Replacing
the External Filter
Step
Description
1
Turn off power.
2
Grasp the filter housing and rotate the top back and down, twisting the filter out of the mounting clip. Use
caution as the clip has high force. Do not pull the filter away further than 2” (50 mm) from the back of the
instrument. If the tubing becomes taut, move the filter closer to the instrument.
3
With the filter free of the clip, disconnect the top tubing from the fitting. Install the new filter, noting the proper
orientation (shown below).
4
Repeat for the lower tubing. Dispose of the used filter.
5
Install the filter in the opposite manner to removal. Start with the filter at an angle, with the lower part pressed
into the clip. Guide the tubing through the rear plate as needed to ensure the tubing isn’t kinked. Rotate the
filter inward and upward into the clip. As the top of the filter enters the clip it will be strongly pulled in.
6
Double check the tubing, ensuring it is fully seated on the elbow fittings and is not kinked or pinched.
