1.2.9 temperature (hot surfaces)
The housing and fan elements take the temperature of transported medium. During work (e.g. as a result of compression
process) the temperature of medium, housing and fan components increase. Electric motor may heat up to high temperatures
(especially when overloaded/overheated). The appropriate steps need to be made to prevent from fire and burns caused of
high temperatures.
In case of fire – to extinguish a fire use fire extinguisher approved for electrical equipment and follow
recommendation of fire department
.
1.2.10 unexpected start / connecting power supply
● Before undertaking any kind of work on fan (e.g. installation, maintenance and inspection, disassembly), it has to be completely
and reliably disconnected (isolated) from power supply (check there is no voltage). It has to be ensured, that power supply will
not be connected during work on fan and moveable parts are not moving.
The appropriate steps need to be made in order to provide protection against electric shock and to prevent from access to electrical
components by unauthorized person.
● Fan is not equipped with control system – the connecting of power supply causes immediate start-up. The device is not
equipped with system, that would permanently shut it down in case of temporary power supply loss. It has to be ensured, that
any dangerous or unpermitted event does not occur in case of temporary loss of power supply.
● Thermal sensors installed in motor (if fitted) after tripping caused by motor overheat turn back to initial state after cooling down. It has to be
ensured, that any dangerous or unpermitted event does not occur in case of action of thermal sensors and after motor cooling down.
● In case of impeller jamming – its unblocking may cause sudden movement. Appropriate steps should be made in order to avoid impeller
jamming. In case of impeller jamming, fan should be completely disconnected from power supply and inspected (section 5).
● After disconnecting from power supply fan still works for certain time (moveable parts are moving) as a result of energy accumulation.
1.2.11 use
Improper installation and/or use may lead to damage of the device and occurrence of dangerous situation. The unit can by installed,
maintained, dismantled and used only by qualified and authorized personnel, in accordance to safety rules and current regulations in the
country of use (including proper electrical authorization). Personnel need to be familiar with reactions caused by the fan.
Using of fan in dismantled/uncompleted state is forbidden, e.g. with dismantled review cover.
During the works (e.g. maintenance, installation) the fans surrounding should be protected from bystanders approach.
Any modifications of the unit are forbidden. Complicated maintenance work (such as dismantling the motor or impeller) need to be made by
Venture Industries Sp. z o.o. service or with it permission - according to additional guidance. Improper assembly may lead to reduce the fan
parameters, damage the unit and lead to the dangerous situation.
1.2.12 Accumulation of dust
Prevent the accumulation of dust, sediment on and inside the fan. Dirt accumulated on: grids – may reduce the fan parameters; impeller –
may lose it balance; housing and motor – can reduce the cooling; hot surfaces (see 1.2.9) – may ignite.
1.2.13 explosive atmospheres
Contact of the fan with explosive atmospheres cause in ignition. It is forbidden to contact the fan with explosive atmospheres.
