correct air flow.
- Possible harmful effects due to noise are to be carefully studied.
Therefore, before positioning, study and treat the various possible noise transmissions ;
The assistance of an accoustic
specialist may be usefull.
- The unit must be levelled on resilient mounts.
- If required, fit the pipework with rubber expansion joints (optional)
