LAKOS SST & PRO II Installation and Operations Manual Before You Begin.... CAUTION: Water sources vary and may contain impurities that can adversely affect a filter system. Minerals, biological microbes and other impurities must be identified and addressed by each user on a case-by-case basis. Adhere to seasonal shutdown recommendations to minimize problems. Contact your irrigation system dealer for additional information and further recommendations.

LAKOS SST & PRO II Installation and Operations Manual Introduction LAKOS Systems are the industry standard for operating performance and efficiency. Please read this manual carefully to ensure the best performance possible for your system. This manual contains information regarding assembly, start-up, seasonal shut-down, maintenance and troubleshooting. Keep this document for future use and reference. Should you have any questions or concerns, contact your LAKOS representative for further assistance.

LAKOS SST & PRO II Installation and Operations Manual Basics of Operation The Filtering Process From water source (via manifold) ackwash alve Flow ispersion Assembly The filtering process engages the use of a specified sand media to trap foreign matter on the surface layer, allowing filtered water to percolate through the sand media and LAKOS internal v-slotted lateral assembly, discharging at the bottom of each tank to the outlet manifold.

LAKOS SST & PRO II Installation and Operations Manual LAKOS Underdrain:  SST 48 inch tanks- Material is schedule 40 PVC, with injection molded PVC slotted screen as the open area component. Open slotting is internally v-slotted (narrow on the exterior surface, wider on the interior surface) providing a nozzle effect to more effectively introduce water into the tank during backwashing. Open slot size is 0.012 inch in the slotted screen.

LAKOS SST & PRO II Installation and Operations Manual Filter System Installation Align the filter tanks for easy access to the top access and lower-dome clean-out ports; consider the placement of the manifolds and other components. Attach the backwash valves to each tank securely with couplings, using proper lubricant on the gaskets. Be sure that valves are installed with proper connection to the tanks. Attach the inlet, outlet and backwash manifolds with grooved-end couplings.

PAGE 10
LAKOS SST & PRO II Installation and Operations Manual Main Controller Panel Settings The following functions on the main controller panel must also be set properly:  PERIODIC Flush Time This setting insures that the filter system will experience a backwash cycle as set, regardless of the pressure differential setting. In other words, if the contaminant build-up on the filter media does not cause a backwash cycle before this setting, the Periodic timer will initiate a full backwash cycle of all tanks.
PAGE 11
LAKOS SST & PRO II Installation and Operations Manual position. Allow about two minutes for this initial backwash cycle. Manually adjust the solenoid (or move the 3-way valve for manual systems) to stop the backwash cycle for that filter tank. NOTE: The manual adjustment for each solenoid should be OFF for normal operation. ON is the manual override. 4 Initiate a backwash cycle for each of the remaining filter tanks in the filter system, as noted above. No need to adjust the throttling valve again.
PAGE 12
LAKOS SST & PRO II Installation and Operations Manual 3 Drain the filter system completely of all water. It is best to open a coupling connection on outlet manifold of the filter system to ensure that all water is drained from the lowest point of the filter system. 4 All systems: Clean the y-strainer on the water uptake kit. 5. For optimum life expectancy, lubricate the internal shaft of each LAKOS Backwash Valve.

LAKOS SST & PRO II Installation and Operations Manual RE-ASSEMBLING THE SHAFT 1. Be sure that the shaft is clean and free of any debris in the groove. Carefully slide the o-ring 2. 3. 4. 5. 6. onto the shaft and into the groove. Apply a small amount of petroleum jelly to lubricate the o-ring. Clean the inside of the stainless steel bushing. Attach the shaft to the piston, using an allen wrench. Place the spring over the shaft, allowing it to rest on the inside of the piston.

LAKOS SST & PRO II Installation and Operations Manual Troubleshooting PROBLEM POSSIBLE CAUSES SOLUTIONS  Excessive flow through filters, causing  Poor Filtration    “coning” of media sand and/or forcing contaminants through filter outlet. Air in tank(s) may cause disruption of the media sand bed. Incorrect media sand. Excessively high pressure differential before backwashing, which forces contaminants through filter bed.
PAGE 15
LAKOS SST & PRO II Installation and Operations Manual Troubleshooting PROBLEM POSSIBLE CAUSES SOLUTIONS Media Sand Appears Downstream  Incorrect media sand (i.e. too fine  Backwash Valve Leaks and too small) Broken, damaged, or missing lateral.  Obstruction in the valve seat.  Rubber seating disc is worn or damaged. 1. Replace media with proper sized media. 2. Repair or replace laterals of the underdrain. 1. Remove the obstruction. 2. Replace seat disc. 3. Replace diaphragm.
