Heating System Hydraulic
Connections
AEROTOP T heat pumps can be
connected in any desired layout.
The hydraulic connections require
flexible ducts to avoid noise trans-
ference from pipe openings and solid
bodies to the distributor network and
from there to the heating elements
such as radiators, etc. The ducts can
be directed from the right or left and
are connected to the inside of the heat
pump.
The ductwork must be carried out in
such a way that pressure drops at the
nominal volume flow do not exceed
the available pressure since this would
result in a reduction of the heat pump
output. This means that ducts cannot
have elbows that are too narrow.
Pipes and ducts must also be sufficient
insulated to prevent unnecessary heat
loss and the formation of condensate,
which could damage the pipe and duct
system or the installation location.
Dimensions
Heater flow Ø 1” (T07-T16),
Ø 1 1/4” (T20-T35),
flexible. Heater return Ø 1” (T07-T16),
Ø 1 1/4” (T20-T35), flexible,
Condensate Drain Ø 25/31mm, flexible.
For each heat pump we offer hydraulic
standard schemes. The integration of
these variants guarantee a safe and
faultless operation.
The system must be thoroughly
flushed before connecting to the heat
pump.
Residues in the heat pipes lead to
damages on the heat exchangers und
to malfunction of the heat pump.
Especially if there is no buffer storage
it is recommended to a dirt trap in the
heating return flow.
The water filled into the heating system
must be handled in accordance with the
rules and regulations of the relevant
professional associations.
It is important to ventilate the heating
system. If not the correct operation of
the heat pump is affected. Therefore
an exhauster must be provided. The
compact heat pumps have an
exhauster installed in the flow.
Condensate Drain
The condensate drain should be as
close to the heat pump connection as
possible. To prevent room air or
canalization waste air from being
sucked into the heat pump, the
condensate drain must be connected
airtight to the heat pump using a
siphon with a min. height of 100 mm.
The condensate drainage pipe cross--
section may not be reduced and must
be at a continuous 2% incline to ensure
water can be sufficiently drained.

Connections
Lines are connected at the left side of
the unit by default. If the right side is
preferred, the panels (1 and 2) can be
switched with the panels from the left
side. Ducts and cables are pulled to
the other side inside of the unit and
through the opening in panel 1.
