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

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.
