Connecting the refrigerant lines
Bby customer on-site connecting the refrigerant lines are at a corner of the unit within the false ceiling. It may
be necessary to fit a reducing or extending adapter to the indoor units. These fittings are included with the
indoor unit as an accessory kit. Once installed, the connections should be sealed to prevent vapour diffusion.
