5.4 How To Install the Tubing and Fittings
! Inlet Tubing - Locate the inlet fitting of the pump head. Remove the tube
nut. Push the clear suction tubing through the tube nut and onto the fitting
barb. Hand tighten the tube nut to secure the tubing.
CAUTION: Proper eye and skin protection must be
worn when installing and servicing the pump.

worn when installing and servicing the pump.
! Footvalve/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’s barbed fitting into the end of
the tube. Secure the ceramic weight to
the strainer. Drop the strainer into the
solution tank.
! 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 through the tube nut and onto the
compression barb of the Injection/Check
valve fitting. Hand tighten the tube nut
to secure the tubing.
