Connecting The Air Hoses - Graf grey2clean Anleitung Für Den Einbau

6. Connecting the air hoses

An air hose with an inner diameter of 19 mm must be connected to the compressor. This hose must be
routed to the tank through an empty pipe. Inside the tank, the hose must be connected to the pipe aera-
tors (Y-piece)
For this purpose, we would recommend the GRAF empty pipe seal made from PE foam (item no.
107887). Alternatively, PU foam can be used.
6. Connecting the air hoses
Once the hoses have been laid and connected, the empty pipe must be
sealed in order to prevent gas exchange between the tank and the sur-
roundings of the cabinet (moisture, odours).
