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 close to the cooling tower to allow for convenience, accessibility and serviceability.
If the filter is to operate year-round, exposure to winter conditions should be a consideration in your location decision.
WARNING
If your TOWER-FLO is to be installed BELOW the static water level of the tower sump:
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 draining the sump if a
power loss should occur during a backwash cycle.
a) In lieu of a balance leg, you may install a normally closed solenoid valve in the waste line to prevent accidental drain-
ing of the tower; consult with TOWER-FLO for proper electrical connections.
WARNING
TFH-18, -24, -30
filters are equiped with self priming pumps. The pump will prime on a straight verticle lift of up to 7 feet. However,
when the need for self priming exists, horizontal pipe runs significantly reduce the ability of the pump to prime itself. When install-
ing your filter in a self priming position, limit horizontal pipe runs 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 condidtion. Always clean accumulat-
ed 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 TFH 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 valve;
3) a skid containing the correct number of bags of filter media (sand) for the size of your filter.
TFH-18:
8, 50 lb. bags
TFH-24:
14, 50 lb. bags
TFH-30:
18, 50 lb. bags
TFH-36:
14, 100 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. Confirm that the direction of rotation switch on the
electric valve actuator is in the “1” position.
