5. Structure and Function
The fan consists of a steel spiral housing, motor with installed on its shaft aluminium radial im-
peller. The impeller blades remind the airplane wing cross-section and provide low acoustic
pressure level of the fan.
The fan inlet is equipped with a flange to install the fan on the wall bracket or on a filtering unit,
whereas, the fan outlet is ended with a round fitting piece, for a safe connection of the spiral
seam duct (rigid conduit) or flexible connectors.
For safety reasons, the inlet and outlet are equipped with protective grills. It is recommended
to install silencers type TK at the inlet and outlet of the fan (see acoustic data in Table No.1).
ADDITIONAL EQUIPMENT –delivery on separate order:
■
motor protective switches WS –with short-circuit- and overload protection
■
wall brackets
■
silencers
It is important to fasten a protective cable (at the fan housing)to conduct the electrostatic char-
ges away. Additionally, on the motor housing is located a clamp to attach the protective cable,
which should be connected to the grounding. On the motor housing is placed a terminal box of
electrical supply.
6. Assembly and Start-up
The fans are meant for application within the industrial rooms. It is recommended to mount them
them on wall brackets (as additional equipment according to separate documentation). The fan
outlet must be connected with the discharge duct through a flexible section (made of antistatic
material). The connections should be fastened according to the configuration of the ventilation
system and its technology, and they ought to be suitable, with reference to the condition clari-
fications at the installing place. It is recommended to use silencers at the inlet and outlet.
User, who is performing the assembly is responsible for the compatibility with the reso-
lutions of EN ISO 13857.

9. Maintenance
Chiefly, the construction and solid execution of the fan guarantees its operational use, without
constant routine maintenance. To obtain correct functional performances of the fan and to meet
the Occupational Health and Safety, it is recommended to carry out technical revisions of
the fan in regular periods.
Technical revisions on the fan must be executed by a qualified person with
adequate authorization. Additionally, the fan should be necessarily discon-
nected from the power supply system.
In the course of technical revisions, follow the recommendations included in the User’s
Manual of the motor, that constitute integral part of the main Use and Maintenance Ma-
nual of the fan.
Scope of the technical revision:
–
Systematically, keep clean the inlet grill.
–
Periodically, check the mechanical and electrical connections. Moreover, when defective
function is by noise or visually spotted –undertake technical revision of the assembly.
–
Execute the check of the fan (motor –according to instructions of motor producer). During
the revision, clean the fan of the accumulated impurities.

11
04.06.2019 explosion-proof stand fan WPA-E-N/Ex
Before the start-up, follow subsequent steps on the fan:
–
Disconnect the fan from the power supply. Exemption from this are ac-
tivities that must be executed at the running fan, i.e. vibration measu-
ring (especially here are important Occupational Health and Safety re-
gulations).
–
Wait until the fan impeller stops rotating.
The fan can be restarted after the control steps are carried out, strictly as described in Section
6 “Assembly and Start-up”.
10. Occupational Health and Safety
Start up and the operational use of the fan are admissible after getting acquainted with
the contents of the present Use and Maintenance Manual. The fan shall not cause any me-
chanical hazard when it is correctly and firmly mounted to the floor or another constructional
element of the building.
Any installation activities related to the power supply, have to be carried out strictly according
to the enclosed Connection Diagram and in accordance with the instructions given in Section
6 of the present User’s Manual.
Connection to the power supply system ought to be carried out by an au-
theorized person with electrical qualifications, according to the valid regulations. The fan
should be protected from short-circuit and overload effects. In the course of operational
use, examine the connection to the PE protective cable.
Any revision activity and repair must be executed after the fan is disconnec-
ted from the power supply system. Approaching in “loose garment/clothing”
or putting the hand into the open inlet of the running fan can cause risk of
accident and severe disability.
