Assembly and Start-up
To mount the fan on a roof (of the industrial building) it is important to install it on a pedestal with
a suitable roof base.
It is recommended to apply the
TPD-N or TPDC-N sound absorbing
roof bases
(
delivery on
separate order
below, in Fig. No.4 and No.5 are given their dimensions
).
The application roof bases itself, reduces the noise coming into the process room by 12 up to 18
dB(A).
In
order to reduce more the noise level,
install a silencer beneath the roof base, suspending inside
the room.
Before lifting and installing the fan
(
onto the
roof base
)
it is important to use special lifting
eye bolts, screwed up to the disk
underneath the motor
– before doing this, take off the fan
hood. Do not use the motor eye-bolt handle for transporting the whole fan
!
