A fan is installed in the appliance, which generates a negative
pressure in the device. If the negative pressure can no longer be
built up (damaged sealing tape), the safety pressure cell shuts
down the appliance. A message appears in the heat pump man-
ager.

Replace the sealing tape if required.
In the event of a leak, the fan mixes the refrigerant gas into the
air in the room sufficiently.

Increasing the minimum installation area
If the minimum installation area requirement cannot be met in
the installation room, the installation room can be connected to
a neighbouring room via ventilation apertures. The ventilation
apertures must be located near the ceiling and the floor. If the
ceiling is suspended and there is no wall to the next room, the
upper ventilation aperture can be dispensed with.
