(Figure #7).
9. Slide the pump head onto the motor drive shaft and turn it clockwise to lock onto the 2 (two) locking collars.
10. Push the suction tubing and discharge tubing into the pump head tubing (Figures 5 and 11). Do not push
tubing past retaining collars. Install a hose clamp to hold the tubing together. Use pliers to squeeze the
clamp tightly.
: Hose clamps must be tightened securely to prevent leakage, except when using
.13in.-I.D. Norpreen tubing with barb fittings (no clamps).
