9-1. Filter Element Replacement
If the filter element (FE-1) is dirty, replace it with a new one by taking the following steps.
1. Loosen the nut of the filter unit (MF-50) and pull to separate the filter unit
’s top from the inlet.
2. Replace the filter element with a new one.
3. Install the filter unit top to the inlet. Rotate and tighten the nut to secure the tube. Ensure O-ring
is correctly seated.
Tips when removing/reinstalling the entire filter
unit from/into the gas inlet:
Completely remove old sealing tape (no
residue). Wrap new sealing tape around the
threads of the filter unit (approx. 2.5 wraps).
Wrap sealing tape tautly to prevent slack.
Tape size: 13mm (width) x 100
5mm (length) x
0.1mm (thickness)
Tighten the filter unit so that movement of the
spacer is not possible. Do not over tighten the
filter unit to prevent broken inlet.
O-ring must be present.
Rotate and tighten the nut.
