INSTALLATION

Preparations

9. Preparations
9.1

Transport

CAUTION Injury
!
f Take note of the weight of the appliance. f
f Use suitable transport aids (e.g. a sack truck) and f
enough personnel for transportation.
Material losses
!
The appliance casing is not designed to withstand strong
forces. Incorrect handling can lead to material losses of
considerable extent.
f Observe the information on the packaging. f
f Only remove the packaging shortly before the instal- f
lation.
- Store and transport the appliance in its packaging.
- You may transport the appliance carefully over short distanc-
es at an angle of up to 45°.
- During storage and transport, the ambient temperature
should be between -20 °C and +45 °C.
Vehicular transport
Material losses
!
The appliance must be stored and transported according
to the instructions on the packaging.
9.2

Storage

If it is necessary to store the appliance for a prolonged period
before installation, observe the following information:
- Leave the appliance in its packaging during storage.
- Only store the appliance in a vertical position.
- Store the appliance in a location that is dry and largely
dust-free.
- Protect the appliance from coming into contact with corrosive
substances.
- Ensure the appliance is not subjected to shocks or vibrations.
9.3

Installation site

The appliance is not approved for outdoor installation.
Further requirements regarding the installation room and appli-
ance positioning, to prevent appliance damage:
- The installation site must be free from flammable, highly
combustible gases and substances, as well as high levels of
dust.
- The installation room must be dry and free from the risk of
frost.
- The intake temperature of the appliance must be within the
permissible application limits (see chapter "Specification /
Data table").
- The appliance must be installed on a even, horizontal sur-
face. If the appliance is not horizontally level, there may be a
risk of appliance damage.

- Ensure the appliance is not subjected to shocks or vibrations.
Use the anti-vibration mounts supplied.
- Observe the safety clearances and protection zones.
- Always leave sufficient space to provide access for instal-
lation, maintenance and cleaning. The required minimum
clearances must be maintained (see chapter "Minimum
clearances").
- Ensure the operation of other equipment in the installation
room is not impaired.
- Lighting equipment and pipes must not be installed above
the appliance.
- To keep the duct lengths to the draw-off points as short as
possible, we recommend installing the connected DHW cylin-
der close to the kitchen or bathroom.
- To prevent adverse effects from operating noise, never install
the appliance close to bedrooms.
- Observe the minimum volume of the installation room and
the heat-up time during normal domestic use (see chapter
"Specification / Data table").
- In recirculation air mode, when selecting the type and size
of installation room, ensure that energy use is compensated
over a period of 24 hours and the lower application limit of
the appliance is not undershot.
Please also observe the following factors: Expected runtime
per day, the resulting cooling energy, existing heat sources
in the installation room (e.g. freezer, tumble dryer, central
heating), heat flux from adjoining rooms.
The following installation sites and air draw-off points are not
permissible, as there may be a risk of appliance damage:
- Places where the air contains ammonia (e.g. sewage works,
animal sheds)
- Locations where the air is contaminated with oil or grease
- Generally places with a loaded or aggressive atmosphere
(e.g. cement or flour dust, hairspray (e.g. hairdressing salon)
- Saline environments (e.g. in areas < 2-5 km from the coast,
depending on main wind direction)
- Locations where the air contains chlorine or chloride (e.g.
swimming pools, salt works)
- Environments with thermal water
- Areas in proximity to high frequency machines (inverters for
large motors, radar)
f Also check in the wider environment around the planned f
installation site for anything which may have adverse effects
on the installation site or the air supply.
Note
You can improve the efficiency of the appliance by utilis-
ing the waste heat from other appliances to heat the DHW
cylinder, e.g. boilers, tumble dryers or freezers.
