An RPI document.

• DO NOT lubricate or apply grease to any of the pump and motor parts; they are permanently lubricated.
• The pump gasket and air filters should be checked if the performance of the pump provides low vacuum. These should be replaced at least annually.
• The Bacteria Filter RPI Part #’s GOF024 & GOF025 should be changed if a reduction of vacuum is noticed or after one month of pump service; whichever comes first. Also, it MUST be replaced if fluids have entered the filter; this could easily be identified by the discoloration of the filter material.
• Always remember to check for loose, cracked or poor tubing connections if there is no vacuum or insufficient vacuum.
• Inspect the integrity of the power cord and verify proper polarity and ground.
