Cartridge Change-out Procedure
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use Instructions before installation and use of this system.
•InstallationandUseMUST comply with all state and local plumbing codes.
•ThedisposableltercartridgeMUST be replaced every 12 months or at the rated capacity or if a noticeable
reduction in flow rate occurs.
The water filter cartridge will need to be changed every 6-12 months or when low pressure is indicated on the
manifold’s pressure gauge, whichever occurs first. Depending on local water quality, you may need to change the
cartridges prior to the recommended change-out.
1. Shut off the inlet water by rotating the inlet ball valve 1/4 turn clockwise to the “OFF” position.
2 Depressurize system.
