Maintenance
Preventive Maintenance
Schedule
Establish a preventive maintenance schedule, based on the pump’s repair history.
Mix Manifold
See mix manifold manual 310654.
Maintenance
Pump Test/Meter Calibration
See ProMix Easy Operation manual. If pumps/meters fail test, see Troubleshooting, page 10.
Wet Cup
Check pump and dispense valve
Dispense Valve | Storage |
|
See dispense valve manual 310655.
Before storing the pump, always flush it, see ProMix Easy Operation manual. Relieve the pressure, page 7.
Pump
See applicable pump manual 310671, 310672, or 310662.
Turbine Alternator
Replace bearings every 2000 hours. See page 19.
Icing
If you experience icing at the pump air manifold:
•Reduce pump input air pressure below 80 psi (0.56 MPa, 5.6 bar), if required spray pressure allows.
•Reduce moisture in compressed air supply, or use heated air.
Air Filters
If icing persists, see table below.
Check daily. Drain and clean as necessary. See page 15.
