push upward on the grey retaining ring on the filter housing outlet fitting. This will allow for the ¼

drain tube to be removed from the fitting.
Step 2:
Once the ¼
”
clear drain tube has been disconnected, the filter housing bowl may be unscrewed from the
top portion of the filter housing which is connected to the internal system piping.

Once the filter housing bowl has been unscrewed, the filter cartridge inside is removed by first
unscrewing the black retaining disc at the base of the cartridge and then pulling down on the cartridge.

the filter housing. Screw the black retaining disc back onto the central metal threaded rod.
