Ice Maker - Incoming Water Requirements

Please note that this information pertains to a standalone, undercounter Ice Maker or Ice Machine.

Providing the Correct Water Supply for a Standalone Ice Maker

Incoming water to an Ice Maker should meet the following requirements.

Potable or fit for human consumption.
Must have a conductivity of at least 10 microSiemens/cm.
- For water with high mineral content, water filters are a partial help, as they will remove the suspended solids, but water treatment is needed for the dissolved solids, which are part of the water and cannot be filtered out. We recommend using a water filter on your water inlet line such the in-line filter GXRLQK.
- Reverse Osmosis water can be supplied as long as the water conductivity is no less than 10 microSiemens/cm.
Deionized water is not recommended and could damage the machine.
The water pressure required is a 20 PSI minimum to 80 PSI maximum.
The water temperature should be a 40° Fahrenheit minimum to 90° Fahrenheit maximum.
- Although the machine will function within the listed ranges, it works best at water temperatures between 50° and 60° Fahrenheit.
The recommended water supply tubing is 1/4" OD copper. Stainless steel flex or reinforced PVC tubing may also be used.
