INSTALLATION AND COMMISSIONING
Installation
The fans should be mounted on plinths equipped with appropriate roof bases. To reduce the sound pressure
(noise), it is recommended to use TPD-N or TPDC-N type sound-absorbing roof bases of appropriate sizes and
TK type channel silencers. The use of a sound-absorbing roof base reduces the noise reaching the room by
approx. 12-18dB(A) .
SMART-SN fans should be transported on a pallet or using transport handles located under the cover on the
fan motor plate.
The fan must not be transported using the motor's transport eye! Use only the eyes mounted
on the fan motor plate.
