7.6 Temporary stop
The stopping of the unit for a few hours in the day "during non-working hours" or for a few days "over the weekend" is con-
sidered 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 circulation pump is managed by the control of the unit, if the temporary stop takes place within sub-zero air tem-
perature and the system does not have glycol fluid, make sure water circulation is guaranteed and that no taps or valves
are preventing it.
If, in the previous conditions, the circulation pump is not managed by the control, the pump must always be kept running.
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
If the unit is to remain stopped for a season or for long periods of time, 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 contains glycol water).
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.
If the hydraulic system is discharged during a stop of the unit, turn off the power to prevent the pump from
starting, in antifreeze function, without water being present.
