Connecting the water pipes to the hydro module
Danger!
Follow these instructions to prevent damage to the hydro module and
the other components of the system:
• Flush the water-side pipelines before connecting the device, to
remove impurities . Impurities can damage the components of the
device .
• Ensure that the components installed in the water circuit can with-
stand high operating water pressures . Use only suitable sealants
which can withstand the pressure and temperature of the system .
• Never use worn pipes .
• Do not use a pipe wrench to mount the connections . Use two adjust-
able spanners to tighten the connection .
Typical water pipe installation with dirt trap
➤
Install the pipelines, valves, and other components in accordance with
the planning documents .
➤
Install a dirt trap (to be provided by the customer) upstream of the
water inlet (water return) of the hydro module (grid width at least
500 to 600 µm) to protect the heat pump . We recommend installing
a shutoff valve upstream and downstream of the dirt trap, to make
subsequent maintenance work on the dirt trap easier .
