In this exchange, water is generated due to condensation forming as the warm outgoing air rapidly cools. It is essen-
tial that this water is properly drained away from the unit via the supplied condensate drain pipe.
ORKA has a 100% bypass that allows fresh air from outside to be introduced directly, without receiving the heat ener-
gy from the extraction air, generating free cooling. It is a manual activation.

New fresh air inlet:
This spigot is to connect the supply duct of fresh air from outside. Install the fresh air intake (wall or
roof) a suffi cient distance from any area of high pollution (trees, exhaust fumes, road, etc). To avoid
short-circuiting, the terminal should also be positioned a minimum of 1.5m from the discharge air
outlet.
This duct must be sealed and insulated to prevent condensation on the outside
and inside.
Supply fresh air into the building:
Connected to the air intake duct in the property. To avoid thermal losses, it is recommended to use
insulated ducts for the warmed air.
Extract air from the building:
Connected to the extract duct from the property. To avoid thermal losses and optimise the performan-
ce of the installation, it is recommended to use insulated ducts for the warm air.
