It is recommended these units are installed by a preferred installer, please

All electrical connections are subject to NZ law.

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 (if supplied) 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

must be installed vertically, with the pack glands downwards. The attic

controller can be fixed to the timber framing in the roof space.

Hall Controller

Hall controller is to be installed in the house at least 3m from the

diffuser but in the same area, approx. 1.5m above the floor. The hall controller

should not be installed on an external wall, in a living / dining area or in the

immediate vicinity of a heater or heat pump outlet. This is so that the Hall

Controller's built in temperature sensor is not affected by outside air temperature

or heating, and should best measure average house temperatures.

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.

Installation Procedure

Based on the above criteria:

1. Fit Diffuser

Before cutting hole for diffuser, check that it will clear ceiling

joists and roof structure. Use circle template to cut correct sized hole in the

ceiling. Attach duct to grille, taping the centre duct sleeve to the grille spigot

then separately taping the insulation/outer to the spigot. Feed ducting through

the hole and clip diffuser in place using the spring clips. Ensure grille has a

minimum gap of 16mm between inner disk and outer collar.
