About 80 cm/32” clearance should be left in front of the unit to provide unimpeded access to the cubicle. Local or general
safety regulations, e.g. escape routes, should also be observed. In no circumstances must the air inlet (around the bottom of
the unit) and the air outlet (around the top of the unit) be covered or obstructed.
