BEFORE YOU BEGIN
INSTALLATION, CONFIRM
THE INLET AND OUTLET
OF THE UNIT AND
IDENTIFY THE SERVICE
AND BYPASS POSITIONS
OF THE VALVE (Fig 3).
The
bypass valve is used to isolate the
unit from the plumbing system in
order to perform maintenance or
repairs on the unit. During normal
use the bypass valve should be in
“SERVICE” position and to isolate
it, the valve should be turned to
“BYPASS” position.
Plumbing in your CAFO Iron Filter
Turn the power off to the well pump then shut off the
main water shut off valve which should be located after
the pressure tank. Open a few faucets and empty the
pressure tank before cutting into the line. If your hot
water tank is electric, turn off the power to it to avoid
damage to the element in the tank.
The bypass valve generally comes pre-assembled. If not,
attach the bypass valve to the control valve by pushing it
in and secure it with the metal clips and screws (Fig 4).
Insert Allen key into the bypass handles and make sure
that the valve is in BYPASS position.
Firmly push the inlet/outlet elbow fittings fully into the
open end of the bypass valve and lock them in by inserting
the red locking clips into the slots (Fig 5).
For ease of installation, orient the inlet/outlet fittings in
the direction of the inlet & outlet pipes by simply rotating
them.
Use thread tape on the inlet fitting and attach the INLET
CHECK VALVE on this fitting (Fig 6) with arrow marked on
the check valve pointing towards the bypass valve.
Caution: Do not install the INLET CHECK VALVE on the
outlet fitting as that will cause malfunction of the unit.
Remove the blue locking clip on the brine fitting. Make a
mark on the open white tube of the brine check valve,
about ¾” from the open end. Push the white tube (with
brine valve attached) into the brine fitting until the mark
is flush with the fitting. Replace the blue locking clip.
