7 Preparation for installation
Installation information
• PP 45 units are only suited for supply air rooms.
• PPB 30 units are the ideal choice for exhaust
air rooms.
• Observe minimum spacing.
• Ensure sufficient space to work in front of the
unit → filter change.
• The customer should provide appropriate
mounting material for mounting the wall sleeve
and external cover.
• Core hole diameter DN 162. To ensure that
condensate is removed via the external cover,
the core drill hole should have a 1 to 2 % incline
to the exterior wall. The condensate is drained
via the external cover. Recommendation: To
prevent dirt from depositing on the façade
around the external cover, fit a water-repellent
plaster system.
• Wall thickness PP 45, min. 265 mm.
• Wall thickness PPB 30, min. 320 mm.
• PPB 30: The slide-in unit (slide-in module + ex-
tension duct) must be appropriate for the wall
thickness, to avoid a ventilation short-circuit
(lack of air). To ensure this, shorten the exten-
sion duct accurately.
• PPB 30: With wall thicknesses of 500 to 790
mm, use the optional PP 45 VS extension kit.
When installing, use the centring ring provided
for the extension.
• Observe permissible ranges for radio-controlled
units → Technical data PP 45.
• Select installation position so as to avoid con-
tamination and draughts.
• Only connect PP 45 O units to PP 45 LT power
units.
• In case of thin walls, use the compensating
frame PPB 30 ARE (stainless steel) or PPB 30
ARW (white). This can be screwed to the wall
with the fixing plate PPB 30 ARE BB or PPB 30
ARW BB. Compensating frames (depth 55 mm)
are stackable. Only use stainless steel screws
when installing stainless steel compensating
frame covers.
• The ventilation units and controls are not suit-
able for use in protection zones → Danger of
electric shock in the event of moisture ingress.
• RLS-/DS Only use controls outside protective
zones 0, 1 and 2.
• Use PP 45 ventilation units only outside pro-
tections zones 0, 1 and 2.
