ECO dMEV LC Centrifugal Extractor

Fans

The ECO dMEV LC extractor fan range

is manufactured to the highest stan-

dards of production and quality as

laid down by the international Quality

Standard ISO 9001. All components

have been checked and every one of

the ﬁnal products will have been in-

dividually tested at the end of the ma-

nufacturing process.

On receipt of the product we recom-

mend that you to check the following:

1. That it is the correct model.

2. That the details on the rating label

are those you require: voltage, fre-

quency... The installation must be

carried out in accordance with the

electrical standards in force in your

country.

This appliance can be

used by children aged

from 8 years and abo-

ve and persons with

reduced physical, sen-

sory or mental capabi-

lities or lack of expe-

rience and knowledge

if they have been given

supervision or instruc-

tion concerning use of

the appliance in a safe

way and understand

the hazards involved.

Children shall not

play with the applian-

ce. Cleaning and user

maintenance shall not

be made by children

without supervision.

INSTALLATION

IMPORTANT: Before installing and

wiring the unit, ensure that the main

supply is disconnected.

Fig. 1b:

1. Front grille

2. Protection cover

3. Support

4. Connection terminals

5. Cable entry

6. Dip switches

7. Potentiometer for speed adjustment

8. Air ﬁlter

The ECO dMEV LC is suitable for wall

or ceiling mounting and can either ex-

tract directly to the outside or via an

individual ducting system (see Fig. 2).

Make a hole in the wall or ceiling of

diameter 105 mm.

If the unit is to be installed with indi-

vidual ducting, use a standard duct of

diameter 100 mm.

Remove the front grille (1) and the

protection cover (2).

The unit can be mounted on the wall

or ceiling using the 4 plastic plugs

and the screws provided.

Ensure that there are no obstructions

to the airﬂow and that the impeller

turns freely.

Introduce the mains cable through the

cable entry (5) and ﬁx it to the wall.

Connect the electrical wiring as set

out below and then mount the protec-

tion cover and the front grille.

ELECTRICAL CONNECTION

The ECO dMEV LC is an extractor de-

signed for a single phase supply, with

voltage and frequency as indicated on

the rating plate of the unit. The units

are manufactured with double electri-

cal insulation (Class II) and therefore

they do not need an earth connection.

The electrical installation must inclu-

de a double pole switch with a contact

clearance of at least 3 mm.

The electrical cable must enter the

ECO dMEV LC through the cable en-

try (5).

Once the cable has been introduced

proceed using the electrical wiring

diagram applicable to the selected

model.

OPERATION

The ECO dMEV LC is an extractor fan

designed to operate continuously at

low speed (adjustable) with the facility

to be set to high speed (ﬁxed) through

the following functions depending on

the version: an external switch live or

light switch (S, T and HT versions);

the humidity sensor (HT and HTP ver-

sions); the internal pull cord switch

(HTP version); or the PIR detector (DT

version).

The extractor can also be used for in-

termittent operation with adjustable

speed at installation.

In both cases the speed setting is

done when installing the extractor,

with the potentiometer (7) placed on

the electronic PCB (ﬁg.1b).

Please commission the fan at 9l/s or

above to meet SAP requirements.

The selection between continuous

operation and intermittent operation

is done with the dip-switch 9:

Continuous operation: ON

Intermittent operation: OFF

ATTENTION: In intermittent opera-

tion, mount the backdraft shutter on

the fan outlet.

ECO DMEV S LC

1. Continuous operation only on tric-

kle setting (Fig. 3).

Once the air volume is set the fan

is connected to the mains and the

unit will operate continuously at

this air volume.

2. Continuous operation on trickle

with ability to boost at high speed.

The ECO dMEV S LC is connected to

an external switch or light switch.

When the switch is closed, the fan

runs at full speed until the switch

opens again (light off):

Fig.4a- Wiring diagram to boost the

fan with the light switch.

Fig.4b- Wiring diagram to boost

the fan with a separate switch

3. Intermittent operation: With dip-

switch 9 set to OFF the extractor

runs at the preset speed when the

switch is closed:

Fig.4a- Wiring diagram to switch

on the fan with the light switch.

Fig.4b- Wiring diagram to switch

on the fan with a separate switch.

Start-up timer function:

In this operation, the “start-up ti-

mer function” allows you to delay

the extractor start-up for a period

of 50 seconds. So that, for exam-

ple, the fan does not switch on if

the usage time of the bathroom is

less than 50s.

If you exceed the 50s, the fan swit-

ches on, and when the light swit-

ches off, runs the time set by the

timer.

This function is selected with the

dip- switch 8.

ECO DMEV T LC

This model is provided with an adjus-

table over-run timer.

The selection of the run on time is

done with the dip-switches 6 and 7:

setting between 1, 5, 15 and 30 mi-

nutes

Factory setting: 1 minute

1. Continuous operation: The timer

allows the fan to continue to ope-

rate in high speed for the selected

period after the switch has been

turned off.

Fig.4a- Wiring diagram to boost the

fan with the light switch.

Fig.4b- Wiring diagram to boost

the fan with a separate switch

2. Intermittent operation: The timer

allows the fan to continue to opera-

te for the selected period after the

switch has been turned off (ﬁg.4a

and 4b).

Start-up timer function:

In this operation, the “start-up timer

function” allows the fan to delay the

start-up for a period of 50 seconds.

So that, for example, the fan does

not switch on if the usage time of the

bathroom is less than 50s.

If you exceed the 50s, the fan swit-

ches on, and when the light swit-

ches off, runs on for the time set by

the timer.

This function is selected with the

dip- switch 8.

ECO DMEV HT LC

Models provided with an electronic

humidity sensor which can be adjus-

ted from 60% to 90 % RH (relative
