50 valves or less, or every 1000 ft or less,
whichever comes first.
Two tower box mounting methods are shown, choose
the tower box mounting method based on the appli-
cation.
• Drive unit mounting
• Span pipe mounting
NOTE
• Make sure that the power supply tower box
and/or the mounting does not interfere with
intermediate tower box linkage or mechani-
cal corner run cycle box linkage.

four drive unit mounting brackets using one con-
