Installations Instructions
Inspection
Upon reception, inspect the merchandise
and notify both the carrier and the insur-
ance company, in writing, of any possible
damage.
Environmental protection
Packing
Packing is made of recyclable
material. Its eliminate should be
carried out in accordance with the
existing regulations on selective
collection of residual material.
Refrigerant
Contains greenhouse effect fluorided gas
covered by the Kyoto protocol.
For the type of gas and quantity per sys-
tem, see the identification plate.
GWP (Global Warming Potential): 2107.
Elimination of the unit
Upon disassembly of the unit, its compo-
nents should be recuperated ecologically.
The cooling circuit contains refrigerant
which should be recuperated and then re-
turned to the gas manufacturer for recycling.
Oil will remain in the sealed compressor
and, therefore, must be returned with its cir-
cuit sealed. The air conditioning unit will be
deposited in an area established by the
local authorities, for its selective recupera-
tion.
Transportation
The units should always be transported in
vertical position so as to avoid oil leaking
out of the compressor. If, for any reason,
this position need be changed sporadically,
they will remain in that position a strictly
necessary period of time.
Handling
The units can be moved to their final loca-
tion by using the four rectangular holes in
the bed frame, a forklift truck or the four cy-
lindrical holes at the ends of the frame.

Warning signs
The following signs indicate the existence
of potentially dangerous conditions for
users of servicing personnel. Whenever
found on the unit, take the meaning of each
one into account.

Caution: The unit is equipped with a remote
control system and can start automatically.
Two minutes prior to having access to the
interior, disconnect the power supply so as
to avoid any contact with the fan turbine in
motion.

Location
Before opening the packing, check the
specifications described on same to be sure
you have received the adequate product.
The unit should be placed on a perfectly
horizontal plane, making sure the base can
bear the weight of the unit.
If you want to insure the absence of
vibration, the unit can be placed on a cork
or similar antivibratory base, or fastened to
its base with antivibratory plates or supports.
Figure 9 indicates the clearances and
fastening points for the location of each
model.
Fastening the unit
Before installing the unit, make sure the
structure is strong enough to bear the
weight of same.
Normally, no special supports are required.
However, if the unit is installed directly in
offices or homes, and in extreme cases, it
is advisable to use spring supports
(supplied as accessories) so as to maintain
the transmission of vibration to the structure
at a minimum.
If the unit is to be placed on the floor, a
concrete base should be prepared so as to
distribute its weight evenly.
Clearances
The installation of each unit should have
clearances for:
a) Air intake and discharge.
b) Maintenance servicing.
c) Power supply connection.
For correct operation, always respect the
minimum distances indicated in the general
dimensions diagrams with regard to
possible obstructions of free air circulation
or maintenance servicing.
Drain
The unit is equipped with a condensed
GB
water drain connection for the water
condensation formed in the coil when
operating in the winter cycle, or for emptying
the machine completely.
connections have a 28.5 mm. outer
diameter.
At outdoor temperatures of less than 5°C,
the condensed water could freeze and
obstruct the drain. It is convenient to keep
this in mind and, whenever necessary, to
install a flexible electric heater. This heater
can be connected by means of a ambient
thermostat set at, for example, 3°C, which
will connect the heater when the
temperature is below the set point.
Electrical installation
Electrical connections
The established national regulations
should be followed in all cases.
Each unit is supplied with a control box to
which the power supply will be connected
through a fused main switch or an automatic
switch.
Within this electric panel includes a phase
detector to make sure the electrical
sequence is R-S-T. Should this not be the
case, the electronic control board will not
be powered and the unit will be inopera-
tive. In this case, interchange two of the
main power supply input phases of the ma-
chine.
WARNING
Loose cables can produce over-
heating of the terminals or an in-
correct operation of the unit. A fire
hazard may also exist. Therefore, make sure
all cables are connected tightly.
Do not apply power supply to the unit, nor
put the unit into operation until all pipes
and electrical connections are finished.
Make sure the power supply is connected
to the units correctly, as shown on the wiring
diagrams.
