1. Prior to evacuating, check if the filter receiver drier
has to be replaced.
Checking the filter receiver drier:
In the control window (G), the ball will indicate the
condition of the filter receiver drier.
Blue = OK
Pink = Requires replacement
The filter receiver drier must also re replaced
following a major leak, e.g. a broken line, in the
refrigerant circuit.
2. Prior to filling, the air conditioner system must be
evacuated and the tightness must be checked.
3. Topping up refrigerant:
Fill in refrigerant at connections (D, discharge
side) and (S, suction side) of the air conditioning
compressor.
ATTENTION!
Never fill in liquid at connection (S)!
Use refrigerant R134a exclusively. The required
filling quantity is 1800 g of refrigerant. (Observe
the instructions given by the unit manufacturer.)
4. Checking the refrigerant level at the control
window (G) of the filter receiver drier using the
white float:
If the float is at the bottom, the system requires
refrigerant.
The white float is at the top = refrigerant quantity
OK.
CAUTION!
The correct refrigerant level should be checked
directly after the system function has been
tested. Should the system have been left for a
long time, then it may appear as if it requires
refrigerant, but actually the level is correct.
