VI.
Re-installing the compressor side panels
Once the compressor is cleaned you will need to re-install the compressor side panels.
Because of the large number of screws on the panels it will be important to start but not
tighten completely each screw to assure that the panels are aligned. This will avoid the
screws to be stripped and the PEM nuts on the frame to be damaged
1.
Hang the side panels to the compressor frame
2.
Start but do not tighten each of the 16 screws holding up the side panels (see Figure 7).
Figure 7. Start but do not tighten all of the screws holding up the side panels
3.
Once all the screws have been started and the side panel is aligned, start tightening every
screw until tight.
The Routine maintenance is now complete and the system can be re-started.
