Maintenance

• The hydro pneumatic equipment does not require
maintenance only if taking the following caution measures:
• When there is risk of freezing empty the pump
completely removing the drain cap (B). Remember to
purge the pump before starting it back.
• Check periodically the foot valve (not included) and
clean if necessary.
• When the hydro pneumatic equipment will be used long
periods of time, we recommend emptying the pump fully
and rinse with clean water.
