Requirements
Ensure that all shipping plugs are removed before installation.
Never connect the process fluid lines to your facility water supply or
any pressurized liquid source.

To prevent damage to the chiller's plate exchanger, centrifugal pumps
require a 4.0 gpm (15.1 lpm) minimum flow rate.

P 1 and P 2 pumps are capable of producing 185 psig. Ensure your
plumbing is rated to withstand this pressure at your operating
temperature. An external pressure relief valve is available, see Section 5.

Note Ensure your plumbing installation develops a back pressure to the
ThermoFlex greater than 3 PSIG. Lower pressure will shut down the chiller.

The process fluid connections are located on the rear of the chiller and are
labeled (PRoCESS ouTLET) and ( PRoCeSS InLeT ).
