7.2 Air Connection
7.2.1 Air Connection General
Information
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Only operate the heat pump with the air ducts connected.
The glass fibre reinforced concrete air ducts offered as accesso-
ries are moisture-resistant and diffusion-free.
The sealing collar is used to seal the air ducts on the heat pump.
The air ducts are not screwed directly onto the heat pump. Only
the rubber seal comes into direct contact with the heat pump
when the system is installed correctly. This guarantees easy as-
sembly and disassembly of the heat pump and also ensures that
solid-borne sound is well insulated.
If another type of air duct is used, observe the external and inter-
nal dimensions as specified in the figure. Also ensure that the vi-
bration and duct insulation are adequate.
If flange-mounted air ducts are used, connecting stubs are se-
cured on the air inlet and air outlet sides of the evaporator with
4 M8x16 hexagon bolts in the threaded holes provided. When
doing this, ensure that both air duct stubs only touch the insula-
tion. There should be no contact with the external sheeting.
