CHECK YOUR WATER PRESSURE AND PUMPING RATE
Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:
1. Minimum water pressure required at the filter tank inlet is 20 psi. If pressure is over 50 PSI, a pressure reducing valve
must be installed in the water supply line ahead of the hydro-charger (Fig. 1, 2 or 3).
2. The pumping rate of your well pump must be at least 5 gallons per minute (gpm) for satisfactory operation of the
hydro-charger. In addition, the pumping rate must equal the required backwash flow rate of your model (see below for
backwash flow rates). To measure the pumping rate of your pump, follow these instructions:
a) Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and
measure time (in seconds) to refill pressure tank (when pump shuts off). This figure represents cycle time.
b) With the pressure tank full, draw water into a container of known volume, and measure the number of gallons
drawn until the pump starts again. This is draw-down. Divide this figure by cycle time and multiply the result by
60 to arrive at the pumping rate in gallons per minute (gpm). To aid in your calculation, insert the date in the fol-
lowing formula:
DRAW-DOWN ______ ÷ CYCLE TIME _______ x 60 = PUMPING RATE ________
(gals) (secs.) (gpm)
EXAMPLE: CYCLE TIME is 53 secs.; DRAW-DOWN is 6 gals.; then, PUMPING RATE equals:
6 gals.
÷ 53 secs. x 60 = 6.8 gpm
See chart on page two for minimum flow rates.
NOTE: If your pumping rate is inadequate, do not install your filter until problem is corrected.
LOCATE WATER CONDITIONING EQUIPMENT CORRECTLY:
Select the location of your filter tank with care. Various conditions which contribute to proper location are as follows:
1. Locate as close as possible to water supply source.
2. Locate as close as possible to a floor or laundry tub drain.
3. Locate in correct relationship to other water conditioning equipment (see Fig. 1, 2 or 3).
4. Filters and softeners should be located in the supply line before the water heater. Temperatures above 120°F damage
filters and softeners, and will void the factory warranty.
5. Do not install a filter or softener in a location where freezing temperatures occur. Freezing may cause permanent
damage to this type of equipment, and will void the factory warranty.
6. Allow sufficient space around the unit for easy servicing.
7. If your water source is a community water supply, a public water supply, or you wish to bypass water used for a
geothermal heat pump, lawn sprinkling, out-bindings or other high demand applications, refer to Figs. 2 or 3 for addi-
tional equipment required. Also, refer to the NOTE following Step 11 or Sec. 3, Installation.
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 “Hydro-Charged” water. While the iron filter will perform better on a standard water to air
pressure tank, it will perform satisfactorily on a captive air (bladder) type pressure tank. The bladder type requires more
careful adjustment of the Hydro-Charger and the careful location of the air relief valve.
If cycle time on pumping system is less than 30 seconds and under severe operating conditions (low pH, high iron, man-
ganese, and small concentrations of sulfur), a standard air-to-water type pressure tank with an air-relief valve must be
used (if a bladder type tank is already in place — do not remove it — install the air-to-water pressure tank between the
Hydro-Charger and the bladder type tank).
NOTE: If your pressure tank (or any part of the water system) is not functioning properly, corrective action must be taken
before installation of your iron filter.
