Directly to the wall

Seismic Restraints for Mechanical Equipment Directly to the wall

Equipment should have pre-installed brackets that can support attachment to the building as shown in Figure 124.

***Figure 124:*** *Direct attachment to a wall.*

Step 1: Determine where to bolt the equipment

Accurately draw the bolt pattern on the wall using one of the following methods:

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

Masonry walls may require additional holes in equipment attachment brackets as shown on construction drawings or in the equipment manufacturer’s instructions.

ONLY USE MOUNTING BRACKETS PROVIDED. DO NOT DRILL INTO THE EQUIPMENT HOUSING.

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

Step 2: Install post-installed anchors

If anchoring to concrete, install post-installed anchors.

Step 3: Move the equipment into place

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

Step 4: Attach nuts

Attach nuts to the anchor or bolt and torque according to the manufacturer’s instructions.

Piping, ductwork, and raceways may be connected.
