source of cooling water. Cooling water connections are located at the rear
of the CAV unit. The cooling water should be maintained at 15-20°C
below the bath temperature setting.
NOTE
Temperature baths operating at 40°C may require circulating cooling
water, particularly if the room temperature of the laboratory exceeds
24°C (75°F).
5.___Ventilation
All models of the CAV are provided with a 4” (10.16 cm) diameter
ventilation shroud in the rear panel of the unit. A ventilation system
having a continuous airflow adequate to ensure removal of solvent fumes
and vapors should be connected to the CAV. CANNON
®
Instrument
Company does not supply ventilation fans, hoods, or systems.
CAUTION
The CAV must be operated with ventilation precautions appropriate for
your facility and the sample materials and solvents being used.
CANNON
®
recommends that the CAV be connected to an external
ventilation system. The 4” (10.16 cm) diameter opening on the back
panel of the CAV will accommodate a standard 4" dryer hose. If any
solvent vapors are detected around the CAV, verify the operation of the
exhaust ventilation system.
6.___Laboratory environment
It is important that the CAV be kept in a suitable laboratory environment.
The room temperature of the laboratory must be maintained between
15°C and 27°C (60-80°F). The laboratory must be free of dust and dirt,
which could possibly taint the samples. The laboratory must be equipped

Initial pre-fill procedure
1. Make certain that the drain valve at the bottom of the bath is closed
and that the plug is in place (see photo). If it is not, you will need to
remove the front window panel to access the drain valve. Loosen and
remove the screws securing the top rear cover to the CAV Bath Unit.
Then remove the cover.
2. (CAV-2100 instrument only) If the bath is empty, remove the plug/
cap from the Swagelok
®
fitting at the front of the top bath flange.
This fitting is for the
thermometer holder.
Removing it will prevent
air lock during the initial
fill procedure.
3. Obtain the (supplied)
funnel and locate the fill
tube (CAV-2100, see
photo) or fill hole (CAV-
2200, see photo) at the top
of the temperature bath.
For the CAV-2100, open
the flip-cap on the expan-
sion vessel. For the CAV-
2200, loosen the knurled
thmbscrew securing the
aluminum hole cover to the
top bath flange and slide
the cover free of the
opening to insert the
funnel.
NOTE
If you have installed a cooling device in place of the fill tube, you may fill
the CAV-2100 bath through the expansion vessel (see photo). The CAV-
2200 does not have an expansion vessel.
4. Select the desired bath fluid grade for your operating temperature(s).
5. Using the funnel, slowly introduce the appropriate grade of silicone
bath fluid. For CAV-2200 baths, continue adding fluid until the cold-
fill line is reached. For CAV-2100 instruments, add fluid until the
liquid meniscus is 1/4” (3.8 mm) below the top bath flange at the top
of the bath.
Reduce the flow rate as the meniscus approaches the top
of the bath to avoid overfilling!
6. (CAV-2200 only) Turn on the CAV instrument to engage the pump
system. Monitor the liquid level as fluid enters the pump system and
add additional fluid as necessary to refill to the cold fill line.
7. Remove the funnel. Return the flip cap or hole cover to its original
position.
8. (CAV-2100 only) Insert the reference thermometer into the thermom-
eter holder and slide the thermometer holder into the fitting at the

fitting nut. Carefully slide these O-rings down the thermometer
holder and into the fitting-top. Then place the fitting nut over the O-
rings. Tighten the fitting finger-tight, then secure with a wrench.
CAUTION
Do not overtighten the Swagelok
®
fitting or you may damage the O-rings.
NOTE For information on draining the bath, consult the Instruction & Operation
Manual.
9. After installing the thermometer and holder, check to make certain
that the other top bath flange fittings are sealed tightly.
CAUTION
During the initial CAV-
2100 heating cycle,
monitor the liquid level as
it rises into the expansion
vessel. Check the bath
fittings for leaks to com-
plete the fill procedure.
Tighten fittings if neces-
sary.
NOTES
The expansion vessel has
been designed to hold
excess liquid when the
CAV-2100 is operating at
high bath temperatures
(see photo, right). As
indicated previously, the
expansion vessel will be
empty at ambient tem-
perature. Do not fill the
bath above the level
indicated in step #5 when
the bath temperature is at
or near ambient.
CAUTION
When filling the temperature bath, do not fill above the top bath flange
(CAV-2100) or the cold-fill line (CAV-2200).
Coolant connections
The CAV offers two different cooling options when operating the instru-
ment at temperatures lower than 40°C—a heat exchanger tube or the
CBC-2K CANNON
®
Bath Cooler (older models provided a cooling
coil). Both devices are installed via the 20-mm Swagelok
®
fitting in the
top bath flange. When cooling devices are in use, the fitting secures a
convenient fill tube for bath fluid. Remove the fill tube before installing
your cooling device!

tion in the aperture in the top bath flange of the Bath Unit. It is secured
with two O-rings. Slide the nut and two O-rings onto the CBC-2K tube.
Then slide the CBC-2K into the bath until the bottom of the finger is
approximately 2” from the bottom of the bath (or until the bend in the
tube prevents further insertion). Then tighten the cap nut finger-tight and
secure with an additional 1/4 turn.
CAUTION
The CBC-2K is designed for cooling between 20°C and 100°C. Do not
use the CBC-2K with the CAV high-temperature bath option.
Sample trays/drains
Both heated and unheated sample trays will slide into place along the
grooved track in the sample table. The plated steel vial adaptors should
be placed in the receptacles in the tray. Glass sample vials slide into the
adaptors. Place the sample tray in the track and slide the tray forward
until the detente mechanism engages. At position 1 (first sample directly
underneath the viscometer tube), a heated sample tray should snap into
position against the detent mechanism when the front of the tray extends
approximately 2 centimeters (3/4”) over the edge of the sample table. The
forward edge of an unheated tray will be indented approximately 2.2
centimeters (7/8”).

Electrical connections
For (optional)
heated sample
trays, connect
the keyed three-
pin cable from
the sample tray
to the interior
wall connector
above the
sample table
(see photo, next
page), orienting
the cable in a
“U” configura-
tion aside the
sample tray.
Turn the knurled
ring clockwise to engage and secure the connector.
Tray/drain heat operations
To provide power to the heated sample trays and/or heated drain lines
which may be installed on your CAV unit, you will use the heater ON/
OFF switches on the left side of the front panel (see diagram, left). These
two switches provide power to left- and right-hand heating elements. To
adjust temperature, use the Adjust knobs on the upper front panel of the
Bath Unit. Turn the knobs clockwise to increase temperature and counter-
clockwise to lower it. The knobs regulate the duty cycle of the heaters for
the sample trays and the drain lines.
The low-temperature sample heaters will maintain temperature stability
as high as 80°C. The high-temperature sample heaters will maintain
temperature stability as high as 100°C.
NOTE
During normal operation, the green lamp on the heated sample tray
holder will illuminate and/or blink in tandem with the red LED on the front
panel ON/OFF switch. If the green lamp is NOT flashing, check cable
connections and sample block temperature (block may be overheated
and may need to cool down).
Using a temperature probe
A recessed thermometer well (3.63 mm; 0.143” ID) at the front of the
sample tray permits insertion of a temperature probe to monitor tray
temperature for heated sample trays.
Splash guards
To reduce the risk of contaminating samples, and to protect the viscom-
eter tube from damage, the exposed viscometer tube tips should be
shielded with splash guards (provided). Use the captive thumb screw on
the top of the splash guard to secure it to the underside of the Bath Unit
frame in front of the viscometer tube tip. The felt pad should face the
tube tip (see photo, previous page).

Ventilation exhaust shroud
The CAV requires installation of the exhaust shroud on the rear panel of
the unit. The shroud must be connected to a customer-supplied exhaust
fan/ventilation system. The air flow rate and design of the exhaust fan
must be suitable to handle the vapors from the customer supplied solvent
and samples. A 4" (10 cm) solvent-safe ventilation hose should be
connected to the exhaust shroud on each Bath Unit.
Service Unit connections
The CSU-200 Service Unit houses an internal vacuum pump and regula-
tor, as well as two air pressure regulators. Pressure/vacuum settings are
monitored via the front panel dials. Up to four CAV instruments can be
connected to a single Service Unit.
CSU-200 connections
To complete CSU-200 connections, refer to interconnect diagrams,
including the diagram on the last page of this manual, and these instruc-
tions.
CAUTION
IMPORTANT SAFETY NOTE: The SDU-200 Solvent Dispensing Unit
must be properly grounded prior to use. See below for details on proper
installation and grounding.
Air connections
Using 1/4” OD Poly-Flo
®
tubing, complete an attachment from the user
air source (maximum pressure—100 psi (690 kPa); minimum 75 psi
(517 kPa)) to the MAIN INPUT connector on the rear panel of the
Service Unit. The compressor must be capable of producing a constant
flow of 3 cfm (5 m
3
/hr) at 40 psi (275 kPa). A water trap and air filter

must be installed by the customer on the laboratory air supply line. A 60-
micron filter is factory-installed inside the CSU-200 on the main air inlet
(MAIN INPUT).
Tighten the Poly-Flo
®
fittings finger-tight and secure with an additional
full turn using an adjustable or open-end wrench.
Locate the AIR and NVIS ports on the lower rear panel of the Bath Unit.
Using two short pieces of the 1/4” OD tubing, connect these ports to a
Polyflo “T” fitting. Connect the third leg of the “T” to the CSU-200 port
labeled TO CAV.
Connect a short length of 1/4” OD tubing to the TO CAV connector on
the Service Unit. “T” the open end of the tube; then attach both legs to
the AIR and NSOLV connectors on the lower rear panel of the Bath Unit.
Optional Nitrogen connection
The CSU-200 must be internally replumbed prior to using the nitrogen
port. Consult CANNON for details of replumbing.
CSU/SDU connection
Connect the 1/4” OD tubing from the SOLVENT FLOW CONTROL
NSOLV IN connection on the Solvent Dispensing Unit to the NSOLV
OUT connector on the Service Unit. Tighten the Poly-Flo
®
fittings
finger-tight and secure with an additional full turn using an adjustable or
open end wrench.
Vacuum connections
Connect the CANNON
®
-supplied vacuum trap to the VACUUM TO
CAV connector on the CSU-200. Then connect a length of 1/4” OD Poly-
Flo
®
tubing from the other connector on the vacuum trap to the
VACUUM connector on the CAV Bath Unit upper rear panel.
Tighten the Poly-Flo
®
fittings finger-tight and secure by tightening an
additional full turn with an adjustable or open end wrench.
Attach the vacuum pump muffler to the EXHAUST connector on the
CSU-200.
