chem-proof Ex roof fan
SPARK-CHEM/Ex
Technical revisions on the fan must be performed exclusively by an authori-
sed person with qualifications.
Additionally,
the
fan should
necessarily be
disconnected from the power supply system
.
During the technical
revisions,
follow the instructions
included in
the
User’s Manual of
the motor, that constitute integral part
of the main Use and Maintenance Manual of the
fan
.
Within the scope of the technical revision:
–
keep clean the inlet grill;
–
periodically, check the mechanical- and electrical connections.
Moreover, in case of faulty
function of the unit
– undertake its technical revision;
–
carry out the inspection
of
the
fan (
the
motor
– according to the instructions of its manufac-
turer). Within the scope of the revision, clean the fan of the deposited impurities/pollutants.
Before
the
activities undertaken on
the
fan, follow the subsequent steps:
– disconnect the fan from the power supply. Exemption from this are ac-
tivities carried out on the running fan,
e.g. measuring of the vibrations. In this case es-
pecially it is important to follow the regulations of the Occupational Health and Safety.
– Wait until the 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 ha-
zard under the condition
it
is correctly
and
firmly installed
within the
ventilation system
or to the
supporting structure.
Any installation activities related to
the
power supply system, have to be carried out strictly ac-
cording to the enclosed
Connection Diagram
and in accordance
with the instructions given in
Section 6 of the present Use and Maintenance Manual.
Connection to the
power supply system ought
to be
carried out
by an au
-
thorised person with
qualifications, according to the being in force regulations.
The fan
motor must be protected from the short-circuit and overload effects.
In the course of operational use, examine
the
fan 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 with
“loose garment/clothing” or putting the hand towards the
open inlet
of the
running fan can cause hazard
of
accident
and
severe
disabi
-
lity.
11. Transport and Storage
The fans are wrapped in foil and placed in cardboard packages. Larger fans can be transpor-
ted on pallets, protected from displacement / slide and overturn. To lift the fan use the special
transport handles (located on the motor housing). During the transport,
protect
the
fan from
damage of its components,
whereby
that would result in reduction
of the circumferential gap
between the impeller and the inlet confusor (funnel).
