Regular checks
Your HRV unit requires minimal maintenance after
commissioning. However, it is recommended that you
check your installation regularly.
If something unusual occurs, messages about the mal-
function, in the form of different alarm texts, appear in
the main product display.
NOTE
Always switch off the power and wait until the
fans have stopped before opening ERS S10.
CLEANING THE VENTILATION DEVICES
The building’s ventilation
devices should be cleaned
regularly with, for example,
a small brush to maintain the
correct ventilation.
The device settings must
not be changed.
NOTE
If you take down more than one ventilation
device for cleaning, do not mix them up.
REPLACING THE AIR FILTER
The filters in ERS S10 are of a type that should not be
cleaned, they have to be replaced instead. These must
be replaced regularly; how often depends e.g. on the
amount of dust in the ventilation air. Test to find out
what is most appropriate for your installation.
Caution
The efficiency of the installation can be reduced
by a dirty air filter.
In the main product’s display, you will receive a reminder
to check the filters. The factory setting for reminders is
every three months.
1.
Switch off the power.
2.
Remove the front hatch by lifting it slightly and then
pulling it towards you.
3.
Pull out the filter cassettes.
4.
Check the condition of the filters andreplace if
needed.
5.
Carry out assembly in reverse order.
Even if the filters look clean, dirt collects in them and
this affects the efficiency of the filters. For this reason,
replace them after approx. 1 years. New filters can be
ordered via a dealer for NIBE.
