Diaphragm module replacement is recommended for every 24 months of continuous operation or after 20,000 hours of use.

If the pump makes an abnormal noise or if the discharged air volume and pressure is extremely low, turn off the air pump

immediately. This may indicate a worn or damaged diaphragm, which needs to be replaced. Diaphragm Replacement Kit

(Part No.: DRK615) can be ordered from Alita Industries or from your local Alita representative.
