4. Install the SCR Cooling Manifold to the Inverter Cooling Manifold using the two (2) M6x20
fasteners. Torque to 7 Nm (62 in.lb.).
5. Secure the insulation onto the backside of the SCR Cooling Manifold.
6. Remove the backing material from the cooling manifold of the new Inverter.
7. Install all 20 M6x30 fasteners into the Inverter assembly. This will aid in the alignment when
lowering it onto the compressor housing.
NOTE
It is recommended that the new fasteners supplied with the kit be used to ensure to ensure proper torque is obtained.
8. Carefully install the Inverter on the compressor housing with the SCR temperature sensor cable
(if equiped) run on top where the SCR cooling manifold meets the Inverter Cooling Manifold.
9. Torque the M6x30 Inverter fasteners in a diagonal pattern to 3 Nm (27 in.lb.) on the first pass
then to 8.5 Nm (75 in.lb.) on the second pass. Refer to "Figure 4-229 Inverter Fastener Locations
- TTS300/TGS230".

10. Leak test and evacuate the compressor in accordance with standard industry practices.
11. Connect the SCR temperature sensor (if equiped), discharge P/T sensor, IGV motor connection,
and the suction P/T sensor.
