Mounting instructions:

  1. Insert the coil from the service end and co-align the coil housing (1) with the end of the gradient tube.
  1. Switch the valve (2a) in the “pump” position.
  1. Gently pump and inflate the rings (2c) of the pneumatic fixation system using the balloon (2b).
  1. Connect the coil with the corresponding RF interface socket according to the color labels.

 

To remove the coil from the magnet, proceed as follows:

  1. Stop any running scan prior to disconnecting or dismounting a RF coil.
  1. Unplug the coil using the leverage effect of the coil socket cover.
  1. Open the valve of the pneumatic fixation system.
  1. Remove the coil out from the gradient bore.

 

NOTICE
The components of the pneumatic fixation system can easily be damaged.
  1. Never pump and inflate the rings of the pneumatic fixation system outside a surrounding bore to avoid exceeded inflation and damage of the system.
  1. Do not apply high pressure to the components of the pneumatic fixation system. Gently pump by hand.
