Notes:
1.
For suspended floors lighter than 102 mm (4") concrete, select
deflection requirement from next higher span.
2.
If equipment is located in a building separated from building housing
patients, isolator pads are not required.
3.
Provide pads (D) for domestic water booster pump package.
4.
This chart applies to non-seismic areas. If in VA Seismic Area A or B,
substitute DS for D, and SS for S.
5.
SI Conversion: 25 mm = 1", 43 mm = 1.7", 1200 W = 1-1/2 HP, and 7500 W
= 10 HP.
