Assembly

1.Position platform base as shown below in Figure A with the grate side up.

2.Attach the left and right handrails to the platform base with (3/8 in. x 3/4 in.) hex head bolts and (3/8 in.) hex nuts as shown in Figure A. Use six bolts and nuts on each rail.

3.Raise the platform base, grate side up, with a crane or forklift.

4.Attach legs to the slots on sides of platform base with two (3/8 in. x 3/4 in.) hex head bolts and (3/8 in.) hex nuts.

6.Facing the control panel side of the unit, find the center of the housing and drill a (7/16 in.) hole through the housing and support stand (3/8 in.) above the form line as shown in Figure C.

Next, drill two more (7/16 in.) holes through the housing and support stand (12 in.) on either side of the center hole, (3/8 in.) above the form line. These holes are used to attach the platform base to the unit.

7.Attach the service platform to the control panel side of the housing by inserting the three (3/8 in. x

1-1/2 in.) bolts of platform base into the three holes of the housing. Securely fasten with three (3/8 in.) hex nuts.

8.Level service platform if necessary by adjusting legs and then attach leg cross member with two (3/8 in. x 3/4 in.) hex head bolts and 3/8 in. hex head nuts.

9.Securely fasten all nuts and bolts. Make sure all nuts and bolts are tight.

10.Attach arm rails of service platform to the housing by first drilling a 5/16 in. hole through the housing at the attachment point as shown in Figure D. Secure arm rails to the housing with (3/8 in. x 1 in.) thread cutting screws. Be sure not to over-tighten screws.

11.Attach safety chains to the right hand rail, across the entryway. Assembly is complete.

Figure A

5.Fasten three (3/8 in. x 1-1/2 in.) hex head bolts into the side of the platform

base. Secure each bolt with two (3/8 in.) hex

head nuts placed back to back on each bolt as shown in Figure B. These bolts will be used to attach the platform base to the unit.
