Horizontal installation

1 Make the required ceiling opening for installation in an
applicable place.
It may be necessary to reinforce the suspended ceiling frame
to keep the ceiling level and to prevent it from vibrating.
Consult the builder for details.
2 Install the suspension bolts. Use either W3/8 or M10 size bolts.
Use anchors for existing ceilings, and a sunken insert, sunken
anchors or other field supplied parts for new ceilings to
reinforce the ceiling in order to bear the weight of the unit. Refer
to it to check for points requiring reinforcing. Adjust the
clearance from the ceiling before proceeding further.
