and diagrams throughout this Guide.

Using the checklist

This chapter uses a checklist format to detail the required utilities,

accessories, clearances, personnel and training issues to be considered

prior to, and during installation of the CAV-2100 instrument(s) in your

facility. Please review the checklist carefully and address any outstanding

issues to facilitate a successful installation.

Required utilities for CAV installation

The following utilities must be supplied by the CAV user:

1.___Electrical power

MAINS~

The CAV is designed to operate from several world AC power sources.

However, voltage and frequency requirements are specified by the CAV

user when the CAV is ordered. The exact power requirements for the

CAV are indicated on the label on the rear panel of the Bath Unit. Con-

sult CANNON

with any questions regarding power requirements.

CAUTION

Proper electrical grounding is extremely important. The CAV is supplied

with a power cord with an integral safety ground which must be con-

nected to an AC mains receptacle with an earth ground.

2.___Compressed air/nitrogen and vacuum

The CAV requires a source of compressed air or nitrogen. The com-

pressed air must be free of water, oil and particulates. Consumption of

the compressed gas is dependent upon the operations being performed.

2139 High Tech Road • State College, PA 16803 • USA

The compressor must be capable of producing a constant air flow of 3

cfm (5 m

/hr) at 40 psi (275 kPa) minimum. Line pressure should be set

at 75-100 psi (517-690 kPa). If the CSU-200 Service Unit is not being

used, vacuum must be supplied by the user to the rear panel VACUUM

connection on the Bath Unit. Vacuum should be approximately -8 in Hg

to -10 in Hg, and should be suitable for the solvent/samples being run.

3.___Sample/waste disposal

The customer must provide for the containment and disposal of all used

solvents and waste oils. Collection, storage, and disposal of all waste

from the CAV is the responsibility of the customer, and must be done in

accordance with all local safety and environmental regulations.

4.___Cooling water

Instruments maintaining bath temperatures lower than 40°C require a

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”).

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

/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.

Power connections

MAINS

The Service Unit Mains power connection is located in the upper left

corner of the CSU rear panel. Voltage/frequency requirements are clearly

indicated on the rear panel label.

CAUTION

Do not turn on the Service Unit power switch until all connections have

been completed correctly and the SDU has been properly grounded.
