Page 3: Description
Recommended Applications Tekleen filters are ideal for filtering out silt, scale, sand, rust, dirt and organic material like algae, zebra mussels, and clams from virtually all types of water sources. -
Page 4: Design Features
Among the many features of the LPF models is the avoidance of the danger of forcing contaminated water back into the system, which often happens with sand filters. Tekleen filters will deliver clean water or no water at all. The most predominant feature is its ability to remove organics such as algae and other suspended particles. -

Page 6: Installation And Hook-Up
The positioning of the filter tank should be determined by the disposal of waste water and to allow easy access and removal of filter element (Consult manufacturer for required clearances). The Tekleen filter can rest on the inlet and outlet flanges or can be mounted on a stand if desired. -
Page 7: Gb6, Dp Gauge, And Electric Ball Valve Connection
GB6, DP Gauge, and Electric Ball Valve Connection Before power is applied to the electronic controller, make all connections between controller, DP Gauge, and electric ball valve (see page 18). 1. BALL VALVE: Plug controller into appropriate power source. Activate manual start switch and visually inspect the open and close movement of the ball valve. -
Page 8: Operation And Adjustments
Electronic controller should be sealed completely to avoid moisture from entering. This will prevent possible shorting of circuits. or more operating details and set-up, please refer to your electronic rinse controller manual. SECTION III OPERATION AND ADJUSTMENTS Start-Up During start-up, the block valve at the filter inlet should be cracked open to prevent a surge of pressure across the filter when the pump is started. -
Page 9: Backflush Requirements
Back-Flush Requirements The filter needs a minimum flow and pressure during the backflush process to guarantee a fully effective cleaning. The minimum flow depends on the size of the filter’s flush outlet and the pressure during backflushing. The table below gives an indication of the required flows. -
Page 10: Maintenance
SECTION IV MAINTENANCE Filter Cleaning Periodic cleaning and inspection of the coarse screen, if supplied, is necessary for removal of large particles trapped in the chamber. It is also recommended that the fine screen be inspected during coarse screen cleaning. In hard water applications, it is beneficial to wash the fine screen in a mild acid. -
Page 11: 4.4 Periodic Inspection
4.4 Periodic Inspection The following parts should be inspected annually for wear and tear and should be replaced if necessary: Cover Seal Coarse Screen Fine Screen O-rings Piston Electric Motor Packing Dirt Collector Upper Bearing Lower Bearing Air/Water Connections SECTION V TROUBLESHOOTING GUIDE Problem: Excessive pressure drop through filter without flushing. -
Page 12: Frequent Continuous Flushing While Filling Main Pipeline
Problem: Frequent/continuous flushing while filling main pipeline. POSSIBLE CAUSE Downstream pressure is not available to provide vacuum cleaning power. Rapid-filling flow rate exceeds the controllers’ pressure differential. SOLUTION Partially close downstream mainline valve; filter inlet gauge should read 15 psi. POSSIBLE CAUSE Filter may have been shut down “dirty”... - Page 13 POSSIBLE CAUSE Screen may be partially plugged. SOLUTION Perform Superflush as described above in section 5.2. POSSIBLE CAUSE Dirt collector may be jammed which results in only cleaning the screen area that is directly in front of the nozzles. SOLUTION Open tank and check for free movement of dirt collector mechanism.
-
Page 14: Screen Will Not Clean Properly
Problem: Screen will not clean properly. POSSIBLE CAUSE Restriction in flushing valve dump line due to long “run” distance (e.g., running uphill, 2” line more than 20’ long, 2” line has more than one elbow). SOLUTION Increase pipe size, remove any elbows, avoid elevation gain of pipe after flush valve. -

( see controller manual). ASME CERTIFIED FILTERS ASME certified filters for the LPF series are available on special order. The lead time on these is approximately 30 to 90 days. III. -
Page 16: Appendix Ii System With Discharge To Atmosphere
Appendix II System with Discharge to Atmosphere If the filter freely discharges to the atmosphere, it is recommended that a control valve be installed at the filter discharge. Depending on the process upstream of the filter, the flow may be higher than the filter handling capacity. In this case, the control vale at the outlet would be used to create a back pressure on the system and control the flow across the filter. -
