Drain valve
The drain valve (items no. 21-27) is mounted on the filter casing (2). To
do so, slide the O-ring (21) over the buttress thread, as well as the
O-ring (24) over the thread G 3/4" of the valve (22). Now the valve (22)
is screwed tight with the O-rings to the filter casing (2). Press the flat
gasket (25) into the mount (26) and place this combination together into
the screw adapter G 3/4" (27). This complete unit now has to be
screwed onto the inch thread of the drain valve (22).
