CALIBRATING THE OIL SCALE

From the CALIBRATION MENU:
Select OIL SCALE and the following screen is displayed:
Empty the oil containers. Replace the empty containers in their lodgings, taking care not to
exert pressure on the scale, and press START. The following screen will be displayed:
Fill the new oil container with a known volume of new oil (from 100 a 250 cc measured on the
container measure marks). Replace the container in its lodging, taking care not to exert
pressure on the scale. Use keys 0 through 9 to type in the known oil volume, in cc, and press
START. Switch off the machine and disconnect it from the electrical supply.

CALIBRATION THE A/C PRESURE

Warning: This operation must be carried out only with the front service hoses empty. We
recommend running a brief RECOVERY phase before beginning calibration. Slowly unscrew
the blue front service hose, open the front taps, and check that both pressure gages read 0
bar. Switch the machine on. From the CALIBRATION MENU:
