are disconnected. Never run the with the MVHR heat exchange core

household vacuum cleaner. Do not attempt to clean the heat
exchanger with any fluids.
Step 7
. Carefully re-insert the heat exchanger and the foam panels
into the unit.
Step 8
. Place the back panel on the unit so that the 4 holes line up
with the threaded inserts and then place the bracket over the back
panel again lining up the holes.
Step 9
. Securely fit the 4 bracket fixings.
Step 10
