It is advisable to then close the pump nozzles (e.g. with plastic caps).
3. Oil or grease all exposed machined parts and surfaces of the pump (with
silicone-free oil or grease, food-approved if required) to protect them against
corrosion.
Observe the additional instructions on preservation.
If the pump set is to be stored temporarily, only preserve the wetted components
made of low-alloy materials. Commercially available preservatives (food-approved, if
required) can be used for this purpose. Observe the manufacturer's instructions for
application/removal.
Observe any additional instructions and information provided. (ðSection3,Page10)
