ULTIGAS 8500 PLUS
13.1 SELF LEAK TEST
In the main menu select MAINTENANCE and press “SELF LEAK TEST”.
A leak test is carried out on the internal components of MULTIGAS 8500 PLUS .
This phase includes:
• Hoses emptying
• Vacuum test
This test allows to check the tightness of the internal circuits of the CLIMA tool from the solenoid
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.
Required equipment:
1 Medium-sized cross-tip screwdriver
1 Medium-sized flathead screwdriver
1 Hex key (10 mm)
For replacement, comply with the instructions outlined below:
