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 system,
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 returned to
the gas manufacturer for recycling.
Oil will remain in the sealed compressor
and, therefore, must be returned with its
circuit sealed. The air conditioning unit will be
deposited in an area established by the local
authorities, for its selective recuperation.
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 prod-
uct.
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 vibra-
tion, 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 fas-
tening points for the location of each mod-
el.
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 (sup-
plied 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 gen-
eral dimensions diagrams with regard to
possible obstructions of free air circulation
or maintenance servicing.
Drain
The unit is equipped with a condensed wa-
GB
ter drain connection for the water conden-
sation formed in the coil when operating in
the winter cycle, or for emptying the ma-
chine completely. These connections have
a 28.5 mm. outer diameter.
At outdoor temperatures of less than 5°C,
the condensed water could freeze and ob-
struct 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 ther-
mostat 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 auto-
matic switch.
Within this electric panel includes a phase
detector to make sure the electrical se-
quence is R-S-T. Should this not be the
case, the electronic control board will not
be powered and the unit will be inoperative.
In this case, interchange two of the main
power supply input phases of the machine.
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 wir-
ing diagrams.
