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 ﬁ lter tank inlet is 20 psi and MAXIMUM water pressure is 100 psi. If you have a private

well, the gauge on the pressure tank will indicate the high and low system pressure. Record your water pressure data below:

WATER PRESSURE:

Low___psi High___psi

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Do not install if water pressure exceeds 100 psi (689 kPa). If the system water pressure exceeds 100 psi, the installation

must use a pressure limiting valve. Contact a licensed plumbing professional if you are uncertain how to check your water

pressure.

2) The pumping rate of your well pump must be sufﬁ cient for satisfactory operation of the Hydro-Charger and to BACKWASH the

ﬁ lter. Refer to SPECIFICATIONS AND OPERATING DATA for the backwash requirement for each model. To measure the pump-

ing 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 reﬁ ll pressure tank (when pump shuts off). This ﬁ gure represents CYCLE TIME.

b. With the pressure tank full, draw water into a container of known volume, measure the number of gallons drawn until the

pump starts again. This is DRAW-DOWN. Divide this ﬁ gure 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 data in the following formula:

DRAW-DOWN ______ (gals.) ÷ CYCLE TIME ______ (secs.) x 60 = PUMPING RATE ______(gpm)

EXAMPLE:

CYCLE TIME is 65 secs.; DRAW-DOWN is 6 gals.; then PUMPING RATE equals: 6 gals. ÷ 65 secs. x 60 = 5.5 gpm

IMPORTANT NOTE

The addition of the Hydro-Charger to the pumping system or plumbing and other water treatment devices (such as an acid neutral-

izer) may reduce the ﬂ ow rate at the ﬁ lter drain to an inadequate level to properly backwash the ﬁ lter. If you are uncertain whether

your ﬂ ow rate is adequate, contact your dealer BEFORE installing your Chem-Free Iron Reduction ﬁ lter, so that corrective action,

if required, may be taken.

Locate Iron Reduction System Correctly:

Select the location of your ﬁ lter 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 ﬂ oor or laundry tub drain.

3) Locate in correct relationship to other water conditioning equipment (See Figure 1, in Section 3).

4) Filters and softeners should be located in the supply line BEFORE the water heater. Temperatures above 100° F (38° C) damage

ﬁ lters and softeners and will also void the factory warranty.

5) Do NOT install a ﬁ lter 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 sufﬁ cient space around the unit for easy servicing.

7) If your water sources is a community water supply, a public water supply, OR you wish to bypass water used for a geothermal

heat pump, lawn sprinkling, outbuildings or other high demand applications, refer to Figure 1 for additional equipment required.

Also, refer to the Special Instructions following installation procedures.

The Importance Of Your Pressure Tank:

The pressure tank found on private well systems becomes an integral part of the Chem-Free Iron Reduction System by providing

necessary mixing and “residence time” to the “Hydro-Charged” water. While the Chem-Free Iron Reduction Filter System will perform

satisfactorily with either a captive-air (bladder) type pressure tank or a standard air-to-water type with an air volume control (air-relief

valve), the bladder type requires more careful adjustment of the Hydro-Charger to prevent gases from collecting in the pressure tank

and the head area of the ﬁ lter tank.
