4 Pipe connections
General information
Pipe installation must be carried out in accordance with
the current standards and directives.
The pipe dimensions should not be less than the rec-
ommended pipe diameter according to the table below.
However, in order to achieve the recommended flow,
each installation must be dimensioned individually.
The system can be used with a low- and medium-tem-
perature climate system. The recommended tem-
perature of the heating medium at the dimensioned
outdoor temperature DOT must not exceed 55°C on
the supply and 45°C on the return circulation from the
climate system. BA-SVM 10-200 can reach up to 65°C
when using the electric additional heat or another peak
heat source.
An overflow pipe must be routed from the safety valve
to a suitable drain. The entire length of the overflow
pipe must be inclined towards the floor drain to pre-
vent water pockets and must also be frost-proof. In or-
der to reach maximum system efficiency, we recom-
mend installing BA-SVM 10-200 as close as possible to
the outdoor heat pump.
The BA-SVM 10-200 unit is not equipped with a shut-
off valve for the climate system. In order to facilitate
future servicing, the shut-off valves should be in-
stalled on the outside of the indoor unit.
The BA-SVM 10-200 unit can be docked to the central
heating, cooling operation and hot water systems. It
is absolutely necessary to install the supplied safety
assembly on connection XL11.

CAUTION
All high points in the climate system must be equipped
with air vents.
CAUTION
The pipelines need to be flushed out before the indoor
unit is connected so that any debris cannot damage
component parts.
CAUTION
Until the system’s heating/cooling circuit has been
filled with heating medium, the switch (SF1) in the
controller must not be set to “I” or „ ”. If you do not
comply with the above instructions, many compo-
nents of the BA-SVM 10-200 unit may be damaged.
Minimum system flow
The installation must be dimensioned at least to the
extent required to manage the minimum defrosting
flow at 100% circulation pump operation, see table.
CAUTION
An incorrectly dimensioned climate system can result
in damage to the appliance and lead to malfunctions.
BA-SVM 10-200 is equipped
with an expansion vessel with
a 10l capacity. The pressure set-
ting in the level vessel should
be set according to the maxi-
mum height (H) between the
vessel and the highest-posi-
tioned radiator, see drawing.
An initial pressure of 0.5 bar
The expansion vessel’s volume must be at least 5% of
the system’s total volume. BA-SVM 10-200 appliances
have been equipped with an expansion vessel with a
10l volume. If the capacity of the built-in expansion
vessel is insufficient, an additional expansion vessel
meeting the above requirements should be added to
the installation.

H
(5 mvp) means a maximum permissible height dif-
ference of 5 m. The maximum volume of the system
without a boiler is 220 l at the above initial pressure.

CAUTION
In the installation before the BA-SVM 10-200, a par-
ticulate filter should be used, dedicated for heating
installations. The filter will protect the unit against pol-
lution.
CAUTION
Ensure that incoming water is clean. When using a pri-
vate well, it maybe necessary to supplement with an
extra water filter.
