– 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.
1. Insulate the lines (including those running below
ground) with UV-resistant and high-temperature-res-
istant insulation between the product and the heating
installation.
2. In order to avoid transferring vibrations to the surround-
ing buildings, use flexible connection pipes on the
product that have a length of at least 0.75 m.
3. When the product is not installed at the highest point in
the heating circuit, install additional purging valves in
suitable places.
4. Install the following accessories in the heating return.
Installation without decoupling hydraulic module
– Drain cock
– Air separator (if required)
– Dirt filter
– An expansion vessel suitable for the complete hydraulic
installation
– Expansion relief valve 0.3 MPa (3 bar)
– Pressure gauge (recommended)
Maximum length of the
heating circuit DN 26 DN 28
When using a hydraulic
module without an expansion
vessel 50 m 30 m
Note
If you use glycol, you must collect it at the
expansion relief valve to prevent environ-
mental pollution.

5. Remove the covering caps (3) from the product's hy-
draulic connections.
6. Install a dirt filter in the heating circuit return between
two stop valves so that the filter can be cleaned regu-
larly.
