Installation
The appliance must be installed in accordance with current safety regulations in the destination country, and with
the instructions in this booklet.
Mounting
The appliance must be wall-mounted in an upright position.
Make sure that the appliance is level in order to ensure faultless operation.
The ducts used for conveying air must be of the correct size. The ducts to and from the outdoors must be
thermally insulated and not subject to vibration.
The 150 mm standard diameter inlet and outlet ducts must be secured to the corresponding ports of the
appliance by means of clips or other suitable fastening systems.
If stale air is exhausted via the roof, the outlet must be designed so as to prevent the formation of condensate
and the entry of rain water. If fresh air enters via the roof, the intake must be designed so as to prevent the
formation of condensate and the entry of rain water.
Condensate drain
During normal operation, condensate collects at the
bottom of the appliance in a double tray provided with
two drain outlets. The connection points are located
at the back of the appliance, towards the bottom. The
condensate drain can be provided by connecting the
drain outlets to two flexible hoses with an internal
diameter of 19 mm approx. A siphon trap should be
created to prevent air bubbles from forming.
Important instructions:
---winter operation: high likelihood of condensate
formation; drain hoses must be connected, with a
siphon trap. (Fig.3a)
---summer operation: condensate formation likely;
drain hose connection, with a siphon trap, is
recommended. (Fig.3b)
Cut the end of the hose obliquely.
