Xylem C-1500N DIAPHRAGM PUMPS - Manual (Page 6)

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.

4.3.4 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.
Install the Injection/Check valve directly into the tee fitting. Do not install the fitting into a pipe stud
and then into the tee. The solution must inject directly into the flow stream.
Use Teflon thread sealing tape on the pipe threads. Push the opaque outlet (discharge) tubing onto the
compression barb of the Injection/Check valve fitting. Use the tube nut to secure the tube. Hand tighten
only.
Injection/Check valve fitting fitting will require periodic cleaning, especially when injecting fluids that
calcify such as sodium hypochlorite. These lime deposits and other build ups can clog the fitting
increasing the back pressure and interfering with the check valve operation. See section 6.0.
