should consult GE Osmonics' Engineering Department as to the suitability of the
solution to be run in the membrane elements.
Limitations on pH and temperature can vary with membrane type and the
application of the equipment. For general water treatment, pH should be kept
between 3.0 and 7.0 with a temperature below 85ºF (29ºC) unless specifically
designed for higher temperatures. For special applications or for pH or temperature
ranges outside the stated limits, GE Osmonics may reduce the warranty period.
A membrane element which fails to perform satisfactorily within the first 90 days
after receipt, has not been mishandled, and is returned to the factory, will be replaced
free of charge except for freight and local labor. If a membrane element fails to
perform satisfactorily during the balance of the warranty period and with the return
of the membrane element to the factory, GE Osmonics will replace the membrane
element with a new membrane element and will charge the User for the portion of
the 12 months that the membrane element was used plus incoming freight and local
labor. Such pro rated charges will be based on the list price prevailing at the time of
warranty consideration. A new membrane element supplied under warranty terms
will carry the standard 12-month new membrane element warranty. If membrane
elements have not been placed in use at the end of the permissible storage period,
the date of first use shall be considered to start the end of the permissible storage
period.
The customer shall be responsible for acceptance testing for the membrane elements
received to ensure that they meet the published performance specifications. GE
Osmonics shall be notified within thirty (30) days for first use of any membrane
element not meeting specifications. Should GE Osmonics not receive notification of
non-compliance with performance specifications within said thirty (30) day period, GE
Osmonics will consider that all membrane elements are accepted.
All membrane elements being returned for non-warranty issues or credit for unused
membrane elements must be returned unused in their original packing. Membrane
elements returned not conforming to said criteria will be subject to rejection or added
fees to restore membrane elements to sellable condition.
GE Osmonics warrants storage of membrane elements as follows:
1. All dry membrane elements (excluding cellulosic elements) for six (6) months at
ambient temperatures less than 100ºF.
2. At temperatures between 100ºF (38ºC) and 122ºF (50ºC) for three (3) months,
provided elements are stored in the original box with the polyethylene bag
intact under dry conditions.
3. At temperatures over 122ºF (50ºC) there is no warranty.
4. All wet membrane elements for a period of three (3) months or expiration date
whichever occurs first when shipped from any GE Osmonics manufacturing
facility to a location in Canada, the United States, Mexico or Puerto Rico; or for
