Installation Instructions

2.1

General Preparation

2.1.1 The CMEV.4e range of units are supplied with 5 x 125mm ducting spigots for connection of ducts to the unit for
installation and 2 x blanking caps to close or block off unused spigots. One inlet spigot is located under the
base of the unit and is supplied blanked off. For installations requiring fifth inlet port, proceed to cut out the
spigot blank and connect duct. (See Figure 1).
2.1.2 125mm duct should be used to provide the best performance levels required for compliance with building
regulations. The CMEV.4e range has been tested with both 125mm and 100mm round ducting. Note;
Reducing ductwork to 100mm will increase system resistance and affect overall specific fan power ratings.
Technical Services can be contacted on +44 (0) 1276 408402 should you have any questions in respect of this.
2.1.3 Installation of the unit should be in accordance with the current editions of Building Regulations and
BS7671: IEE Wiring Regulations.
2.1.4 The design, material specification and installation must only be carried out by 'competent persons'. Electrical
installation must be carried out by a qualified Electrician.
2.1.5 Ducting must be installed as per the Domestic Ventilation Compliance Guide 2010 and insulation must be
