Installation
The HR500IP unit should be set in an inner wall with the grille flange set flush with the
inner surface (a steel lintel is provided for additional support of the building fabric if
required). If used this will automatically produce a 3° slope of the unit away from the inner
grille for drainage of any condensate which may form during operation.
A 22mm drain is situated between inlet and exhaust spigots and should be connected to a
suitable drain/soakaway.
