5. Assembly and hydraulic installation
5.1. Assembly of indoor unit
AERO SLM heat pumps must be installed in a frost-
protected room by an approved specialist. The room
temperature must be between 5°C and 25°C.
If the minimum size of the installation room falls below
the required value, the room must be designed ac-
cording to EN 378. It is not permissible to install the
equipment in humid or dusty rooms, where there is a
risk of explosion.
The connections for the refrigerant pipes are on the
back side of the AERO SLM. The distance to the wall
on the back side of the heat pump must be large
enough to allow easy soldering when connecting
refrigerant piping. a distance of at least 100 mm to the
wall has to be respected. This measure is a recom-
mendation and varies depending on the site situation.
In order to avoid structure-borne sound transmissi-
ons, the heat pump must be installed on a horizontal,
level and weight-bearing surface (concrete plate or
similar). In the case of
fl
oating screed, the screed and
the impact sound insulation must be recessed around
the heat pump to ensure low noise levels when the
heat pump is operating (see adjacent illustration).
The AERO SLM must be put on the delivered
noise insulation pad. Make sure that the sound
insulation underlays are placed under the heat
pump as shown in the adjacent picture. When
delivered, the pads are located on the machine,
under the packing material.
CAUTION:
Do not confuse with packaging material.
The connections for the heating supply and return are
located inside the housing and can be led out either
on the right or left side of the heat pump.

The cable inlet for the sensors, the main current and
the LAN-connection are located on the backside of
the AERO SLM.
The relevant laws, regulations and standards must be
observed, in particular EN 378 parts 1 and 2 as well
as BGR 500.
