5. Interior installation
5.1. Installation Instr uctions
Interior installation of the heat pump is recommended.
This means that the work involved in frost protection
and condensation run-off heating can be avoided.
It also means that the inlet air / outlet air can be con-
veyed to the heat pump with the least possible heat
losses. Various installation options are described in
detail in the following chapters.
All components of the heat pump are insulated so that
no condensation is formed on the external parts even
at outlet air temperatures of -20°C. However, it is still
advisable to air the room regularly.
The heat pump is decoupled via vibration dampers.
The installation location should consist of a solid
base.
5.2. Heating Connection
A fl exible hose set is included as standard for heating
connections. See technical data for appropriate con-
nection sizes for specifi c machines. It is advisable to
use air source heat pumps only in combination with a
buffer tank such as the IDM Hygienik Tank.
5.3. Condensation r un-of f
Air source heat pumps generate condensation during
operation. With larger machines, up to 50l of water
can be extracted from the ambient air per day. The
condensation run-off should be conveyed into the
waste water channel via a siphon using the appropri-
ate pipe diameter for the machine.
5.4. Air Routing
The various air ducts (see accessories for interior
installation) and wall openings are designed specifi -
cally for the relevant machines in question. Effi cient
and fault-free operation can only be ensured if the
appropriately sized connection elements are used.
5.5. Air Inlet and Outlet
The options for how the air inlet and air outlet are
designed are varied. The list below provides design
guidelines:
- Air inlet side and air outlet side should always be on
two different sides of the building.
- Openings in the masonry must always be protected
against the penetration of foreign bodies (leaves,
small animals). To do this, mesh grilles should be fi t-
ted in light shafts, and weather-shield grilles should
be installed on visible walls.
- Wall openings must be created as per the specifi ca-
tions and insulated against damp penetration using
a closed-pore insulating material (minimum thick-
ness 50 mm).
Even light shafts which are too small
enlarge the pressure loss of the air rout-
ing. These must therefore be suffi ciently
large.
Light shafts must have a rainwater
run-off.
