UPDATE spined 2.0.
Updating spined 2.0.
Update Capacity consists of a new lid, a new O-ring and a bushing for the plug of 6 mm so you avoid dropping it when using mate 1.0 uno / duo.
1. Open the knob on max. The spring should thus be at the top of the glass.
2. Use a small plate chisel and unscrew the knob in the side. The screw is very small so keep track of it.
3. Release 4 screws on the lid, use pH starters.
4. Take loose O-ring and plastic tubes from the lid.
5. Install the new O-ring on the plastic tube.
6. Replace the lid against the new one.
7. Re-install the parts.
Note: Be careful when the lid is tightened with the 4 screws. Do not overdo these, it will tighten at normal force.
