Warranty
Warranty is based on the general
terms and conditions of the
manufacturer. The warranty is void
if the equipment is repaired or
modified without the written
approval of the manufacturer, if the
operating limits are exceeded or if
the control system or the electrical
wiring is modified. Damage due to
misuse, lack of maintenance or
failure to comply with the
manufacturer's instructions or
recommendations is not covered by
the warranty obligation. If the user
does not conform to the rules of
this manual, it may entail
cancellation of warranty and
liabilities by the manufacturer.
Maintenance contract
It is strongly recommended that you
sign a maintenance contract with
your local Service Agency. This
contract provides regular
maintenance of your installation by
a specialist in our equipment.
Regular maintenance ensures that
any malfunction is detected and
corrected in good time and
minimizes the possibility that
serious damage will occur. inally,
regular maintenance ensures the
maximum operating life of your
equipment. We would remind you
that failure to respect these
installation and maintenance
instructions may result in
immediate cancellation of the
warranty.
Training
To assist you in obtaining the best
use of it and maintaining it in
perfect operating condition over a
long period of time, the
manufacturer has at your disposal a
refrigeration and air conditioning
service school. The principal aim of
this is to give operators and
technicians a better knowledge of
the equipment they are using, or
that is under their charge. Emphasis
is particularly given to the
importance of periodic checks on
the unit operating parameters as
well as on preventive maintenance,
which reduces the cost of owning
the unit by avoiding serious and
costly breakdown.

Ductwork connection
Tables 6-7 list all the possible
connections.
Ducts must be connected to spigots
by means of duct tape. They must
never be screwed. Make sure that
the entire spigot surface area is
covered. Push the duct as far as
possible onto the spigot towards
the unit to get the best air tightness.
All open spigots should be
connected to ceiling grilles or
diffusers using normally equal duct
runs to minimize the damping
requirements at the grilles. Unused
spigots must be sealed. To ensure
maximum performances of the unit,
the ductwork must be as short as
possible, with a minimum number
of bends.
