Installation

Heating: louvre position for correct air flow.

Cooling: louvre position for correct air flow.

Max. 2 louvres closed

Warning: To close one or two air outlets use the special kit

Install the unit as centrally as possible in the room, the air flow direction can be controlled by manually regulating the louvres position, according to the operating mode (cooling or heating): this will ensure optimum distribution of the air in the room.

During cooling mode operation the best position for the deflecting louvres is one which allows air diffusion close to the ceiling (Coanda effect). In heating mode, the louvres should be positioned so that the air is directed towards the floor, in order to prevent layers of hot air forming in the upper part of the room.

In order to allow easy and rapid installation and maintenance, make sure that in the selected position it is possible to remove the ceiling panels or, if the ceiling is constructed of masonry, that access to the unit is guaranteed.

ATTENTION:

Only restrict the air outlets as indicated in the drawing.

Prior to installation

It is advisable to place the unit as close as possible to the installation site before removing it from the packaging. The grille panel and the control are separately packed for maximum protection.

IMPORTANT:

Do not lift the unit by the condensate drain discharge pipe; hold it by its four corners only.

Unit installation will be facilitated using a stacker.

If plaster board ceiling panels are installed the maximum dimensions of the unit housing must not exceed 660 x 660 mm (mod. 004 - 008 - 010) and 900 x 900 mm (mod. 012 - 016 - 020).

In rooms with high humidity, brackets should be insulated by self adhesive insulation supplied.

Installation

Mark the position of the hangers, connection lines and condensate drain pipe, power supply cables and remote control cable (see dimensions); the cardboard template (supplied with the kit) may be of assistance for this operation. Depending on the type of ceiling the hangers can be fixed as shown in the drawing.
