The Importance of Your Pressure Tank
The pressure tank found on private well systems becomes an integral part of the filter system by providing necessary mixing
and "contact time" to the "hydrocharged" water. While the iron filter will perform better on a standard air-to-water pressure
tank, it will perform satisfactorily on a captive air (bladder) pressure tank. The bladder tank requires more careful adjustment
of the hydrocharger and careful location of the air relief valve. (see Fig. 7 and 8, Page 7).
If cycle time on pumping system is less than 30 seconds and severe operating conditions exist (flow pH, high iron,
manganese, and small concentrations of sulfur), a standard air-to-water pressure tank with an air-relief valve must be used (if
bladder tank is already in place – do not remove it – install the air-to-water pressure tank between the hydrocharger and the
bladder tank).
NOTE: If your pressure tank (or any part of your water system) is not functioning properly, corrective action must be taken
before installation of your iron filter.
Facts to Remember When Planning Your Installation
1. All installation procedures must conform to local and state plumbing codes.
2. All water must pass through the hydrocharger, pressure tank and the filter, or refer to the special instructions for a split-
stream installation on Page 7. (System may malfunction if these instructions are ignored.)
3. If lawn sprinkling, a swimming pool, geothermal heating/cooling or water for other devices/activities is to be treated by the
filter, a larger model filter must be selected to accommodate the higher flow rate demands of these items. The pumping
rate of the well pump must be sufficient to accommodate these items plus the backwash requirement of the filter. Consult
your dealer for alternative instructions if the pumping rate is insufficient.
4. Remember that the filter inlet is attached to the pipe that supplies water (i.e. runs to the pump) and the outlet is the line
that runs toward the water heater.
5. Before commencing installation, it is advisable to study the existing piping system and determine the size, number and
type of fittings required. Typical system schematics shown in these instructions (Fig. 1, 2, or 3, Page 5), will be of
assistance
NOTE: if the plumbing system is used as the ground leg of the electric supply, continuity should be maintained by
installing ground straps around any non-conductive plastic piping used in installation.
6. When utilizing a constant pressure or VFD pump system you will require the addition of an air pump and vent tank kit
#978003 for 115 volt or 978004 for 230 volt systems. A flow switch #79980 will also be required to run the air pump, see
Figure 4 for installation diagram.
Proper installation sequence of water conditioning equipment is very important. Refer to the diagrams following for your
particular water supply.
NOTE: The Braukman air vent is not approved for use in the State of Wisconsin. An approved air to water tank
and/or air vent should be used with this application in the State of Wisconsin.
