5. Structure and Function
WP-11/Ex consists of two bell-shape plastic (HIPS conducting) draw pieces. Both elements
are crewed together with larger perimeters, forming the area for the motor with a rotary stator.
The radial impeller is fastened to the stator. Free ends (of the two housing parts are suitable
to the standard diameters of rigid round ventilation ducts.
Outside the housing is located a terminal box (Ex execution) for connection to the 3x400V po-
wer supply. Additionally, the housing is equipped with a mounting plate, to install the fan at
the supporting structure –by means of four M6 bolts.
Flow direction is indicated with an arrow on the fan housing. The fans have to be installed be-
tween the round ventilation ducts of appropriate diameter. The appliances feature small dimen-
sions and very silent work.
Isolating switches are additional equipment and are delivered upon separate order.
6. Assembly and Start-up
Before the installing, and after the fan is taken out of the transport package, check the state
of the fan (if there are no damages that occurred during the transport). WP-11/Ex duct fans
are installed inside the rooms (indoor application), in vertical and horizontal round rigid ven-
tilation ducts of round section (see Table of dimensions).
The air flow is indicated by an arrow on the fan housing. The arrow shows how should the
fan be installed in the ventilation ducting (as a positioning). The fan housing should be fas-
tened to the ventilation ducts with rivets or plate screws.
Additionally, the connection “fan-duct” ought to be sealed with “silicone” or a sealing adhe-
sive tape. Apart from the “fan-duct” fastenings, it is important to attach the fan to the suppor-
ting construction (4 bolts M6). This ought to be performed by User on one’s own, with refe-
rence to local conditions.
Prior to the connection to the power supply system, make sure if the parameters of the exis-
ting system is in accordance with the parameters on the nominal data plate. In case of diffe-
rence it is not possible to carry out the connection.
The appliance ought to be connected to the supply by operator on one’s own – whereby it
is important to select the sort and section of the supply cables and the protection from the
short-circuit- and overload effect, according to the local conditions.

Connection to the power supply ought to be executed by an authorised
person with confirmed qualifications, according to the valid regulations of Occupational
and Health Safety and with the instructions given in Fig. No4.
CAUTION: The fan is equipped with protective cables, that should be connected to the ventila-
tion ducts. Additionally, the ventilation ducts ought to be grounded too. In this way the whole
ventilation system is protected against the accumulation of electric loads.

The overload protection of the motor should feature such time-current characteristics that ensu-
res the motor disconnection from the supply in a time that is shorter than the tE time (as speci-
fied for the given motor), while the current equals the start-up current of the motor.
7. Operational Use
In general, the construction and the reliable execution of the fan, guarantees its operational use
without constant routine maintenance. Nevertheless, check periodically the mechanical and ele-
ctrical connections, the state of grounding and efficient cooling for the motor.
Following use of the fan is treated as incorrect:
a)
conveying the aggressive media,
b)
forwarding the media of high dustiness or contaminant particles content,
c)
use of the fan in area where the ambient temperature of the motor exceeds +40ºC.
Consequences of incorrect use:
a)
breakage of bearings,
b)
damage caused by corrosion,
c)
balance loss of the rotary elements,
d)
vibrations,
e)
deformations,
f)
damages caused by friction.
Hazards caused due to incorrect use –damages or other effects caused by:
●
burst of the impeller,
●
crack / burst due to wear of material,
●
fire and explosion induced by sparks,
●
vibrations,
In case when any defective device function is detected (e.g. increased noise level, vib-
rations, reduced flow efficiency), it is important to disconnect the fan from the power
supply, and to undertake its technical revision in order to reveal the reason of the func-
tional disturbance.

9. Maintenance
Construction of the fan guarantees its longevity and reliable function without the constant
routine technical supervision.
To obtain correct functional performances and to meet the safety rules, it is recommended
submit the fan to technical revision in regular periods of time.
Technical revisions on the fan must be executed by a qualified person with
adequate authorization. Additionally, the fan necessarily should by discon-
nected from the power supply system.
During the technical revisions, follow the recommendations and instructions included
in the User’s Manual of the motor, that constitute integral part of the main User’s Ma-
nual of the fan.
Before any revision activities on the fan, follow subsequent steps:
–disconnect the fan from the power supply system. Exclusion from it
are activities that must be carried out on the running fan, i.e. vibration
measurements. Whereby, observe strictly the Occupational and Health
Safety regulations
–wait until the impeller stops its rotations
Within the scope of technical revision carry out following steps:
–
examine and tighten up the mechanical- and electrical connections; moreover check if any
malfunctions are by noise or visually perceptible –if this is the case, undertake its control.
–
undertake the inspection of the fan (radial impeller of the fan motor –according to the in-
structions of the manufacturer). During the technical inspection, clean the fan from deposi-
ted impurities.
Restart of the fan is possible, after the control steps as described in Section 6 “Assembly and
Start-up”.
