Maintenance and Servicing
The frequency with which cartridges will need to be replaced is dependent
on your feedwater characteristics, your purity requirements, and your daily
usage. Replace the cartridges when the product water purity drops below
acceptable levels of resistivity or when organic levels become too high.
Remember, used cartridges can be recycled; see P.U.R.E. information
packed with your new cartridges.
1. Turn off the EASYpure II RF and depressurize system by disconnecting
unit feedwater, opening draw-off valve and allowing water to drain
from the unit until draining ceases.
Warning Depressurize system prior to opening cartridge access door.
