Planning heat source – air
Assembly conditions and minimum distances from monobloc unit
• The heat output of the monobloc unit may not be prevented by
additional protection apparatus like sun blind or similar.
• Locations at which the outside temperature decreases below -20 °C
must be avoided.
• The minimum clearances (see gure) must be observed.
• A drainage system using a drainage pipe leading to a gravel bed
in the frost-free subsoil is recommended for draining melt water in
de-icing mode (see installation example on page 80).
• Objects that can lead to short circuit of exhaust air must not be
erected.
• The operational noise emission of the monobloc unit should not lead
to irritation of the users or neighbours.
- Use additional vibration-damping rubber buffers for
• If the monobloc unit is installed near the sea, in regions with a high
content of sulphur or at oily locations (e.g. machine oil, etc.), its
operational service life will be possibly shortened.
• For installation locations that can be inuenced by strong winds e.g.
when a wind blows between buildings, including on building, the
Monobloc unit must be secured on the building by means of an
additional protection against toppling (e.g. cable).
• The monobloc unit is only developed for outdoor installation and may
not be installed outdoors.
• Condensate should be able to be drained from the unit without
difculty.
