Webasto Thermosysteme Roof-top air-conditioning system CC4E
Page 31 / 32
A viewglass is integrated into the circuit at the receiver-drier to check the refrigerant level. When
correctly filled, refrigerant will flow through the viewglass without air bubbles roughly 5 minutes after
starting the air-conditioning system. Occasional bubbles are meaningless. Replenishment is only
necessary when foam builds up.
Refrigerant is normally replenished with the refrigerant in the gaseous state. When completely
drained, the circuit must be properly evacuated before refilling with refrigerant.
b) Replenishment of refrigerant
Gaseous refrigerant may only be replenished with the compressor running and only via the system
intake side.
For gaseous replenishment of the system, the refrigerant cylinder must be upright with the valve on
top. Refrigerant is replenished via the test fittings.
6.9. Visual inspection
The system must be inspected visually as described in chapter 6.5 when the repairs are complete.
