4. External inlet and exhaust
- Mount Fresh Air inlet and Exhaust Air discharge
away from each other, so that cross contamination is not possible, and as suits
the home owner.
5. Internal return and supply -
Mount supply air grilles as suits the homeowner,
eg in the hallway and living areas. A hinged filter grille (eg PYHF400) can be
used for return air. Mount return air grilles as suits the homeowner, eg one in
the bathroom and one at the other end of the hall from supply grille.
6. Filters
inside unit are secondary filters. Mount hinged filter grilles (eg
PYHF400) or extended surface filters (eg FBP200) in ducting prior to unit for
return air from house as well as fresh intake air.
3. Drain installation
Drain adaptor (supplied inside HEX filter
cover) is to be mounted to bottom of
HEX unit. HEX unit must be level.
Condensate drain hose
needs to be connected
and shaped into a “P
trap”, as in diagram:
7. Duct
Attach insulated ducting to all spigots and Y branches securely, ensuring
an airtight seal by using tape. Duct runs must be stretched and as straight as
possible, with long radius bends to minimise airflow resistance. Ducting must
be supported separately from the HEX unit. Ducts must be insulated.
