The following steps should be followed to change the cartridges.
Cartridge Replacement
Cartridge replacement is made easy with the Watts Kwik Change system. The cartridge heads contain
built in check valves and shutoff valves so that the cartridges can be changed without shutting off the
water supply or the storage tank. The head are also hinged to allow easy access to the cartridges.
Note: A small amount of water may be released when changing cartridges.
NOTE:
This reverse osmosis system contains replaceable components critical to the effi ciency of
the system. Replacement of the reverse osmosis component should be with one of identical
specifi cations, as defi ned by the manufacturer, to assure the same effi ciency and contaminant
reduction performance. Periodic inspection and following proper system maintenance is critical
for continued performance.
