Apex DOS mounting fail

edunn · Saturday at 12:39 PM

Hi Everyone,
I was removing the "easy punch out mounting holes" from my new Neptune Dos QuietDrive and the plastic pieces fell inside the unit. Could you please advise if it is still safe to use? I tried holding it upside down when removing the plastic pieces and they still fell inside the unit.
I appreciate your advice.

I fell into that trap too, as I’m sure the majority of people have.
All I can say is I’ve been running mine like that for a couple years and haven’t noticed an issue.

Lol, thank you SO much for the information, and making me feel better. It's up and running :)

FYI, from Neptune in case anyone else has the same issue in the future.
Neptune Support -
The mounting knockout pieces are nonconductive plastic, so they should not cause an electrical short or create an issue inside the DŌS QuietDrive.

You can try tipping the unit and guiding the pieces back out through the original mounting hole. However, if they are difficult to remove, there is no need to continue trying. Once the DŌS is mounted, the pieces should remain in place and should not cause a problem.
