Replacing Pump Tubing:
1. Remove pump platform (refer to the Removing Pump Platform(s)
procedure located earlier in this section).
2. Remove the two white plastic hose clamps from the pump tube
connections (see Fig. 1&2). Remove the concentrate delivery
tubes from the hose ends.
3. Loosen and remove the four thumb screws from the pump body.
4. Remove the rear pump body half only to reveal the pump tube
and rollers.
5. Remove the old pump tube from the pump body. If the roller
assembly comes out with the tubing, place it back into the pump
housing being sure to align the roller assembly shaft keyway to
the motor shaft so that the two interlock.
6. Firmly press the new hose into the pump body around the roller
assembly, being sure to keep the protruding ends even with each
other.
7. Once the tubing is in place, hold the tubing with one hand, capture
the lower part of the tubing with the outer housing, then proceed to
capture the shaft of the roller assembly and push the rear pump
housing into place. Make sure to capture the tubing within the
body and not pinch it between the halves. Do not use any tool
other than your finger tips to manipulate the tubing into the housing or you may damage the tube.
8. While holding the pump halves together with your hand, reinsert
the four thumb screws and tighten using a criss-cross pattern as
shown. The thumb screws should be tightened about 1/4 turn
beyond snug.
9. Insert the two concentrate delivery tubes into the pump tubing
ends and secure them using the new hose clamps supplied in the
kit. Be sure to use pliers to squeeze and tighten the hose clamps.
