4.2
Installation space
The unit must be installed against a wall with sufficient load bearing capacity.
In case of light wall constructions, there is a risk of resonance noises.
Within 1 meter of the unit, there must be an earthed wall plug.
In order to prevent the condense outlet from freezing, the unit must be installed in a
frost-free room. Preferably ensure there is a space of at least 2 cm next to the boiler.
No free space is required due to danger of singeing.
4.2.1
Installing in kitchen cabinet
The unit can be placed between two kitchen cabinets, or inside a kitchen cabinet.
Make sure there is sufficient ventilation at the bottom and the top.
If the unit is installed inside a cabinet, ventilation openings of at least 50 cm
2
are
required.
4.2.2
Removing cover plate and front panel
For various activities on the unit, the cover plate and front panel have to be removed
from the unit, if they were installed. Do this as follows:
•
If you are using the cover plate (A), remove it to the front.
•
Unscrew both screws (1) behind the display window.
•
Pull the bottom of the front panel (2) forwards.
Danger: risk of burning
In case of high leaving water set ponts for space heating (eighter a high fixed set point
or a high weather-dependent set point at low ambient temperatures), the heat
exchanger of the boiler can be very hot, for example 70°C.
Beware that in case of a tapping demand, the water can initially have a higher water
temperature than requested.
In this case, it is recommended to install a thermostatic valve to prevent scalding.
This can be done according to the schematics below.
a=boiler, b=DHW from boiler, c= cold water inlet,
d=shower, e=thermostatic valve (field supply)
