13. Lift the UERV at least 3' (feet), remove the nut and bolt
assembly and slide the telescoping leg out of the
guide. Position the stand off legs so that the foot is on
the bottom of the stand and reinstall the nut and bolt
assembly. Do not tighten nuts at this time as the legs
will have to be adjusted once the unit is finally set in
place
14. Locate provided roll of ¾" x 1 ¼" gasket material. Apply
gasket down the center post of the UERV as well as
between the platform support rail and adaptor panel.
15. Remove screw from the top panel of the RTU in order
to enable lifting the top panel of the RTU up at least 2".
Note: An equipment support or pressure treated
2x6x60" piece of wood should be placed under the
end of the UERV to prevent roof penetration by the
standoff legs.
16. Lift the UERV then move it into position in front of the
horizontal return air adaptor panels.
17. Lower the UERV into place against the RTU, catch the
bottom of the UERV on the platform support rail. With it
in place remove the bolt assembly placed in the
standoff legs in Step 13 and adjust the legs on the
UERV so that it is level. Insert the bolt assemblies back
into each leg so that the legs are secure and the UERV
sits in a leveled position.
18. Lift the top panel of the RTU enough to slip the top
flange of the UERV under it, lower the top panel over
the flange then reinsert screws. See Figure 11.
