9 MAINTENANCE
9.1 Maintenance instructions
OBLIGATION:
Both regular and extraordinary maintenance activities must be carried out by AUTHORISED
TRAINED INDIVIDUALS equipped with all the necessary personal protective equipment.
The machine site of installation must meet all the safety requirements.
The procedures set by the Manufacturer must be followed.
Before any kind of maintenance is carried out the following measures must be observed:
•
isolate the machine from the mains using the yellow/red disconnector on the machine electrical panel;
•
place a sign saying, "Do not operate - maintenance in progress" on the disconnecting switch open;
•
use appropriate personal protective equipment (for example: helmet, insulating gloves, protective goggles, safety
shoes, etc.);
•
use tools that are in good condition and be sure to be familiar with the instructions before putting them into practice.
Whenever measurements must be taken or checks performed with the machine running, it is necessary to:
•
• make sure that any remote control systems are disconnected. Keep in mind, however, that the PLC on board of the
main machine controls their functions and can activate and deactivate the components, creating dangerous situations
(such as for example powering fans and their mechanical drive systems);
•
work on the open electrical panel for as short a time as possible;
•
close the electrical panel as soon as the single measurement or check has been performed.
Furthermore, the following precautions must always be taken:
•
during venting operations, protect against possible fluid leaks at dangerous temperatures and / or pressures;
•
when replacing electronic boards, always use suitable equipment (extractor, antistatic bracelet, etc.);
•
if replacing a fan or other heavy component, make sure that the lifting equipment is suitable for the weight;
•
do not access the fan compartment without first isolating the machine using the main switch on the panel and
displaying a "Maintenance - do not switch on" sign;
•
always use only original spare parts purchased directly from the Manufacturer or from official dealers;
•
before closing and restarting the machine, make sure to remove all tools or foreign bodies.
The list of scheduled maintenance operations is shown in the next paragraph of this manual.
For each intervention, both of ordinary and extraordinary maintenance, a special form must be issued and kept by the user.
If a Scheduled Ordinary Maintenance notebook is available on the machine, all the operations carried out must also be recorded
on the same.
9.2 Scheduled maintenance
Carry out all the scheduled maintenance activities at the indicated intervals.
INFORMATION:
Failure to carry out regular maintenance will make the warranty null and void and relieve the
manufacturer of all safety related responsibilities.
The scheduled maintenance activity intervals are indicated in the tables on the following pages.
