Possible Cause / Solution
StartupMaintenance
  1.  Inlet ball valve partially closed or air pressure too low.
    • Completely open air inlet ball valve.
  2. Chemical tube not immersed in container or container empty
    • Immerse tube or replenish.
  3. Hose kinked
    • Straighten the hose.
  4. Ice particles from condensation in air line — Air pump can periodically "freeze up” (stall) due to ice particles in the pump's exhaust (depending on air humidity & other factors)
    • WAIT several seconds to allow the ice particles to melt and blow out, at which time the pump will automatically resume pumping.
  1. Air regulator clogged or failed
    • Clean or replace.
  2. Chemical strainer clogged up
    • Clean or replace.
  3. Vacuum leak in suction line.
    • Tighten the connection(s).
  4. Chemical tube stretched out where tube attaches or pin hole/cut in tube sucking air.
    • Cut off end of tube or replace tube.
  5. Problem with air pump
  6. Use of an oiler in the airline will cause pump to stall
    • Use only clean, dry air.
PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush the chemical out of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical strainer and replace if missing.
