Dear garage owner,
Thank you for having chosen one of our instruments for your workshop. We are
certain that it will give the utmost satisfaction and be a notable help on the job.
Please become fully familiar with the instructions in this user’s manual. It should
be kept ready to hand for consultation whenever required.
AC690PRO is an electronic unit for recovery, recycle, vacuum and charge of A/C
systems using R134a as refrigerant.
A simple but reliable connection system guarantees a safe work during all of the
operations: refrigerant recovery and recycle; vacuum and leak test; additive and
lubricant injection; circuit recharge and working pressure test.
The refrigerant flow is controlled and managed by an electronic scale so as to prevent
any tank overflow or the flow of a refrigerant quantity exceeding that allowed.
The quantity to be charged in the A/C system is set by the operator by the function
keyboard or by consulting the internal database.
A patented separator still allows to separate the refrigerant from the lubricant.

OPERATING INSTRUCTIONS 49
GENERAL INFORMATION FOR THE USER
Disposing of equipment
Do not dispose of this equipment as miscellaneous solid municipal waste but
arrange to have collected separately.
The re-use or correct recycling of the electronic equipment (EEE) is important in
order to protect the environment and the wellbeing of humans.
In accordance with European Directive WEEE 2002/96/EC, special collection points
are available to witch to deliver waste electrical and electronic equipment.
The public administration and producers of electrical and electronic equipment are
involved in facilitating the processes of the re-use and recovery of waste electrical
and electronic equipment through the organisation of collection activities and the
use of appropriate planning arrangements.
Unauthorised disposal of waste electrical and electronic equipment is punishable by
law with appropriate penalties.
Disposing of batteries
Batteries must be recycled or disposed of properly. Do not throw batteries
away as part of normal refuse disposal.
Do no throw batteries into open flame!

1.0 - FOR A SAFE USE AC690PRO
The advanced technology adopted in the design and production of the AC690PRO make
this equipment extremely simple and reliable in the performance of all procedures.
Therefore, the user is not exposed to any risk if the general safety rules reported below
are followed with proper use and maintenance of the equipment.
NOTA BENE:
This unit can be exclusively used by professionally trained operators who have to know
the principles of refrigeration, refrigerating systems and gases and the possible
damages which might be caused by pressurized equipment.
Every user has to read carefully this manual for a correct and safe use of the
equipment.
1.1 - For a safe use
It is necessary to wear suitable protections such as goggles and gloves, the
contact with the refrigerant can cause blindness as well as other injuries to the
operator. Please make reference to the symbols below:
Carefully read the instructions.
Do not use open air in case of rain or high humidity.
Use gloves.
Use protection goggles.
Avoid the contact with the skin, the low boiling temperature (about -30 °C) may
provoke freezing.
Do not inhale refrigerating gases fumes.
Before connecting the AC690PRO unit to an A/C system or to an external tank,
make sure all the valves are closed.
________________________________________________________________________________ AC690PRO en
OPERATING INSTRUCTIONS 51
Ensure that the phase has been completed and that all valves are closed before
disconnecting the unit AC690PRO. This will prevent release of the refrigerant into
the atmosphere.
Do not change the safety valve or control system settings.
Do not use external tanks or other storage tanks that have not been
type-approved or that lack safety valves.
Never leave the unit live if an immediate use is not scheduled, stop the electrical
supply before a long period of unit inactivity or before internal maintenance
interventions.
Be careful while servicing the unit since connecting hoses may contain pressurized
refrigerant.
Do not use the unit in explosive environments.
Extraordinary maintenance interventions have to be performed by authorized staff only.
Pressure of leaks of the HCF-134a service equipment or of the air conditioning
systems of the vehicle must not be tested by using compressed air.
Some air/HCF-134a mixtures can burn at high pressures. These mixtures can be
dangerous and may cause fires or explosions and subsequent injuries or damages.
Further information on the operators’ health and safety can be obtained from the
refrigerant producers.
1.2 - Safety devices
The AC690PRO is equipped with the following safety devices:
Overpressure valves.
Besides the overpressure valve a maximum pressure switch has been fitted
which stops the compressor in case of excessive pressure.
CAUTION:
Any type of tampering with the safety devices mentioned above is
hereby prohibited.
en AC690PRO ________________________________________________________________________________
52 OPERATING INSTRUCTIONS
1.3 - The work environment
The unit has to work in a sufficiently ventilated environment.
CAUTION:
Work far from free flames and hot surfaces; at high temperatures the
refrigerant decomposes freeing toxic and aggressive substances
which are noxious for the user and the environment.
For a correct functioning the unit has to work on an even surface; during short
handling do not shake it.
Do not subject the AC690PRO unit to vibration.
CAUTION:
While operating do not disperse the refrigerant in the environment.
Such a precaution, besides being required by the international rules
for the environment protection, is necessary to prevent the possible
presence of refrigerant in the working environment from making it
difficult to detect possible leaks.
Work in environments with sufficient lighting.
Avoid inhalation of the refrigerants and oils in the A/C systems. Exposure may
cause irritation to eyes and the respiratory tract. To remove R134a from the
A/C system, use only the special recycling-units for R134a. If the refrigerant is
accidentally released into the atmosphere, ventilate the work area before resuming
service.
Do not use the unit under direct sunrays; sun exposure can cause excessive
temperatures and malfunctioning. Working temperatures indicated refer to the unit
being not directly exposed to the sun.
1.4 - Tank test
The tank has to be re-tested or substituted every 10 years. Check the re-testing
date (1) written on the neck of the tank.

OPERATING INSTRUCTIONS 53
2.0 - INTRODUCTION TO THE UNIT
The AC690PRO unit fits all of the air-conditioners functioning with R134a refrigerant
located on cars, trucks and industrial vehicles.
The AC690PRO unit microprocessor allows the managing of all functions by means of
an electronic scale, a LCD to display the weight or minute values and the help
messages of the various procedures which can be set, a control board with
alphanumeric keyboard.
By connecting the AC690PRO unit to an A/C system the refrigerating gas can be
recovered and recycled to enter the system itself again after a correct vacuum.
The amount of lubricant taken from the A/C system during the recovery can be
measured and, afterwards, reintegrated in the system.
The unit is equipped with a two-stage pump for high vacuum and a manifold set to
continuously monitor the operations in process.
Tightness test on the A/C units is carried out through the manometers the unit is
equipped with.
The unit is equipped with special connectors to avoid cross-mixing with systems using
R12.
CAUTION:
Do not try to adapt this unit for air conditioning systems using R12.

4.0 - INSTALLATION OF THE UNIT
Please find below operations to perform to start the unit.
4.1 - Unpacking and checking components
Remove the machine packaging.
Check to ensure that all of the accessory components are present:
Operating instructions.
1 Graduated beaker.
2 cylinder connectors.
Bottle safety valve conformity certificate.
4.2 - Machine handling and storage
Remove the unit from the base pallet of the packaging.
The unit is moved on the four wheels. The two front wheels have brakes.
On rough terrain, the AC690PRO can be moved by tilting it and balancing the weight on
the two rear wheels.
In spite of the fact that the heaviest components have been assembled on the base in
order to lower the centre of gravity, it has not been possible to eliminate the
risk of overturning completely.
