Dachs Pro 20 ST
Reference:
Please observe the instructions and information in the iav Documentation of VW
on the EcoBlue 2.0 (Generation 1.2) -
Chapter 6.8 Gas supply
in particular.
For operation, the following protective measures are recommended:
●
The volume of recharging water is to be kept low by the installation of sectioning valves in case any repair needs
to be carried out and to enable regular inspection of the expansion vessel.
●
Addition of chemicals for stabilisation of hardness should be avoided since calcium carbonate may occur in the
form of sludge.
●
The safest methods for avoiding the formation of stones are softening and desalination in cation exchange, ion
exchange or reverse osmosis.
5.2.3 Heating installation and return temperatures
Heating installation
●
During installation, the Dachs Pro 20 ST assembly instructions and local requirements are to be observed.
●
For integration on the heating water side, DIN 4751/T2 is to be observed (absolute temperature of the heating
vessel < 100 °C).
Maximum and minimum return temperature:
●
Admissible return temperatures in control operation are 30 °C to 70 °C. The temperatures must be under 30 °C
during permanent operation.
●
Temperatures below +10 °C are admissible.

5.2.4 Gas installation
Attention:
Gas installation is to be implemented in accordance with the technical regulations of the local gas suppliers and
the TRGI/TRF and may only be carried out by specialist staff with respective authorisation for working with gas.
!
Note:
The gas supply line provided on site must be equipped with a gas flow monitor (on site).
Regarding energy tax exemption, a gas meter or thermal energy meter
must
be installed on site.
i
Note:
The gas pressure of the supply line is to be checked already in the planning phase. If the pressure in the gas
line exceeds 54 mbar (LPG) or 24 mbar (natural gas), a pressure reducer has to be installed to reduce the gas
pressure at rest to a maximum of 50 mbar (LPG) or 20 mbar (natural gas).
