Hydraulics installation
▶
Observe the relevant information about hydraulic installa-
tion in the appendix and in the system instructions.
5.1
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 heat pump and
cause faults.
▶
Flush the heating installation thoroughly
before connecting the heat pump in order
to remove any possible residue.
Caution.
Risk of damage caused by leaks.
Mechanical stress on connection cables may
cause leaks and damage to the product.
▶
Avoid mechanical stress on connection
cables.
1.
Install the connection cables in accordance with the
dimension and connection drawings.
2.
Position the pipe brackets for securing the heating
circuit and solar circuit piping so that they are not
too close to the heat pump in order to prevent noise
transmission.
Note
The heat pump's compressor has two-fold vi-
bration insulation. This eliminates vibrations
in the refrigeration circuit that are inherent in
the system. However, under certain circum-
stances, residual vibrations may occur.
3.
If required, instead of pipe brackets, use cold insulation
brackets with additional rubber insulation and, in some
cases, reinforced hoses (armoured rubber hoses).
4.
To prevent excessive pressure losses on the heating
water side, do not use stainless steel corrugated pipes.
5.
Attach purging valves to the heating installation.
