Assembly of the bodies
Before beginning the assembly on site, check that all elements delivered inside the basin have been removed. To access the basin, the
bolts used to capture the angle that is used to hold the louvers panels have to be eased. Then the angle is to be removed, as well as
some panels. The angle to be removed is located in the adjacent side where the floating valve is placed. See fig. 6.

Once the lower body has been installed, the entire perimeter of the assembly flanges must be cleaned. Then, a rubber sealing gasket
(supplied) will be installed in order to avoid any damp and/or dirt, just in the centre line of the holes of the flange. If the cooling tower
has a flange without holes, then a double line of superimposed gaskets will be installed, as shown in fig. 7, in order to protect these
bodies more thoroughly.
Once the gasket has been installed, it is recommended to introduce a pointer in the holes, in order to remove any traces of the gaskets
that might be left there.
WHEN ASSEMBLING BOTH BODIES, CHECK THAT BOTH PARTS OF THE EXTERNAL PIPE ARE PLACED ON THE SAME SIDE, IN ORDER TO
FACILITATE THE INSTALLATION.
