1. Overview
LOOVENT eco fans are available in various versions which can all be fitted to a ceiling or wall in
either landscape or portrait orientation. The fan requires a suitable size hole through the wall or
ceiling which connects to a duct venting to the outside. The external opening (100mm round hole)
should be covered by a suitable grille, available separately from Airflow Developments Ltd.
LOOVENT eco Functionality:
Intermittent Ventilation
Timer - 17/31 l/s flow rate, boost triggered by integral pull cord
Humidity/Timer - 17/31 l/s flow rate, automatic boost triggered by humidity sensor – override
with integral pull cord
Motion Sensor/Timer - 17/31 l/s flow rate, boost triggered by an integral pull cord
Continuous Ventilation
dMEV T – 7/ 9/16 l/s flow rate, boost to 15/15/31 l/s triggered by remote switch /integral pull
cord.
dMEV HT – 7/ 9/16 l/s flow rate, boost to 15/15/31 l/s triggered by humidity sensor – override
with integral pull cord.
All models are two speed with a selectable 2 minute delay start function and a run-on timer
adjustable between 2 and 45 minutes. With the exception of the dMEV Fan, all fans can be
triggered remotely by means of a “switched live” connection from a light or door switch. The dMEV
model uses the “switched live” to initiate boost mode. All models feature a momentary pull-cord
switch as a manual “boost” override (no click will be heard when you pull this cord)
The fan has an ingress protection rating of IPx5 and is suitable for mounting in Zone 1 or 2 with a
30mA RCD as defined in Section 701 BS7161:2008 (IEEE Wiring Regulations, Seventeenth
Edition). The LOOVENT eco also complies with the latest Building Regulations, Approved
Document F (Part L).
LOOVENT eco requires a 100/240V-50/60Hz single phase supply. Class II equipment. BS EN
60417. An external 3A fuse is required for each fan unit. The product is fully compliant with the
following safety standards: CE2004/105//EMC Directives and LVD 2006 195/EC.
Note: Switches for fans should be selected and sited in accordance with BS7161:2008.
Do not place the fan near direct heat sources, e.g. radiant heaters, above cookers or where
temperatures can exceed 40°C (104°F).
All electrical installation 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. This fan is fitted with a safety device which inhibits operation when the front

Dimensions
Front Cover Removal
The front cover of the fan has a snap type fitting.
To remove, apply finger pressure to the two
semi-circular buttons at the edge of the cover
(Figure 5). This releases the cover from the body
of the fan allowing it to be pivoted. To remove the
cover completely, pivot it to 90° and lift away
(Figure 6).To refit, reverse the above procedure.
Fan Module Removal
Remove the accessories (fixing kit, adjustor tool,
anti-backdraught flap (or cone in the dMEV version))
from the body of the fan. The fan module is released
by undoing the two retaining screws alongside the fan
housing (Figure 7). Lift the left side of the module as viewed
slightly and slide to the right to release from the two lugs in the
base (Figure 7).
Recessing in the Wall
The fan can be mounted “landscape”, with the release
buttons facing downwards or “portrait” with the buttons on
the right hand edge. The fan requires a 110mm diameter
hole through the external wall lined with a 100mm internal
diameter duct kit (refer to Page 8 for accessories). The internal
wall requires a recess of 195 x 175 x 80mm deep. Important:
refer to the enclosed mounting template in the Box for location
of recess and fixing screws relative to the exhaust ducting.
Surface Mounting on the Wall
The fan can be mounted “landscape”, with the release
buttons facing downwards or “portrait” with the buttons on
the right hand edge. The fan requires a 110mm diameter
hole through the wall lined with a 100 mm internal diameter
duct kit (refer to Page 8 for accessories). Important: refer to
the enclosed mounting template the box for location of fixing
screws.
