INSTALLATION
SERVICE AREA
Make sure to respect the following measurements for the correct operation of the unit.
WATER DRAIN
The indoor drain unit (of condensate water) has 3/4” MPT connection.
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
Air duct dimensions will be determined according to the airflow and available pressure of the unit.
Ducts must be designed by qualified technical people.
Use ducts made of non-inflammable materials in order to avoid any risk of fire as a consequence of the
deflagration of gases. It is advisable to use metal sheet duct with insulation.
Use flexible ducts to connect air ducts into the unit and thus avoid vibration and noise transmission.
