1. Introductory Remarks
The purpose of the present User’s Manual is to supply User with directions within the range of
application, installation, start-up and the operational use of the WPA-D-N roof radial fans.
Installing, start up and operational use are exclusively admissible after getting acquain-
ted with the contents of the Use and Maintenance Manual.
With regard to continuity of work carried on improvement of our products, we reserve for our-
selves the revision possibility of the draft and technological changes improving their functional
features and safety.
The construction of the WPA-D-N roof radial fans meets the requirements of the current state
of technology as well as the safety and health assurances included in:

2006/42/EC Machinery Directive of the European Parliament and of the Council of May 17th,
2006 on machinery –amending the 95/16/EC (recast) /Journal of Laws EC L157 of 09.06.2006, page 24/

2014/35/EC Directive of the European Parliament and of the Council of February 26th, 2014
on the harmonisation of the laws of the Member States relating to the making available on the
market of electrical equipment designed for use within certain voltage limits.
/Journal of Laws EC L96 of 29.03.2014/
The appliance meets the requirements included in:

2009/125/EC (ErP) Directive of the European Parliament and of the Council of October 21th,
2009 establishing a framework for the setting of ecodesign requirements for energy-related
products /Journal of Laws L285 of 31.10.2009/

327/2011 (EU) Commission Regulation of March 30th, 2011 on implementing the 2009/125
/EC Directive of the European Parliament and of the Council with regard to ecodesign requi-
rements for fans driven by motors with an electric input power between
125W and 500 kW /Journal of Laws L90 of 06.04.2011/
The device has been constructed and produced on the basis of following harmonized standards:

EN ISO-12100:2012
–
“Safety of machinery –Basic concepts, general princi-
ples for design. Risk assessment and risk reduction”.

EN 60204-1:2018-12

ling”

EN ISO 13857:2010
–
“Safety of machinery –Safe distances to prevent ha-
zard zones being reached by upper and lower limbs”.
2. Application
WPA-D-N roof fans have been designed for general ventilation and for local ventilation applica-
tions. They are installed outside the rooms (outdoor application)on roof bases or wall brackets.
As they feature increased fan pressure, they are efficient in application in installations with local
exhausts.
They fans are designed for conveying the air of dustiness not exceeding 0,3 g/m3, without viscous
impurities, aggressive contamination or compounds creating hazard of explosion.

3. Reservations of Producer
A.
Manufacturer accepts no liability for any consequences following from the operational use
that is in contradiction to the purpose of application.
B.
It is unacceptable to install on the device structure any additional elements not belonging to
its normal construction or accessory set.
C.
Any structural changes or modification of the device, carried out by User on one’s own are
not permitted.
D.
Protect the housing from mechanical damage.
E.
Prior to installing check the load capacity of the building structure where the device will be
mounted. Unsure mounting could cause risk to personnel / people in vicinity and effect in
damage of the device.
F.
The fan cannot be used for conveying the air contaminated with a mixture of flamma-
ble substances in form of gas, vapour, mist and dust that in connection with the air
create the explosive atmosphere.
G.
Do not use the fan for conveying the air containing viscous impurities that could accumulate
on the device surface, especially on the impeller.
H.
Neither use it for forwarding the air with aggressive pollutants which will destructively effect
the device structure.
I.
During operation, the maximum impeller rotations should not exceed the nominal rotations.
J.
Manufacturer is not responsible for wounds, injuries, body laceration experienced by User or
personnel during the improper operational use.

5. Structure and Function
The fan consists of a steel spiral housing, motor and an aluminium radial impeller (directly instal-
led at the motor pivot). The profiled impeller blades provide low acoustic performance of the fan.
The inlet is equipped with a flange to install the fan on a roof base or on a wall bracket. Typical
feature of the fan is a silencer fastened at the fan outlet of the spiral housing. It is possible to
install the silencer horizontally or vertically (see Fig. No.1, No.2). The version with the vertical
silencer must have introduced an additional elbow at the outlet and then the silencer (see Fig.
No.2).
For safety reasons, the inlet and outlet are equipped with protective grills. It recommended to
install TK silencers at the fan inlet (for details see acoustic data in the Table No.1).
On demand, we deliver isolating switches (safety switches) to cut off the power supply before
starting the installing and servicing activities.

ADDITIONAL EQUIPMENT –delivery on separate order:
●
motor protective switches WS –with short-circuit- and overload protection,
●
isolating switches (safety switches),
●
wall brackets,
●
silencers.
6. Assembly and Start-up
The appliance can work outside the industrial rooms (outdoor application). Manufacturer sug-
gests installing the fan on the roof base or on a wall bracket (delivery on separate order).
Before the connection to the power supply system, make sure if the parameters of the
existing electrical installation are corresponding the data on the nominal plate. In case
of inconsistency the connection cannot be executed.
Connection to the electrical power system has to be executed by User on one’s own by selec-
ecting the right type and section of the supply cable, and choosing the appropriate short-circuit-
and overload protection, according to the local conditions.
Connection to the power supply has to be carried out by an authorized
person with qualifications, according to the valid regulations and information placed in
Fig. No.4.
Before the start-up, check the connection between the motor and the PE protective cable, and
the correctness of the electrical connections. The impeller rotation sense ought to be accor-
ding to the arrow on the housing, in case of incompatibility change the phase connection
sequence.

7. Operational Use
Construction of the device guarantees a reliable function without continuous technical supervi-
sion after the start-up. If the place of operational use is changed –repeat the steps mentioned
in Section 6, according to the installing and adapting the ventilation system to the new applica-
tion and conditions.

9. Maintenance and Control
In the course of operational use, the fan construction guarantees its efficient function without
continuous routine technical supervision. Nevertheless, remember to carry out systematic mainte-
nance steps.
Once a year, submit the fan and the motor to technical revision –the electrical motor ought to
be examined according to the instructions of the motor manufacturer.
Every several years,examine the mechanical and electrical connections. The electrical instal-
lation system ought to be checked according to the standard PN-HD 60364-6 “Low-voltage elec-
trical installations –Part 6: Verification”.
Moreover, if any defective function of the unit or failure is noticed –undertake its additional con-
trol. Constantly, keep the inlet grills in clean conditions.
Any maintenance activities should be executed exclusively by an autho-
rised person with qualifications, and necessarily after disconnection from the power sys-
tem.
10. Occupational Health and Safety
Start up and the operational use are only admissible exclusively after getting acquain-
ted with the contents of the present Use and Maintenance Manual.The fan will not cause
hazard under the condition that it is firmly mounted to the supporting structure or to the venti-
lation system. Connect the fan to the electrical wiring system, strictly according to the enclo-
sed connection diagram and to the guidelines shown in Section 6 of the present Use and Main-
tenance Manual. This ought to be carried out exclusively by an authorized person with
qualifications, and in accordance with the valid regulations.
During the operational use, check the connection between the fan and the PE protective cable.
Any technical revisions and repair have to be executed, necessarily after
disconnection from the power supply system (isolating switch).
