M
nsure the air change in every environment area or to carry out a periodical ventilation by
e
opening the environment areas. Use the tool away from heat sources or hot surfaces. The tool
has not to be used in explosion risk environments (potentially explosive atmospheres). Before
using it, put the tool on a levelled plane and secure position, blocking it with suitable wheel stops.
Do not expose the tool to direct sunrays, heat sources, rain and jets of water. Do not smoke close
to the equipment and during operations (keep at a distance of at least 1 m).
The work area must be monitored by the operator while the equipment is operating.
ATTENTION: the R134a and/or R1234yf refrigerant fumes/gases are heavier than air and can
gather on the floor or inside cavities/holes and cause choke by reducing the oxygen available for
breathing.
At high temperatures, the refrigerant breaks down releasing toxic and aggressive substances,
harmful for the operator and the environment.) Avoid inhaling the system coolants and oils. The
exposure can irritate eyes and the respiratory tract.
ELECTRICAL CONNECTION: Connect the power cord solely to a mains supply which conforms
with the ratings on the machine's nameplate (mounted on its side). Make sure the mains socket is
grounded.
Never use the service station with a defective power cord or a different one from that supplied
with the machine; if damaged, immediately have it replaced with an original spare or equivalent
by a Brain Bee S.p.A. service centre. Before opening the service station, extract completely the
supply cable from the plug, or you can get an electric shock.
Do not tamper with or bypass the safety equipment and settings.
Do not leave the machine powered up when not in use; shut off the power supply before leaving
the equipment unused for a long time. Do not forget that the tool (pressure tool) must always be
protected.

REFRIGERANTS AND LUBRICANTS - INDIVIDUAL SAFETY EQUIPMENT AND PRECAUTIONS: The
refrigerants and the pressure vessels have to be handled with care, otherwise there will be
possible health risks.
The operator must wear safety glasses, gloves and protective clothing suitable to the work. The
contact with the refrigerant can cause blindness (eyes) and other physical damages (freezing) to
the operator. Avoid contact with the skin; the refrigerant's low boiling point (approx. –26 °C for
R134a and approx. -30 °C for R1234yf) can cause freezing burns.
Further information about safety can be obtained from the safety sheets of lubricant and
refrigerant producers.
Do not inhale refrigerant or oil vapour. Keep away from the vent valves and ventilation coupling,
especially when non-condensable gas is being vented.
Never direct the quick couplings (taps) towards your face or other persons or animals.
OTHER PROHIBITIONS AND USE LIMITATIONS: Only use pure R134a or R1234yf refrigerants,
refrain from using on vehicles containing other types of refrigerants or mixtures of the two
refrigerants or other gases. The mixture with other types of refrigerant produces serious damages
to the conditioning and cooling systems. Mixed gases have to be disposed of according to the
current regulations. Never use MULTIGAS 8500 PLUS equipment with systems containing
compressed air, mixtures of R134a or R1234yf with air or oxygen may be potentially flammable.
Do not modify the calibration of safety devices. Do not remove the seals of the safety valves and
of the control systems. Do not use external tanks or other storage containers that are not
homologated or without safety valves.
Make sure the equipment's aeration and ventilation ports are not obstructed or covered while the

8.1 CONNECTIONS
The unit has to be positioned on a horizontal surface to ensure the correct operation.
The unit has to be connected to the electric mains following instructions on the identification plate of
the unit applied next to the main switch, mainly as to applicable voltage and power.
8.1.1 Positioning and connection
HANDLING: During handling, the minimum devices required for correct
handling shall be ensured, as provided for by accident prevention provisions.
POSITIONING: Place the unit in a stable place. The location must be well
ventilated, with a good rate of change of air. The unit must be located at least
10 cm from any potential obstacles to its internal ventilation. Keep the unit away
from rain and excessive humidity as they can irreparably damage it. In addition,
the equipment must never be directly exposed to the sunrays or to excessive
dust.
INSTALLATION: the unit must be installed by a specialised technician in
scrupulous observance of the instructions given in this manual. The use of the
equipment in explosive atmosphere is forbidden.
CONNECTIONS: since the unit is connected to the main power supply, it must
be properly grounded with its power plug GND pin. Failure to ground the unit
can damage it and constitutes a risk of fatal injury to the operator. Position the
unit so that the power plug is easy for the operator to access.

8.1.2 FIRST TANK FILLING
Execute the following actions in sequence by following the display guided procedure and the
illustrations on the summary sheet provided with the equipment:
• Gas weight check
• Oil weight check
• Pressure check
• First tank filling
It is possible to interrupt the initial check and print a report with the equipment printer in which the
checking status is reported.
The equipment cannot operate in automatic mode until all the steps of the initial check have been
completed.
CAREFULLY ABIDE BY THE FOLLOWING
INSTRUCTIONS TO AVOID DANGER TO
PERSONS, THE DISCHARGE OF
REFRIGERANT IN THE ATMOSPHERE
Let us consider as first filling the one carried out during the initial check with internal tank of the
equipment free of refrigerant gas and containing air.
ENGLISH 35 / 77 CAP. 8 - COMMISSIONING
ULTIGAS 8500 PLUS
M
Set the quantity of gas to fill (at least 3 kg) and follow the guided procedure shown on the display.
Check that the equipment hoses are not connected and positioned in the hose winder. Start the
procedure that initially implies the creation of vacuum in the internal tank. This phase will take 15
minutes and will act on the whole equipment.
Only when the message appears asking to connect the recharge tank, connect the supplied HP
quick coupler (coulour red) in case of R134a or the LP quick coupler, in case of R1234yf, of the unit
to an external refrigerant gas tank using the supplied adaptor.
Open the coupler by turning the knob clockwise. Open the valve on the external tank.
Just right before reaching the planned quantity of refrigerant, the unit will stop and ask the user to
close the external refrigerant tank. Then, the device will continue the recovery from the hoses and
ends when these are empty. Hence, it is necessary to open the LP quick-coupler and disconnect it
from the external tank. Thanks to the ECO-LOCK function, the refrigerant - usually kept between the
cylinder fitting and the hose quick-coupler until the end of the process - will not be released in the
environment.
There may be two types of source tanks: with plunger and without plunger.
Tanks with plunger shall remain upright to be able to transfer liquid refrigerant; for this type of tanks
connect to the L (liquid) coupler.
Tanks without plunger have only one valve, so they must be turned upside down to transfer the
liquid refrigerant.
The LP gauge indicates the pressure inside the external tank.
After some minutes the unit will automatically end the function.
At the end the weight of the charged refrigerant will be displayed.
8.2 NEW OIL BOTTLE FILLING
The new oil bottle is on the left – looking at the unit from the front side.
To fill it, it has to be extracted from its housing by means of the quick coupler on the top of the
bottle; slightly press downward the coupler ring nut to extract it.
Fill the bottle by paying special attention to the “oil care” valve.
This valve is made of a silicon polymer membrane; it compensates pressure variations within the
bottle and stops humid air infeed inside thus preserving the new oil inside.

After filling, close the bottle and place it back in its seat.
8.3 TRACER BOTTLE FILLING
The tracer is a substance made up of a yellow-green coloured fluorescent pigment, which means
that, when lit by an ultraviolet lamp, it becomes fluorescent and thus visible.
The tracer can therefore be used to detect leaks of a small entity inside the auto vehicle A/C system.
The tracer bottle is on the right – looking at the unit from the front side.
To fill it, it has to be extracted from its housing by means of the quick coupler on the top of the

CAP. 10 - A/C SYSTEM RECHARGE
10.1 PRELIMINARY OPERATIONS
The recovery and recharge operations have be carried out after the car /AC system has run for
some time; however, an excessively hot A/C system has to be avoided since the next recharge phase
could be adversely affected by high pressures.
The vehicle must not be prepared in a special way; connecting hoses have to be attached by
identifying their position.
Vehicle details necessary for the performance of the charge/recovery/vacuum cycle are the amount
of refrigerant and the type and quantity of oil. These data are often found on the engine
compartment plate or on the technical manuals.
As to oil quantity technical manuals of cars, systems as well as available details in general indicate
the total quantity of oil in the system.
Indeed the amount of oil to be recharged is that extracted during the refrigerant recovery phase
which is very small.
FEATURES
Your new A/C service station is equipped with new ECO LOCK® quick couplers. These new couplers
offer the following functions:
1. Avoid dispersion of the gas, allowing the recovery by the tool (thus protecting the
environment and saving refrigerant).
2. Automatic leak test of the car A/C system valve at the end of the service.
After connecting the quick couplers to the (high pressure) HP and (high pressure) LP connectors of
the vehicle, screw the valves only when required by the messages on the tool display.
To recharge the A/C system, you have to know the refrigerant type and also the suitable type of oil.
These data are usually available in the vehicle user manual or on the engine compartment plate.
The car manufacturer specifications can be another source of information.
As to the oil amount, remember that technical data of the A/C systems and instructions usually
present in the vehicle show the total oil amount in the system. In the car A/C system you have to add
only the oil amount necessary to restore the amount set by the car manufacturer.

CONDENSABLE GAS
M
10.2 NON-CONDENSABLE GAS DISCHARGE
The station is equipped with the AIR PURGE SYSTEM function, which allows automatically detecting
and purging non-condensable gas (mainly air) accumulated within the tank.
Periodically, basically every week, the station, the first time it is switched on that day, will suggest
running the AIR PURGE SYSTEM procedure
If the station detects non-condensable gas in the tank, it will automatically run the non-condensable
gas discharge procedure.
Running this procedure is very important to ensure the ideal working parameters for the station
operation. The presence of non-condensable gas in the tank will increase the pressure inside the
tank and, therefore, will slow down and reduce the efficiency of recharge cycles on the vehicle.
The AIR PURGE SYSTEM function can be disabled from the setup menu. In this case, execution of the
procedure will no longer be suggested when switching on the station.
The procedure will take a few minutes, and its duration may vary according to the amount of noncondensable gas within the tank.
If needed, the non-condensable gas discharge procedure can be executed at any time from the
maintenance menu.

10.3 QUICK MODE AND ZERO TOLERANCE RECHARGE MODE
MULTIGAS 8500 PLUS can apply two different refrigerant recharge modes; the first one is called
Quick mode and features the opening of the recharge valve by injecting gas through the HP port. By
the Quick Mode part of the refrigerant remains into the hoses and is compensated by software
calculation.
Whenever the recharge is not completed the UNIT shifts automatically to the Zero Tolerance mode.
The Zero Tolerance function is the second recharge procedure, an alternative to the Quick Mode.
It features a more accurate recharge and guarantees a successful recharge (it however requires a
longer time and the operator's intervention).
If the car A/C system is equipped with both couplers or with LP coupler only, there are two slightly
different working modes; in any case if only the HP coupler is available the Zero Tolerance mode is
not applicable.
With both HP and LP couplers available the Zero Tolerance features the injection of the selected
refrigerant amount into the system through the HP hose; then refrigerant remained into the HP hose
is sucked by the car system – engine and compressor running – through LP (after disconnecting and
closing the HP coupler).
In case the LP coupler only is available the station charges the system with 50% of the selected
amount with car compressor off and waits for 10 minutes before recalling the operator. This wait
time – quite rare since most of cars are equipped with HP coupler too – allows the refrigerant
injected near the compressor – that is LP side – to evaporate to prevent any damage to the
compressor during the admission of liquid phase refrigerant. Then, after car and A/C system switch
ON recharge continues through timed injection of refrigerant through hose LP, such injections start
exclusively if the LP pressure is lower than 3 bar.

12.5 FLUSHING (with optional accessories)
After performing a lot of recharge cycles or after replacing components or parts of the /AC circuit
on a vehicle it is advisable to carry out a system flushing.
The system washing (Flushing) consists in purifying the vehicle cooling system through several
R134a or R1234yf gas flushes, by recovering it each time, so that the impurities can be filtered
little by little through the additional filter.
Thanks to its specific design, MULTIGAS 8500 PLUS can automatically manage the flushing
process so that the process becomes fully automatic.
2 flushing modes are available: STANDARD and FLUSHING KIT VAS (both with optional external
kits).
Once the (optional) flushing kit has been installed, as described in the instructions included in the
kit, and after selecting the specific function for the kit being used, start the phase, setting the
desired flushing time
In case of problems or errors during this phase, a message will be displayed, identifying the type
of error.
It is possible to interrupt the phase in progress at any time, by pushing the icon
.
12.6 PRESSURE CHECK
To check the vehicle A/C system status – for instance in case there is no flow of cold air from
flaps – pressure values can be checked.
Connect the HP - LP couplers or the single coupler to the vehicle system.
Perform the following preliminary operations on the vehicle:
• Turn on the A/C system
• Set temperature at minimum level.
• Set fan speed at maximum level; close all the flaps except the central one and set air
distribution to central position.
• Keep engine at accelerated idle at constant speed for at least 2 minutes.
• Check the pressure values within about 3 - 5 minutes.
In the MANUAL CYCLES menu, select the PRESSURE CHECK function.
Open couplers (or the single coupler) rotating knobs clockwise.
After the refrigerant injection, a check of the pressure on HP and LP sides will be requested; make
sure that both values on LP and HP gauges fall within the values shown on the display.
PRESSURE VALUES CHANGE CONSIDERABLY WHEN AMBIENT TEMPERATURE
CHANGES. KEEP THIS IN MIND WHEN CHECKING PRESSURE VALUES

valve allowing the fluid outflow from the internal vessel to the manifold, (metallic component
housing the check solenoid valves) to the compressor infeed, including the dryer filter leak test.
In case of failed leak test, it is necessary to check the charge hoses conditions and the quick
couplers leak, and make the possible repair and then repeat the test. (For the touchscreen use,
see chap. 5.8)
13.2 PRESSURE ZERO
This function allows to determine and store the atmospheric pressure value.
We recommend running this procedure every time an abnormal operation of the station is
detected, such as recovery phase taking too much time to be completed, or exhaust oil discharge
with pressure being either too high or too low.
This procedure is run automatically during the first filling of the tank.
13.3 LONG LIFE PUMP SPECIAL FUNCTION - VACUUM PUMP
OIL CHANGE
The tool is equipped with a special function named LONG LIFE PUMP that enables to optimize
the vacuum pump oil use by avoiding the replacement every 60 hours of operation.
LONG LIFE PUMP is a Brain Bee patented special function allowing to extend even to 1000 hours
the life of the pump oil used in the station.
LONG LIFE PUMP function performance is suggested at the end of 60-hour operation intervals of
the vacuum pump and can be manually activated in the MAINTENANCE menu.
LONG LIFE PUMP procedure has to be started only after checking and, if necessary, topping up
the pump oil level and lasts 1 hour: during this time the tool cannot be used.
During the procedure the oil is automatically purified from the gaseous polluting residues
absorbed during the emptying operations of vehicles air conditioning systems.
At the end of the procedure, the vacuum pump performance check is carried out and a result to
the operator is signalled.
In case of negative result you have to replace the vacuum pump oil.
After 1000 hours of vacuum pump operation since the last oil change, the LONG LIFE PUMP
procedure cannot be activated anymore and you have to replace the oil according to the
following instructions.
