K. Now place the fan duct on the receiving ange of the upper section (see Figure A-8); make sure the bolt
holes and the marks inside the fan duct and the receiving ange are aligned (see Figure A-9). 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-2 to verify the type of receiving ange of
your tower).
