! Strainer - Trim the inlet end of the suction tubing so that
the strainer will rest approximately two inches from the
bottom of the solution tank. This will prevent sediment
from clogging the strainer. Slip the ceramic weight over the
end of the suction tube. Press the strainer into the end of
the tube. Secure the ceramic weight to the strainer. Drop
the strainer into the solution tank.
! Outlet Tubing - Locate the outlet fitting of the Pump
Tube. Remove the tube nut. Push the opaque outlet
(discharge) tubing onto the compression barb of the fitting.
Use the tube nut to secure the tube. Hand tighten only.
Keep outlet tube as short as possible.
! Injection/Check Valve Fitting Installation - The
Injection/Check valve fitting is designed to install directly
into either 1/4” or 1/2” female pipe threads. This fitting will
require periodic cleaning, especially when injecting fluids
that calcify such as sodium hypochlorite. See section 7.0.
Install the Injection/Check valve directly into the piping
system. To prevent trapped gasses, install the fitting in an
upward direction. Use Teflon thread sealing tape on the pipe
threads.
Push the opaque outlet (discharge) tubing onto the compres-
sion barb of the Injection/Check valve fitting. Use the tube
nut to secure the tube. Hand tighten only.
