Vehicular transport
!
Material losses
The appliance must generally be stored and transported
vertically.
The appliance may be transported horizontally for brief periods,
over a maximum distance of 160 km and on made-up roads.
Strong shocks are not permissible.
!
Material losses
If transported horizontally, the appliance must always be
laid on the shaded side of the box.
The appliance must not remain in a horizontal position
for more than 24 hours.
If the appliance was transported horizontally, leave it to
rest in a vertical position for at least one hour before
commissioning.

1 Recessed grips
Transport from vehicle to installation room
The cardboard box has reinforced recessed grips along the top.
You can use these recessed grips, as well as the pallet at the lower
end, to carry the appliance into the installation room. Take note
of the weight of the appliance and ensure sufficient personnel
are available.
9.2 Storage
If it is necessary to store the appliance for a prolonged period
before installation, observe the following information:
- Only store the appliance in a vertical position. Never store
the appliance horizontally.
- Store the appliance in a location that is dry and largely
dust-free.
- Protect the appliance from coming into contact with aggres-
sive substances.
- Ensure the appliance is not subjected to shocks or vibrations.
9.3 Installation site and location of air extraction
or air intake
!
Material losses
Observe the lower application limit for the appliance. The
temperature of the air discharged from the appliance may
be lower than this value. This may arise if DHW is drawn
off intensively, for example, i.e. in excess of usual house-
hold consumption. If cold air is admitted into rooms in
the building, this can lead to frost damage, e.g. on water
pipes.
!
Material losses
Please observe the installation site requirements listed
below and the air extraction or intake locations. Failure
to observe this point puts the appliance at risk of damage.
- The appliance is not approved for outdoor installation.
- If outdoor air is used as a heat source when outside temper-
atures are low, condensate may form on the appliance if the
relative humidity is unusually high, i.e. in excess of 75 % and
with a room temperature of 22 °C. Such high relative humid-
ity levels will damage the fabric of the building and must be
prevented by ventilation.
- 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 free from the risk of frost.
Please note that the temperature in the installation room, or
in the room into which the air is admitted, can fall below 0 °C
during the appliance runtime.
- The ambient temperature of the appliances and the air intake
temperature must be within the permissible application lim-
its (see "Specification / Data table" chapter).
- The floor of the installation room must be level and have suf-
ficient load bearing capacity. Take note of the weight of the
appliance with a full DHW cylinder (see "Specification / Data
table"). A floor with insufficient load bearing capacity is in
danger of collapse. If the appliance is not level, there may be
a risk of appliance damage.
- The size of the installation room must correspond to the
appliance application limits (see "Specification / Data table"
chapter).
- Observe the safety clearances and protection zones.
- Always leave sufficient space to provide access for installa-
tion, maintenance and cleaning. Observe the minimum clear-
ances (see "Preparations / Siting the appliance").
- Ensure the operation of other equipment in the installation
room is not impaired.
- To keep the duct lengths as short as possible, we recommend
installing the appliance close to the kitchen or bathroom.
- To prevent adverse effects from operating noise, do not in-
stall the appliance close to bedrooms.
