SPECIAL INSTRUCTIONS FOR SPLIT-STREAM AND
PUBLIC WATER SUPPLY TYPE INSTALLATIONS:
For split-stream type installations, a secondary pressure tank must be installed as in Figure 1. On public water supply type installations, a pressure tank
must be installed as in Figure 1.
The pressure tank should be of same capacity as would normally be installed if water system were a standard private well type. Also note both applica-
tions require a normally-closed solenoid valve. Follow standard installation procedures above with following additions and modifi cations.
1) Install pressure tank (See Figure 1) or secondary pressure tank (See Figure 1) as indicated by appropriate diagram.
2) Install normally-closed solenoid valve, 110/120V, 60Hz after water meter on public water supply installations or after a line split for untreated
water on split stream installations.
3) On both types installation, install hyrdo-charger between pressure tank (secondary pressure tank on split-stream type installation) and normally-
closed solenoid valve.
4)
Install pressure switch after hydro-charger and wire it to solenoid valve (secondary pressure switch on split-stream). Set high pressure on pressure
switch (which controls opening and closing of 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 secondary pressure switch 20/38 psi.
For public water supply type 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 fi gure.
IMPORTANT NOTE
IMPORTANT NOTE
Failure to set pressure switch as described above will not allow proper closing of solenoid valve during periods of low system pressure. Improper
function of solenoid valve will cause total failure of system.
