3. 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 STS system until the system is placed
in its final operating position.

IV. INSTALLATION OF STS SERIES MEDIA FILTERS
1. A suitable foundation or pad must be provided to support the full operating
weight of the STS system, including liquid (see media sand chart above).
Use caution when moving the STS system into position. Move the system
only by lifting the entire skid (forklift or crane/hoist). Never try and lift the
equipment with hooks or straps attached to system piping or manifold, as
damage could occur to the system. Anchor the unit to the foundation to
prevent vibration and/or movement.
2. All STS systems required flooded pump suction for proper operation.
Please make sure that all inlet piping to the system is located to ensure
that the pump is flooded with water at all times. If you system is equipped
with a self priming pump this will not apply.
3. The control panel must be wired for the proper voltage and rotation of
the pump (see wiring diagram in control box door). All wiring should be
done by a licensed electrician in accordance with local codes. Motor
nameplates should be referenced for voltage, amperage draw, cycles,
phase, speed and other motor information.
4. Piping connections to and from the STS system should be of at least the
same pipe size as the STS inlet and outlet connections. Do not install
smaller diameter pipe anywhere on the inlet, outlet, or backwash lines.
Check local codes to determine if appropriate backflow prevention is
necessary at the inlet.
