3.2.1 Dirty Filter Pressure Switch Wiring
The cable gland is designed for cables with alternative sheath diameters
of 8 - 10 mm. Only use these sizes, otherwise the screw cable
connection cannot seal adequately. The connections are intended for
6.3mm crimp-type sockets.
•
Remove switch cover.
•
Wire the main unit to the terminal block within the switch as per
the below wiring diagrams (Figure 12) ensuring the feed line is
fused to suit Max 1.5A / 250 Vac.
3.1.2 Attaching XBC Flange
To aid in installation where IAQM units are to be close coupled to a
matching size XBC unit, the double (Supply & Extract) flange connector
of the XBC unit should be removed from the XBC and fitted to the
IAQM unit’s inlet along with the extract leg ducting. The full assembly
of IAQM unit, XBC flange connector and extract ducting can then be
raised and connected to the XBC unit. For further details see "Flange
Connector Dimensions (mm)" section, located in XBC+ installation
manual provided with XBC+ units.

3.1.3 Rolling IAQM Unit
If a side access IAQM unit is to be close coupled to a right hand
configuration XBC unit, roll the IAQM unit 180° to ensure XBC ducting
paths are clear.
Where a roof is supplied with the IAQM the roof should be removed
by unscrewing the 4x roof mounting points (2x M8 hex bolts) before
rolling the unit and reattaching the roof using the same 4 roof
mounting points.
Where an IAQM has no roof, the 4x mounting brackets provided can
be also be removed (2x M8 hex bolts) and reattached according to the
required mounting method if needed.

Handling IAQM Unit
3.1.4 Relocating IAQM Roof
Due to the XBC roof overhang, an IAQM with roof cannot be close
coupled to an XBC unit with roof without relocating the IAQM roof
prior to installation.
Unscrew the M8 hex bolts attaching the IAQM roof to the 1st and 2nd
roof fixing points. Slide the IAQM roof away from the IAQM inlet and
utilize the 2nd and 3rd roof fixing point to reattach the IAQM roof.
