Initial pre-fill procedure 1. Make certain that the drain valve at the bottom of the bath is closedand that the plug is in place (see photo). If it is not, you will need toremove the front window panel to access the drain valve. Loosen andremove 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 thethermometer holder.Removing it will preventair lock during the initialfill procedure.

3. Obtain the (supplied)funnel and locate the filltube (CAV-2100, seephoto) or fill hole (CAV-2200, see photo) at the topof the temperature bath.For the CAV-2100, openthe flip-cap on the expan-sion vessel. For the CAV-2200, loosen the knurledthmbscrew securing thealuminum hole cover to thetop bath flange and slidethe cover free of theopening to insert thefunnel.

NOTE If you have installed a cooling device in place of the fill tube, you may fillthe 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 siliconebath fluid. For CAV-2200 baths, continue adding fluid until the cold-fill line is reached. For CAV-2100 instruments, add fluid until theliquid meniscus is 1/4” (3.8 mm) below the top bath flange at the topof the bath. Reduce the flow rate as the meniscus approaches the topof the bath to avoid overfilling!

6. (CAV-2200 only) Turn on the CAV instrument to engage the pumpsystem. Monitor the liquid level as fluid enters the pump system andadd additional fluid as necessary to refill to the cold fill line.

7. Remove the funnel. Return the flip cap or hole cover to its originalposition.

8. (CAV-2100 only) Insert the reference thermometer into the thermom-eter holder and slide the thermometer holder into the fitting at the

front of the top bath flange. The holder has two O-rings under thefitting nut. Carefully slide these O-rings down the thermometerholder 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 & OperationManual.

9. After installing the thermometer and holder, check to make certainthat the other top bath flange fittings are sealed tightly.

CAUTION During the initial CAV-2100 heating cycle,monitor the liquid level asit rises into the expansionvessel. Check the bathfittings for leaks to com-plete the fill procedure.Tighten fittings if neces-sary.

NOTES The expansion vessel hasbeen designed to holdexcess liquid when theCAV-2100 is operating athigh bath temperatures(see photo, right). Asindicated previously, theexpansion vessel will beempty at ambient tem-perature. Do not fill thebath above the levelindicated in step #5 whenthe bath temperature is ator 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 connectionsThe CAV offers two different cooling options when operating the instru-ment at temperatures lower than 40°C—a heat exchanger tube or theCBC-2K CANNON® Bath Cooler (older models provided a coolingcoil). Both devices are installed via the 20-mm Swagelok® fitting in thetop bath flange. When cooling devices are in use, the fitting secures aconvenient fill tube for bath fluid. Remove the fill tube before installingyour cooling device!

CBC-2K connections The CBC-2K CANNON® Bath Cooler is installed in the 20-mm connec-tion in the aperture in the top bath flange of the Bath Unit. It is securedwith 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 isapproximately 2” from the bottom of the bath (or until the bend in thetube prevents further insertion). Then tighten the cap nut finger-tight andsecure with an additional 1/4 turn.

CAUTION The CBC-2K is designed for cooling between 20°C and 100°C. Do notuse the CBC-2K with the CAV high-temperature bath option.

Sample trays/drainsBoth heated and unheated sample trays will slide into place along thegrooved track in the sample table. The plated steel vial adaptors shouldbe placed in the receptacles in the tray. Glass sample vials slide into theadaptors. Place the sample tray in the track and slide the tray forwarduntil the detente mechanism engages. At position 1 (first sample directlyunderneath the viscometer tube), a heated sample tray should snap intoposition against the detent mechanism when the front of the tray extendsapproximately 2 centimeters (3/4”) over the edge of the sample table. Theforward edge of an unheated tray will be indented approximately 2.2centimeters (7/8”).

14



Electrical connections For (optional)heated sampletrays, connectthe keyed three-pin cable fromthe sample trayto the interiorwall connectorabove thesample table(see photo, nextpage), orientingthe cable in a“U” configura-tion aside thesample tray.Turn the knurledring clockwise to engage and secure the connector.

Tray/drain heat operations To provide power to the heated sample trays and/or heated drain lineswhich 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). Thesetwo switches provide power to left- and right-hand heating elements. Toadjust temperature, use the Adjust knobs on the upper front panel of theBath Unit. Turn the knobs clockwise to increase temperature and counter-clockwise to lower it. The knobs regulate the duty cycle of the heaters forthe sample trays and the drain lines.

The low-temperature sample heaters will maintain temperature stabilityas high as 80°C. The high-temperature sample heaters will maintaintemperature stability as high as 100°C.

NOTE During normal operation, the green lamp on the heated sample trayholder will illuminate and/or blink in tandem with the red LED on the frontpanel ON/OFF switch. If the green lamp is NOT flashing, check cableconnections and sample block temperature (block may be overheatedand may need to cool down).

Using a temperature probe A recessed thermometer well (3.63 mm; 0.143” ID) at the front of thesample tray permits insertion of a temperature probe to monitor traytemperature for heated sample trays.

Splash guardsTo reduce the risk of contaminating samples, and to protect the viscom-eter tube from damage, the exposed viscometer tube tips should beshielded with splash guards (provided). Use the captive thumb screw onthe top of the splash guard to secure it to the underside of the Bath Unitframe in front of the viscometer tube tip. The felt pad should face thetube tip (see photo, previous page).

The CAV is equipped with a solvent system used to wash the viscometertubes after each sample test. The system consists of the Solvent Dispens-ing Unit (SDU), the internal and external drain lines, and the user-supplied solvent and waste cans. The SDU will interface with the CAN-NON Service Unit (CSU) and the CAV instrument. Use the instructionsin the following section to complete solvent connections.

CSU SDU

Solvent connections (single and dual solvent systems)Refer to the included interconnect diagram for information on single ordual solvent connections. Solvent connections are made at the connectorson the rearpanel of theSolventDispensingUnit (SDU)and ServiceUnit (CSU)using fittingsappropriatefor the 1/4”-OD Poly-Flo® (air/nitrogen/vacuum) and1/4”-ODFEP (solvent) tubing.

SOLVENT port The SDU SOLVENT IN port supplies replacement solvent from theuser’s supplied solvent container to the Solvent Dispensing Unit. Insertone end of the 1/4”-OD Poly-Flo® solvent tube into the user’s washing

solvent vessel. The other end of the tube should be attached to the SDUSOLVENT IN ‘A’ port. If using an optional drying solvent, insert oneend of the 1/4”-OD Poly-Flo® solvent tube into the user’s washingsolvent vessel. The other end of the tube should be attached to the SDUSOLVENT IN ‘B’ port.

SOLVENT OUT port(s) The SOLVENT OUT ports dispense solvent from the SDU to the CAV-2100 head unit upper rear panel connections. Use 1/4”-OD FED tubing tocomplete these connection to the appropriate solvent intake on the upperrear panel of the CAV Bath Unit (see APPENDIX photography andassembly diagram).

NOTES Single-solvent systems should be plumbed to the CAV bath unit solventport A. The Port B Bath Unit connection must be capped at each BathUnit. For single-solvent systems, this is done at the factory. Use only1/4”-OD FED tubing for solvent connections.

Waste can connectionsThe customer-supplied waste can collects solvent and sample residuedrained from the viscometer tubes during the cleaning process. CAN-NON® Instrument Company does not supply a waste can. Using theprovided 1/2”-OD Nylo-Seal® tubing, connect the CAV drain ports foreach viscometer to a suitable safe container, conforming to local safetyregulations. The drain system operates by gravity flow.

CAUTION The drain line must be kept short and neat (no loops or knots) or an airlock could result.

Procedure 1. Attach the “T” connector to the Left and Right copper Drain portson the lower rear panel of each Bath Unit. Tighten the Nylo-Seal®

fittings finger tight and secure by turning an additional full turn withan adjustable wrench.

2. Connect the waste can to the connector with an appropriate length of½” Nylon® tubing (see previous CAUTION statement).

NOTE Make certain that the connection is oriented in a manner which permitsgravity flow of waste from all outlets directly to the waste can.

3. Ventilate the waste can to the user’s ventilation system.

WARNING Do not store the waste can in an area in which temperatures exceed40°C. Do not store near open flames. Do not store in an enclosed area,where fumes and vapors may build up.

Drip pan drain A separate bulkhead connector is available at the rear of the CAV BathUnit for drainage of the drip pan. Attach a length of drain hose to theconnector and route the hose to a safe solvent/sample container (con-forming to local safety regulations), making certain that gravity flow isunimpeded (no loops or knots).

20



Emptying the waste canCheck the volume of the waste can at the beginning of every work shift,to avoid solvent/sample spillage or overflow.

Procedure 1. Disconnect the waste can from the drain tube(s).

CAUTION Be careful when handling the drain tube, to avoid spilling or splashingwaste solvent collected in the tube. Take safety precautions whenworking with the solvent lines. This includes using safety glasses andprotective gloves.

2. Pour the collected solvent out of the waste can into a proper wastestorage container.

3. Replace the drain tube(s) in the waste can.

WARNING Waste solvents can present possible environmental and health hazards.Dispose of all waste solvents according to environmental safety regula-tions.

Checking the solvent level Check the solvent liquid level frequently. Refill the solvent container asnecessary.

Adjusting pneumatic controls

Control pneumatics are adjusted from the CAV pneumatic drawer at thebottom of the Bath Unit. A key is required for access to pneumaticcontrols through the hinged front panel. These controls are normally setduring installation and seldom require adjustment.

Regulation of tube drying The NVIS regulator (NVIS gauge) regulates the compressed air/nitrogensupply used to dry the viscometer tubes. The pressure should be setbetween 20-30 psi. Pull the control knob out, then rotate the knob toadjust the pressure setting. When done, push the knob in to lock at thedesired setting.

Other viscometer controls Pneumatics for both viscometer tubes have four corresponding controls(ADVANCE, AIR RETURN, LOAD and SHIFT) located on the innerpneumatic drawer panel of the CAV. These controls adjust the air pres-sure used to regulate the speed at which respective mechanisms move.

21

The speed of these mechanisms should be set to allow them to functionsmoothly and efficiently without spilling or splashing the sample. Turnthe control knob clockwise to increase the pressure. Turn the controlknob counterclockwise to decrease the pressure.

Adjust the tray/table pneumatic mechanisms in the following manner:

Set the AIR RETURN regulators to the minimum setting to allow forreturn/retraction of the LOAD and ADVANCE cylinders. Set the corre-sponding LOAD and ADVANCE regulators slightly higher than the AIRRETURN regulators to ensure that the cylinders can extend fully.

After adjustments are complete, close the hinged access panel.

NOTE Closing the access panel will also lock it.
