Changing or Installing 5/8” Silicon Tubing

To install or replace the tubing, disconnect the pump from its power supply, then undo the four thumbscrews on the drive head (black plastic end). Remove the drive head cover.

Manually rotate the pump impeller in any direction while gently pulling on the tubing to pull it away from the body.

Remove tube clamps from the old tubing.

Position the new 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.

Replace clamps onto the tubing close to the drive head to prevent the tubing from being pulled into the drive head.

Reposition the pump head cover and screw firmly in place, but only finger tight. Do not use a wrench or over tighten.
