Maintenance
The construction and a solid execution of the fans guarantee their operational use, without con-
stant routine maintenance, provided that the operational use is correct.
To
obtain
correct functional performances and to meet
the safety rules, it is recommended to sub-
mit the fan to technical revision in regular periods of time (i.e. once a year).
During the revision take into account the function of the fan as well as its technical state.
All the activities connected with
technical revisions on the fan have to be
carried out
exclusively by an authorised person with adequate
qualifications
and
necessa-
rily after disconnection from the power supply system
.
Additionally, observe the rules
of Occupational
Health and Safety.
(
Non-compliance
of the
rules could result in threat to life and health of the employees
).
To disconnect the fan from the
master circuit
of the power
supply,
use the
isolating
switch
(
IS
)
, which should be ordered
and
installed by User
. Isolating switch ought to be installed
within reach of the servicer.
Isolating
switches (IS) are offered by KLIMAWENT S.A.
as additional accessory. The way of con-
nection is shown in the operation manual of the insolating switch (IS).
There are subsequent activities within the range of technical revision:
● examine and tighten up the mechanical- and electrical connections,
● check the mounting of the motor and fan, whereby mind if the clearance between the impel-
ler and the non-rotary elements is equalised in the whole circumference,
● remove the impurities (eventually) deposited inside the fan.
Prior to the re-start of the fan
carry out the revision steps as listed in the Section 6
“Assembly
and Start-
up” of the present Use and Maintenance Manual.
Exemption from this are tests that
need
to be carried out on the
device being in run, along
with the strictly followed rules of Occupational Health and Safety
–
as an example
– mea
-
suring of vibrations.
During the revision activities
it is important to follow the safety regulations.

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 will not cause any
mechanical hazard when it is correctly and firmly mounted
to the roof
base
or another constructional element
of the building that has adequate load carrying capacity.
