WARNING:

Do all the operation in a clean and dry ambient.

1. Set-up the camera control: the best is to use a PC (via ETH cable or WIFI through the

WIFI dongle on USB FS port)

2. power on the camera and wait for boot completion

3. remove the three screws that fix the metal ring around the optical window, then remove

the ring

WARNING:

Before removing the metal ring take note of its orientation with respect to the

camera: after the filters mounting it must to be positioned as it was originally in order to

maintain the correct parallelism between the CCD and the Telescope optics.

4. before opening the air valve to remove the vacuum, always insert the vacuum pump into

the camera air valve and make vacuum on the connecting tube: using the vacuum pump

to fill air into the camera helps to avoid the air water vapor to condensate into liquid water

inside the camera

5. open the air valve

6. remove the vacuum by lightly pressing the button below the nose of the vacuum pump

7. remove the optical window and the o-ring. Depending on the camera release date, there

could be one o-ring between the metal ring and the optical window: if present remove it,

then carefully remove the optical window, and finally remove the o-ring under it, so that

you can access the filterwheel.

Each filter is blocked by one or two plastic caps fixed by a screw and if needed also a plastic

ring, depending on the filter's thickness; refer to the following picture to select the proper way to
