Winterizing Iron Curtain Systems (Optional)
In certain climates where houses and/or cottages are not
heated during the winter months, Iron Curtain Systems must
have the water removed from them to protect from damage
due to freezing. Following are instructions for "winterizing"
Iron Curtain Systems.
Draining of the Iron Curtain System should be done in con-
junction with or after the complete water distribution system
is drained to prevent water from entering the Iron Curtain
System after it has been winterized. After Iron Curtain Sys-
tem and water distribution system are drained, make sure
all water shut-off valves are open.
Instructions for winterizing Iron Curtain Systems:
1. Before shutting off the water, manually shift the filter
control valve to the backwash cycle.
2. Unplug the electrical cords for the Aeration Control Center
and the Filter Control Valve.
3. Let unit backwash for 15 minutes.
4. Place the Aeration Tank Bypass in shut off mode - See
page 11. (Make sure you leave the filter tank bypass
in the service position.)
5. Plug the electrical cord for the Filter Control Valve
back in and manually shift the control valve to the fast
rinse cycle.
6. Unplug the filter electrical cord.

Problem
A. Did not plug in aeration pump prior
to filling
B. Shuttle valve stuck in the open
position.
A. Corrosive water condition in cop-
per distribution piping system
Cause
1. Drain port open
1. Shuttle valve fouled with foreign
material.
2. Excessive pressure from water sup-
ply system causing internal pressure
relief valve to open.
3. Solenoid vent port fouled with for-
eign material or faulty solenoid.
4. Seat on end of piston assembly
dislodged or damaged by foreign
material
5. Vent port connected to bleed off
drain line or filter
6. Faulty timer stuck in the ON position
7. Bleed off tube in aeration tank
restricted.
8. Air pump failed during air recharge
cycle.
1. Low pH condition of the raw water
supply. On type "A" filters, the pH
correction media may be depleted
2. In rare occasions, highly aer-
ated water in combination with a
specific water supply can create a
slightly corrosive condition
3. Shorten bleed off tube, reduce
recharge frequency
1. Time setting tolarances are ±5% and may result in pump starting by as much
as 72 minutes difference each day and still be within specifications. This does
not affect the performance of the Iron Curtain.
7. You will need to plug the fitting for the 3/8" drain connec-
tion on aeration head. 3/8" plug available from manufac-
turer - p/n 100681.
A. Consult your dealer if assistance is needed with this
step.
8. Plug in the electrical cord for the Aeration Control Center.
A. This will start the Air Recharge Cycle.
B. Water/air will drain out the filter drain pipe.
C. You need to leave in this cycle until only air is
discharging out of the drain pipe.
D. You will need to repeat this step if the air pump
shuts off while water is still discharging to the drain.
9. To start pump, unplug the electrical cord for the Aeration
Control Center, re-plug in.
10. Turn off water when only air is discharging to drain.
11. Remove the plug installed in the pressure relief valve previ-
ously installed.
12. Loosen the union nuts on the Aeration Tank Bypass Valve
on the Aeration Head. (Make sure you loosen the nuts
between the bypass and the aeration head.)
13. Move the Aeration Tank to the side.
14. You then can proceed with winterizing the rest of the build-
ing.
15. You will need to make sure there is no water left below the
1" Check Valve. (Consult dealer if you have questions.)
16. Make sure the Aeration Tank Bypass Valve is in the service
position.
17. System is now winterized.
18. When turning the system back on, refer to the start up
instructions on page 5.
Solution
1a. Plug in aeration pump. (See start-up
instructions - page 5.)
1b. Clean or replace shuttle valve and
piston assembly
2b. Reduce water supply pressure
3b. Clean or replace solenoid assembly
4b. Clean or replace piston assembly
5b. Vent port MUST vent to an atmospheric
drain site.
6b. Replace timer
7b. Remove aeration head and clean or
replace bleed off tube.
8b. Replace/Repair pump
1a. On type "A" filters add pH correction
media to filter tank, see Installation
and Operation manual
2a. Install a polyphosphate cartridge filter
after the Iron Curtain Filter System to
protect the distribution piping
3a. See page 9 for recharge frequency
changes. Shorten bleed-off tube
to 9" (Page 8)
