IMPORTANT

If multiple units are installed in an enclosed area then the inlet free areas

required for each unit can be added together to form one inlet aperture.

BUT discharge from each unit must be kept separate and must not be

incorporated into one common duct system.

Due consideration must be given to air flow i.e. do not obstruct inlet or outlet

and ensure discharge to air cannot recirculate to inlet. (See below).

Required Free Areas to provide air flow to and

from heat pumps when installed in an

enclosed area or where required to pass air

through a wall etc.

Free areas is the available area through which

air can pass through a grille or louvres.
