4.1 Mounting the extension kit "Capacity
control" (CRII) and "Start unloading" (SU)
Information
In order to allow the solenoid valves for capacity
control (CRII) and start unloading (SU) to be
mounted, the corresponding CRII and SU cylin-
der heads must already be pre-installed on the
compressor.
For safety references and installation descrip-
tions for the CRII or SU cylinder heads, includ-
ing mounting positions and exact equipment of
the cylinder banks, see Technical Information
KT-101 and KT-110.
▶ Remove the oval flange and seal from the CRII/SU
cylinder head and clean the sealing surface.
▶ Apply a new seal, paying attention to the guide pin
positions!
▶ Use new screws to fasten the solenoid valve. Altern-
ately tighten the screws (tightening torque 80 Nm).
