Hydraulic connections
!
Please note
To prevent equipment dam-
age,
connect on-site secondary
lines to the heat pump so that
they are free of load and tor-
que stresses.
!
Please note
Make tight hydraulic connec-
tions on the secondary side.
In the case of hose outlets,
ensure diaphragm grommets
are seated correctly (if neces-
sary, seal with sealing tape,
see page 101).

3. Fill and vent secondary circuit.
4. Thermally insulate pipes inside the
building.
Note
■ In underfloor heating circuits, integrate
a temperature limiter on site for limiting
the maximum temperature of under-
floor heating systems.
■ Safeguard minimum flow rate, e.g.
with overflow valve (see Specification
on page 134).
