2 AIR FLOW
Due consideration must be given to air flow, i.e. do not obstruct inlet or
outlet and ensure discharge air cannot re-circulate to inlet. (See figures 1
and 2).
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 area is the available area through which air can pass through a grille or
louvres.
Note: 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.
Note: ON AW1834BHC ducting must not be fitted directly to the unit. Inlet
duct spigots are available to order.
