An HRV unit is a ventilation heat exchanger that utilises
the heat in the building’s ventilation air to heat the in-
coming outdoor air. From the outgoing ventilation air
(1), heating energy is recovered from the dwelling and
transported to the HRV unit. In the heat exchanger (2),
the heat from the indoor air is transferred to the incom-
ing outdoor air.
Ventilation air
The hot air is transferred from the rooms to the HRV unit via the
building’s ventilation system using a fan.
A
In the HRV unit, the air releases heat energy and the temperature
drops significantly. The cold air is then blown out of the building.
B
Outdoor air
The outdoor air is transferred to the HRV unit via the building’s
ventilation system.
C
In the HRV unit, the air absorbs the heat energy and the temper-
ature is raised.
D
A fan blows the heated air into those rooms that have supply air
inlets.
E
The temperatures are only examples and may vary between different installations and time of year.

2 Function of the HRV unit

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.

3 Maintenance of ERS S10

CHECK THE WATER LOCK FOR
CONDENSATION WATER
The water seal must be checked at least once a year,
ideally in the autumn.
The water seal is located outside ERS S10. Contact your
installer if you are unsure of where to find it.
No condensation water is generated in the HRV unit
during the warm period of the year and the water seal
will dry out.
During the colder parts of the year, ERS S10 can produce
several litres of condensation water every day. If the
condensation outlet is not working, this may cause water
damage inside the home.
The water seal must not dry out during this part of the
year, because air will be drawn into the HRV unit due
to the negative pressure in the unit, which will then
prevent the condensation water from running out.
1. Check that the condensation drain and the water
seal are not clogged with dirt.
2. Pour approx. one litre of water into the water seal.
3. Check that the water runs through unobstructed.
CLEANING THE HEAT EXCHANGER
Check the heat exchanger every other year and clean if
necessary. Avoid contact with the fins.
Caution
Do not damage the fins. If you are unsure,
contact your installer for help with cleaning.
1. Remove the heat exchanger by pressing gently from
the rear.
2. Clean the heat exchanger carefully, e.g. with a vacu-
um cleaner. If necessary, you can use warm water
and mild soap.

NIBE ERS S10-400Chapter 3 | Maintenance of ERS S108

In most cases, the main product notes a malfunction (a
malfunction can lead to disturbance in comfort) and in-
dicates this with alarms and shows action instructions
in the display.
Troubleshooting
If the operational interference is not shown in the display
the following tips can be used:
BASIC ACTIONS
Start by checking the following items:
• That the main product is running and that the supply
cable to ERS S10 is connected.
• Group and main fuses of the accommodation.
• The property's earth circuit breaker.
LOW OR A LACK OF VENTILATION
• Filters blocked.
– Replace the filters.
• The ventilation is not adjusted.
– Order ventilation adjustment.
•Closed, too much choke or blocked ventilation device.
– Check and clean ventilation valves (see page 7).
• Fan speed in reduced mode.
– Enter the main product’s menu 1.2.1 and select
"normal".
• External switch for changing the fan speed activated.
– Check any external switches.
• Fan running slow because of low incoming outdoor
air temperature.
– Contact the installer in the event of recurring prob-
lems.
HIGH OR DISTRACTING VENTILATION
• Filters blocked.
– Replace the filters.
• The ventilation is not adjusted.
– Order ventilation adjustment.
•Closed, too much choke or blocked ventilation device.
– Check and clean ventilation valves (see page 7).
• Fan speed in forced mode.
– Enter the main product's menu 1.2.1 and select
"normal".
• External switch for changing the fan speed activated.
– Check any external switches.
• Silencers not correctly installed.
– Contact your installer!
