Installation
4.1
Mounting Location
Choose an area located near chemical supply tank, chemical injection point, and electrical supply. Install pump
where it can be easily serviced.
!
316SS Mounting brackets are included. Mount pump to a secure surface using enclosed mounting hardware.
!
Mount pump close to injection point. Keep inlet (suction) and outlet (discharge) tubing as short as possible.
Longer discharge tubing increases back pressure at pump head.
!
A back flow prevention check valve is recommended at the discharge of the pump to prevent system fluid from
flowing back through the pump during tube replacement or if the tube should rupture.
!
A pressure relief valve is recommended at the discharge of the pump to prevent premature wear and damage to
the pump tube in the event the discharge line becomes blocked.
!
The Flex-Pro does not require back pressure. Pressure regulator valves are not required. Keep the discharge
pressure as low as possible to maximize tube life.
!
An anti-syphon valve is not required. Syphoning cannot occur.
