Before, and after, installing heads*
• 1. Before installing any heads, flush
lines to remove all dirt, sand, debris*
2. After all heads are installed, run the
last Digital Sprinkler(s) on the end of
all pipe runs for several minutes to
remove all air from the system.
3. Also run all Valve zones to remove
all air from the system
Trapped / deadhead air anywhere in
the system acts as an “air piston”,
causing calibration errors
