4.0 Installation

CAUTION

Flex-Pro

Risk of chemical overdose. Be certain pump does not overdose chemical during backwash and periods of no flow in circulation system.

CAUTION

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.

All diagrams are strictly for guideline purposes only. Always consult an expert before installing metering pump on specialized systems. Metering pump should be serviced by qualified persons only.

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. Keep the discharge pressure as low as possible to maximize tube life.

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).

Page 11

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.

Confirm the FVS flow range - Flow Verification Sensor (FVS) will only function within its operating range. See chart for available ranges.

10.0 Pump Tube Timer

Flex-Pro has a built in Pump Tube Timer. Timer starts when rotor is rotating and stops when rotor is idle. To view current Pump Tube Timer value, press the START and DOWN buttons and the Tube Timer screen will appear. Screen will display current Pump Tube Time in run-time hours. The Tube Timer screen will display for 4 seconds and then switch back to the previous operating display screen.

While displayed, press DOWN arrow button twice to reset Pump Tube Timer to zero.

When replacing pump tube, pump will ask you if you’d like to reset Pump Tube Timer. If you choose YES, screen will display current Pump Tube Time for 5 seconds before timer is reset to zero.

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.

Flex-Pro

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, 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 assembly. 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.

Chemical from tube failure

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.

Flex-Pro

13.0 Reverse Rotor Rotation

Increase tube life with this feature!

Page 13

CAUTION

Prior to service, pump clean water through the pump and suction / discharge line to remove chemical.

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.

CAUTION

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.

If your desire is to simply extend tube life:

Typically tubing fails on outlet side (pressure side) of tube assembly in pump head.

Reversing rotation, moves outlet side (pressure side) to opposite side of tube assembly, greatly increasing tube life.

Outlet

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.

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.

]

Although not necessary, 100% silicon lubrication may be used on the roller assembly and tube assembly.

]

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.

Insert suction fitting into pump head. Remove your fingers from pump head. Start pump by pressing START button. Grab hold of Tube Installation Tool and use it to leverage tubing into pump head.

Introduce tubing into pump head while the rotor is rotating. Avoid using fingers to guide the tubing. Stop pump at anytime by pressing STOP button. Start pump by pressing START button.

PULL

Continue to follow rotation of rotor while directing tube into pump head. At this point, you may need to pull Tube Installation Tool to stretch tubing into position. Let rotor spin a few rotations while pulling Installation tool so fitting can be properly installed.

Continue to pull Tube Installation Tool to allow enough room to slide discharge fitting into pump head tongue and groove. Once discharge fitting is secured in pump head, stop pump by pressing STOP button. Replace pump head cover. Pump will ask you if you’d like to reset tube timer. If you choose yes, current tube time will display for 5 seconds before resetting to zero. Make note of your displayed tube life. Select Yes again to reset tube life timer.

Re-attach Pump Head Cover using the four Thumb Screws.
