2.9 Environment
The fan can generate positive pressure as
well as negative pressure. This means that
positive or negative pressure can be gene-
rated in the relevant areas. Make sure that
sufficient air is supplied in the right volumes
to the area in question.
2.10 Temperature and fire safety
Fan housings and other parts become hotter
when a heated medium is being transpor-
ted. During operation, the temperature of
the medium increases, which spreads to the
fan parts. The electric motor can also get
hot (especially in the event of overload). It is
important that the necessary measures are
taken to prevent fire and burns. In the event
of a fire, make sure that a fire extinguisher
designed for electrical equipment is used,
and follow the relevant recommendations for
fire and safety.
2.11 Unprepared start-up and electrical
disconnection
Before starting any work on the fan (e.g. in-
stallation, maintenance, servicing or dismant-
ling), the fan must be fully disconnected from
the mains. Under no circumstances may the
fan be reconnected while work is in progress.
NB: Single-phase fans with capacitors retain
energy for a limited time after the current is
disconnected.
The necessary safety measures must be ta-
ken to prevent unauthorised persons coming
into contact with live parts.
The fan is not equipped with any built-
in control system. This means that, when
connected to the mains, the fan will start
up immediately. Equally, the fan does not
have a system that turns it off permanently
in the event of a temporary power failure.
Make sure there is no risk of injury in such
an event.
Some motors have thermistors installed
and, if these have tripped (due to the motor
overheating), they will return to their origi-
nal position after cooling down. Make sure
nothing can cause a hazard in the event of a
temporary power failure.
If the impeller jams, it can suddenly start
moving on release. If the impeller jams, the
fan must be disconnected and repaired.
On electrical disconnection, the impeller will
continue to rotate for a limited time due to
accumulated energy.
2.12 Use
Improper installation and/or use may result
in damage to the fan and represent a hazard
to its surroundings. The fan may only be in-
stalled, maintained, dismantled and used by
qualified and authorised personnel (with due
attention to the relevant safety rules). Users
should know how the fan works and what
the consequences of improper use can be.
It is not permitted to operate a dismantled
or incompletely installed fan, e.g. where the
connection box has no lid attached.
When working on the fan (during e.g. instal-
lation and maintenance), make sure that no
unauthorised person enters the fan’s vicinity.
Modification of the fan is not permitted.
Complex maintenance work (such as removal
of the motor or impeller) must be carried out
by Fumex AB or with the latter’s permission,
in accordance with the latter’s instructions.
Improper assembly may result in poor fan
characteristics, damage to the unit and/or
risk of personal injury.
2.13 Dust
Avoid dust accumulation on and inside the
fan. Accumulated dust on the impeller may
cause imbalance. Dust on the grilles and
filters impairs the fan’s characteristics. Dust
on the fan housing and motor may lead to
impaired cooling, which may result in fire
(see
2.10 Temperature and fire safety
).
2.14 Potentially explosive environments
Contact with potentially explosive environ-
ments can lead to ignition. Use of the fan in
such environments is therefore not permit-
ted.
