FTS SERIES SAND FILTERS

INSTALLATION & OPERATING MANUAL

LAKOS FTS Series Sand Filters are specifically intended for use in full-stream or

side-stream applications. For side-stream, we recommend the industry

standards of 10% to 20% of full-stream flow. However, you are free to operate at

higher or lower percentages, based on your specific application conditions and

criteria. Side-stream may be applied by tapping from a mainstream line or by

tapping the basin/remote sump to achieve a given turnover rate.

LAKOS does not recommend the FTS Series for basin/remote sump sweeping

applications. The proper use of this technique requires a specific sweeping

design involving HydroBoosters and the proper flow/pressure to ensure

performance. More specifically, LAKOS recommends the LAKOS TC Series for

basin/remote sump sweeping, featuring LAKOS Sand Separators. This

equipment is simply better suited for applications where settleable solids are

involved.

Maximum operating pressure for a LAKOS FTS System is 50 psi (3.4 bar). Do

not install this system into applications with higher pressures.

DELIVERY INSPECTION

• Immediately inspect the system upon arrival for any damage that may have occurred

during shipping. Look for crate damage, pierced or torn boxes or any other signs of

handling, which may suggest damage to the system. Shipping damage must be

reported to the carrier for direct handling. LAKOS is not responsible for shipping

damage.

• LAKOS FTS Series Systems are shipped with all major components assembled onto

the skid. Selected small items, such as the pressure gauges, may be removed and

inserted in the controller box for shipping.

• LAKOS sand media is shipped separately in 100 lb. (45 kg) bags. The exact number

of bags is determined by the actual system size (see chart below). Do not introduce

media sand into the FTS System until the system is placed in its operating position.

INSTALLATION PROCEDURES 1. A suitable foundation or pad must be provided to support the full operating weight of the FTS System, including liquid. See chart on page 1. Anchor the unit to the foundation to prevent vibration and/or movement. 2. Use caution when moving the FTS System into position. Forklift only by the skid. If hoisting is necessary, do not attach hooks or straps to the inlet piping/manifold. 3. FTS System requires a flooded pump suction to ensure proper pump operation. 4.

refer to the Triton & User's 12. ADDING FILTER SAND: Please Remove upper tank shellInstallation by first loosening theGuide flangeincluded. bolts around the center of the tank. To equalize flange stress, loosen bolts alternately (opposite sides of the tank). Remove all bolts. Carefully lift the upper tank shell straight up, using care not to damage the cord ring seal around the flange. Inspect the underdrain to be sure all parts and connections are secure.

INSPECTION ROUTINES Every 48 hours … • Visually inspect the FTS System. • Check for unusual noise or vibration. • Observe pressure gauges for normal readings. Every 30 days … • Check the pre-strainer and clean if necessary. • Observe a backwash cycle for duration time and the condition of backwash water. It should be relatively dirty at first and clean just before the backwash cycle ends.

Note damage or shortage on freight bill (bill of lading); immediately file claim with carrier. 2. EXTERIOR — Pay particular attention to conduit box, 4. external hardware and accessories. Touch up abrasions or scratches with approved paint. 5.

OPERATION Pre-Start — Before initial start of the pump, check as follows: 1. The rotation must be checked upon installation. Close, then break the contacts quickly and observe the rotation of the exposed portion of the rotating parts. Rotation must agree with the rotation arrow on the motor. For all pumps, the standard rotation is counterclockwise when viewed from the suction end. Motor wiring is easily changed in the field.

Push out stationary member of mechanical seal. It is not necessary to remove the cast iron disc from the motor to replace the seal. B.) Reassembly: CAUTION: The mechanical seal is a precision product and should be handled accordingly.

9. Remove impeller from shaft, being careful not to lose the impeller key, spring and gasket. If impeller is difficult to remove, it may be necessary to use a bearing puller to remove. 10. Pry off rotating member of mechanical seal from sleeve by using two (2) screwdrivers. Be careful not to damage the pump cover. See Figure 5. 6. 7. 8. Figure 5 11. Remove pump cover from cast iron disc. (There isn’t any hardware used to attach cover to disc.
