3.5 Brine system
The brine system, i.e. the ground collector loop, must be assembled and
connected by a qualified tradesman in accordance with current regulations
and design guidelines.
Extreme care must be taken to ensure that no dirt gets on the collector
hoses, which must be washed clean before being connected. The protective
caps must remain in place at all times while work is in progress.
The temperature of the brine system can fall below 0 °C. It is therefore
important that no water-based lubricants and similar are used during
installation. It is also important that all the components are insulated against
condensation to prevent the build-up of ice.
i
We recommend
that you follow the
installation instructions
from the local Heat
Pump Association.
!
It is very important that
the branch pipes are
the same design so
that as equal a pressure
drop as possible is
achieved in both the
sets of pipes (pipe
dimensions, bends,
etc.).
