1 IDENTIFICATION
This overview contains general information about the device. The purpose of this part is to indicate the
limits and overall operation of the device, and the areas it is used in.
1.1 General
1.1.1 Description of the device
The Enfan consists of a fan mounted vertically on a lattice shelf using suspension brackets and
mounting brackets. Various accessories are available, such as an inflow/outflow grid and power cord
with plug, where the latter depends on the type of fan. It is also possible to order an outflow guide flap
so that air is expelled in a certain direction.
There are no controls on the Enfan itself.

1.2 Users
Generally, the Enfan is not operated directly, but controlled by an operator or user via a control box.
These users or operators must be at least 18 years old, employed by the company where the Enfan is
installed, and designated by the management as competent and authorized to operate the Enfan.
All those who do not meet the above definition are unauthorized users, and these unauthorized users
may create unsafe situations or risks to themselves or others if they use the device.
1.3 Use
The Enfan is designed to circulate air horizontally in a greenhouse to improve the climate distribution.
The Enfan is not designed to be used for any other purposes than those described above, such as
transporting gases other than low-temperature air (-10 °C to + 50 °C).
1.4 Authorized servicers
The Enfan can be serviced by any maintenance company, but Van Der Ende is recommended as this
company is familiar with every aspect of the device.
Periodic servicing helps avoid unnecessary costs or failures, and improves reliability.
1.5 Operating environment
Install the Enfan on the lowest beam of the lattice shelf in the greenhouse. using suspension brackets
supplied by Van der Ende. It must not be possible to touch the ventilator without special equipment,
and the shelf must be in good enough condition to bear the fan.
The Enfan is not designed for use in any other environment than that described above, except for
customer-specific requests under the guidance of Van der Ende. The Enfan is not suitable for use in
explosive environments.
1.6 Guarantee conditions
The unit is guaranteed for 6 months after first use.
If a claim is made under guarantee, the parts concerned must be presented to the manufacturer for
assessment.
The guarantee is void in the event of any of the following;
•Improper use
•Ignoring the manufacturer’s or supplier’s advice
•Unauthorized repair, maintenance or use
•Use of inappropriate power supply connections
•Use of the machine in an unsuitable environment
•Intentional damage or modification of the machine
1.7 Relevant directives
The Enfan complies with the provisions in the following directives wich can be found in attachments.
The Enfan is classified as a Class I device according to the Low Voltage Directive.

2 DESCRIPTION
2.1 General
The purpose and function of the Enfan is to create horizontal airflows in greenhouses. External
influences create unwanted natural drafts in greenhouses, which result in fluctuations in temperature
and humidity. Using the Enfan to create airflows in a greenhouse reduces these variations in
temperature and humidity. The airflow has a beneficial effect on growth, maturation and resistance to
fungal diseases.
The Enfan can be used where all kinds of vegetable, fruit and ornamental plants are cultivated.
2.2 Delivery
As standard, the Enfan is supplied without mounting brackets or other accessories. The various parts
are supplied in separate packs, and can be assembled on site.
3 SAFETY INSTRUCTIONS
When working on the Enfan, always make sure the plug is disconnected from the power supply! This
prevents the fan starting unexpectedly or unintentionally.
Only use self-locking nuts to mount the Enfan. Failure to do so may result in parts vibrating loose and
falling off.
The regulations below are applicable to the Enfan.

4.5 Air flow guide plates
Air flow guide plates direct the air that is blown from the ventilator. Various configurations are possible
to control the air flow. The configurations presented in chapter 4.5.1 are tested by VDEG on their desired
effect. However, due to differences in installations, it is recommended to perform a single test prior to
implementation, in order to obtain the most desirable effect.
4.5.1 Configuration of the air flow guide plates
The number of guide plates attached to the Enfan and their orientation are vital for determining the air
flow. The configurations with one guide plate are shown in Figure 12. The left configuration restricts
the airflow downwards whilst the right restricts the flow upwards. A downwards restriction might be
necessary if the airflow affects the crop too much. An upwards air flow restriction is imposed when the
flow affects the screen cloth too much.
Figure 12 Downward (left) and upward (right) air flow restriction
If the configurations in Figure 12 do not influence the air flow enough, one can choose to use two air
flow guide plates to restrict the flow. Figure 13 shows these configurations. The left configuration is used
to limit the downward air flow even more. Respectively, the right configuration limits the upward flow
even more than the one in Figure 16 does.
Figure 13 Extra downward (left) and upward (right) air flow restriction

Page 18 of 32
4.5.2 Assembling the air flow guide plates
To attach the guide plates to the Enfan, the
mounting bracket must first be attached to
the fan. One can also choose to attach the
guide plates to the mounting bracket before
connecting the bracket to the Enfan.
Requirements:
•1x mounting bracket
•4x hexagonal tap bolt m10 x 25
•8 x washer m10
•4x lock nut m10
The mounting bracket will be connected to the fan according to Figure 14. Depending on the
configuration, the bolts passing through horizontal strip of the mounting bracket will fixate either one or
two air flow guide plates.
Requirements:
•1x Air flow guide plate
•3x hexagonal tap bolt m5 x 16
•6x washer m5
•3x lock nut m5
When one air flow guide plate is connected to the mounting bracket, Figure 15 shows how it needs to
be assembled .
Figure 15 Connecting one air flow guide plate to mounting bracket
Figure 14 Mounting bracket for guide plates

Page 19 of 32
If two guide plates are used to restrict the air flow, Figure 16 shows how they are connected to the
mounting bracket.
Requirements:
•2x Air flow guide plate
•4x hexagonal tap bolt m5 x 16
•8x washer m5
•4x lock nut m5
Figure 16 Connecting two air flow guide plate to mounting bracket
The Enfan comes with an outlet grill which can be mounted in front of the fan outlet by means of four
torx screws.
Whenever air flow guides plates are used in combination with the outlet grill, the plates need to
mounted in reversed position. The guide plates should be attached to the outlet grill with Ty-raps.

5 CONNECTING THE THERMOSTATIC SWITCH
A thermostatic switch is built in to the winding of every fan as standard. When connected, this switch
turns the motor off if voltage levels are exceeded and the internal temperature rises above 100 °C.
The motor gets too hot if the fan becomes blocked, or similar.
Connecting the fan in this way increases its life span. Connect the fan as shown in Figure 17 and 18.
The thermostatic switch is connected in series with the phase. The red line in Figure 17-18 is the
connection between TB and U1.
The FN035 thermostatic switch is NOT connected as standard in the factory, so this task must be
carried out by the installer.
PLEASE NOTE: This thermostatic switch has no hard reset, so when the engine has cooled
sufficiently it will restart. Therefore, always disconnect the plug from the power supply during
maintenance!
Figure 17 Wiring diagram ZN045
Figure 18 Connecting the thermostatic switch
NB: an external protective device with a hard reset is available on request.
External protective devices are available for all types of fans. In combination with the internal
thermostatic switch, this protective device can turn off the installation via an alert and reset.
A 400 V 3-phase fan must always be fitted with external thermal protection! A thermostatic
switch which can be connected to external protection is also built in to the winding of the 3-
phase version.
