1.3 Scrapping of the unit
- Do not treat the unit as mixed solid waste for scrapping but take it to pieces ( waste separation).
- Refer to the specific collection points for waste of electric and electronic devices (AEE), according to the
relevant CEE RAEE 2002/95/EC, 2002/96/EC2003/108/EC regulation.
- The vacuum pump and the containers of new and used oil contain mineral and synthetic oil. Therefore the
specific regulations for scrapping have to be followed. The same procedure has to be followed for the
refrigerant gas residual in the storage bottle. The exhaust oil drained from the pump is a specific waste and
has to be collected according to the relevant regulations in force.

2.2 Preparing for use
2.2.1 Removal of load cell blocking device
Before using the unit for the first time remove the safety screw which is screwed to the tank load
cell for protection during transport(see fig. 1). It is recommended to check the regular functioning
of the load cell, for example by hooking a known weight to the bottle to check the corresponden-
ce with the weight shown on the display (see relevant paragraph).
1Rivet nut to fix the load cell during transport
2Threaded hole to fix the calibration hook to the
load cell
3Fixing bolts of the load cell
2.2.2 Oil level checking of vacuum pump

spy glass)
Ecos-150 sw 1.x.x - ver. 1.0 Page 5/20
Half of the level

2.2.3 Connection of tubes and leak test
Connect the charging hoses to the unit (high pressure = RED, low pressure = BLUE). Make sure that the
quick couplings are in position “CLOSED”.
Carry out a vacuum cycle of one/two minutes followed by a leak test under vacuum. The above procedure
avoids that air residuals are left in the hoses and checks for eventual leaks. (see the relevant instructions)
The vacuum and the following leak test the test should be repeated whenever the charging hoses could
have been contaminated with air.
Check if the setting relevant to the length of the hoses is correct (select “OPTIONS AND SETTINGS” then
“HOSE LENGTH” and modify if needed , by means of the buttons “UP” and “DOWN”
If the hose length is set to “0” (zero), at the end of the working cycle, the unit will not
calculate the gas remaining in the hoses at the end of the working cycle. The user has to
suction the gas residuals in the A/C system of the vehicle, at the en of the working cycle.
Note: in case of a pressure test which is not preceded by a standard working cycle, the user has to recover
the gas residuals in the vehicle A/C sytem, regardless to thehose length setting.
2.2.4 Filling of internal bottle
The unit is delivered with the empty internal gas bottle for safety reasons. It is therefore necessary
to fill the bottle with a refrigerant g quantity not lower than 2 Kg and not higher than eighty percent
of the maximum nominal capacity of the reservoir (this percentage may vary according to local
safety rules). In order to fill the internal tank please follow the relevant instructions of the present manual.
2.2.5 Connecting to power feeding
Connect to proper power feeding according to the unit's technical specifications
2.2.6 Position on an even surface
During the operations, the unit must be located on a flat and leveled surface in order to correclty
perform the weight measurements and in order to comply to the safety rules.

model) These counters have to be reset by the service personnel.
6.1 Filter replacement
•Avoid the refrigerant to contaminate atmosphere.
•Recover the gas residuals left in the charging hoses and in the filter
•Replace with original filters
ATTENTION! The filters have to be mounted according to the flow direction
indicated by the arrow signed on the filters itself

- In order to replace the oil, remove the screw plug (1) switch on the pump for few seconds (max 5-10
seconds!) drain the oil in a container. Screw the oil drain plug in position again and add new oil by means of
the cap (4) until you reach the normal level (middle of the sight glass) Use specific hydraulic oil only to fill
into the vacuum pump! Put the oil filling cap (4) in position and switch on the pump for a final check.
- Replace the oil of the vacuum pump every 120 working hours, or, at least, once a year. By reaching the
max working time the unit will display the message “SERVICE REQUIRED to inform that it is necessary to
perform an ordinary maintenance service on the unit
IMPORTANT : the exhaust oil drained from the pump is a special waste and as such it has to be scrapped
according to the regulations in force.
Warning: switch off the unit and unplug from electrical socket before operating on the
vacuum pump. Electrical shock hazard!
