pumps when installed in an enclosed area or where
required to pass air through a wall etc. Ensure the heat
pump is sealed against the wall so the outlet air cannot
recirculate. Ensure the hole through the wall is sealed
to avoid the outlet air entering cavities and is smooth
so the outlet air is not restricted.
