J. Remove fan guard. Then cradle/straddle the fan support with the straps (as shown in gure A-16) so you
can lift the fan duct with a crane and assemble it.
K. Identify each fan duct, they are labeled with a number on the inside of the lower edge. For a correct
installation, this number must match the number on the receiving ange. Now place fan duct 1 on the
correspondent receiving ange on top of the tower (see Figure A-16); make sure the bolt holes and the
marks inside the fan duct and the receiving ange are aligned (Figure A-17). Secure it with the stainless
steel nut and bolt sets supplied by REYMSA. There are two different types of receiving anges, each one
has its own assembly pieces (see Table A-3 to verify the type of receiving anges of your tower).
L. Follow the same instructions to place fan duct 2.
