Installing O-ring fittings

A
CAUTION!
z O-ring fittings must be tightened with a smaller torque than SAE fittings
because if the tightening force is too great this could damage the seal seat
and thus cause leaks!
z Always work with two spanners when tightening or releasing a connection
in order to prevent the cables twisting!
z Reusing O-rings is not permitted!
➤ Make sure that the O-ring is located on the specified fitting seat prior to commencing
installation (1).
➤ Paint refrigerant oil onto the thread and O-ring seat in the area marked with (*).
➤ Fasten the related connection thread by hand (2 and 3).
➤ Tighten the connection with two spanners.
