For a split-stream installation, a secondary pressure tank must be installed as shown in the split-stream installation diagram (Page
10). On a public water supply installation, a pressure tank must be installed as shown in the public water supply installation
diagram (Page 10). It is recommended in both applications to use a standard air-to-water pressure tank with an air relief valve of a
capacity that would normally be installed if the water system were a standard private well. Also note that in both applications a
normally closed solenoid valve is required. Follow the standard installation instructions above with the following additions and
modifications:
See Diagram page 10
1. Install the pressure tank as indicated by the appropriate diagram.
2. Install a normally closed solenoid valve after the water meter and after a line split for untreated water (if there is one).
3. On both types of installation, install the Air injector between the pressure tank (secondary pressure tank on split stream
installations) and normally closed solenoid valve.
4. Install the pressure switch after the Air injector and wire it to the solenoid valve (secondary pressure switch on split-stream
installations). Set high pressure on pressure switch (which controls opening and closing of the solenoid valve) 2 to 3 psi lower
than low pressure on primary pressure switch. EXAMPLE: If primary pressure switch is set at 40-60 psi, set the secondary
pressure switch at 18 to 38 psi.
5. For public water supply installations, contact your local water department or plant operator and ask what the normal low
system pressure is. Set high pressure on pressure switch 2 to 3 psi lower than this figure. NOTE: Failure to set the pressure
switch as described above will not allow proper closing of the solenoid valve during periods of low system pressure.
Start-Up Instructions
1. Plug the valve into an approved power source.
2. When power is supplied to the control, the screen may display "INITIALIZING WAIT PLEASE" while it finds the service position.
3. If the system has been inactive, you may have to hold and press ' ' until you hear a beep to unlock the display screen. Press
"
" and hold for 3 seconds to initiate a manual regeneration and advance the valve to the Backwash position. Open the
inlet on the bypass valve slowly and allow water to enter the unit. Allow all air to escape from the unit before turning the
water on fully then allow water to run to drain for 3-4 minutes or until all media fines are washed out of the unit.
5. Press any button to advance to the RINSE position. Check the drain line flow. Allow the water to run for 3-4 minutes or until
the water is clear.
6. Press any button to advance to the SERVICE position. Open the outlet valve to the bypass, then open the nearest treated
water faucet and allow the water to run until clear, close the tap and replace the faucet screen.
7. By cycling the system adjust the air charger bypass to draw air for one third of the cycle time of the pump or pressure system
or for a minimum of 20 seconds whichever is greater.
8. Be sure air vent is installed at the highest point on the inlet to the filter if necessary put in a tee and raise it up so that it is
higher than the head of the filter, before operating system ensure it is in the open position and the cap has been removed.
**NOTE** - during normal operation it is not uncommon for the air vent to sputter some water, if it begins to drip
continuously shut it off and clean with a mild acid solution such as pro res-care or vinegar and reassemble.
Plumbing System Clean-Up
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 procedure.
