All process piping materials (such as hoses, rigid piping, valves or filters) used
with process water piping circuitry must be rated for 100°F {37.8°C} minimum
temperature and 150 PSI {10.3 bar} minimum pressure.
All such materials must have the equivalent or larger diameter of the particular
process connection that the length of process water piping is connected to.
Process water piping circuitry should be designed to avoid an excessive use of
elbows and/or lengths of pipe or hose. If hose is the material of choice, avoid
tight twists or curls and excessive lengths.
Valves and filters may be installed in the process water piping circuitry to
facilitate service and maintenance provided that these devices maintain the full
inside diameter of the process connection. If installed, all devices must be open
and clean during unit operation.
Warm coolant from process equipment enters the chiller at the “From Process”
inlet and chilled coolant returns to the process equipment through the “To
Process” outlet.
To connect process plumbing:
1 Remove the shipping plastic pipe plugs from the female “To Process” and
“From Process” connections on the back of the portable chiller.
2 Make sure the male pipe threads are clean and new.
3 Wrap the male pipe threads with Teflon tape or pipe dope.
4 Connect the “From Process” valve (factory optional) on the back of the
chiller to the “From Process” tubing that is from the “Water Out” mani-
fold on the mold or process. Start by hand until the threads engage and then
tighten with an appropriately-sized pipe wrench. Tighten only enough to pre-
vent leaks; do not over-tighten.
5 Connect the “To Process” valve (factory optional) on the back of the chiller
to “To Process” tubing that is from the “Water In” manifold on the mold
or process. Start by hand until the threads engage and then tighten with an
appropriately-sized pipe wrench. Tighten only enough to prevent leaks; do not
over-tighten. If process lines are higher than the chiller,
see Appendix G, entitled
Overhead Plumbing Details.

NOTE: The ability of the unit to
maintain process temperature
control depends on the method
of installation.
✐
NOTE: Assure the piping
installation has continuous
flow at all times. If using a
mechanical valve to regulate
process flow you MUST install
a bypass in the process
piping.”
