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.

be slippery. Care should be taken if entering the basin.
