INSTALLATION
WATER DRAIN
The indoor dra
in unit (of condensate water) has a 3/4” gas (ISO 228-1, BSPP) male connection.
The condensate drain pipe diameter should be equal or larger than the unit connection depending on the line
length and general building configuration.
The drainage line should be inclined a minimum 2% for proper water evacuation.
When drain line is exposed to air temperatures below 0 degrees, it is necessary to cover with thermal insulation
or electrical heating wire to avoid water freezing and tube damage.
It is convenient to install the drain trap with proper dimensions (see diagram).
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 desig
n 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
.
