Purge Air Hose
Connection
The hose between the purge valve unit and purge connection must be maximum
10 meters, but can be cut to required length. If the hose needs cutting, make sure
that the end with the orifice inside the hose is not cut off. This is also marked on the
hose. The hose must not be joined in a manner which will restrict the air supply.
