Cold Water Basin Access / Air Inlet Louver Removal:
Some maintenance procedures require access to components located in the
cold water collection basin. All maintenance procedures can be performed
from the perimeter of the tower therefore there is no reason to enter basin.
To access the basin, one of the air inlet louver frames must be removed. To
remove, loosen the thumbscrews indicated in the image below and push the
louver retaining bracket up and to the left to move out of the way of the louver
frame. Tip the top of the frame out from the tower, then remove. Louver frames
are not the same size, if more than one louver frame is removed, the original
location should be noted.
Collection basin floor has uneven surfaces and has the potential to
be slippery. Care should be taken if entering the basin.
Louver edges can be very sharp and could cut skin if proper protec-
tion is not used. Always wear gloves and sleeves when handling
louver packs.
