Guardianf

Slime is a leading cause of ice machine breakdowns and biological growth is a health concern. The Guardianf system releases chlorine dioxide on a controlled basis to inhibit the growth of bacteria and fungi that form slime and cause malodors in the food zone of ice machines.

The Guardianf will not control mineral or other water borne buildup. Your water quality will determine the length of time before mineral buildup affects ice machine performance. Mineral buildup must be removed as often as necessary to ensure trouble-free operation of the ice machine.

The Guardianf sachet holder is included with the sachet packets. Refer to installation/replacement procedure to install/change sachet holder/ packet.
