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
