GENERAL NOTES
• Comply with the inspection and ordinary maintenance intervals so as to ensure suitable working
conditions and explosion-proof protection.
• Before carrying out any maintenance operation or repair on the internal parts, discharge completely
air and fluid pressure inside the pump set.
• After the maintenance intervention, make sure that all the safety measures are completely and cor-
rectly restored.
• Once the maintenance operations/repairs have come to an end, clean the whole unit.
• Use only original spare parts for repairs.
A suitable maintenance is important for a longer duration of the equipment in good working condi-
tions and efficiency ensuring functional safety as time goes by.
All maintenance operations must be carried out by a qualified staff. The pump design and the mate-
rials used to manufacture it limit the maintenance interventions to a simple periodic cleaning.
The staff must be provided with the individual protections that are generally used for similar opera-
tions. They also must follow the safety rules described in section 7.2.
