Vertical air discharge conversion for VCH 45A,
60A 75A and 90A
This Kit allows converting the standard horizontal air dis-
charge, in outdoor units VCH 45A to 90A, to a vertical dis-
charge. The conversion process is as follows:
1.- Remove and discard the upper panel 1 and the grids 2
(Fig. 1).
2.- Remove the fan, standard motor assembly on support "A"
(Fig. 2).
3.- Change the motors and their supports, the fastening rods,
the support and nuts to B in the 8 diameter drilled holes
proportioned at the limits indicated, making sure the pul-
leys are aligned (the centre of the tensor will be at about
20 mm. from the face of the fan) (Fig. 3).
4.- Fasten the fan to the tabs "C" and supports "D" of the
upper panel 3 , before or after mounting same on the
machine, with the new self-threading screws included in
the Kit (Fig. 3).
5.- Install the upper panel 3 and the plenum cover 4
(Fig. 4).
6.- If the machine is to be used without ducts, install, in the
fan mouths, the protecting grids supplied with the Kit
(self-threading screws are included for assembly).
