Introduction
Congratulations on purchasing your new CORE ERV - Energy
Recovery Ventilation. The exchanger is classed as an
Enthalpy Exchanger. In this system, in addition to the heat that
is recovered from two air currents, the moisture is also
automatically recovered. This takes place via a membrane
inside the ERV and, in addition to exchanging energy, ensures
a comfortable room climate.
The ERV is a component for energy recovery (recuperation)
for ventilation devices that are designed for living spaces. The
ERV is not designed for any other operating mode.
Notes on packaging and shipping
Even though an ERV appears to give the impression of being
robust and sturdy, applying heavy weight to pallets whilst
storing or transporting, especially in combination with high
temperatures, can lead to distortion and damage.
For shipment of larger quantities, it is recommended:
- Pallets with sufficient load capacity
- No stacking over 1.6 m high
- contactless packaging with foil
- securing the ERV on the pallet with a lid (cardboard)
and straps made of polypropylene.
•
For shipment of single ERV, it is recommended:
- A box suitable for parcel shipping
•- Appropriate stabilization as a transport safeguard (e.g.
very coarse (> 10 mm), non-dusting filling material, no
bubble wrap!)
The weight of your ERV varies greatly depending on the type
and height. In the following table you will find the minimum
requirements we recommend for cardboard packaging for
each weight:

Notes on storage
The temperatures during the entire life cycle of the ERV must
be within the limits of - 20 ° C to + 50 ° C. Otherwise there is

a risk of distortion, the odour formation, the occurrence of
leaks or other kind of damage. All of this reduces the high
performance of your ERV.
Never stack multiple ERVs higher than 1.6 m and do not
load an ERV with more than 30 kg. Do not load an ERV
unevenly.
Always place an ERV on one of its closed surfaces.
If you replace an ERV during the summer time with an HRV,
please make sure to store the ERV in a dark, cool place and
take in account the maximum load mentioned above.
Notes for handling and installation
The ERV is completely ready for installation. Please do not
use any additional oils, sprays, talc or other lubricants for
installation in order to make the ERV easier to slide into the
socket.
Please do not let the ERV fall and avoid strong forces.
The strapping attached at the factory is important. It is not
packaging material and should NOT be removed. It is used to
facilitate installation and maintenance of the ERV. The
strapping is not designed to carry the weight of the ERV during
continuous transport!
Due to the manufacturing process and to maintain the high
technical performance, the side surfaces of the ERV are
permanently sticky.
Especially at temperatures > 30 ° C, it is possible that
materials, especially foils, stick to the sticky surfaces.
Avoid forcefully pressing the packaging materials to the ERV
unit whilst in storage or during transport.
Notes on usage
The ERV is designed for living areas.
If you want to operate an ERV in a ventilation device, please
check beforehand whether the ventilation device is
suitable for use with an ERV!
Before an ERV can be put into operation in a ventilation
device, the corresponding device settings must be made.
Your ventilation unit manufacturer will inform you about the
corresponding settings.
The ERV has a very high technical performance, which is
due to the latest membrane technology. Thus, in contrast to
the HRV, an ERV is a high-tech product due to the
membrane, which reacts more sensitively to environmental
influences. The membrane is highly selective regarding the
substances that are transferred and is resistant to
surfactants (washing chemicals). However, due to the
complex composition of the membrane, there is always a risk
of reaction with chemicals and a 100 % selectivity for the
transmission regarding chemicals cannot be guaranteed.
If you carry out renovation work, use strong cleaners or
oils for floors and furniture or other chemicals, including
biologically produced, biodegradable and bio-based
chemicals, in quantities > 50 ml, we recommend
removing the ERV from the ventilation unit, switching off
the ventilation unit and, at least for the time of work,
better still a few days to a week afterwards, to replace
with an HRV and to ventilate the affected area
extensively with open windows and doors.
In this way, you avoid the transfer of odours (see chapter
Odour) and possible damage to the membrane, which
cannot be restored using the recommended cleaning
procedure. The influence of chemicals can reduce the high
technical performance of your ERV.
The ERV is not designed for applications in areas with a high
chemical load, including workshops and production halls.
The ERV may only be used in office and living areas!
We recommend cleaning the ERV with water once a year so
that the high degree of moisture transmission is maintained.

The temperatures during the entire life cycle of the ERV must
be within the limits of - 20 ° C to + 50 ° C. Otherwise there is
a risk of distortion, Odour formation and the occurrence of
leaks. All of this reduces the high performance of your ERV.
Notes on cleaning
A dirty ERV can be cleaned and disinfected. You can find
detailed information on the washing and disinfection process
in our cleaning instructions.
Notes on disposal
Please dispose of a visibly soiled ERV, which can no longer
be cleaned, as well as a damaged ERV or those that are to be
disposed of for reasons of age by putting them in the
household waste bin.
Notes on shelf life
The ERV will lose a small part of its high technical
performance in the course of its life cycle. This is due to the
aging of the materials and different levels of environmental
influences. The composition of the airflows have a strong
influence on the aging of the ERV, which is why the ERV is
only designed for residential areas.
An ERV can be operated for up to 10 years without
interruption if the conditions under the instructions for
handling, use and storage are complied with. In the case of
storage, the storage time is deducted from the specified 10
years of operation life. The 10 years start from the date of
manufacture (see type plate on the ERV).
Notes on materials
The ERV consists largely of high-quality polystyrene and a
small part of adhesive and sealing material. Some ERV types
have a metal housing and / or additional aluminum side grilles
instead of the plastic housing, which do not affect the
performance.
Some of the adhesives used are permanently sticky, which is
why sticky surfaces or stickiness on the inside can still occur.
This is not an indication of reduced quality or a
manufacturing defect
Notes on conformities / certificates / standards
Our ERV comply to the following conformities / certificates /
standards:
Hygiene standard: DIN ISO 846
Fire standard: EN DIN 13501, ISO 11925 (Class
E)
Quality management: DIN ISO 9001:2015
Notes on odour
An ERV consists exclusively of non-metabolizable plastics,
tested in compliance with the hygiene standard DIN ISO 846.
This means that no biofilms or mold shall be formed in an
ERV under the conditions of use specified in the respective
technical product data sheet. Therefore, odours due to
mould and/or bacterial infestation shall not occur. However,
if you suspect mould and/or bacterial infestation, please
follow the necessary steps for disinfecting according to the
cleaning instructions for ERV.
In addition to the odours caused by microorganisms, other
odours may arise when using an ERV. Please find here the
4 main types of smells with the corresponding recommended
actions.
1. Freshly produced
a. Smell plastic
b. Evaporates after a few days of ventilation
c. Action: Set the ventilation device to the
highest air exchange rate when you are
not at home and repeat the process until
the odour evaporates.

2. Odour due to downtime / storage
a. Smells Musty to "chemical"
b. Evaporates after a few days of ventilation
c. Action: Set the ventilation device to the
highest air exchange rate when you are not
at home and repeat the process until the
odour evaporates.
3. Odour transmission (Exchange of odours in the air
currents via the membrane)
a. Smell depending on the smell transmitted
and smells from outside or from other
rooms (very critical onions and garlic,
smoke? Tar?)
b. Evaporates after a few days of ventilation
c. Action: Set the ventilation device to the
highest air exchange rate when you are not
at home and repeat the process until the
odour evaporates. (We recommend an
extractor hood, especially if there are
kitchen smells!)
•
4. Odour due to unknown influences / damage
a. Odour undetermined (source unknown)
b. Builds up more and more over time and
does not dissipate after a few days or
weeks.
c. Please contact your service technician. You
can check a number of parameters yourself
in advance: checking the device settings,
air distribution and filter systems.
In addition to odours from the inside, odours from the outside
can also get into the interior via the ventilation system. These
odours can be "picked up" by the ERV and linger for a long
time.
With the products HRV and ERV there can be a small amount
of odour transmission due to air exchange through leakage.
However, this exchange takes place to such a small extent
that only substances with a very low odour threshold can be
perceived.
The risk of odour transmission is slightly higher with ERV
because, in addition to leakage, transmission via the
membrane cannot be 100% ruled out. The membranes we
use are technically of a very high standard and very selective
with regard to water molecules. This makes it difficult for
other molecules, e.g. VOC (volatile organic compounds), to
pass through the membrane.
Measurements show that, depending on the chemical
substance class and molecular size, organic compounds up
to 99% are blocked by the membrane.
Notes radioactive noble gas radon
When uranium and radium are present in varying degrees in
all soils and rocks decay, radon is produced, which spreads
through the soil and finally reaches the earth's surface.
Radon also reaches the interior of houses from the subsoil
of buildings, where it can accumulate. This can lead to high
radon concentrations, which are hazardous to health,
especially if the room is not ventilated very often.
Radon concentrations in the soil, in the air and indoors vary
locally and regionally.
The membrane of the ERV is permeable to air and thus also
to noble gases such as radon to a certain extent. However,
due to the membrane permeability, the exchange of radon
from supply and exhaust air is far below the exchange of air-
air due to the average leakage of an ERV or the ventilation
system itself.
By using a ventilation system in general, you ensure that
more fresh air gets into the interior and that accumulation
with radon, which can lead to a health hazard, can be
prevented. All of this is independent of whether you run an
ERV or an HRV in your ventilation system.
Notes Use on ships, coastal areas and islands
The ERV is a component for energy recovery (recuperation)
for ventilation units designed for living spaces. However, the
composition of the airflows has a strong influence on the
aging of the ERV.

Due to the increased salt content of sea air, deposits can
increase, which can affect the performance of the ERV. In
general, heavily soiled heat exchangers show a significant
reduction in moisture transfer. Previous studies give no
indication that the membrane is damaged by the increased
salt content in the air.
We recommend cleaning the ERV with water once a year so
that the high degree of moisture transmission is maintained.
In addition to odours from the inside, odours from the outside
can also get into the interior via the ventilation system. These
odours can be "picked up" by the ERV and remain for a long
time.
Notes on quality control
Every single CORE ERV exchanger goes through a 100%
quality control check before it leaves our factory. Our company
is certified according to DIN ISO 9001: 2015.
