4. OPTIONAL SUBMERGED
EQUIPMENT INSTALLATION
(FIG. 21B)
To complete this installation option you
will need a two way valve not included.
4.1 Install the two way valve on the
inlet pipe to the pump suction.
(before the standpipe if installed)
4.2 Make all other connections before
the two way valve.
4.3 Make tubing connections to the
pump pot or standpipe as in
standard pump above water level
installation.
4.4 Start the pump with the valve fully
open.
4.5 Note the filter pressure. Then
close the valve slightly until the
pressure on the filter drops two or
three psi.
4.6 Go to setting the airflow on page
19
to finish setting airflow. The
slight restriction this creates on
the pump is the same as if it was
set at approximately one foot
above water level and allows the
pump to draw air in at the pump
pot or standpipe.
(Fig. 21B)
5. Lay the 3/8 tubing along desired
route to the compression fitting on the
combination needle valve flow meter
on the Clear O3® unit.
6. Connect the tubing to the compression
fitting. (Fig. 22)
7. Use the provided wires ties to tie
the loose tubing to the conduit or
plumbing. (Fig. 23)
