1.2 Users
In principle, the Verti-Fan is not controlled directly, but by a user/operator via a control cabinet. These
users/operators must be at least 18 years old, employed by the company where the Verti-Fan is
installed, and designated by the management as competent and authorized to operate the Verti-Fan.
Unintentional users are any users who do not meet the above definition. Unintentional users are all
users who, by using the Verti-Fan, create unsafe situations or danger to themselves or others.
1.3 Use
The Verti-Fan is designed for vertical air circulation in greenhouses, to improve the homogeneity of
temperatures at different heights.
The Verti-Fan is not intended to be used for any other purposes than that described above, and is not
designed for the transport of gases other than air within a temperature range of -10 °C to + 50 °C.
1.4 Authorized servicers
The Verti-Fan may be serviced by any maintenance company, but Van der Ende Group is preferred
because of this company’s thorough knowledge of the Verti-Fan.
Periodic servicing can help avoid unnecessary costs or failures, and improve reliability.
1.5 Operating environment
The Verti-Fan should be installed on the lowest beam of the truss in the greenhouse. There must be at
least 300 mm clearance on the suction side of the fan. If a shade screen is used, this means that the
fan has to be installed lower than the lowest truss, and the mounting brackets adapted. It must not be
possible to touch the ventilator without special equipment, and the beam must be in good enough
condition to bear the weight of the fan.
The Verti-Fan is not intended to be used in any environment other than that described above. The
Verti-Fan is not suitable for use in explosive environments.
1.6 Guarantee conditions

2 DESCRIPTION
2.1 General
The purpose and function of the Verti-Fan is to displace air vertically from above to below in modern
greenhouses. Such displacements of air are often missing in modern, high greenhouses, with
consequent variations in temperature at different heights. Displacing air from above to below has a
favorable effect on growth, maturation and reduces the susceptibility to fungal diseases.
The operation of the Verti-Fan is simple: a horizontally placed fan draws air in at the top of the
greenhouse, and blows it down through a plastic hose. The plastic hose is kept open at the bottom by
a stainless steel ring or oval, and hangs 400 mm above the ground. The Verti-Fan therefore requires
mounting to the beam at the top of the greenhouse with the included bracket or suspension cable.
The Verti-Fan can be used in the cultivation of all sorts of vegetable, fruit and ornamental crops.
2.2 Transportation and Storage
The Verti-Fan is delivered in parts; in other words, the various components are supplied in separate
packages and assembled on site.

3 SAFETY INSTRUCTIONS
When working on the Verti-Fan, always make sure the plug is disconnected from the power supply!
This prevents the fan starting unexpectedly or unintentionally.
The Verti-Fan may never be connected to the power without the mounting ring and plastic hose. This
prevents a danger of cutting parts of the open fan blades.
When mounting the Verti-Fan, make sure that only self-locking nuts are used, otherwise there is a
danger that parts may vibrate loose and fall off.
Mind the fact that it takes a couple of seconds for the fan to start working when it has been turned on.
In compliance with EN ISO 13857, a protective construction has been fitted to the fan to prevent direct
contact. The protective construction consists of the plastic hose, the mounting ring and the hose
clamp. It is for this reason, that the Verti-Fan is not allowed to be operated without these components
being attached to the fan.

5 COMMISSIONING
This chapter describes the different electrical wirings that can be used to operate the FG035 fan. The
chosen connection determines the functionality of the Verti-Fan.
Annex B depicts a more comprehensive wiring scheme of the FG035 fan, including the connection
diagram for the 0-10 V control option.
5.1 Operating on basis of supply voltage
The FG035 is delivered with an extra cable. When this cable is connected (as shown by the red line in
Figure 8) in between the E1 socket and 10V socket, the fan will be turned off/on when it receives a
supply voltage. This cable needs to be connected before installation by the installer.
Connect the line voltage to: PE, L1, and N. Here, it must be strictly observed that the line voltage lies
within the allowable tolerance specifications (see technical data).
Figure 8 Wiring scheme FG035 fan
Proceed as follows:
•Remove terminal box cover;
•Insert and connect cables properly and ensure tightness of the cable glands;
•Connect the supplied cable between the E1 and 10 V sockets (see figure 8);
•Close the lid again carefully before start-up (tightening torque for lid screws 1.7 Nm);
Screw terminals
•Nominal torque: 0,8 Nm

oflexiblel: 0,75…4mm2
o18...12AWG

Page 17 of 28
5.2 Operating on 0-10V external setting signal
When the cable between 10V and E1 has not been connected, the fan needs to be controlled through
an external setting signal (0-10V).
Figure 9 depicts the characteristic curve of the fan’s motor torque to the specifications of the external
setting signal.
Figure 9 FG035 motor characteristic curve (0 - 10 V setting signal)
5.3 Prerequisites for commissioning
Before first-time start-up of the Verti-Fan, check the following:
•Has any leftover installation material and other foreign material been removed from the fan
area?
•Are the plastic hose, mounting ring and hose clamp correctly mounted to the fan, safety
devices according to (EN ISO 13857)?
•Check the rotat. direction (see the rotat. direction arrow on the fan blade, impeller base plate
or intake-side support plate).
•Check for quiet, low vibration operation. Strong vibrations due to erratic operation
(unbalanced), e.g. caused by transportation damage or improper use, can lead to failure.
For more information concerning the fan consult the FG035 user manual

Page 18 of 28
6 OPERATION
Operating the Verti-Fan is simple: if it is connected to the power supply it will start working, when it is
disconnected it will stop working. It is possible to set the speed by adjusting the voltage at the plug
with something like a control transformer, but this is not part of the Verti-Fan.
7 MAINTENANCE
When servicing the Verti-Fan, the plug must be removed from the socket, to prevent unexpected and
unwanted starting.
The advice is to do maintenance periodical (± half a year) to the Verti-Fan:
•Keep the top side (suction side) of the fan free of foreign objects and dirt.
•If the air intake grille is dirty, clean it with a dry brush and then wipe down with a damp cloth.
•If the fan blades or fan housing are dirty, wipe down with a damp cloth.
•Replace the capacitor after 10,000 operating hours. This will help maintain the correct speed
and avoid excessive power consumption.
•Check if the wire clamps are still tight in the case of cable mounting.
Other maintenance that must be taken into account at all times:
•Replace the plastic hose when damaged or soiled;
•If the device is not in use for longer periods in a humid atmosphere, it is recommended to
operate the motor/fan for at least two hours every month at 80 - 100 % of maximum speed to
remove any moisture that has penetrated inside.
•Check if all the bolt and nuts with which the fan is mounted are still tight. This prevents the
danger of unexpected falling objects.
