Water Heater

If the water heater has been exposed to both iron and hardness for a long period of time, replacement of the heater tank

may be the only practical solution to prevent continued staining originating from this source.

After completing the installation of the chemical free iron filter, clean the water heater by following these instructions:

1. Shut off the energy supply to the water heater and close the heater inlet water valve.

2. Drain hot water tank completely. Open inlet water valve, allowing heater tank to be refilled with iron-free water.

Continue flushing until the water runs clear to the drain.

3. If, after approximately 30 minutes of flushing, water does not clear, terminate the flushing operation. Refill hot water

heater with water and pour approximately 1/2 gallon of household bleach into the top of the heater tank. Allow

bleach solution to stand in tank for 20 to 30 minutes. Flush the tank again until water is clear at the drain. Turn

energy supply on.

NOTE: If water does not clear in approximately 10 minutes, water heater should probably be replaced.

Backwashing Instructions

To Calculate Backwash Frequency

To ensure adequate reserve capacity and prevent loss of water pressure between backwashes the figure of 15,000 not

the full 30,000 ppm capacity is used to calculate backwash frequency. Determine your backwash frequency as follows:

Estimate the daily iron removal requirements using the following calculation:

Number of people in the family

x 75 gallons of water per person

+ Number of gallons for special use (if applicable)

= Number of gallons of water required per day

x Iron concentration - ppm

= Daily iron removal requirement

Establish backwash frequency using daily iron removal requirements to complete the following calculation:

15,000 ppm iron removal capacity

÷ Daily iron removal requirement - ppm

= Number of backwashes required in a 10 day schedule

Example: You have 4 people in the family, 8 ppm of iron and a swimming pool requiring 46 gallons of water per day.

4 People in the family

x 75

Gallons of water per person

300 Gallons of water for family

+ 46

Gallons of water for the pool

346 Gallons of water required per day

x 8 Iron concentration - ppm

2,768 Daily iron removal requirement - ppm

15,000 Iron removal capacity - ppm

÷ 2,768

Daily iron removal requirement - ppm

5.4 Backwash frequency - days

The calculation indicates the need to backwash every 5.4 days. The control should be set to backwash every 5th day.

Dishwasher

Consult your owner's handbook and follow the manufacturer's instructions.

Toilet Flush Tanks

Prior to commencing installation of the filter system, pour 4 to 6 oz. of resin mineral cleaner Iron-Out or inhibited muriatic

acid into flush tanks and bowls and let stand. When installation is completed, flush toilets several times with iron-free

water. If iron deposits or stains remain, repeat procedure until clear.

Water Pressure

Your chemical free iron filter system is designed to operate under normal water pressures from 20 psi to 100 psi.
