8.0 PERIODIC MAINTENANCE
8.1 Cleaning and storage of the pump
Do not let your fluid dry in the pump or in the hoses. It may harm the pump. Clean the pump regularly
by pumping a suitable solvent for your fluid until the pump is cleaned. Make sure the fluids you are
using are compatible with your diaphragm material. If you are not going to use the pump for a long
period, clean the pump and relieve the pressure.
8.2 Tightening the screw connections
Inspect damage to the hoses before every use and change if necessary. Check all the screw
connections for tightness and seals against leak. Check the screw connections in every two months
and re-tighten with proper torque. First tighten the fluid cover screws than the manifold screws.
Tighten the screws applying the proper torque from the torque chart. (Fig. 6)
