5. Remove the old pump tube from the pump body. If the roller assembly comes out with the tub-
ing, 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 cap-
ture the tubing within the body and not pinch it between the
halves. Do not use any tool other than your finger tips to ma-
nipulate the tubing into the housing or you may damage the tube.
8. While holding the pump halves together with your hand, re-
insert 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 tub-
ing ends and secure them using the new hose clamps sup-
plied in the kit. Be sure to use pliers to squeeze and tighten
the hose clamps.
