Unit positioning
In case of ceiling (or false ceiling) installation, unit is already provided with vibration supports.
With referrement to fig. 5-3, here below mounting instructions :
1. Drill the ceiling for fixing the four M8 threaded rods (1).
2. Place the unit on the rods by the corner supports already mounted (6).
3. Insert rubber vibration supports (2), washers (3) and screw nuts (4) and locknuts (5) without tightening.
4. Get a min 3 mm slope towards the drain trap points in order to make drainage easy.
5. Tighten nuts and locknuts.
In case of floor installation, between unit lower panels and the floor a min 150 mm gap space is needed (for this purpose,
use option PD2 support kit), so that drain traps can be installed.
Connection to the air ducts
FANS SHALL NOT BE RUNNING WITHOUT CONNECTION TO THE DUCT !

Air ducts shall be sized according to unit air performance in terms of external static pressure and airflow rate

In order to prevent condensation and reduce noise level insulated ducts are strongly recommended.

Between unit and air ducts always interpose vibration joints. Ensure electrical continuity between unit and
(metallic) ducts by a ground cable.
Water connections
These operations shall be carried out by qualified personnel only.
Condensed water discharge connections

The drainage system shall be provided with a drain trap on each condensed water outlet; drain trap is needed to
