Service and Maintenance
The need for service and maintenance strongly depends on the environment in which the machine is
used as well as the usage profile, how often and how much it is used. The most obvious example of
this is the filters which can deteriorate very quickly when the machine is used in dirty environment.
For this reason, the A15ES can be delivered with filter monitoring functions that triggers alarms of
the filters need replacing or if, in some situation and by mistake, no filter is present.
The service and maintenance work is to be carried out by authorised and qualified personnel
adhering to a calendar based maintenance schedule and to support it, the machine itself shows a
service reminder at every such even provided the service schedule is followed and the service alarm
is reset after each performed service. In the schedule, approximate equivalent and corresponding
operation hours has been added for reference only.
Every 6 months (4750 hours):
1. Inspection of, and if required replacement, of filters
2. Control of function
3. Zeroing of differential pressure sensors.
Every 12 months (9500 hours):
1. Inspection of, and if required replacement, of filters
2. Inspection and cleaning of machine interior including rotor
3. Control of function including check of air flows
4. Test of RCD. (Requires the machine to be powered whilst the electronics cabinet is
open and thus it must be performed by personnel with required competence.)
Every 60 months:
In addition to the yearly, 12 months service above, the following tasks are added:
1. Check of power consumption with the regeneration heaters
2. Replacing the overheat protection
3. Check of capacity
If the cost and consequence of interruptions in machine operation warrants it,
preventive replacement of:
4. Rotor motor
5. Fans
The machine is designed to safely manage failure with the rotor motor and/or the fans and therefore
preventive replacements of these are not mandatory.
