Installation instructions
General description
The ASAO/I model conditioners are supplied in standard
form as separate units. They are designed for installation
with ducting, on terraces, roof-tops, in lofts and basements.
When necessary, and at the moment of installation, these
two units can easily be joined together, transforming them
into a compact set of equipment.
Control of stopping and starting and temperature regulation
are carried out through a special 24V thermostat which is
supplied with every ASAO outdoor unit.
Protection of the environment
Packing
Packingismadeofrecyclablematerial.Thedisposalofsame
should be carried out in accordance with the regulations on
selective residue disposal established by the local authori-
ties.
Disposal of the unit
When dismantling after a long service life, its components
should be ecologically salvaged. The cooling circuit is full of
HCFC-22 refrigerant which should be salvaged and, finally,
returned to the gas manufacturer for recycling.
Oilwillremainintheairtightcompressorso,itwillbereturned
along with the sealed circuit.
The air conditioning unit will be deposited wherever estab-
lished by the local authorities for its selective disposal.
Warning signs
The following signs indicate the presence of potentially
dangerous conditions for the users or service personnel.
Whenever found on the unit itself, keep in mind the warning
indicated by each one.
Attention: It is compulsory to read the
instructions prior to any handling.
Attention: Not to touch the hot surfaces.
This sign indicates an electrical risk or
danger.
Attention: The unit has a remote control
system and can start automatically. Two
minutes prior to having access to the inte-
rior, the power supply should be discon-
nected so as to avoid any contact with the
fan turbine in operation.
Attention: Wheel and belt transmission.
Attention: Possible escape of gas if incor-
rectly handled.

should be left for filing the trap with water at the beginning of
each season.
The drain line must have a minimum slope of 2 cm. for each
metre of length.
The connections on the apparatus are of steel tube with
3/4" G. interior thread.
Location
Thelocationmustbechosenprovidingpermanentaccessfor
maintenance service, both through the lateral and rear
panels.
The outdoor unit can be installed directly out doors. If it is
installed indoors, in basements, lofts, etc., ducting must be
fitted to bring in exterior air and for its extraction.
Clearances
In the installation of each apparatus, clearance must be left
for:
a) Intake and discharge of air to and from the outdoor unit.
b) Connection of drain and electrical tubing.
c) Air ducts.
d) Maintenance service.
e) Electrical wiring.
f) Cleaning the filters
On-site modifications
Iftheinstallationconditions require it, the discharge from the
indoor fan ASAI can easily be modified on site to provide
discharge vertically.
Air ducts
1- Connect the ducts, insulating them from the apparatus
with a flexible coupling, preferably of non-inflammable
material,toavoidtransmissionofvibrationfromtheappa-
ratus itself. If the ducts are made of flexible material they
will not transmit vibration.
2- Itisrecommendedthataregisterbefittedoneachsection
of the ducting to ensure correct balance of the system.
3- Leave easy access for cleaning and changing the air
filters.
4- With the ASAO-45 units, two separate ducts, one from
each fan, to the discharge, must be fitted to avoid
recirculation of air.
Drain connections
Run the drain tubes for each pan though a trap. Leave a
minimumleveldifferenceof75mm.betweentheheightofthe
connection to the apparatus and the line after the trap (see
drawing). This is to prevent the depression produced by the
fan from interfering with the emptying of the pan. Access

Compact installation of the units
The units are supplied prepared for connection of their
cooling circuits and electrically.
To install the units as a compact system, the outdoor ASAO
unit and the indoor ASAI one have to be joined through the
holesprovidedinthembythescrewsprovided.Thesewillbe
found in a bag inside the electrical box in the ASAO-60 and
in the indoor unit in the ASAI-25, 30 & 45.
The indoor and outdoor units are supplied with the cooling
circuit connections ready for soldering and to be intercon-
nected on the outside of the casing.
The ASAO/I-25 and ASAO/I-30 units have one sole circuit.
The ASAO/I-45 and ASAO/I-60 units has two circuits.
And the refrigerant load should be applied onsite.
Charge process
1 - Depressurise the units.
2 - Drain the refrigerant.
3 - Clean out with dry nitrogen.
4 - Solder the tubing under dry nitrogen inside the tubes.
5 - Forsolderinguselowmelting-pointrodswithaminimum

When forming the tubing to join the two units special care
shouldbe takentokeepthetubes cleananddryevenbefore
installation. The following recommendations should be ob-
served:
1 - Use only copper tubing of refrigerant quality.
2 - Do not carry out outdoor work if it is raining.
3 - The ends of the tubes should be kept closed during the
installation.
4 -The dryer filters and compressor should not be left
exposed to the elements for more than one or two
minutes.
5 - For soldering use low melting-point rods with a minimum
silver content of 5%.
6 -During soldering and for as long as the tube stays hot, a
current of dry nitrogen should be kept up to avoid the
formationofoxideswhichcouldcausecontaminationand
blockage.

Insulation of tubing
The interconnecting cooling tubing must be insulated.
The insulation requires certain characteristics: it must be
easy to install; be hard-wearing; be water and fire resistant;
and have a minimum thickness of 12 mm.
To avoid deterioration through exposure to sunlight it is
recommended that it be painted with water-enamel.
Electrical installation
Each conditioner is delivered with a control box for connec-
tion to the mains through a main switch with fuses or an
automatic cut-out.
The electric heater, if there is one, must be installed with
power line and switches independent of those of the condi-
tioner.
In all cases established national regulations must be
observed.

Operating instructions
General information
Start-up and automatic temperature regulation are carried
out through the ambient thermostat.
Place the thermostat about 1.5 metres above floor level,
where no obstacle can prevent it from measuring the real
temperature of the room.
Important warning
The thermostat should be located on a wall that is not
exposed to direct sunlight. Should this not be the case, the
temperatures would not be real, and operation would be
inadequate.
Before starting up, turn on the main switch to activate the
electric heater in the compressor crankcase.
The compressor must not be started up until at least
eight hours have elapsed.
Thisistoallowforevaporationofanyrefrigerantinliquidform
which may have mixed with the compressor oil.

Recommendations for better functioning
- Turn the console on before the room gets hot. The heat
accumulated on furniture, walls, etc. makes the console
take longer to achieve the desired temperature.
- Itis advisabletoinspect andserviceyour unitinthe spring;
this avoids damage and insures a long sevice of your
console.

Pressostats
The conditioner is fitted with a cut-out in the high circuit,
functioningwhen pressurebecomesexcessive, andanother
in the low circuit, when it is insufficient. When one of the cut-
-outs is activated, it opens the control circuit, stopping the
compressor.Beforere-settingthecorrespondingcut-out,the
thermostat should be switched off through the thermostat

fit this protection could result in damages being caused by the fan
turbine.
Cleaning the filters
Keep the battery filters in good condition, servicing them at
leastonceamonth.Ifthefiltersbecomedirtytheywillreduce
the air-flow and the performance of the unit.
Cleaning the outdoor unit
Dirt must not be allowed to accumulate on the outdoor unit.
This must be cleaned as often as necessary with a brush,
Attention:Theunit has a remotecontrolsystem and can startautomati-
cally. Two minutes prior to having access to the interior, the power
supply should be disconnected so as to avoid any contact with the fan
turbine in operation.
Forsafetyreasons,makesuretoturnyourairconditioneroffandunplug
the mains before any cleaning is performed or fan motor belts are
checked.
Access to the units for maintenance servicing
Check the outdoor unit periodically to see whether either the outlet or
the inlet are blocked up with dirt or leaves, etc.
The internal coil and other components of the outdoor unit must also
be periodically cleaned. Contact your concessionary or maintenance
service.
For safety reasonts make sure you switch off the air-conditioner, and
disconnect it from the mains before cleaning.
Filling the drain trap
Toavoid problemswithwatercondensation,we recommend
thatatstart-up and beforethebeginningof each season,the
drain trap be filled with water, to prevent air being drawn
through this tube from the beginning.
Checking belt tension
The tension and wear of the motor belts should be checked
onceayear,andmustbechangedifnecessary.Beforedoing
this, turn the general main switch off.
