5.2 Impact noise reduction
With installation on wooden floors or other vibration-prone components, there may be a combined impact noise (use
rubber mounting feet).
5.3 Wall mounting the MVHR
There is a metal bracket fixed to the rear of the metal casing for mounting the MVHR on the wall. The corresponding
metal wall bracket, which is to be fixed to the wall, is supplied (without fixing screws) in the product packaging.
Mark out the fixing holes for the wall bracket and drill the holes to suit the fixing screws to be used.
Precisely align the bracket on the wall using a spirit level and fix the bracket to the wall with suitable fixing
screws.
Fix the two self-adhesive rubber feet supplied to the rear bottom corners of the MVHR.
Lift the MVHR up to the wall and hang onto the bracket on the wall. Ensure the MVHR is positioned centrally
to the bracket fixed to the wall.
5.4 Heat exchanger retaining bracket
Once the MVHR has been mounted in the right or left-handed orientation, the Heat Exchanger Retaining Bracket
supplied (see picture below) must be fitted to the front of the MVHR as follows:
Remove the Access Hatch on the front of the MVHR by turning it to the left.
Fit the Retaining Bracket and retaining screw supplied with the MVHR.
Replace the Access Hatch by turning it to the right.
Important: The Heat Exchanger must only be removed for cleaning.
Before removing the Heat Exchanger disconnect the MVHR from
the mains supply.
5.5 Ducting
Flexible ducting should only be used for final connections with special care taken to avoid restrictions and other
conditions which will restrict air flow.
When installing ducting, care should be taken to ensure it is properly supported and secure with joints properly
sealed. All ducting located in loft spaces and roof voids etc., which are unheated, must be insulated, together with the
duct runs from the unit to atmosphere.
All ducting fitted to the spigots on the MVHR should be secured in place with jubilee clips or a suitably sized plastic
cable tie.
