5. TRANSPORT AND HANDLING
Transport and handling must be performed with great caution to prevent the device from damaging.
Fans should be transported on covered means of transportation, in wooden boxes, on metal pallets or
carton packages protecting against water and moisture.
The packaging should maintain fans in new, factory condition during storage and transportation, and ensure
the correct operation of the fan, when it is delivered to the installation location.
When packing, special attention should be paid to stability and inertia of the fan in its packaging.
Fans and their parts should not be stored in a room with chemical substances causing metal corrosion.
Fans should be stored in dry and permeable to air containers, free from gases, fluids and caustic vapours,
which are harmful to motor isolation and other fan parts.
Fans cannot be stored in rooms, where chemical fertilizers, chlorinated limes, acids, chemical substances,
etc. are stored.
The ambient temperature in the room, where fans are stored, cannot be lower than 278K (+5°C), and
relative humidity cannot exceed 70%.
6. INSPECTIONS AND MAINTENANCE
Each working fan should be subjected to periodical inspections:
small inspection – every 12 months,
main inspection:
o
motors of the rotational speed of n = 1500 rpm -
- after 6000 working hours
o
motors of the rotational speed of n = 1000 rpm -
- after 7000 working hours, but no seldom than every 3 years.
