Exchanger when the unit commences operation. You will be able to
observe the liquid circulating inside the reservoir from the opening at the
top of the Exchanger during normal operation. If air bubbles are consis-
tently visible in the coolant lines, add additional mixture until the Ex-
changer is full.
CAUTION The water-antifreeze mix should be replaced annually for reliable perfor-
mance and to prevent corrosion of internal components (see Flushing
and draining the Air/Water Heat Exchanger, this chapter).
Electrical /serial connections
A/W Heat Exchanger Plug the male end of the DC power cable into the DC POWER OUT
fitting on the rear panel of the Air/Water Heat Exchanger and turn the
locking clip clockwise to secure the connection. Attach the other end of
the cable to the receptacle labelled
DC POWER at the back of the
CMRV-4500 unit (see figure, previous page). This connection provides
power to the thermoelectric cooling modules.
Insert the power cable for the Air/Water Heat Exchanger into the recep-
tacle on the Exchanger rear panel. Secure the power cable in place by
tightening the Phillips screw on the cable clamp.
Make sure the Air/Water Heat Exchanger power switch is in the OFF
position; then insert the power line cord from the Exchanger into an
appropriate power source for your unit.
Before providing mains power to the unit, check the label on the rear
panel of the Exchanger to verify that the electrical specifications for the
unit match those of the power supply.

Attach the M-F three-prong connector cable from the Exchanger PUMP
outlet to the PUMP receptacle on the CMRV-4500 controller (see figures on
pages 12-13). This power connection permits CMRV-4500 control of pump
operation.
Thermistor Insert the Lemo ® plug from the temperature probe into the jack marked
TEMP PROBE on rear of the CMRV controller (see Figure 11). Insert
the probe tip as far as it will go into the hole marked THERMISTOR on
the rear of the CMRV-4500 chassis.
