Pre-Installation checks
Before starting the installation, check the site & establish the best position/s of
the following components:
Diffuser
For most small to medium sized homes a single diffuser is usually all that
is necessary. It is recommended this be installed into a hallway that is common
to most rooms in the home. Installation of the main diffuser into the living /
dining area is not recommended.
Unit
The Unit comprises of the Fan, Heater (for DM07B) and Filter box. It is
important to install the Unit so that it is as high as possible in the roof space,
this is to maximize the benefit of any thermal gain. It also keeps the fan inlet
air above dust which may come from the roof insulation. IMPORTANT: The
unit must be installed in a perfectly horizontal position to ensure correct heater
operation.
Attic Controller
Is to be installed at the same level as the inlet to the fan, so as to
best measure the inlet air condition (temperature) of the unit. The attic controller
should be installed vertically, with the pack glands downwards.
The attic
controller can be fixed to the timber framing in the roof space.
Ducting
Installation of ducting should allow for a full stretch and a smooth sweep
onto the rear of the diffuser. This will have a marked effect on the effective
operation of the unit air flow & attenuation of fan noise.
