Vacuum pump  oil change

 

  

After 60 hours of runtime (or 1000 hours if the Long 

Life  Pump test is completed successfully), the 
vacuum pump oil  must be replaced.

 

 

1. 

Disconnect ACX2180H from power. 

2. 

Using a flathead screwdriver, rotate the front locking 
screw and lift the front housing.

3. 

Place a bowl under the vacuum pump oil drain hole.  
Remove the upper filling plug and the lower drain plug to 
allow the oil to drain from unit. 

4. 

Once the pump has been emptied, reinstall  the  lower 
drain plug. 

5. 

Fill the pump with new oil through the upper fill port using 
a funnel if needed.  Fill until the oil appears halfway up the 
oil level inspection window. 

6. 

Once  the pump  has been filled, reinstall the upper fill 

plug.

 

7. 

Close front housing and secure locking screw.

 

8. 

Connect to power and turn on.

 

9. 

From the 

MAINTENANCE 

menu, press 



until 

PUMP  OIL  REPLACEMENT 

is highlighted and press 

arrow.  Press the RESET key to set the counter. The level 
and clearness of the vacuum pump oil can be checked by 
removing the rubber plug located on the front-left side of 
the unit.

Replace filter dryer

 

 

 

Unit operation is disabled at the end of the filter service life. 
Each filter is marked with a unique code. This code must be 
entered when replacing the filter. It is not possible to operate the 
ACX2180H if the same code is re-used. It is advisable to keep a 
supply of filters in stock to avoid downtimes due to the unit being 
disabled. 

 

The ACX2180H is disabled once 90kg (198lb) of R134a 
refrigerant has passed through the filter. A new filter must be 
installed and its unique code entered in the ACX2180H before 
vehicle A/C service can be performed.

3/8” 

(35mm) wrench. 

6. 

Remove the filter 

7. 

Insert a new filter 

8. 

Tighten the filter to 74 ft-lbs (100N-m) 

9. 

Carefully close front housing and 

secure locking screw. 

10. 

Allow unit to perform the automatic 

leak test requested by the software 
when unit loads

Warning - Risk of frostbite from escaping 
refrigerant

 

Refrigerant causes severe frostbite on the 
skin.

 

Check the service hoses for damage.

 



Firmly connect the service quick-release 

couplings to the service hoses.
