CAUTION!

Exposure to acetone liquid or acetone vapor may damage the cover.

2. Turn on the CMRV-4500 (the green power indicator on the switch

will light and the left panel lights will flash once).

NOTE

The CMRV cleaning procedure may be initiated from a "cold" CMRV;
however, a calibration or profile should not be initiated until the instru-
ment has completed a warmup period of approximately 45 minutes. If the
warm-up period is less than 45 minutes, the instrument may not control
temperature within acceptable tolerance parameters.

3. Assemble the necessary cleaning supplies:

oil solvent
acetone (optional during low humidity)
suitable solvent-resistant container for placing/cleaning rotors
vacuum w/trap for solvent and oil
flexible tube, about 150 mm long and 3-5 mm in diameter, connected
to the vacuum trap

two plastic squeeze bottles, each with an extension long enough to be
able to direct oil solvent and acetone directly into the cup of the
viscometer cells

4. Start the VISCPRO

cleaning. Hanging a paper clip on each loop reduces the chance of curling.
