This user’s guide is meant for the installer and if necessary
for the user. It’s a reference to operaon and installaon
of the SD-EC destracaon fan. For the sake of safety
and to guarantee proper funcon, it is vital that you read
this manual thoroughly before starng the installaon, in-
cluding all ps and warnings.
Keep this manual with the appliance and see to it that it is
included when the appliance is moved or sold, to ensure
that during its life, all persons have been informed about
the use and safety aspects of the device.

The SD-EC destracaon fan consists of a metal casing
with a bladed fan & motor ed within a fan guard. There
is an outlet grille with adjustable louvers on the oppo-
site side, which enables the airow to be directed in the
desired direcon. A ed thermostat allows automac
operaon.

The SD-EC destracaon fan is designed to be ed
within the roof space of a building to recirculate e soluon
to achieving this is by ng destracaon fans. These
fans recirculate the, otherwise wasted, warm air gather-
ing within the roof space, to low level. The ed thermo-
stat (SD models) automates this process.
i.e If the room thermostat is set at 25°C, it will switch the
fan on as soon as this temperature is achieved at ceiling/
roof level. The fan will stop when the thermostat detects
a reducon in temperature of approx 1.5°C.
The fan speed can be controlled by:
• 0-10V regulator GA3955
• External power source (0-10V d.c.)
The installaon of a correctly sized destracaon
system, pays for itself quickly due to the signicant energy
savings achieved

The unit has been applied with 4 suspension eyes for use
with chains or steel wire (not included). Ensure the appli-
ance has an uninterrupted supply of air on both inlet &
outlet, a minimum clearance around the air inlet of 0.5m
should be observed. For exact distance for each specic
unit consult the technical data.

A rule of thumb, choose one fan per 300m2 oor surface.
A more accurate method is on basis of circulaon short-
age.
This is easy to calculate:
Calculate the volume of the space in m3, mulply this by 2.
The resulng gure is the volume in m3/h needed by the
SD-EC destracaon fans.
Select the SD-EC model based upon air output, throw of
the unit and height of the room. Then simply take the ca-
lulated air volume and divide by the air volume produced
by your selected SD-EC model. The resulng gure is the
qty needed for your applicaon.
Selecng an SD-EC model with the highest air vol-
ume is not nessecarily the best soluon. It is important
to achieve uniform air distribuon throughout the space,
for maximum comfort and reduced running costs.
Occasionally it will be nessecary to install more SD-EC
fans that calculaons indicate to achieve uniform air dis-
tribuon. In these scenarios, where possible, reduce the
model size and increase the quanty.
Always ensure the model of fan is capable
of being installed at the height you propose.

Posion the destracaon fan preferably towards the
end of the throw or area that is not directly served by the
heaters throw.
In general, a higher number of fans provides beer air dis-
tribuon.
We suggest that one fan is used per 150 to 300m2 square
of oor surface, taking into account mounng height and
model.
Each SD-EC fan should be ed approx. 1.0m beneath the
roof or ceiling, but not closer than 0.35m. The distance
between oor and fan may not exceed the length of the
fan’s throw as this will prevent the warm air from reaching
the low level. Ensure that the fan is not mounted lower
than the minimum throw to avoid dras and oor dust
from being disturbed.
Even with the louvres set at maximum deecon, there
will be a severe dra when the unit is suspended too low.
Do not place the SD-EC fans above plant machinery or
high obstacles.

Power supply to this appliance must be made by wiring
into the terminals within the fan motor. See diagrams in
chapter 6.
The installaon must comply with all applicable local and/
or naonal standards i.e. NEN 1010.
There should be a suitable electrical circuit with a main
fuse. There is an electrical diagram further on in this guide.
The power supply is 230Vac (50 Hz) with earth.
The fan must to be equipped with a 230Volt isolaon
switch or power plug. This switch should disconnect phase
and neutral (not earth) and have a 3mm contact opening
at least. Switches or power plugs must be accessible at all
mes.

The SD-EC is equipped with an on/o thermostat. This
thermostat is connected with the 0-10V control of the
motor. The thermostat measures the temperature near
the fan and switches on the motor when the set temper-
ature has been reached. For correct seng of tempera-
tures, see paragraph 5.1
Besides seng the temperature, the fan speed has to be
set. This van be done in the following ways:
1. Maximum speed only
2. Speed regulator
3. External via 0-10V d.c.

The maximum speed can be set by installing a wire be-

On contacts [T1], [T2] and [S3] of the 6-pole connector,
the oponal speed regulator GA3955, or a 3 wire poten-

Aenon The SD-EC needs 2 signals in order to run.
The thermostat contact on the WCU has to be closed and
the speed seng has to be made. If one of these signals is
missing, the motor will not run.

The SD does not need manual control, it is automac.
Generally temperature seng has to be done by
the installer. The user is allowed to do following sengs:
• Set the temperature at which the fan should ven-
late.
• Turn ON/OFF main switch
• Change fan speed by adjusng the speed regulator
Aenon: Do not set the louvres at an angle greater
than 20°. This will reduce the air volume and in turn the
throw.

In areas where heavy dust is present, it may be necessary
to clean the fan & guard with compressed air once a year.
If the guard is covered with severe dust, the fan will not
provide opmal performance.
Check if the appliance turns ON and OFF as it should on
the thermostat.
Pay aenon on:
• The ON and OFF switching from the thermostat
• The smooth rotaon of the fan
• Remove the dust from the appliance
• Check that the fan does not have severe vibraon

If more than one SD-EC needs to be connected to one speed controller, please make sure that the 10V supply of the
dierent units are NOT connected to each other. All SD-EC’s must get their 0-10V supply (10V out, T2) from one
SD-EC. See SD-EC 1, on the diagram below.

Diagram 6 Several WCUs controlled by 1 speed regulator
If more than one WCU needs to be connected to one speed regulator, please make sure that the 10V supply of the
different units are NOT connected to each other. So all WCUs get their 0-10V supply (10V out, T2) from one WCU. In
the diagram below this is WCU No. 1.
