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” or higher 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 gauges to monitor valve inlet and outlet pressure.
• Connect Solenoid to proper electrical source in compliance with local electrical codes.
