Anti-Back draught Flap
All models (with the exception of dMEV model)
Are supplied with an anti-back draught flap
accessory as shown in Figure 14. If required, this
assembly may be fitted to the spigot of the fan as
shown in Figure 15. Note: the hinge of the flap
must always be vertical as in Figure 15 for
correct operation. This accessory is not
recommended for ceiling mounted applications.
Use of the flap will cause a slight reduction to the
rated output of the fan. An external gravity flap
grille may be used if required. (optional

Airflow Part #51791101)
Restrictor Cone
The Continuous Ventilation dMEV model is
Supplied with a restrictor cone to increase the
air velocity. This is supplied as a two part
assembly (Figure 16) and should be clipped
together and secured with adhesive tape (not
included) to the spigot of the fan (Figure 17) The
cone is only required in applications requiring a
continuous trickle ventilation rate of 7/9 l/s
–WC,
En-Suite, Bathroom and Utility. (Normal 100mm
ducting should still be connected to the fan
spigot and not the cone outlet) The cone is not
required for operation at 16 l/s.
3. Electrical Installation
All electrical installations should be carried out by an approved electrician in accordance with Part
“P” U.K. Building Regulations and to the latest IEEE standards, or the appropriate regulations in the
country of installation. The LOOVENT eco requires a 100-240V 50/60Hz supply and an external 3A
fuse; it is double insulated so therefore does not require an earth. For fans mounted in Zones 1 & 2
as defined in section 701 BS7161:2008 additional protection must be provided by a Residual
Current Detector (RCD) with a rated residual operating current not exceeding 30mA. An isolator
switch should also be installed in the MAINS input line to facilitate maintenance and cleaning of the
fan.
Power connections are made through the terminal block as shown in Figure 18. Unplug the terminal
block from the base of the fan module. Prepare the cable by leaving a length of 60mm protruding
from inside the base of the fan. Strip the conductor insulation back by 5mm and connect to the
terminal block as shown in Figure 20 or 22 on Page 6. Once connections have been made, feed
the cable back into the recess and clip the terminal block back into location as shown in Figure 19.
The power connection is made automatically when the fan module (see Figure 1) is positioned into
the unit and the two M4 retaining screws (see Figure 7) are tightened.
