Aircommand Heron Q Manual de instrucciones de instalación
Fitting of the 3 return air grilles/filters
Provided the cupboard is 540mm wide or more,
the three grilles can be installed side by side in
the underside of the cupboard. (Refer fig. 7)
In the case of pop top vans, it may be convenient
to install one of the three through the top. Make
sure however, that all three are installed.
Place the grilles as far back as is possible to
allow the most direct route of the air to the fan
inlet.
Cut out size for each grille is 158 x 232.
The following describes the procedure for both a
cupboard with a removable front, and a cupboard
with a front that is not easily disassembled.
Typically the latter type will have 4 to 5mm ply
which will need reinforcing around the perimeter
of the cutout and tying to the main structural
members of the cupboard assy.
Make out the cut out as per fig 6a.
Drill holes at the corners of the cutout to allow a
jig saw to cut out the entire cutaway.
It is important to cut the hole out accurately.
If the front panel is a solid 19mm panel, the
A/H will not need additional support. If
however the front panel is light ply, then this
must be strengthened after cutting out as per
the template. This framing should be 20mm
thick to provide the necessary support, and
should tie in with the main cupboard
members, to support the weight of the
Airhandler.
The front panel can now be fitted and screwed
into place.
Installation of the refrigeration pipe
work and condensate drain
The 9.4mm Ø and the 6.4 Ø pipes can enter
either side of the cupboard, and be carefully
manipulated to make the connection to the
Airhandler. The 9.4 Ø pipe must be insulated
entirely.
The condensate drain is normally run vertically.
12mm hose or poly pipe is preferred. An elbow
is provided in the installation kit to change
direction from the vertical run to the horizontal
to connect the airhandler. Failure to use this
elbow usually results in a hump in the drain
which may impede drainage, or a kink.
