PLACING AND SECURING LIST 16 DISTRIBUTION ONLY BAYS

• Figure 2-3 provides List 16 Distribution Only Bay hole drilling patterns.

• Bays are typically placed next to each other and bolted together. Refer to the

previous Section, GENERAL REQUIREMENTS, for bay line-up recommendations.

Procedure

1) If bays are to be placed next to each other, remove the side cover panels from

the sides that will be placed next to another bay (leaving the side cover panels on

the "outside side" of the two end bays). Install side cover panels on end bays as

required.

2) Place bay(s) in position. Note that clearance holes for 1/4” bolts are provided in

the side rails of each bay. These holes are for bolting the bays together.

3) Remove the lower rear cover panel from each bay to provide access to bay's

floor mounting holes. These cover panels will be re-installed after all mounting

and electrical connection procedures have been completed.

4) Level bay(s) as required, using the leveling nut provided in base plate. Adjust

leveling bolts so that all bays are even at top, and bolt holes in the side of each

bay line up with holes in the adjacent bay(s).

5) Bolt all bays together. Use 1/4” hardware, seven places per pair of bays. Use a

ground washer in two locations with the 1/4" hardware bolting two bays together.

Note: A ground washer is an internal-external tooth, dish-type lock washer.

When installing ground washers, ensure that the ground washer is

oriented so that the teeth dig into the paint on the metal part the ground

washer is secured to (concave side faces the metal part).

6) Install shims between bottom of each bay and the floor as required to distribute

floor loading.

7) Secure bay(s) to floor using fastening hardware per site requirements.

8) If the outside sides of the end bays do not have side cover panels, install them

now (two per side). Note that ground washers are used with each screw

securing the side cover panels.
