Duct installation
1. Side openings are provided for installing separate ducts for outside air intake and treated air distribution to an adjacent
room.
2. Use a punch to remove the knock-down openings on the casing. Use a knife to make the suitable opening on the
polystyrene behind the casing.
TAKE CARE not to damage the heat exchanger coil located behind the openings.
3. Plug the gaps between the ducts and the opening edge with anti-condensation insulation.
4. Use material which can withstand a continuous operating temperature of 60. The ducts can be of the flexible type
with a spring core or of corrugated aluminium, covered inside with an insulating material (12 to 25 mm thick glass
fiber).
5. When the installation is finished, all the surfaces of the non-insulated ducts must be covered with anti-condensation
insulation material (6mm thick expanded polystyrene or expanded neoprene). Fire proofing classification: M1.
6. Distributing air to an adjacent room requires the corresponding panel air outlets to be sealed by using the sealing
material (Accessory)
7. A decoration grille must be fitted in the partition between the air conditioned room (where the cassette is installed)
and the adjacent room.
