spare parts.
We recommend keeping track of the intervenons carried out on the unit so as to make any troubleshoong easier.
In case of failure or malfunconing:
• check the type of alarm triggered to report it to the assistance centre;
• contact an authorised assistance centre;
• if requested by the assistance centre, immediately deacvate the unit without reseng the alarm;
• request that original spare parts be used.
SHUTDOWNS FOR LONG PERIODS
The shutdown mode of the plant depends on the site of applicaon and the me the plant is expected to be shut down. If the unit is equipped
with the anfreeze system, even when o (system on unit at “o” posion).
