Installation
5.5.1
Wall-mounting the MVHR
For wall-mounting the MVHR, three wall-mounting
brackets are supplied.
Mark out the fixing holes for the wall-mounting
brackets using the diagram provided and drill
the holes to suit the fixing screws to be used.
Precisely align the three wall-mounting brackets
on the wall using a spirit level and fix the three
wall-mounting brackets to the wall with suitable
fixing screws.
Remove two screws from the top of the MVHR
which align with the holes in the top wall-
mounted bracket. Remove the four screws from
the bottom of the MVHR which align with the
slots in the two bottom wall-mounted brackets.
Place the MVHR on the three wall-mounted
brackets and fix in place by re-fitting the six
screws previously removed.
5.5.2
Installation of the ducting
When installing ducting, care should be taken to
ensure it is properly supported and secure with
joints properly sealed. Flexible ducting should only
be used for final connections with special care
taken to avoid restrictions and other conditions
which will restrict air flow.
5.6
Condensate drain
A condensate drain must be fitted to run to the
building waste water system in accordance with the
Building Regulation H1.
The condensate drain tube is connected to the
MVHR through the hole on the underside of the
plastic base. The condensate drain tube can be
adapted to the installation requirements. It is impor-
tant that the drain tube is positioned higher than the
water surface of the water trap and that the drain
tube ends within the water head of the water trap.
The condensate drain tube should be checked an-
nually and cleaned if necessary. A condensate
drain tube (Ø 20mm and 1.0m long) is supplied with
each MVHR. The water trap must be purchased
separately from a local plumbing stockist.
