The following procedures are guidelines only but have proven successful in most instances. Under no circumstances should any procedure
outlined below be followed if contrary to the appliance manufacturer's instructions. Should there be any questions concerning the advisability
of performing a procedure, it is strongly recommended the manufacturer's authorized service outlet be consulted prior to performing the pro-
cedure.
The plumbing system and water using appliances that have been exposed, even for a short time, to iron-fouled water need to be cleaned of the precipitated iron that
has collected in them or iron "bleed" (staining) will continue to be a problem.
Depending on the amount of iron in the water and the length of time the water system has been exposed to iron fouling, select the following procedures that apply
to the type of system and appliances that need cleaning to help assure better quality water at the points of use.
It is not uncommon that a softener was installed in an effort to reduce ferrous ("clear water") iron from the water supply. Typically, a softener will reduce some
ferrous iron until the resin bed becomes fouled to the extent that it will lose both hardness reduction capacity and the limited capacity for iron reduction. This is the
condition to expect the softener to be in when planning a system clean-up.
Prior to closing main supply valve or turning power off to a private well system and preparatory prior to installing the Iron Reduction System on a system where a
softener has already been installed, do the following:
1)
Disconnect brine draw line from media tank and place the loose end into a fi ve gallon plastic pail fi lled with a solution of hot water and 10 ozs. of resin
mineral cleaner (IRON-X).
2)
Manually advance control timer to BRINE DRAW position (refer to instructions provided with your softener), and allow all hot mineral cleaner solution to
be drawn into mineral bed. Then IMMEDIATELY:
3)
Close main water supply valve or turn power off to pump and proceed with fi lter installation. During time required to install fi lter system, iron-fouled
softener resin will be chemically cleaned.
4)
After fi lter installation is completed, fi nal adjustments made with water turned and the brine draw tube reconnected, manually reposition timer on
softener to BACK-WASH position. Allow timer to perform an automatic complete backwash and regeneration cycle. During backwashing of softener, iron
cleaned from the resin will be washed down drain. It is advisable after chemically cleaning softener to regenerate system twice to fully restore capacity
lost due to iron-fouling.
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 the source.
After completing the installation of the Iron Reduction System, clean the water heater by following these
instructions:
1)
Shut off fuel supply to water heater and close heater inlet water valve.
2)
Drain hot water tank completely. Open inlet water valve allowing heater tank to be refi lled with iron-free water. Continue fl ushing until water runs clear
to drain.
3)
If after approximately 30 minutes fl ushing, water does NOT clear, terminate fl ushing operation. Refi ll water heater with water and pour approximately
1/2 gallon of household bleach into top of heater tank. Allow bleach solution to stand in tank for 20 to 30 minutes. Flush tank again until water is clear
at drain. Turn fuel supply on.
Note: If water does not clear in approximately 10 minutes, water heater probably should be replaced.
Consult owner's handbook and follow manufacturer's instructions.
Prior to commencing installation of the Iron Reduction System, pour 4 to 6 ounces of resin mineral cleaner (IRON-X) or inhibited muriatic acid into fl ush tanks and
bowls and let stand. When installation is completed, fl ush toilets several times with treated water. If iron deposits or stains remain, repeat procedure until clear.
