The device must be mounted in the horizontal orientation with cover on top, in accordance with drawing below (the arrows show the air flow
direction). The fan needs to be mounted to external constructions (we recommend use of dedicated roof stand) with use all montage holes
placed on the fan base. Due to the use of the fan outdoor – prevent form leakage of water between the fan base and montage construction by
proper sealing.
The fan support construction must be able to support the fan working with the full power (start-up, breakdown, improper use should by also
consider). For installation use connecting elements secured against self-loosening.
Note:
Fan housing is made of aluzinc steal / zinc steal (depending of fan model).
Install proper protective structures, grids (inlet, outlet, moving parts), if not mounted by manufacturer. Open inlet of the fan need to be
protected proper by proper grid.
Note:
Although normally used shields the device should be installed in such a way that prevent from getting access to the device (rotor) from
the outlet.
It is recommended to use accessories to minimize the vibration transmitted from/to the fan.
It is recommend to provide the distance of 3 inlet dimensions of clearance between inlet and any obstructions (such as filters, bends, wall)
and distance guaranteeing free air movement.
After fan mechanical installation make all electrical connections and check the impeller direction of rotation in accordance with points 3.2
and 3.3.
Ensure that there are no foreign bodies (eg. mounting elements, tools) inside and near of the unit, that impeller is not blocked, the fan is
properly secured after installation (the cover is closed and secured, the terminal box/service switch is closed, the fastening elements are
properly tightened).
3.2 electrical connection guidelines
The fan and power supply network must be secured in accordance with local law requirements.
Use protection against short circuits, overloads and for fans with three phase power supply - voltage failure/unbalance.
Use appropriate protection against electric shock - it is required to connect fan grounding terminal placed inside connection box to proper
grounding system.
The electrical connection need to be made in accordance with the data on the fan and motor nameplates, motor manual (if included), proper
wiring diagram and fan marking.
Depending on the chosen speed regulation method it is needed to connect adequate devices or signal wires to speed regulation system
terminals (see appendix C).
Voltage and frequency of supply network should be as indicated on the fan nameplate. The fan has built-in speed regulator.
It is forbidden to use voltage or frequency regulators to supply unit. Voltage or frequency regulation is ineffective and could
lead to the fan damage.
Use electrical wires with proper insulation and size. Wires should be placed in way that in any situation will not touch the moving elements,
and that the water (e.g. from condensation) not flow inside the junction box. Wires should be connected to the terminal box, through properly
tightened cable glands and wire fasteners.
3.3 rotor rotation direction
The fan has built-in speed regulator which do not allow to change the direction of rotor rotation, although if the impeller would rotate in
incorrect direction contact with manufacturer.
4. USE
During fan use follow the guidelines contained in 1 section of this instruction and
use guidelines
.
Before first start of the fan follow guidelines from chapter 5.
4.1 use guidelines
Make sure that turning on of the fan does not make any risk for personnel and property.
Fan cannot work with voltage, frequency, current higher than shown on the fan nameplate.
The fan is designed for continuous operations (S1) – too high frequency of turning may lead to the motor regulator overheat and damage
(see also chapter 4.2 Guidelines for regulation).
In case of activation of any electrical protection, detection of damage, working with current greater than specified on the fan nameplate –
unit must by immediately turn out off use.
During fan regulation – follow regulation guidelines in chapter 4.2.
