4.0 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.
4.2 Dimensions

Flow Verification System (sensor sold separately)
Flex-Pro is equipped with a Flow Verification System which is designed to stop
pump and energize a 6 amp relay in event sensor does not detect chemical
during pump operation. This could indicate a clogged injection fitting, empty
chemical solution tank, worn pump tube, loose tubing connection, etc.
To allow pump to clear any gasses that may have accumulated during stopper
operation (such as with chlorine), an alarm delay time value from 1-255
seconds must be programmed (An alarm delay value of 000 seconds disables
FVS system).
If FVS alarm occurs, pump will stop, send an external signal (if setup), and
screen will flash FVS with an alarm icon.
To clear FVS alarm, you must press START button or re-cycle power (unplug
power to pump, then plug back in).
Install FVS Flow Sensor - Flow Verification Sensor (FVS) should be installed
on the inlet (suction) side of the pump tube. Sensor includes a PVC tubing
insert, located inside sensors female thread connection, that is designed to
seal sensor onto pump tube inlet adapter. Thread sensor onto pump tube until
tubing insert is snug against pump tube inlet fitting - do not over-tighten.

11.0 TFD (Tube Failure Detection)
Flex-Pro is equipped with a Tube Failure Detection System which is designed to
stop the pump and provide an output alarm (see Output menu) in the event pump
the tube should rupture and chemical enters the pump head. The pump will
detect a chemical with a conductivity reading greater than 500 microsiemens.
Chemicals with a conductivity of less than 500 microsiemens will not be
detected.
This patented system is capable of detecting the presence of a large number of
chemicals including Sodium Hypochlorite (Chlorine), Hydrochloric (muriatic)
Acid, Sodium Hydroxide, and many others. The system will not be triggered by
water (rain, condensation, etc.) or silicone oil (roller and tubing lubricant).
If system has detected chemical, pump tube must be replaced and pump head
and roller assembly must be thoroughly cleaned. Failure to clean the roller
assembly will void warranty.
If TFD alarm occurs, pump will stop, close an alarm output (if configured), and
screen will flash TFD with an alarm icon.
Confirm Chemical Detection - To determine if your chemical will be detected by
the system, remove the pump head cover and the pump tube and roller assem-
bly. Place a small amount of chemical in the bottom of the pump head - just
enough to cover the sensors. Replace the pump head cover only. When asked if
the tube was replaced, select “no” and press enter. Turn on the pump (press
start). If the TFD system detects the chemical, the pump will stop after a two
second confirmation period and the TFD Alarm screen will display. If the TFD
system does not detect the chemical, the pump will continue to run after the
confirmation period. Carefully clean the chemical out of the pump head being
sure to remove all traces of the chemical from sensor probes. Replace the roller
assembly and tubing. Replace the pump head cover. Press the START button to
clear the alarm condition and restart the pump.

If you choose YES, screen will display current Pump Tube Time for 5 seconds before
timer is reset to zero.
12.0 Alarm Relay
Pump has a built in 6 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.

13.0 Reverse Rotor Rotation
Increase tube life with this feature!
!
CAUTION Prior to service, pump clean water through the 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.
!
CAUTION
Pump rotor can reverse rotation by pressing REVERSE ROTATION button. 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 checkvalves 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 checkvalves 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.
!
CAUTION
Swap Inlet
and Outlet
O
N
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.

14.0 How to Maintain Pump
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.
!
CAUTION
Routine Inspection and Maintenance
Pump requires very little maintenance. However, pump and all accessories should be checked weekly. This is
especially important when pumping chemicals. Inspect all components for signs of leaking, swelling, cracking,
discoloration or corrosion. Replace worn or damaged components immediately.
Cracking, crazing, discoloration and the like during first week of operation are signs of severe chemical attack. If this
occurs, immediately remove chemical from pump. Determine which parts are being attacked and replace them with
parts that have been manufactured using more suitable materials. Manufacturer does not assume responsibility for
damage to pump that has been caused by chemical attack.
How to Clean and Lubricate Pump
Pump will require occasional cleaning. The amount will depend on severity of service.
]When changing pump tube assembly, pump head chamber, roller assembly and pump head cover should be wiped
free of any dirt and debris.
]Pump head cover bearing may require grease periodically. Apply a small amount of grease (Aeroshell aviation
grease #5 or equivalent) when necessary.
]100% silicone lubrication may be used on the roller assembly. Refer to Blue-White.com/videos for roller assembly
maintenance video instructions.
]Periodically clean injection/check valve assembly, especially when injecting fluids that calcify such as sodium
hypochlorite. These lime deposits and other build ups can clog fitting, increase the back pressure and interfere with
check valve operation.
]Periodically clean suction strainer.
