●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.
•
Capacitor (only single phase fans) is still energized for certain period of time after turning off the power supply.
•
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 need to be made in order to avoid impeller
jamming. In case of impeller jamming, fan need to be completely disconnected from power supply and repaired.
●AHer 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. without junction box cover.
•
During the works (e.g. maintenance, installation) the fans surrounding needt to 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 – 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.
2. TRANSPORT AND STORAGE
During transport and storage follow the guidelines contained in 1 chapter and
transport and storage guidelines
.
2.1 transport and storage guidelines
•
The fan should be transported and stored in original packaging, without excessive shocks. The device must be protected from weather
conditions, transported and stored in dry, well ventilated, and free from substances harmful to the device areas. The fan cannot be
transported and stored in areas with fertilizers, chlorinated lime, acids and other aggressive chemicals. Fan should be protected against foreign
body entrance.
•
During transport and storage protect the fan against damage (including crush).
•
The unit should be lifted by elements designed for it (according to Fig. 1). Do not lift the unit by motor elements, wires, etc.
During lifting the
unit must remain stable.
Fig. 1
•
Do not come beneath lifted unit. When cables break, falling unit could cause serious injury or death.
•
It is recommended that storage time not exceed one year. After long storage, check the fan. (chapter 5). It is recommended to once a month
manually rotate the impeller (at least 3 rounds).
