11. Install auto-dRaIns (fReezInG aReas onlY)
Where freezing is a concern we recommend you install auto-drain valves at the low spots in the system
and on the downhill ends of sloping pipes. The auto drains must be at the lowest points in the line.
The timer provided can be mounted indoor or outdoor. For indoor installation refer to the diagram below
and the next page. For outdoor installation use a licensed professional electrician.
