Oil charging
IMPORTANT! When the A/C unit has been charged with refrigerant, oil
charging is not possible. Oil charging must always be performed before
refrigerant charging.
Oil charging is only possible after evacuation is complete and only when the lamp
VACUUM OK (pos. 18) lights up.
Proceed as follows:
-
Check to make sure that there is sufficient oil in the oil tank or replenish the
tank as described below.
-
Press the oil charging switch and observe the level in the oil tank (pos. 2)
until the quantity required has been sucked into the A/C unit.
-
The A/C unit is now ready for refrigerant charging. See instructions for
refrigerant charging.
Oil tank replenishment
When the level in the oil tank has reached the lower edge of the scale, oil
replenishment is necessary. Simply remove the oil tank cover and refill with oil.
