R.O. DRINKING WATER SYSTEM

FIVE/ONE YEAR LIMITED WARRANTY

What Does This Warranty Cover?

This warranty covers any defects in materials and workmanship of the Marlo R.O. Drinking Water System
when installed and operated within recommended parameters, with the exceptions stated below.

How Long Does The Coverage Last?

Marlo will warrant its R.O. Drinking Water System (except for the reverse osmosis membrane), for a period of
five years from the date of purchase. The reverse osmosis membrane is warranted for one year from date of
purchase. All implied warranties including merchantability and fitness for a particular purpose are limited to
five years from the date of purchase for the R.O. Drinking Water System, except for the reverse osmosis
membrane which is limited to one year from date of purchase. Some states do not allow limitations on how
long an implied warranty lasts, so the above limitations may not apply to you.

What Will Marlo Do?

Marlo will repair or replace at its discretion any defective component. You must pay any labor charges. You
must also pay for shipping or travel charges to return the defective part(s).

What Does This Warranty Not Cover?

This warranty does not cover the disposable sediment and carbon filters whose service life depends on feed
water conditions. In addition, the membrane is only warranted if the required feed water conditions are met. 

The above warranty will also not apply to any part of the Marlo R.O. Drinking Water System that is damaged
because of neglect, misuse, alterations, accident, misapplication, physical damage, or damage caused by fire,
acts of God, freezing or hot waters or similar causes. Consequential and incidental damages are not recover-
able under this warranty. Some states do not allow the exclusion or limitation of incidental or consequential
damages, so the above limitation or exclusion may not apply to you.

We recommend that you use only  authorized Marlo replacement parts since improper parts or incorrectly per-
formed maintenance or repair voids this warranty. In addition, if non Marlo parts are used, contaminant reduc-
tion claims, and certifications to/from ANSI/NSF Standard 58, WQA Standard S-300, and/or state approvals
are no longer valid.

How Do You Get Service?

In order to be eligible for service under this warranty you must (a) contact your local dealer who supplied the
unit or (b) contact the factory for the dealer nearest you.

How Does State Law Apply?

This warranty gives you specific legal rights and you may also have other rights which vary from state to
state.
