2.1.2 UNIT POSITIONING
Unit placement
The unit can be installed close to the wall with the pipes
directly outwards or away from the wall by making a
minimum of ducts to arrive with the pipes outwards;
-For ducted installation, leave the dn250mm male fittings
on the unit which will be used to connect the pipes to the
outside;
The ducted installation provides for the possibility of
creating a maximum of 8 meters of ducting;
For non-ducted installation the unit does not provide
ducts but installation directly adjacent to the wall and
direct outwards holes;
In this case it is possible to leave the fittings if the
centering of the holes towards the outside is very precise
or to remove them to bring the unit in adherence with the
wall;

2.1.3 CONDENSATE DRAIN CONNECTION
Due to the heat recovery system (the hot exhaust air is cooled by the intake air inside the heat exchanger), the humidity contained
in the indoor air condenses inside the unit.
For the correct operation of the heat recovery unit, it is therefore necessary to connect a condensate drain to the hydraulic system
or to leak to the outside. Furthermore, to allow the condensate water to drain correctly and avoid sucking in air, the condensate
drain must always be equipped with the appropriate siphon by the installer;
To install the condensate drain, comply with the following standards:
•give a slope of at least 2% to the exhaust pipe;
•provide for the possibility of disconnecting the drain hose for any maintenance (in particular in the case of ceiling
installation);
•make sure that the discharge end of the pipe is at least below the water level of the siphon;
•make sure that the siphon is always full of water and of sufficient height (at least 30-40 mm)
On the machine, the exhaust is located on the left
side;
A Dn 20 silicone tube is supplied inside the side which
has a length of 80 mm in order to facilitate the exit
from the machine and the connection with the
condensate drainage network;
There are then two possibilities of exit on the side,
both rear and side;
Remove the part chosen for the condensate drain
outlet and pass the pipe in that point;
- ATTENTION TO THE HORIZONTAL SECTIONS FOR THE
CONDENSATE DISCHARGE WITH INSTALLATION

IF WATER STAINS AND THE EXTERNAL TEMPERATURES
ARE BELOW 0 °, THERE IS A DANGER OF FREEZING
THE DRAIN AND THEREFORE POSSIBLE INTERNAL
WATER LEAKS;
