Caution!
Risk of malfunction!
Dirt filters may lead to flow rate problems
and a reduction in the residual pump head
for the brine pump.
>
Do not install dirt filters for a prolonged
period in the brine circuit. The brine fluid
is cleaned during the filling process.
b
Caution!
Risk of damage caused by the formation
of condensation.
Condensation on uninsulated brine pipe-
lines within the building may lead to struc-
tural damage.
>
You must insulate all brine pipelines
using vapour diffusion-tight insulation.
>
Fit the brine pipelines between the heat source and the
heat pump along with all the associated components in
accordance with the applicable technical guidelines.
i
To prevent freezing, use cold pipe clips to con-
nect the brine pipelines to the heat pump.
>
Connect the brine pipelines to the heat pump ( 3 ) and ( 4 )
(
¬
Fig. 5.8 ).
>
Insulate all pipelines using vapour diffusion-tight insula-
tion.

b
Caution!
Risk of damage from escaping brine.
If the lower screw coupling on the brine
expansion tank (
2 ) has been sealed using
Teflon tape or something similar, this may
lead to leaks in the brine circuit.
>
Seal this screw coupling with hemp.
i
The brine expansion tank from the accessories
has a volume of approx. 6 litres and is therefore
adequate for brine circuits up to a maximum of
500 litres. For larger volumes, other expansion
tanks that are fitted on-site must be installed.
>
Use the dowel and the screw to fit the bracket ( 3 ) for the
expansion tank to the wall.
>
Unscrew the prefitted connecting pieces ( 1 and 2 ) from
the brine expansion tank ( 57 ).
>
Put hemp on the outside thread of the lower connecting
piece.
>
Install the brine expansion tank with the lower connect-
ing piece in the pipeline from the heat source to the heat
pump.
