3.2 ASSEMBLY OF UNITS
Mounting the unit
Insert the vibration dampers provided in the 4 slots indicated for
ceiling installation
Fasten the base unit to the ceiling or wall using the 4 slots
provided.
Ū It is recommended to use 8MA threaded bars plus screw an-
chors of adequate capacity to bear the weight of the unit,
and to prepare the positioning of the unit using 3 8MA nuts
(2 in the lower part, 1 in the upper part as shown in figure
3.1 p. 7 ) and two M8 oversized washers with a diam-
eter of 24 mm for each bar, so that the rubber anti-vibra-
tion mounts cannot deform or come out of the slot. Before
tightening the lock nut, adjust the main nut so as to assure
that the unit is properly inclined so as to facilitate condesate
drainage (figure 3.2 p. 7). To obtain the proper inclina-
tion, tilt the unit so that the intake side is slightly lower (ap-
proximately 10 mm) than the outlet side. Make the plumbing
connections to the heat exchanger and, where the cooling
function is to be used, to the condensate drainage outlet.
Use one of the two tray drain outlets, which can be seen on
the outside of the unit side panels.
Ū To connect the unit to the drainage line, use a flexible rub-
ber hose and secure it to the pre-selected drain pipe (ø 3/8'')
using a metal clamp (use the drain outlet situated on the
plumbing connection side).
