Installation Guidelines
• Prior to installation, flush line to remove debris.
• Install valve horizontally “in line” (cover facing UP), so flow arrow matches flow through the line. Avoid
installing valves 6” and larger vertically. Consult factory prior to ordering if installation is other than
described.
• Install inlet and outlet isolation valves. NOTE: When using butterfly valves, insure disc does not contact
control valve. Damage or improper valve seating may occur.
• Provide adequate clearance for valve servicing and maintenance.
• Install pressure gauge to monitor valve inlet pressure. If On-Off Float Pilot is remotely mounted it should
be field connected with 3/8” minimum copper tubing in accordance with factory piping schematic.
• Float Pilot, Rods, and Ball should be mounted in a field installed “stilling well” for protection against
surface turbulence and interference.
• Additional 12” Float Rods available. Consult Factory.
