NOTE
Do not completely remove the foam insulation, only pull back what is needed to access the two (2) fasteners.
4.19.3 SCR Cooling Manifold Specific Removal Steps - TTS/TGS/TTH/TGH (Except TTS300/TGS230)
1. Remove the Terminal Block Assembly. Refer to Section 4.11.2 3-Phase Main Voltage Input Terminal
Block Removal and Installation on page 102.
2. Remove the DC Bus Bars and Capacitor Assembly. Refer to Section 4.21.3 DC Capacitor Bus Bar
Assembly Removal and Installation on page 168.
3. If the SCR Cooling Manifold is to be replaced, remove the SCRs. Refer to Section 4.18.3.3 SCR Removal -
TTS/TGS/TTH/TGH (Except TTS300/TGS230) on page 150.
4. Remove the four (4) M6x35 SCR Cooling Manifold fasteners that secure the SCR Cooling Manifold to the
Inverter Heat Sink Plate. Refer to Figure 4-171 SCR Cooling Manifold Removal for this and the following
step.
5. Remove the SCR Cooling Manifold.
NOTE
Removal of the SCR Cooling Manifold will require the manifold to rocked back and forth to disengage it from the SCR Manifold Return
Brass Fitting. If necessary, use a flat-blade screwdriver to gently pry the manifold upward. Use extreme caution to not damage any of the
components.
Figure 4-171 SCR Cooling Manifold Removal
NOTE
Figure 4-171 SCR Cooling Manifold Removal illustrates a TTS350 compressor. The removal and installation process for TTH/TGH
compressors is the same, with the exception of the SCR Temperature Sensor as that is not used on the TTH/TGH compressors.
