The temperatures are only examples and may vary between
different installations and time of year.
An HRV unit is a ventilation heat exchanger that utilises the
heat in the house’s ventilation air to heat the incoming out-
door air. From the outgoing ventilation air (1), heating energy
is recovered from the dwelling and transferred to the HRV
unit. In the heat exchanger (2), the heat from the indoor air
is transferred to the incoming 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 temper-
ature 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 build-
ing’s ventilation system.
C
In the HRV unit, the air absorbs the heat energy and the
temperature is raised.
D
A fan blows the heated air into those rooms that have supply
air inlets.

Regular checks
Your HRV unit requires minimal maintenance after commis-
sioning. However, it is recommended that you check your
installation regularly.
If something unusual occurs, messages about the malfunc-
tion, 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 30.
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 30 are of a type that should not be cleaned;
they have to be replaced instead. These must be replaced
regularly, although how often depends of factors such as
the amount of particles 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 the reminder is
every three months, although the countdown begins again
if the power to the main product is interrupted.
1. Switch off the main product.
2. Remove the filters.
3. Check the condition of the filters andreplace if needed.
4. 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.

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 30. Contact your in-
staller 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 30 can produce
several litres of condensation water every day. If the con-
densation outlet is not working, this may cause water dam-
age 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 neg-
ative pressure in the unit, which will then prevent the con-
densation 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 ne-
cessary. 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 undoing the screws
holding it in place.
2. Clean the heat exchanger carefully, e.g. with a vacuum
cleaner. If necessary, you can use warm water and mild
soap.

NIBE ERS 30Chapter 3 | Maintenance of ERS 308

In most cases, the main product notes a malfunction (a
malfunction can lead to disturbance in comfort) and indic-
ates 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 30 is connected.
•Group and main fuses of the accommodation.
•The property's earth circuit breaker.
LOW OR A LACK OF VENTILATION
•Level monitor tripped.
–Checking the condensation water drain and water seal.
•The exhaust air filter and/or the supply air filter is clogged.
–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.
–S-series: Enter the main product’s menu 1.2.1 and select
"Normal".
F-series: Enter the main product’s menu 1.2 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 problems.
HIGH OR DISTRACTING VENTILATION
•The exhaust air filter and/or the supply air filter is clogged.
–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.
–S-series: Enter the main product’s menu 1.2.1 and select
"Normal".
F-series: Enter the main product’s menu 1.2 and select
"normal".
•External switch for changing the fan speed activated.
–Check any external switches.
•Silencers not correctly installed.
–Contact your installer!
