4.3 How To Install the Tubing and Fittings
4.3.1 Inlet Tubing - Locate the inlet fitting of the pump head, see fig 4.6. Remove the
tube nut. Push the clear PVC suction tubing onto the compression barb of the
fitting. Use the tube nut to secure the tube. Hand tighten only.
4.3.2 Footvalve/Strainer -Trim the inlet end of the suction tubing so that the strainer
will rest in a vertical position, approximately one inch from the bottom of the
solution tank. This will prevent sediment from clogging the strainer. Loss of
prime may occur if the footvalve is permitted to lay on the bottom of the solution
tank in a horizontal position. Slip the ceramic weight over the end of the suction
tube. Press the footvalve/strainer into the end of the tube. Secure the ceramic
weight to the strainer. Drop the strainer into the solution tank.
4.3.3 Outlet Tubing - Locate the outlet fitting of the pump head, see fig 4.6. 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.
Trim the other end of the outlet tube leaving only enough slack to connect it to the
Injection/Check valve Fitting (see below). Increasing the length of the outlet tube
increases the back pressure at the pump head, particularly when pumping viscous
fluids.
Keep the inlet and outlet tubes as short as possible.
