NOTES
1
Install a canvas duct to the air discharge outlet and air inlet so that vibration from the machine body is not transmitted to the duct or ceiling. You should also apply acoustic (insulation material) to the inside of the duct, and
vibration insulation rubber to the suspension bolts.
2
Install suspension bolts.
Use bolts of 10 mm diameter.
Install the equipment where supporting structures are strong enough to bear the equipment’s weight. Use embedded inserts or anchor bolts with new buildings and hole-in-anchors with old buildings.
NOTE
1
All the above parts are to be procured in the field.
