bypass and close the shut-off valve to the water heater.
5. Drain down the plumbing system.

Mount the control valve and aeration pump on the filter tank.
7. Do all necessary plumbing as shown in Figures 1, 2 & 3
on page 8. If you want to filter outside hosebibbs, be sure
the filter system is properly sized to handle the flow rates
required for extended periods of time, in addition to the
normal household demand. Use a PVC compatible thread
sealer when connecting fittings to the aeration tank
manifold. Care must be taken not to overtighten
fittings into aeration tank manifold.

Run the drain line from the filter control in accordance with
local plumbing codes. The drain line will emit surges of
excess air from the aeration tank and therefore must be
secured. Models IC-10 & IC-10A have a 1/2” Male NPT
Drain Connection. Models IC-12 & IC-12A have a 3/4”
Female NPT Drain Connection. For all models, use a
minimum 3/4” I.D. Drain Line.

Connect the 3/8" white polytubing from the white fitting on the
aeration tank manifold to the air recharge valve on the Iron
Curtain Control Center. Connect the 3/8" black polytubing
from the black fitting on the aeration tank manifold to the air
bleedoff valve on the Iron Curtain Control Center. The 3/8"
white and black tubing are located in the Control Center
box. Cut tubing off to minimal necessary length after
aeration tank and filter tank are in place. Secure tubing
to the plumbing with cable ties provided. Connect drain
discharge line to pressure relief valve.

Electrical Requirements for Filter Control: A continuous
110 volts is required to cycle the controls and aeration pump.
Make certain the electrical supply is always on and cannot be
turned off with another switch.

Existing Plumbing: The condition of the existing plumbing
should be free from lime and iron build-up. Piping that is
heavily built-up with lime and/or iron should be replaced.

Equipment Location: See Figures 1, 2 & 3 on page 8&9.
Location of Aeration and Filter Tank: See Figures 1, 2 &
3 on page 8&9. These two tanks should be installed after the
pressure tank and as close to each other as practical. If you
want to filter outside hosebibbs, be sure the filter system is
properly sized to handle the flow rates required for extended
periods of time, in addition to the normal household demand.

Drain Lines: All drain lines must be a minimum of 3/4" or
equal to the size of the drain line connection at the control
valve or larger. Avoid overhead drain lines when possible. If
used, overhead drain lines are not to exceed a height of five
feet above the control valve and should be no more than fifty
feet in length.

Pressure Relief Valve: A pressure relief valve is installed in
the aeration tank manifold and it is recommended that a
separate drain line be extended toward the floor or to a drain
recepticle. NOTE: Do not plumb to a common drain line with
filter backwash discharge.

separate drain line be extended toward the floor or to a drain
recepticle. NOTE: Do not plumb to a common drain line with

Check Valve: On applications where there is a non-filtered
demand for water such as joint wells (where the filter system
is only installed in one of two or more homes), outside
hosebibbs, farms with outbuildings, yard hydrants, etc. a
spring loaded check valve is provided and must be installed
ahead of the aeration tank. See Figures 1, 2 & 3 on page 8&9.
It is recommended to install the check valve in a vertical
upflow position with a minimum 12" water column above the
check valve. This prevents air from escaping past the check
valve. If the check valve is installed in a horizontal position, and
there is a simultaneous demand for both non-filtered and
filtered water, the air head in the aeration tank may escape
backwards past the check valve into the non-filtered water line
and cause air spitting.

Filtered Water: Normally, filtered water is furnished to all
household lines; however, outside faucets are typically left
on raw water. If filtered water is provided to outside faucets,
the filter system must be sized accordingly.
