3-10 Automatic Water Make-Up Option

The chiller may be connected to an automatic make-up system if the optional package (float switch, pressure regulating, pipe fittings, solenoid valve and 1/2” NPT city water make-up connection) is factory installed.

Refer to the typical piping schematics on pages 64-69 in the Appendix for additional components necessary for this installation.

Prevent reservoir over-pressurization by setting the required pressure-regulating valve to limit make-up water pressure to less than 5 psi. The reservoir must remain vented to the atmosphere.

If the automatic make-up system is connected to a city water system, make provisions to prevent backflow contamination. Install an approved backflow preventer in accordance with local codes.

Caution! Adding straight city water into a glycol/water mixture dilutes the solution and eventually leads to system freeze-up. Damage from freeze-up is not covered by the warranty.

To prevent system freeze-up in automatic make-up applications, we recommend using either a chemical feeder or make-up reservoir to replenish glycol. Contact the sales department for more information about these configurations.
