• Snap the connector into place and guide the
cable to the compressor module.
6-cylinder compressors 6JE-22Y .. 6FE-50(Y):
• Remove the sealing plugs from the connect-
ors marked by rectangles and clean the
threaded bores.
• Screw the enclosed screwed nipple (low pres-
sure transmitter) resp. T-piece (high pressure
transmitter) with Schrader valves into the
threaded bores.
• Then screw the high pressure transmitter
(2CP5-71-47) into place at the HP position
and the low pressure transmitter
(2CP5-71-49) at the LP position (tightening

Schrader valve from opening!

ule.
