Niro Soavi S.p.A
3.3.3 START-UP
WARNING: The lubrication oil indicated in the specifications is suitable
for operating temperatures between +5°C ed i +40°C: DO NOT START the
machine if ambient temperature is lower than +5°C to avoid damage to the
lubrication system.
Check with NIRO-SOAVI Customer Service for the type of lubricant
suitable for the specific local conditions.
ATTENTION: If ambient temperature is lower than +5°C, do not start the
machine before checking the conditions of the plunger water lubrication
system and any water heat exchanger.
Once all preliminary checks have been completed, the machine can be started
following the procedure below.
• Open all on/off valves on utility lines (water, air, steam) and regulate the flow
rates if necessary.
ATTENTION: The machine must NEVER be started without water for
plunger lubrication, otherwise serious damage could be caused to the
seal packings and plungers; with ceramic plungers, this incorrect
procedure may cause plungers failure because of thermal shock. For
further details on thermal shock problems with ceramic plungers see
Section 4 - MAINTENANCE.
WARNING: An excess of cooling water can lead to flooding of the sump or
excessive water splashing on guiding pistons, with the risk of water going
into the drive section. It is therefore important to check the water flow and
adjust it to approximately 60÷100 l/h per piston. The lubrication circuit
should be regularly drained to drain out any water that might have gone
inside the oil.
• Feed the machine with product at the required flow rate and pressures as
indicated in Section 1 – TECHNICAL SPECIFICATIONS.
WARNING: Feeding pressures lower than the limits given will cause
CAVITATION in the machine, recognized by the typical noise produced by
the head, which will seriously damage the whole machine. NIRO SOAVI
shall not be libale for breakages, malfunctions or damage to the machine
caused by CAVITATION even if this occurs during the 12 month guarantee
period.
