Note: 'SPLASH ZONE'

room or shower room where a person using the bath or show-

from the edge of the bath or shower up to a height of 2.25
metres.
a) An opening should be prepared to accept the fan case
plus a clearance of 5 - 10mm which will be necessary to
allow for the fixing brackets.
327mm x 245mm will be required. Care must be taken
during this operation as an aperture larger than 335mm
x 253mm will not be covered by the front panel skirt.
