2. Application
In general, WPA-E-N fans have been developed for local ventilation. They have to be installed
on wall brackets inside buildings (indoor application). As they can overcome significant flow re-
sistances, they are especially appropriate for application in systems with local exhausts.
Radial stand fans are designed for conveying the air of dustiness not exceeding 0,3 g/m³, without
viscous impurities, without aggressive pollutants or substances creating explosion hazard.

5. Structure and Function
The fan consists of a spiral steel housing and a motor with directly mounted (on its shaft) radial
aluminium impeller. Its impeller with profiled blades provides low acoustic pressure level. The
fan Inlet is equipped with a mounting flange to install the fan on a wall bracket or on a filtering
unit. Whereas, the fan outlet is ended with a round connection fitting piece, for a safe attach-
ment of the rigid seam spiral ducts or for flexible connections. For safety reasons, both, the fan
inlet and outlet are equipped with protective grills. It is recommended to install silencers type
TK on the inlet and outlet (see acoustic data in Table No.1).

6. Assembly and Start-up
The appliance has been developed for use in industrial rooms. Manufacturer suggests instal-
ling the fan on a wall bracket (delivery on separate order).
Prior to connection, make sure whether the parameters of the hitherto existing electri-
cal installation are matching the values on the nominal plate. In case of inconsistence
the connection cannot be executed.
Any activities related to connection to the power supply line has to be carried out by User on
one’s own. Additionally, important is to select the appropriate sort and section of the power
supply cable, according to the regulations, and selecting the short-circuit- and overload pro-
tection, with reference to the local conditions.
Any activities related to connection to the power supply system ought
to be executed by an authorized person with electrical qualifications and according to
the being in force regulations and to the information in Fig. No.3.
Fig. No.3 –Connection Diagram –WPA-E-N
Before the start-up check the connection between the motor and the PE protection cable and
the correctness of the electrical connections (impeller rotation sense has to be according
to the arrow on the housing –if opposite –change the phase connection sequence).

7. Operational Use
Construction of the device provides reliable function, directly after its start-up without conti-
nuous technical supervision. If the place of operational use is changed –repeat the steps as
mentioned in Section 6, according to the installing and adapting the ventilation system to the
to the new conditions.
In case when any failure or defective function of the device is visually or by noise noticed, take
steps as stated in the Section 8.

9. Maintenance and Control
During the operational use,the fan construction guarantees its efficient function without conti-
nuous everyday technical supervision. Nevertheless, in the course of operational use, remem-
ber to undertake systematic maintenance steps.
Once a year the fan should undergo technical revision –the electrical motor ought to be exa-
mined according to the instructions of the motor manufacturer.
Every several years, check the mechanical and electrical connections. The electrical installa-
tion must be examined according to the PN-HD 60364-6 “Electrical installations of low voltage
–Part 6: Verification”.
If faulty function of the system is noticed, undertake additional control. The inlet grills must be
kept in clean state.
Any maintenance activities ought to be executed exclusively by an autho-
rized person with adequate qualifications, and after disconnection from the power sup-
ply system.
10. Occupational Health and Safety
Start up and the operational use is only admissible exclusively after getting acquainted
with the contents of the present manual. The fan will not cause any hazard to User/person-
nel, if it is stably installed to the supporting structure or fastened within the ventilation system.
Connect the fan to the power supply system, strictly according to the enclosed Connection Dia-
gram and the guidelines shown in Section 6 of the present Use and Maintenance Manual.

10
stand radial fans WPA-E-N 04.06.2019
Any activities connected with energizing ought to be executed exclusive-
ly by an authorized person with adequate qualifications and in accordance with the valid
safety regulations.
The motor ought to be protected from the short-circuit- and overload effects. During the opera-
tional use, check the connection between the fan and the PE protective cable.
Any technical revisions and activities connected with repair, have to be
executed, necessarily after disconnection from the power supply system (isolating switch).
