Replacing Airlock Critical Components (cont.)
Airlock Pads:
17. While the housing is disassembled, inspect the airlock pads (2) located in each half of
the housing. If damaged, they must be replaced. (pic 15)
18. Remove the pads from the housing. (pic 16)
19. Inspect the O-rings on both pads. Replace if worn or damaged. Before installing new
O-rings (or re-using existing ones), apply a thin coat of Dow-Corning 33 lubricant.
(pic 17)
20. Make sure that O-rings are seated properly in the pads. (pic 18)
21. Carefully install the pads into the airlock housing. Fully installed, they will be flush
with the housing walls, with no part of the O-rings showing. (pic 19)
22. Reinstall airlock assembly onto the PHX-150 by reversing steps 1-11. (text box)
