7.6 Temporary stop
The shutdown of the unit for a few days is considered as temporary.
The unit must be stopped using the display of the control, the external OK signal or via serial if included.
During the temporary stop, the unit must be powered correctly.
When the temporary stop is carried out in this way, all that needs to be done to restart the unit is to set the control to
"ON".
7.7 Stop for long periods of time
When the unit is not used for months this is considered a long period shutdown.
Should the unit be expected to stop for long periods, it is necessary to:
- turn the unit off by means of the control switch;
- disconnect the power supply using the switch / general switch of the unit;
- drain the hydraulic system (unless it uses glycol water);
- empty and clean the condensation drip tray;
- empty the humidifier cylinder if present;
- Check that fresh and exhaust air dampers, if present on the unit, are completely closed.
This case record can in fact be traced back to the storage condition; therefore, refer to the relevant set limits.
Repeat the start-up procedure at the next restart.
Follow the new start-up procedure and replace the cartridge of the leak detection system.
All operations required on the unit for the purpose of maintenance must be carried out by authorised
and qualified staff, as described by Annex HH of IEC 60335-2-40:2018, by local legislations and, with
respect to europen standards, by EN 378-4 and EN 13133.
Before work is started on the unit: check for potentially flammable atmospheres; check for possible
ignition sources.
We reserve the right to make changes without any prior notice.
