IMPORTANT: Before installing this reverse osmosis system,
make certain your water supply complies with the following
operating specifications. Failure to do so may reduce the
effectiveness of the system and will void the warranty.

If the hardness of your water is above 10 gpg (171 mg/L), lime
†
scale will build up rapidly on the membrane. Scale buildup will
plug the membrane and make the system ineffective. We do not
recommend these reverse osmosis systems to be used with
water in excess of 10 gpg (171 mg/L) hardness.
A maximum total level of approximately 0.01 ppm sulfide, iron
‡
or manganese is permissible. See your local dealer to reduce
these substances in your water.
