• The body section should then be lifted and carefully position to align the support post of the sump
with the corresponding groove of the tower body. Note that the four corner posts are slightly higher
than other post to ease installation alignment.
• Set one end of the tower body onto the corner post at one end of the sump first. This can be
accomplished by use of a rope tether attached to the lifting bar at one end of the housing. Continue
setting and aligning support post along the sides of the tower moving from one end to the other. This
step may require a couple installers to align multiple posts simultaneously. You may use a rubber mallet
or blocking wood to aid aligning post.
IMPORTANT: Make sure that all posts are correctly seated into the pocket of the tower body.
• For single cell units, the four corner sump posts should then be secured to the main housing with the
provided stainless steel angle brackets and hardware. On Multi-cell towers, the outermost four corner posts
should be secured to the main housing with the provided stainless steel angle brackets and hardware.
• Before installing PVC louver panels, verify that all post are correctly seated into the pockets of the tower
body.
• Install PVC louver panels between each support post. Panels are numbered and marked on top of each
panel, and should be installed with corresponding numbered window opening. Insert bottom of panel into
window opening and work your way up to the top. Panels should be mounted flush with inside top of louver
opening inside tower and should direct incoming air downward. Secure panels with self-tapping screws
provided.
