Directly to the floor/pad

Equipment may be bolted or welded to the building floor or pad. To bolt to concrete, use post-installed anchors, embedded headed studs or embedded j-bolts.

Attachment of equipment with sheet steel housings is shown in Figure 68.

Attachment of equipment with a steel structural framing or base is shown in Figure 69.

Do not add shims under equipment with sheet steel housings as shown in Figure 67 above. If concrete floor/pad is irregular, reinforce housing with angles as shown in Figure 71.

Step 1: Determine where to bolt the equipment

Accurately draw the bolt pattern on the floor, concrete pad, or steel beams using one of the following methods:

• Set the equipment in place and mark the holes.
• Make a template.
• Use measurements and shop drawings to lay out the bolt hole pattern.

You may drill additional holes into the equipment assembly or building steel beams as shown on construction drawings or the manufacturer’s instructions.

USE CAUTION WHEN DRILLING INTO EQUIPMENT. Internal components can be damaged or the manufacturer’s warranty may be voided. DO NOT DRILL OVERSIZED HOLES.

New holes cannot be oversized or oval in shape. Repair oversized holes as shown in Figure 70, if necessary.

Step 2: Install anchors

If the equipment is to be anchored to concrete, drill and install post-installed anchors or pour concrete with castin-place studs or J-bolts.

If the equipment is to be bolted to steel, drill holes in the steel as shown on construction drawings or the manufacturer’s instructions.

Step 3: Move equipment into place

BE CAREFUL NOT TO DAMAGE THE ANCHORS WHEN SETTING THE EQUIPMENT.

Step 4: Attach nuts or weld equipment

Attach nuts to the anchor/bolt and torque.

Weld equipment to steel beams or embedded plates.

Piping, ductwork, and raceways may be connected.
