CHAPTER

SETUP
The instructions in this chapter are for setting up a single CMRV-4500
with the Air/Water Heat Exchanger. For additional information on multi-
unit configurations, see APPENDIX D.
CAUTION Do not apply power to the CMRV-4500 or Heat Exchanger until all
connections are secure.
Physical placement
CAUTION Some CMRV components, including the Air/Water Heat Exchanger, are
quite heavy. To avoid injury, obtain necessary assistance when lifting
and moving these components.
Control unit placement Place the CMRV-4500 on a stable laboratory bench or table top within 10
mm of the front edge. This will allow the weight suspended from the
pulley-wheel assembly to clear the edge of the table during viscosity and
yield stress tests. Allow 30.5 cm (12") of clearance to the back and sides
of the unit.
A/W Heat Exchanger Place the Air/Water Heat Exchanger below the table top on which the
CMRV-4500 is placed. The unit may be located within the parameters
permitted by the length of the hoses and cables shipped with the unit.
CAUTION Do not obstruct the front or rear cooling vents on the Air/Water Heat
Exchanger.
Thermometer placement When in use, the large thermometer (-46°C to +30°C) is placed in the
thermometer well on the left side of the CMRV-4500 unit (seen from the
front).
When in use, the small thermometer (0°C to 105°C) is placed in the ther-
mometer well on the right side of the CMRV-4500 unit (as seen from the
front).
NOTE If the mercury column in a thermometer has separated during shipment,
read the instructions included in APPENDIX C. These instructions offer
several methods for joining separated mercury columns.
