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:

1Remove the shipping plastic pipe plugs from the female “To Process” and “From Process” connections on the back of the portable chiller.

2Make sure the male pipe threads are clean and new.

3Wrap the male pipe threads with Teflon tape or pipe dope.

4Connect 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.

5Connect 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.”
