WATER DRAIN
All the drains are provided with a 3/4” male gas connection.
The diameter of the condensate drain pipe shall be equal or larger than the unit connection depending on
the line length and the building configuration.
The drainage line shall have a slope of not less than 2% to guarantee the correct evacuation of the
condensate water.
When the drain line is exposed to air temperatures below 0 degrees, thermal insulation or electrical heating
wires shall be used to prevent the water from freezing and avoid the possible following tube damages.
Install a siphon with the appropriate dimensions (refer to drawing).
AIR DUCTS
The air duct dimensions will be determined according to the air flow and the available static pressure of the unit.
They shall be designed by qualified technicians. An incorrect design may reduce the unit’s performance and may
be a hindrance when access to the unit for maintenance operations is needed (in particular where there is only one
possible access).
Use ducts made of non-inflammable material in order to avoid any risk of fire as a consequence of the deflagration
of gases. It is advisable to use insulated metal ducts.
Use flexible conduits to connect air ducts to the unit so as to avoid vibration and noise transmission
.
The following shall be taken into account regarding the units that include several circuits with separate ventilation
systems and where there is the possibility that the fan of one circuit stops while the other one remains active:
Install separate air ducts for each circuit TO AVOID reverse air flow.
