SDU-200 Solvent Dispensing System
The CAV is equipped with a solvent system used to wash the viscometer
tubes 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. Appropriate solvent containers may be
acquired from many suppliers, including JustRite
® and Nalgene ® (see

CSU-200 Service Unit
The Service Unit (CSU-200) contains control electronics, vacuum pump
and pressure regulators for air, solvent and vacuum. Each CSU-200 is
capable of providing regulated gas/vacuum for up to four Bath Units.
NOTE If the user has in-house regulation of gas and vacuum, these connec-
tions can be made directly to the Bath Unit. See chapter 5 for required
pressure/vacuum settings.
CSU-200 connections
For information regarding CSU-200 connections, refer to the CAV
Installation & Setup Guide.
NOTE A compressed air source is required for connection to the Service Unit.
Emptying the waste can
CAUTION Check the volume of the waste can at the beginning of every work shift,
to avoid solvent spillage or overflow.
The waste can collects solvent and sample residue drained from the
viscometer tubes during the cleaning process. CANNON
® Instrument
Company does not supply a waste can. The CAV should be connected to
a suitable safe container, approved by local safety personnel. The drain
system operates on a gravity flow system.
CAUTION
The drain line must be kept short and neat (no loops or knots) or an air
lock could result.
