Shut-Down and Winterizing

The HydroGuard controller is designed to keep the probes submerged even if there is no flow to the
controller. However, if the controller is going to be offline for an extended period of time and/or exposed to
freezing temperatures, it must be winterized to prevent damage to the controller and the probes.
1. Remove each probe from the flow cell
2. Fill the rubber caps (that were on the new probes) with tap water or preferably KCl (potassium
chloride) solution and insert over the end of each probe.
3. Screw the plastic cap over the top of each probe to protect the connector.
4. Store in a safe location that will not drop below freezing, preferably in the original probe box for
additional protection.
