3.1 Ducting Guidelines

Please refer to the dwelling's design drawings for the proposed ducting

layout.

Two 220mm x 90mm sockets are provided for connecting the ducting.

Domus rigid ductwork should be securely connected to the sockets

using DDSEAL acrylic sealant; failure to do this will cause unnecessary

air leakage and impair performance. Using the arrows moulded into

the body of the CMX-S appliance as a guide, ensure that the

direction of airflow is from the 'wet rooms' to the outside.

Ducting attached to the appliance must be supported adjacent to

the appliance using 922 Support clips. This is important for major

maintenance or end of life replacement to ensure that the ducting is

adequately supported if the CMX-S body is removed.

Where ducting passes through unheated areas and voids (e.g. loft

spaces) it must be insulated in order to comply with Approved

Document F of The Building Regulations.

When passing through a fire-stopping wall or fire-compartment wall,

FireBrake intumescent duct connectors should be used in order to

comply with Approved Document B of The Building Regulations.

Alternative proprietary fire-stopping methods may be employed

provided they comply with Approved Document B of The Building

Regulations.

The stale extract air must be expelled to the exterior of the property.

If expelled through a wall, a 905 airbrick should be fitted. If expelled

through the roof a 4411 universal roof terminal should be fitted or a

proprietary roof terminal designed for mechanical ventilation with a free

area of at least 15175mm².

Further details regarding installation can be found in the 2010 Domestic

Ventilation Compliance Guide.

3.1.1 Rigid Ducting

Install using the least number of fittings to minimise resistance to

airflow. All duct runs should be as short and as straight as possible for

maximum performance.

3.1.2 Semi-Rigid (Radial) Ducting

4.0 ELECTRICAL

WARNING: This appliance must be earthed.

All wiring must be carried out by a qualified electrician and

conform to the prevailing national regulations, for example the

latest edition of BS7671: IEE Wiring Regulations.

This appliance is suitable for 230V 50Hz single phase supply only, fused

at 3 Amps. A double-pole switch having a minimum contact separation

of 3mm must be used to provide isolation for the appliance.

Sensor diagrams are shown on page 9. External wiring (1.5mm² max.)

and isolators to be supplied by others.
