1. Remove both screws (A).
2. Pull the side casing downwards and then forwards.
Note
Note that the required tool is not included in
the scope of delivery.
5.2.2 Aligning the product
1. Only use bolts of a specific length.
Maximum length: 8 mm
2. Align the product horizontally so that condensate can
flow.
Note
The product must be installed with the vi-
bration-isolating feet supplied. The product
is lifted by the vibration-isolating feet, which
simplifies the condensate-discharge process
and reduces vibrations.
3. Screw in the vibration-damping feet using the concrete
foundation.
Note
The concrete foundation must not be joined
to the house foundations.
5.3 Hydraulics installation
In heating installations that are equipped primarily with ther-
mostatic or electrically controlled valves, a constant and suf-
ficient flow through the heat pump must be ensured. Irre-
spective of which heating installation is selected, the min-
imum volume of circulating heating water (40% of the nom-
inal flow, see the technical data table) must be guaranteed.
5.3.1 Carrying out the hydraulics installation
Caution.
Risk of damage caused by residue in the
heating flow and return.
Residue from the pipelines, such as welding
beads, scale, hemp, putty, rust and coarse
dirt, may be deposited in the product and
cause malfunctions.
Flush the heating installation thoroughly
before connecting the product in order to
remove any possible residue.
Caution.
Risk of material damage due to corrosion.
If plastic pipes that are not diffusion-tight are
used in the heating circuit, this may lead to
corrosion and deposits in the heating circuit
and in the product.
Do not treat the water with corrosion pro-
tection agents if plastic pipes that are not
diffusion-tight are used.
Danger!
Risk of material damage caused by sol-
dering work.
Carrying out soldering work on lines that
have already been installed may damage the
seals.
Solder the lines before installing the
product.
