Blue-White FLEX-PRO A2 ProSeries Peristaltic Pump - Manual (Page 27)

Pump has a built in 3 amp alarm output relay. Relay is pre-configured to energize on tube failure detection (TFD)
and on Flow Verification Sensor (FVS).
A Flow Verification Sensor must be installed and configured for relay to trigger on no-flow conditions.
Prior to service, pump clean water through pump and suction / discharge line to remove
chemical.
Always wear protective clothing, face shield, safety glasses and gloves when working on or
near your metering pump. Additional precautions should be taken depending on solution
being pumped. Refer to MSDS precautions from your solution supplier.
Reverse rotation of pump; press and hold REVERSE ROTATION button until rotor begins rotating in opposite
direction. This process can be used for many reasons throughout various industries.
Two reasons for reversing current rotor rotation; to purge chemical from tubing and to extend tube life.
Plan ahead before reversing rotor rotation. If check valves are installed, make necessary arrangements to allow
back flow.
If your desire is to simply extend tube life:
Typically tubing fails on outlet side (pressure side) of tube assembly in pump head.
Failure to install check valves in their proper flow direction can cause excess pressure
(PSIg) build up in system and can result in tube rupture.
Always use extreme caution and ensure proper connections when using this feature.
Swap Inlet
and Outlet
ON R T F
Reversing rotation, moves outlet side (pressure side) to
opposite side of tube assembly, greatly increasing tube life.
Stop pump before tube failure occurs.
Disconnect power from pump. Carefully purge any pressure
in discharge line of pump. Disconnect suction end tubing and
discharge end tubing from pump head tubing.
IMPORTANT! Swap sides of suction (inlet) and discharge
(outlet) tubing. No need to remove Pump Head Cover.
Double check all connections before starting pump.
