reverse. When fastening the motor mount mechanism to the torque tube,
first insert the fasteners closest to the access panel that acts as a hinge.
After tightening this hardware, swing the motor in and attach it to the torque
tube. Due to the weight of the motor cantilevered on the hinge, the motor
mechanism may sag. When attaching to the torque tube, it may be neces-
sary to align the holes with the jacking screw shown in the image.
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 basing floor has uneven surfaces and has the potential to
be slippery. Care should be taken if entering the basin.
