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.

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).
