new pieces of foam tape.
12. Use the Phillips screws to connect the pump head to the
new motor assembly.
13. Attach the black and red wires to the new motor assembly
(black wire to the black negative terminal, and red wire to
the red positive terminal on the motor assembly).
14. Align the tabs on the motor brace with the grooves in the
pump housing and insert the new motor assembly into the
pump housing.
15. Secure the pump head to the pump housing with the four
tapping screws.
16. Plug the 4-pin connector back into the control board.
17. Slide the control board back into the pump housing using
the slots in the sides of the housing.
18. Carefully push all wires into the housing and screw the end
plate back on the pump housing.
19. Rotate the shaft of the motor so the screw hole in the shaft
is vertically facing. Slide the head roller onto the motor
shaft, centre it, and secure it using the screw, washer,
and nut. Make sure the head roller turns freely and is not
touching the pump head.
20. Position the tubing around the impeller in a “U” shape with
equal lengths. Turn the impeller to the 6 and 12 o’clock
position and push the right hand tubing into the tubing
pathway, holding near the bottom. Rotate the impeller
clockwise until tubing is in place. Push the left half of the
tubing into place and rotate the impeller.
21. Position the pump head cover and screw it firmly in place
by hand. Thumbscrews should be finger tight. Do not use a
wrench or over-tighten.
