air recharge and air bleed-off valves and remove tubing.
Loosen the fitting nut on drain line flow control housing
and remove tubing. Loosen the screw holding the drain

Plug in the electrical cord from the Iron Curtain Control
Center. In approximately four minutes, the aeration
pump will automatically turn on and begin to pump air
into the aeration tank. Allow the Iron Curtain Control
Center to finish the remaining cycles automatically
(approximately 25 minutes). Make certain that the
filter control is in the Service Position (piston all the
way out). Do NOT backwash filter at this time. Set time
of day. Time of regeneration is preset for 12:00 a.m.
Regeneration frequency is preset for every three days.
(Type A Filters are preset for every other day.) If you
wish to reset any of these factory settings, see page 9.

Open the outlet valve on the filter, then open the nearest
cold water faucet and allow the water to run until the air
stops spurting and discoloration is gone. Note: It is
normal for aerated water to appear effervescent.

Regeneration Frequency
Your Iron Curtain Filter System contains a special filter media
mixture which allows it to filter iron longer than standard filters
between backwash regenerations. However, it is our recom-
mendation to leave factory settings as is, unless you wish to
backwash more frequently. You will have to backwash more
frequently if you have iron bacteria, hydrogen sulfide, and/or
manganese present in your water supply. You will also have
to regenerate more frequently if you notice iron bleed through
before the end of the normal service run.

Specifications
When supply water has a pH between 6.0 and 6.9, a Type A
filter system with sacrificial media is generally used. To
insure top performance this media needs to be replenished
periodically depending on water characteristics and usage
patterns, generally every 6 to 18 months. This can be
determined by testing the pH of the water at a cold filtered tap
or by physically measuring the amount of freeboard (See
Figure 8, page 4.) If the pH is 7.0 or greater, media does not
need to be added. If the pH is below 7.0 and/or the amount
of freeboard is greater than 18" for IC-10A or 17" for IC-12A
(see step 5), media needs to be added. If media needs to be
added contact your dealer and ask for the following:
