Figure 8: Filling the DI Water Cartridge
5. Remove the John Guest fittings labeled “B” and “D” from the barbs on the top of the DI water cartridge.
To loosen a fitting, use the John Guest tool from the accessories kit to push up on the bottom ring on
the fitting, so that the ring moves toward the fitting (see Figure 9). Note that the tool is not used like a
wrench to turn the fitting, but rather is only used to press in on the bottom ring of the fitting. You may
want to rest the tool on the small post when you release the fitting, as shown in see Figure 9.
Warning
To avoid scratches, do not use a metal tool to remove the John Guest fittings on the
DI water cartridge. Always use the John guest tool provided in the Analyzer’s
accessories kit.
