CASSETTE FAN COIL UNITS 42GW
Supply of conditioned air duct to
an adjacent room
Serviceability
■■ All the key components (motors, fans and drain pump) are
accessible from the bottom by simply removing the grille.
These components can be removed without disturbing
the other components or any surrounding ceiling tiles.
■■ This option allows supply of conditioned air to a room
located close to the Idrofan cassette through an air duct
(customer-supplied). If this option is used, the outlet corresponding to the duct must be closed, using the air supply
outlet obstruction kit provided. The kit cannot be used in
units equipped with electric heater. An air inlet grille must be
fitted (if possible near the floor) between the air-conditioned
room (where the unit is situated) and the adjacent room or,
alternatively, the door must be undercut.
■■ The duct lengths can be calculated in accordance with
the “air distribution to an ad jacent room” diagram in the
IOM, also taking into account the pressure drop through
air diffusers and fresh air filters.

Notes:
1. The louvres were adjusted to use the Coanda effect to obtain an air flow pattern that adheres as closely as possible and parallel to the ceiling.
2. The air throw is defined as the distance at which air flow speed falls to 0.2 m/s, when the air flow leaves the unit parallel to the ceiling.
3. The values are to be considered as indicative, as they may vary according to the type of ceiling, room dimensions and even the furniture used.
