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

surface.
• Apply a new seal, paying attention to the
guide pin positions!
• Use new screws to fasten the solenoid valve.
Alternately tighten the screws (tightening
torque 80 Nm).
