Timer Operation
A timer controls the air recharge cycle and how frequently it occurs. The timer simultaneously energizes the air pump and the
solenoid valve. After a preset amount of time, the timer shuts off the air pump and de-energizes the solenoid valve.
Solenoid Valve Operation
The solenoid valve is a three-way valve having ports that connect to the air pump, shuttle valve and the atmosphere. In the service
cycle, the solenoid valve is de-energized and closes the port to the air pump, providing a positive shut-off to the pump. This
prevents water from backing up into the air pump and damaging the pump. In the air recharge cycle, the solenoid valve closes the
port to the atmosphere and opens the port from the air pump.
Shuttle Valve Operation
In the service position, water pressure holds the shuttle valve piston in the closed position, trapping the airhead in the aeration tank
and closes the air recharge inlet port and drain port. During air recharge cycle, air pressure is greater than the water pressure and
forces the shuttle valve piston in the open piston. The shuttle valve has an internal pressure relief valve that will relieve pressure
(greater than 100 psi) that may build up in the aeration tank. This precautionary function protects components from failure due to
excessive pressure.
Step 3.
Filter Tank Operation - Backwash Cycle
Reversing the flow of water through the filter bed and backwashing dirty water to the drain cleans the filter bed. Raw water enters
the filter control valve through the inlet port and is directed down the distributor tube and out the lower distributor at the bottom of
the tank, flowing upward through the multimedia filter bed toward the top of the tank into the control valve. Water is then directed
through a specific flow restrictor and out the drain port to be discharged to drain.
Step 4.
Filter Tank Operation - Rinse Cycle
The rinse cycle packs the clean filter bed. Raw water enters the control valve through the inlet port and is directed downward
through the filter bed into the bottom distributor, up the distributor tube into the control valve. Water is then directed through a
specific flow restrictor and out the drain port to be discharged to drain.
Operation Of Aeration Pump
The Iron-Cleer
™
system introduces air into the aeration tank and bleeds off the old head of air automatically. The exchange of
the air into the aeration tank is controlled independently of the recharge frequency of the filter media tank, allowing the air to be
exchanged on a more frequent basis. During an air exchange cycle, the air compressor pumps fresh air into the aeration tank and
the air eliminator solenoid exhausts the old air.
Advantages Over Other Systems
1. No chemicals or salt.
2. No air injectors, venturis, or micronizers.
3. No floats to regulate air volume in aeration tank which “foul” from iron.
4. Two-tank system consisting of a pressurized aeration tank and multi-media depth filter.
5. 110V aeration pump to recharge aeration tank.
6. Can be used on shared wells, municipal water supplies or with buried pressure tanks without additional equipment.
7. Better filtration results.
