation
and subsequent stirring by recirculating the bath vapors. Two silicon tube
assemblies are provided which have plastic quick-connect bayonet style
connectors on their ends. These tubes are connected from the air in/out
connections on the bottom Control Chassis to the air out/in connections
on the upper Bath Vessel Housing. There are female connectors on both
ends of one hose and male (black o-ring visible) connectors on both ends
of the other hose. The hose with the female connectors mates with a male
connector on the lower chassis and a male connector on the upper housing.
The hose with the male connectors mates with a female connector on the
lower chassis and a female connector on the upper housing. They all secure
with an insertion and a 1/8 turn lock.
E. Platform/pump assembly
The platform and pump assembly may be completed with the following
items provided by CANNON®:
Overflow Platform & assembly screws (2)
Reciprocating Pump
Pre-cut tubing (approx. 11", 6" & 3" lengths)
CANNON® TE-3000 Thermoelectric Constant Temperature Bath
Version 1.1c — May, 2005; CANNON® Instrument Company
2139 High Tech Road • State College, PA 16803 • USA
If the rear platform is not yet attached to the bath unit, you should attach
it using the two 6-32 screws provided. The tabs which will hold the
overflow jar in place should be facing upward.
7
Procedure
1. After the platform is securely in place, attach the 11" tubing to the
bath intake at the top rear of the bath unit by pushing the tubing
firmly over the intake nozzle. Then attach the other end of the tube to
the top of the Reciprocating Pump (next to the electric connector
cable) in the same way.
2. Remove the plastic nipple adaptor from the opposite end of the
Reciprocating Pump and insert the pump end into the small hole on
the Overflow Platform so the pump rests on the platform.
3. Reattach the nipple adaptor removed in Step 2 (this holds the unit in
place).
4. Attach the electric connector cable from the Reciprocating Pump to
the receptacle marked PUMP on the Control Unit. To connect the
cable, make sure to align it correctly with the Bath Unit female
connector (tab upwards), then push until the cable connection
“clicks” into place.
5. Attach one end of the 6" tube to the bottom connection on the
Reciprocating Pump.
6. Attach the 3" tube to the bath
unit overflow outlet located
above the Overflow Platform.
Place the Overflow Jar on the
platform, inserting the other

F. Electrical connections
Two large diameter electrical cables
deliver power from the lower Control
Chassis up to the upper Bath Vessel
Housing (see Figure 5). Both of these
cables have circular plastic power connectors on their ends. The cable with
three large rectangular pins carries DC
power to the Bath Vessel Housing from
the Control Chassis and the cable with
nine smaller circular pins carries AC
power to the Bath Vessel Housing. Both
of these cables have a male connector on
one end and its female counterpart on the
AC
Figure 5: AC/DC cable connections
other (see Figure 6). Determining which connector mates is fairly simple
but ensure a good connection by
turning the locking ring on every
plug until a small “click” is felt.
DC
Sensor connections
PUMP connections
POWER connection
The small black cable with a metal
LEMO connector carries the
temperature sensor signal from the
upper Bath Vessel Housing down
to the lower Control Chassis
(labeled PROBE). This connection is keyed and it operates as a
bayonet with a simple push in (no
twisting). The red dot on the plug
must be facing upward or insertion will not be permitted. When this connector is properly inserted, a
small “click” can be felt. Removal is accomplished with a simple pull on
the knurled section of the plug.
The small wire cable from the liquid pump with a gray plastic REDEL
connector mates with the connector on the lower Control Chassis labeled
PUMP. This connection is keyed and it operates as a bayonet with a
simple push in (no twisting). The keyway must be facing upward or
insertion will not be permitted. When this connector is properly inserted,
a small “click” can be felt. Removal is accomplished with a simple pull.
The MAINS power cord provided with the instrument will have an IEC
connector on one end and the appropriate wall outlet connector on the
other.

G. Selecting a bath liquid
9
The “Ideal” Bath Liquid
Temperature Ranges
The “ideal” bath liquid would have a low viscosity, high heat capacity,
and low vapor pressure over a wide range of temperatures. This liquid
would also have a very high flash point and be relatively inexpensive. If
the liquid were to be used in kinematic viscosity measurements where
visual observation is important, it would be clear and colorless.
Unfortunately, there is no one “ideal” liquid to use when a wide temperature range is needed. No single liquid meets all of the above requirements.
The kind of liquid used in the TE-3000 Temperature Bath depends upon
the desired temperature range of the instrument. The table below lists
several different operating ranges and the liquids suitable for use in those
ranges:
SDIUQILHTAB0003-ET
EGNARERUTAREPMET SDIUQILHTABELBATIUS
C°01+otC°03-lohoclAlyhteM
C°02+otC°01-lohoclAlyporposI
lohoclAlyhtE
CAUTION
CAUTION
CAUTION
Bath Liquid Guidelines
C°03+otC°5+sliOytisocsiVwoL,retaW
Methyl alcohol (methanol) is very close to the “ideal” liquid; it can be
used at all temperatures in the TE-3000 operating range. However,
methanol may not be suitable for some laboratories because of its low
flash point and degree of toxicity.
Isopropyl alcohol is less toxic than methyl alcohol and somewhat less
volatile. However, it becomes very viscous at low temperatures, making
it difficult to maintain good temperature control.
Silicone fluids CANNOT be used in the TE-3000 Constant Temperature
Bath. NEVER place a silicone liquid in the TE-3000.
Do not attempt to use water as a bath fluid for operation at temperatures
of 2°C or lower.
When selecting a liquid for use in the TE-3000, keep the following
guidelines in mind:

CHAPTER
GENERAL OPERATIONS
44

44
A. Filling the bath with liquid
Prior to filling the TE-3000 with liquid, you should ensure that the bath
overflow liquid reservoir, pump, and hoses are properly in place. For
detailed installation procedure, please see the previous Chapter 3.D
The TE-3000 should be filled through one of the top instrument holes
with a clear, alcohol type, liquid. This alcohol may be either wood or
grain based.
11
CAUTION
Bath volume changes
Do not use silicone fluid!
The dilution of this alcohol should be such to permit adequate stirring at
the lowest operating temperature. Excessive water dilution will cause the
liquid to appear cloudy at cold temperatures and thus impair the visibility
in the bath.
Using room temperature alcohol, carefully pour the liquid into a funnel
sitting in one of the instrument holes at the very top of the Bath Vessel
Housing. As the bath liquid approaches the very top of the bath vessel,
the overflow liquid will spill down the overflow tube into the jar.
The amount of “extra” liquid available in the overflow jar will depend
upon what temperatures you will be operating the bath. Also, some bath
liquid will be displaced by the addition of instruments and thermometers
into the bath - and thus cause the level to rise.
The bath liquid will expand if warmer than room temperatures are
desired. An empty jar at room temperature will fill up with the expanded
liquid as the temperature rises. In this case, you would only install
enough bath liquid to have the level just below the bath top edge and no
liquid in the jar. Do not overfill the bath.
CANNON® TE-3000 Thermoelectric Constant Temperature Bath
Version 1.1c — May, 2005; CANNON® Instrument Company
2139 High Tech Road • State College, PA 16803 • USA
The bath liquid will contract if colder than room temperatures are
desired. An almost full jar at room temperature will be depleted with the
compressed liquid as the temperature falls. In this case, you would fill the
bath and about half of the over flow jar with the room temperature liquid
and after the insertion of the instruments, the jar would be almost full.
The purpose of the previous explanations is to illustrate that the steady
state room temperature condition of the bath must be such that you
should never spill any liquid and this level should be maintained with
time after some of the alcohol evaporates.
12
Experience will further define the necessary levels to be maintained in
the overflow jar. But in all cases, for proper temperature control the level
of the liquid inside the bath should be about 1/2" above the top edge of
the white baffle.
B. Application of power
Prior to the application of mains power to the TE-3000, ensure that all
tubing and power connectors are properly installed between the upper
Bath Vessel Housing and the lower Control Chassis. The bath liquid
should be in place along with the overflow jar and tubing. Also be certain
that the mains voltage and frequency specified on the rear identification
label matches your mains voltage.
The power cord should have the appropriate power plug to permit
plugging the cord into the mains power outlet on the wall. The other end
contains an IEC connector which plugs into the power inlet receptacle on
the rear of the lower Control Chassis. Be CERTAIN that you are plugging into the correct mains voltage as defined on the rear panel identification label. Both front panel power switches should be OFF while this
power cord is being installed.
Turning on the TE-3000
1. Cold start
Turn on the main BATH power switch. The LIGHTS switch is operable
only if the BATH power is on. You should hear a long "beep” followed
by a short “beep” and the bath electronics will enter one of two possible
start-up procedures.
This is the normal start-up mode for the bath and it occurs when the
power was previously off for a period greater than about two seconds.
The five LEDs in the lower row of keys will turn on and then off, a short
“beep” tone will be heard, and the display on the front panel will initially
and briefly show the following:

Initiating Self Test
After this display the bath will automatically enter the self-test sequence
as specified in the following Section 4.C.
2. Warm start
This is the abnormal start-up mode for the bath and it occurs only if the
power was previously off for a period less than about two seconds, or if a
fault was detected in the microprocessor. The display will show the
following and the lights on the bottom row of the keyboard should flash
alternating.
POWER UP
Warm Start
Consult User’s Guide
If this condition is ever discovered, the BATH power switch should be
turned off. After waiting several seconds, turn the BATH power switch to
the ON position and wait for the display to indicate either a warm or cold
start again. If the bath comes up in a cold start condition and starts its
normal self-test sequence, it is possible that a momentary power interruption caused the warm start condition and no further action is required. If
the bath continues to enter the warm start condition, the user should
consult CANNON
®
Instrument Company for further assistance.

The keypad on the front panel of the TE-3000 (see Figure 8) consists of
fifteen keys - white numbers 0 through 9, a white combination “minus
sign” and “decimal point” key (-/.), a yellow SET TEMP[erature] key, a
yellow CAL[ibrate] TEMP[erature] key, a yellow MENU key, and an
orange ENTER key. The bottom row of five keys (non-numerical keys)
have the capability of being illuminated to assist the operator by indicating possible key entry choices.
All keypad lights are off during normal operation of the bath. The only
key entry possibilities at this time are the yellow keys. Depression of any
key other than a yellow key will result in a long “beep” to indicate an
improper entry. If any yellow key is depressed, the appropriate instructions are provided on the LCD and are discussed in later sections of this
manual. If no further action is taken by the operator in any menu or other
screen mode within five minutes, the display will automatically revert
back to the normal (quiescent) display as shown above.

Selecting/canceling options
The
ENTER
key
E. LED indicators
To access any of the primary keypad options, press the appropriate
keypad button once. If you make a data entry error and wish to cancel
your input sequence, press the same keypad option button again.
The ENTER key is the most-used feature on the TE-3000 keypad. You
must confirm each submenu choice and numeric input by pressing this
key.
The two LED indicators on the right side of the front panel signify the
actual control signals commanding the temperature control of the bath.
The COOLING indicator (green LED) may be viewed as a multiple
intensity light with brightness directly proportional to the degree of
cooling power applied to the solid state coolers (thermoelectric modules).
The HEATING indicator (red LED) is more simply on or off and at
warmer temperatures it will blink at one second intervals to signify that
power is applied to the internal heating element in the bath. The
HEATING indicator will be fully illuminated if the bath is commanded
to go to a temperature much warmer than the current temperature.
F. Adjusting the liquid level in the bath
Assuming that the bath has already been filled according to the instructions as provided in Chapter 4-A, the user must adjust the level of the
bath liquid as the bath temperature is decreased. Since the bath liquid
decreases in volume as the temperature decreases, the operator must add
liquid to the bath vessel to maintain proper circulation.
Maintaining bath liquid level
The level of the liquid inside the bath vessel must be maintained at a
level approximately 1/2 inch above the top edge of the rear (white)
baffle. When the liquid is adjusted to the proper level, a large number of
bubbles will be visible rising behind the baffle and causing some turbulence at the surface of the liquid. A push-button switch is provided on the
upper rear right hand side of the lower Control Chassis which when
depressed, activates the small pump next to the overflow jar which
returns the liquid from this jar back into the bath vessel.
Adequate expansion volume is provided in the expansion jar so that you
may operate at -35° Celsius with the bath liquid maintained at approximately 1/2 inch above the top edge of the baffle with the
expansion jar empty. When the bath is powered-off from this condition,
the liquid will expand in the bath vessel and overflow into the jar. The jar
is of sufficient size to accommodate all of this expansion liquid without
overflowing as the temperature slowly rises up toward room temperature.

G. Setting the target (desired) bath temperature
The setting of a new desired temperature for the bath is accomplished by
depressing the yellow SET TEMP key. The display will be changed to
the following:
Enter Target Bath
Temperature:
+_____ °C
SET TEMP to Cancel
With the cursor (dark underline character) in the first position, the user
has the option of setting a negative temperature by depressing the combination -/. key. If any numerical key is depressed in this first position, the
temperature is assumed to be positive. After this first character entry,
there are only two restrictions which apply prior to depression of the
ENTER key and they are:
1. A decimal point MAY be included as an entry. It should be preceded
by at least one number or a "0".
Incorrect settings
High-temp adjustments
2. The entered temperature must be within the operational temperature
range of the bath.
If a temperature is entered which is outside of the operational temperature range of the TE-3000, the following display will be shown on the
LCD and the ENTER key will flash.
*** RANGE ERROR! ***
Range is -43 to 33° C
or -45 to 91° F
ENTER to continue...
If the bath was previously operating at a temperature below +20° Celsius
and a new temperature is entered which is above +20° Celsius, the
operator will be instructed to remove one of the air circulation tubes on
the rear of the instrument. By disconnecting the air input hose on the rear
of the Control Chassis, the alcohol vapors cannot condense inside the air
return hose and subsequently impede the air circulation/stirring of the
bath. For this condition, the display issued to the LCD will be:
DISCONNECT AIR INPUT

If the bath was previously operating at a temperature above +20° Celsius
and a new temperature is entered which is below +20° Celsius, the
operator will be instructed to replace one of the air circulation tubes on
the rear of the instrument. By reconnecting the air input hose on the rear
of the Control Chassis, the alcohol vapors will be contained within the air
return hose and permit the operation at low temperatures. For this condition, the display issued to the LCD will be:
RECONNECT AIR INPUT

ENTER to continue...
H. Calibration at a given target temperature
The TE-3000 temperature control system permits the calibration of the
bath temperature to agree with any user supplied temperature reference
standard. The bath can be calibrated by the user whenever the bath
temperature is stable for any given TARGET temperature in degrees
Celsius or Fahrenheit.
19
BIN settings
For every whole degree Celsius and Fahrenheit, a calibration “BIN”
exists in nonvolatile memory within the temperature control system. The
“reference actual temperature” is entered by the user as the actual temperature of the bath according to the user’s temperature reference standard and is stored by the bath in this memory and will be used whenever
that particular target temperature is entered. Fractional degrees will use
the closest whole number bin. In the following example, the target
temperature is -20 degrees Celsius and the bath temperature is stable and
controlling well within +/- .01 degrees. When the CAL TEMP key is
depressed, the display will show:
Enter Actual Bath
Temp. for Bin Offset
at -20 C: +_____ °C
CAL TEMP to Cancel
With the cursor (dark underline character) in the first position, the user
has the option of entering a negative temperature by depressing the
combination -/. key. If any numerical key is depressed in this first
position, the temperature entered is assumed to be positive. After this first
character entry, there are three restrictions which apply prior to depression of the ENTER key and they are:

1. A decimal point MAY be included as an entry. It should be preceded
by at least one number or a "0".
2. The entered temperature must be within the operational temperature
range of the bath.
3. The entered actual temperature must not cause a correction in temperature greater than +/- 2.5 degrees.
Multiple or successive entries of correction for any temperature are
permissible. A newly entered corrected temperature is mathematically
20
compensated with the previously entered correction and is stored as the
latest correction.
Data entry errors
I. Menu selections
If a temperature is entered which is outside of the operational temperature range of the TE-3000 plus or minus the allowable correction factor,
the following display will be shown on the LCD:
*CALIBRATION ERROR!*

a. Clearing all temperature calibrations/offsets
Whenever a 1 is entered in the BATH TEMP OFFSET menu, the following screen is shown. This command will clear ALL of the temperature
correction “bins” for degrees Celsius AND Fahrenheit which may have
previously been set. This command is usually used prior to adjustment of
the “general bath offset”. This command may also be used if significant
differences become apparent between the user supplied reference temperature and the displayed temperature of the bath or if CAL TEMP
entries were made when the bath was not stable. Once this "clear"
command is issued, new calibration entries may be made in the CAL
TEMP menu.

The TE-3000 is equipped with a full-duplex RS-232C point-to-point
interface as well as a half-duplex RS-485 network interface. Commands
and Queries may be sent to the TE-3000 via either interface and Responses and Reports received by a master controlling computer. This
interface is configured as 8 data bits with no parity and one stop bit. The
Baud rate of the interface is configured only via the front panel menu
system and can be set at 1200, 2400, 9600, 19.2k, or 38.4k Baud. The
mode of operation, point-to-point or polled (multi-drop), can only be
configured via the front panel menu system. Time interval reports of the
actual and desired bath temperature can only be enabled if the TE-3000 is
configured in the point-to-point mode of operation.
A. Downloading firmware updates
25
The TE-3000 is capable of receiving new operational software via either
the RS-232 or RS-485 interface. If this software is updated and a new
release is issued by CANNON® Instrument Company, a diskette will be
sent to the users along with instructions on how to perform this upgrade.
Download button
A “download” push-button is provided on the rear panel of the TE-3000
which places the instrument into the download mode. When this mode is
entered, the front panel display will show the version number of both the
resident download hardware code and the version of the present operational firmware. A computer will then be required to send the new
firmware to the TE-3000.
B. Full duplex (POINT-TO-POINT) operations
The RS-232 interface is furnished for a direct connection from one TE3000 to one computer. A DB-25 connector, configured as Data Communication Equipment (DCE), is provided on the rear panel of the TE-3000.
This configuration permits a direct connection (straight through cable pins 1 through 8, & 20) from the TE-3000 to virtually any computer.
Most present day computers have a DB-9 connector which requires the
use of an adaptor or a cable with a DB-25 male connector on one end and
a DB-9 female connector on the other end. For a complete description of
the Commands, Queries, Responses and Reports on this interface, please
refer to the section D which follows.

2139 High Tech Road • State College, PA 16803 • USA
26
C. Half duplex and polled (multi-drop) operations
The RS-485 interface is provided to permit a network connection from
one computer to multiple instruments. A three-wire (with feed-through)
screw terminal connector is furnished on the rear panel of the TE-3000
which allows the use of any three conductor cable (two wire shielded,
preferred) to be connected into and out of the instrument. The computer
must have an RS-232 to RS-485 adaptor plugged into the computer serial
port.
Network capability
The network is capable of supporting up to 16 instruments at distances of
up to 4000 feet. If the network is configured for more than three occupants and/or if the network spans a long distance (>100 feet) then it may
be required that termination resistors be added to the first and last occupant on the network. Contact CANNON® Instrument Company for
further assistance about the configuration of your particular network
needs.
For a complete description of the Commands, Queries, Responses, and
Reports on this interface, please refer to section D which follows.
D. Commands, queries, responses and reports
The protocol on the serial interfaces includes commands and queries
which are sent by a master controlling computer, and responses which are
sent by the TE-3000 in reply to every command or query it receives. The
TE-3000 may also issue timed interval reports automatically if it is
configured to operate in the point-to-point mode. If the TE-3000 is
configured to operate in the multi-drop mode, reports will only be issued
in response to a specific query.
Protocol
All Commands and Queries sent to the TE-3000, regardless of which
interface, must be preceded by a / and a #. The # is the selected address
(rear address switch) of the TE-3000 and must be 0-9 or A-F while the /
is a simple slash character denoting the beginning of an addressed
command or query.

CHAPTER
MAINTENANCE

66
The TE-3000 was designed for minimal care and maximum reliability.
By following a few basic rules of preventative maintenance, the TE-3000
should provide years of trouble free operation.
Additionally, the TE-3000 provides an automatic built-in self test which
examines the operation and performance of the instrument. These diagnostic routines assist the user by presenting the results of all tests and a
determination of what is wrong if any test fails. This gives the user a high
level of confidence that the instrument is functioning properly or if not,
exactly where the problem is located.
A. Preventative (scheduled) maintenance
The TE-3000 requires a minimum amount of maintenance at intervals
that are entirely dependent upon the environment and the degree of
usage. In the typical situation of an average modern laboratory performing a dozen tests daily, the following items should be performed every six
months. If the bath is located in a dirty environment and/or is heavily
used, the preventative maintenance listed below should be scheduled on a
monthly basis.
31
Cleaning of painted surfaces and front panel
Cleaning the fans and heat sinks
Cleaning fans
The finish of the TE-3000 is a baked-on epoxy enamel in colors of
almond and black. This paint is virtually immune to most solvents,
however, if acetone is rubbed on the painted surfaces, the paint will be
removed. A good quality household cleaner may be used on all painted
surfaces and the front panel. Do not spray the cleaning fluid directly on
any surface, especially the area where the fans and heat sinks are located.
The liquid will harden dust particles and cause an accumulation of dust to
be imbedded into the heat sinks and make removal very difficult. Instead,
a soft cloth should be sprayed with the cleaning solution and the cloth
should be used to transfer the solution to the surface of the instrument.
Dust and dirt will accumulate with time in the small gaps of the air heat
sinks and around the blades of the fans. These deposits will affect the
cooling effectiveness of the thermoelectric cells and will ultimately affect
the ability of the bath to go to cold temperatures. The easiest and most
effective way to clean these heat sinks and fans is by using a compressed
air source and blowing the dust away. This should be accomplished by
moving the upper Bath Vessel Assembly outside or away from any clean
environment, apply the blasts of clean air through the fans on the sides

and the rear, and alternately apply blasts of air directly into the heat
sinks. This can be accomplished without removal of any panels surrounding this upper Bath Vessel Housing.
Cleaning heat sinks
Removing side panels
Compressed air cleaning
If the bath is operating in a high humidity environment, the dirt may
become very hard and encrusted on the fins of the heat sinks. When this
condition is noticed while attempting to blow out the dust, remove the
left and right side panels to gain access to the heat sinks.
Each side panel is attached with four screws and should be removed by
moving the detached side panel outward for a small distance and then
upward to avoid striking the fluorescent lamp.
Using a soft, long bristled brush (available in automotive departments for
cleaning wire wheels) loosen the encrusted dust and then blow it away
with the compressed air source. Care should be taken to not bend or
crush the fins of the heat sinks.
Assemble the side panels back onto the Bath Vessel Housing by reversing
the removal procedure.
If a central or self-contained air compressor line with a blow gun is not
available, compressed air (aerosol) cans may be obtained from most
computer supply dealers. These cans may be used in conjunction with a
long nozzle to facilitate directing most of the air into a confined area.
Cleaning the bath window
The viewing window on the TE-3000 is constructed with four panes of low
emissivity glass with all panes tempered for safety. The space between these
panes are filled with a gas and sealed to provide a frost-free viewing window. The outside (front) surface of this window may become smudged and
dirty and should be cleaned with common household window cleaner. Apply
window cleaner to a soft cloth and wipe on the front window of bath.
NOTE
Do not spray cleaner directly
on front face of glass.
Draining the bath liquid
Remove all power from the TE3000 and remove all instruments from the bath prior to the
draining operation.
The bath liquid in the TE-3000
must be removed by siphoning
action (see Figure 9). A general
purpose siphon is available
wherever kerosene heaters are

Figure 9: Siphoning bath liquid
sold. This simple plastic device has an integral squeeze pump to start the
siphoning with a long, straight input hose and a flexible output hose.
A more effective method is a vacuum system with a container trap for
containment of the bath fluid. The continuous vacuum in such a system
provides an easy means to remove any solid dirt particles and completely
empty the bath.
Using a siphon or vacuum hose placed into one of the two instrument
holes at the top, transfer all of the bath liquid into another container.
Briefly turn on bath power and energize the fluid return pump by depressing the push button on the rear of the Control Housing.
33
CAUTION
Do NOT leave TE-3000 power on without liquid in the bath!
Once it is apparent that most of the liquid has been removed from the
overflow jar and hoses and transferred back into the bath, remove the
power from the TE-3000 again and continue to siphon or vacuum the
bath liquid.
After the bath has been drained as much as possible, remove the overflow
jar and associated hoses from the rear of the Bath Vessel Housing and
empty their contents into this container.
Cleaning the inside of the bath vessel
Depending on the grade of alcohol being used as a bath liquid, the
frequency of replacing the bath liquid may vary greatly. The contaminants contained in solution with the alcohol will remain as sediment in
the bath after the alcohol evaporates. If the bath temperature is always
maintained at a cold temperature and the holes at the top are always
covered, the rate of evaporation of the alcohol will be at a minimum.
Conversely, if the bath is maintained in the power off condition and the
top holes are uncovered, the room temperature alcohol will evaporate
quickly.

After all of the bath liquid has been removed and the bath vessel is at
room temperature, the cleaning procedure can begin. The actual process
of cleaning is difficult at best without the proper cleaning implements. A
long handled brush, such as one available from Thomas Scientific (cat.
No. 1929-M80), permits scrubbing the baffle, side walls, and the inside
of the bath window. Again, a good quality household cleaning agent may
be used. Spray the liquid cleaning agent through one of the top holes in
the bath vessel and use the brush to scrub off the residue on the baffle,
side walls, and bath window. Water should be used to rinse the vessel and
a siphon or vacuum system for removing the remaining mixture from the
vessel. Ensure that the vessel is clean and dry before refilling with clean
alcohol. Use lint-free towels to wipe the vessel dry if a vacuum system is
not available.
