Mounting
Remember
– all necessary safety equipment must be available before mounting.
It is very important to check that the surface the fan should be mounted on is leveled and even and
can carry the load from the fan.
When lifting the fan all equipment must be approved for the weight of the fan. Please find the
weight of the fan under the section weight.
The electrical connection must not be connected before the mechanical mounting is finished.
Mounting of the fan
The fan ground frame is normally bolted directly to a large concrete block. Make sure that the
ground frame is leveled. The height can be adjusted with small steel discs. When aligning the
machine, the installation accuracy must be maintained with max. 2 mm/m.
When the machines are permanently set up, the foundations must be correctly made in accordance
with DIN 4024, Part 2.
Before connecting the fan inlet and discharge, make sure that no unwanted objects are located in the
inlet or discharge channels and the fan itself. The fan is constructed to deliver a discharge pressure
above barometric pressure so make sure that the inlet channel can not be blocked.
Make sure that the fan and motor shaft can be rotated without obstruction. This is checked by rotate
the shaft by hand.
The bearings must not be relieved.
Make sure that the bearing houses are filled up (to normal level) with oil/grease.
Make sure that the motor is correctly connected to the power supply.
Make sure that the belt drive/coupling is aligned up correctly.
Make sure that the belt tension is right according to the instruction.
Make sure that all bolts for fixing bearings, motor, consoles etc. are tightened.
Make sure that the inspection hatches are closed and tightened.
Make sure that the drains are closed and tighten.
