Ventilation of Compartments
Where the appliance is installed in a cupboard or
compartment, air vents are required (for cooling
purposes) in the cupboard or compartment at high
and low level which may communicate with a room
or direct to outside air.
Detailed recommendations for air supply are given
in BS 5440: Part 2.
An existing cupboard or compartment may be used,
provided that it is modified for the purpose.
Recommendations for air supplies and details of
essential cupboard compartment design are given in
BS 5440: Part 2.
NOTE: Both air vents must communicate with the
same room or both be on the same wall to outside
air.
