connections
NOTE
The safety valve that is integrated or included
in delivery has a tolerance of plus / minus
10% for the set pressure. If local regulations,
laws, standards or directives require a
smaller tolerance range, the safety valve
must be replaced on site with a safety valve
that meets the requirements.
IMPORTANT
can cause damage to the heat pump.
Ensure that a sludge separator is installed in the
hydraulic system.
Rinse the hydraulic system thoroughly prior to es-
tablishing the hydraulic connection of the heat
pump.
IMPORTANT
Damage to the copper pipes due to unacceptable
loading!
Secure all connections against twisting.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned. In do-
ing so, ensure that the connection pipework be-
tween the heat pump and hydraulic tower are also
taken into account.
Freely pressing the recirculating pump produces
at least the minimum throughput required for the
ceiling at a maximum distance of 20 cm from the
centre of the respective unit connection.
Insert the vent at the highest point of the heating
circuit.
