STEP 2. LOCATE FILTER
Place the TOWER-FLO Filter System on a firm level surface. The TOWER-FLO Filter does not need to be anchored,
unless required by local code. Select a location that allows for convenience, accessibility and serviceability. If the filter
is to operate year-round, exposure to winter conditions should be a considered in your location decision.
WARNING
If your TOWER-FLO is to be installed BELOW the static water level of the tower sump,
in either an independent sidestream or a slipstream:
1
) Install valves on the inlet, waste and outlet piping to permit removal or maintenance of filter system without draining the tower.
2) Install a balance leg with an air gap in the waste line (as shown below) to prevent gravity from accidently draining con-
denser water should power loss occur to the control valves while in a backwash cycle.
a)
In lieu of a balance leg with air gap, you may install a normally closed solenoid valve in the waste line to prevent
accidental draining of the tower; consult TOWER-FLO for a valve and its proper electrical connections.
WARNING
Your TOWER-FLO Filter is equiped with a self priming pump. This pump will prime on a straight vertical lift of up to 7 feet.
However, when the need for self priming exists, horizontal pipe runs above water source water level significantly reduce the
ability of the pump to prime itself. When installing your filter in a self priming position, limit horizontal pipe runs above water
level to a
maximum of 18 inches.
If this limit is not practical for your installation, we recommend the use of a foot valve in the
suction line in order to maintain self priming capability.
WARNING
TOWER-FLO
Filters should never be installed on a
dirty basin or reservoir. Installing the filter on a dirty
basin will cause a nearly constant backwash condid-
tion. Always clean accumulated mud, silt, and debris
from the bottom of the basin or reservoir BEFORE
installation of the sidestream filter.
STEP 1. UNPACK AND INSPECT THE FILTER
New Tower-Flo
®
Series TFW Filters should have been unwrapped and thoroughly inspected for freight damage
upon receipt at your receiving dock, per the receiving stickers affixed to the filter’s protective shrink-wrap. Freight
damage issues must be addressed with the freight carrier when accepting delivery.
As you prepare to install your filter, confirm that you have:
1) the skid mounted filter system;
2) a cardboard box containing the pump pre-strainer and the filter vessel’s air release and pressure relief valves;
3) a skid containing the correct number of bags of filter media (sand) for the size of your filter.
TFW-20 = four 50 lb. bag
TFW-24 = six 50 lb. bags
TFW-30 = nine 50 lb. bags
Re-inspect the filter system to check that all plumbing connections, especially union nuts, are hand tight and that
there are no cracks or fractures in any of the external piping (NOTE: over tightenin can crack fittings). Confirm that
the three position toggle switch on each of the two electric valve actuators is in the “ON 1” position.
