Winterizing
The Hydrofuse system can easily be winterized. To winterize the system follow the steps below:
1. Remove the electrical connectors for the float switch taking care to press the small release lever and only
pull on the plastic connectors (1) – never pull on the wires themselves or they may pull out of the
connectors.
2. Push on the blue ring and remove the pump pick up tube from the reservoir (2).
3. Remove the reservoir from the machine (3).
4. Next turn off the Irrigation system water supply and bleed down pressure in the system by turning on
one of the zones.
5. Now take the pipe that you removed from the reservoir and blow through it with compressed air with at
least 30 PSI (4) to clear the lines and pump of all liquids, which will now be in the irrigation piping.
6. Lastly, blow out the Irrigation system piping as you normally would to winterize the Irrigation system.
7. When you are done store the reservoir in a place not subject to freezing temperatures.
Spring Start Up
When the temperatures are consistently above freezing reverse the above steps, and then prime the system
as described in section (1) of the “Priming, Testing, and Setting the Timer” section above.
