Process Fluid Connections
The Chiller has two internally threaded fittings on the rear of the instrument housing for the process water
connections. Two sets of adapters are supplied with the unit for connecting these fittings to the process piping.
The direction of the flow through the system can be controlled by the way the connections are made. Fluid is
drawn into the Chiller through the “Inlet” connection; fluid is pumped out of the Chiller through the “Outlet”
connection.
NOTE:
When Chillers with the standard magnetic drive centrifugal pump are connected to an external
apparatus with a built-in shutoff, an external bypass loop assembly (Part No. 510-147) may be needed if
operating below 20°C (68°F). This bypass assembly continues flow circulation to and from the pump even
though the main flow to the external apparatus has been blocked.
Facility Water Connections
WARNING:
On units requiring facility water, those connections must be made by a licensed plumber.
CAUTION:
The incoming cooling water pressure should be 20 psi / 1.4 bar minimum and 150 psi / 10.3 bar
maximum.
Water-cooled Chillers have two internally threaded fittings on the rear of the instrument housing for the facility
water connections. The cooling water supply should be connected to the facility water inlet on the Chiller. The
facility water outlet on the Chiller should be connected to the appropriate return or drain, as required.
The cooling water supply may be from city tap water or a cooling tower. The incoming water pressure should be
between 20 and 150 psi / 1.4 and 10.3 bar.
Reservoir Drain
A connection is provided for the reservoir’s gravity drain.
Reservoir Vent
A reservoir vent assembly is provided with Chillers equipped with the heater option to relieve pressure within the
reservoir as coolant heats and expands. A connection is provided on the rear of the Chiller for the vent assembly.
