I. Installing expansion tubes and nuts

Prior to installation, clean dust inside and outside the holes with a dust collector and then measure the spacing of holes. If errors are not acceptable, you must measure and drill again.

Follow these steps to install an expansion bolt:

1)Take down the expansion tube and expansion nut, and insert the alignment rib on the expansion nut into the alignment groove of expansion tube.

2)Put them into a hole vertically.

3)Punch the expansion tube with rubber hammer until the expansion tube is completely buried into the floor.

Figure 8-25illustrates how to install an expansion nut to an expansion tube.

Caution:

You must insert the alignment rib of expansion nuts into the alignment grooves of expansion tubes, or you will be unable to install or fasten the expansion bolts.

II. Adjusting rack height

According to the floor height and the height silkscreen of the antistatic floor on the rack, adjust all racks to the estimated height and torque the retaining bolts to 45 Nm with a torque spanner, from middle to the two sides, as shown in Figure 8-26.
