This service station may be used by only one equipment operator, familiar with A/C and refrigeration systems and the hazards associated with refrigerants and high pressure equipment.
WORKPLACE: The equipment must be operated in the open or in a well-ventilated location (at least 1 air change per hour). The workshop has to be equipped with ventilation systems able to
CAP. 3 - SAFETY CONDITIONS 8 / 77 ENGLISH
MULTIGAS 8500 PLUS ensure the air change in every environment area or to carry out a periodical ventilation by 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.

MULTIGAS 8500 PLUS
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.

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
MULTIGAS 8500 PLUS
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.
CAP. 8 - COMMISSIONING 36 / 77 ENGLISH
MULTIGAS 8500 PLUS
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 bottle; slightly press downward the coupler ring nut to extract it.

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.
ENGLISH 41 / 77 CAP. 10 - A/C SYSTEM RECHARGE
MULTIGAS 8500 PLUS
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.

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.

ALWAYS FOLLOW THE INSTRUCTIONS ON THE REFRIGERANT
MANUFACTURER'S SAFETY SHEET IN FULL
Connect the HP quick coupler (red), in case of R134a, LP quick coupler (blue), in case of R1234yf, of the unit to an external tank by using the adapter supplied with it.
Open the coupler by turning the knob clockwise.
Open the valve on the external tank.
There are 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 bottles 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 HP gauge shows the pressure level into the external tank.
From the main menu select MAINTENANCE and press “VESSEL FILLING”.
In the following screen page set the quantity of refrigerant you wish to charge.
The field RESIDUAL shows the quantity of refrigerant being currently present in the vessel.
Position the cursor into the field TO CHARGE that will suggest, by default, the maximum quantity of refrigerant to charge.
Press START to begin the refrigerant filling phase.
Please note that when the system warns that the maximum selected weight has been reached, after the closing of the external bottle valve, the unit still absorbs a small amount of refrigerant.
In case of problems during the internal vessel filling phase, a specific message will appear on the last line of the display.
It is possible to interrupt the phase in progress at any time, by pushing the icon
After some minutes the unit will automatically end the function.
At the end the weight of the charged refrigerant will be displayed.
