Caution: The calculated pump flow rate is the minimum required to obtain the
desired control band, however, if the flow rate increases over the recommended rate
of 500 mL/min (approx. 0.13 gal/min) the rate of cooling will decrease. This may be
compensated for by re-evaluating the system criteria: length / desired control band
or to double up on the cooling plate/coil.
Consult factory with any further installation questions.

Control Module Installation
Once the enclosure is mounted, the output pumps may be located at any distance
from the controller. The sensor may be placed up to 80 feet from the controller.
Shielded cable is preferable. Always route AC voltage wiring in conduit that is
separated a minimum of 6 inches away from low voltage DC signal lines (such as
the sensor signal).
