7.O2 Squeeze Tube Replacement
Replace the pump squeeze tubes at regular maintenance intervals to avoid the negative impacts of tube wear. These include,
chemical delivery volume decline or in extreme cases, tube rupture. If the tube does rupture, clean all product from the pump
with a damp cloth.
1) Remove the main cabinet cover.
2) Loosen the pump front captive screw and remove the pump front cover.
3) Remove the old tube with the compression-style fittings.
4) Install the new tube, oriented with flat sides facing towards the front.
5) Do not lubricate the squeeze tube or spinner roller. Maximum delivery volume and accuracy requires clean, dry surfaces.
6) Insert new tube from left side of pump, with pump spinner oriented between an 11 to 1 o’clock position.
7) Slowly turn the spinner clockwise, using your hand as you position the tube into place, midway on the roller. The tube must
also be evenly distributed on either side of the spinner.
WARNING: Before you change squeeze tubes, disconnect the incoming power source!
