Z Series RO System by GE Osmonics
4.6 System Storage
It is not recommended that an RO unit be dormant longer than 24 hours without
disinfectant. RO units that have been left unused for more than 24 hours risk the
possibility of colonizing bacteria and exceeding acceptable limits. RO units to be stored
should first be disinfected with one of the procedures in this chapter.
CAUTION:
‘RENALIN®’ products (Renalin®, Minncare™, Peracidin™. etc.) are not acceptable
disinfectants for storage of systems. Exposure of more than 12 hours to RENALIN® will
result in irreversible damage to the membranes.
4.6.1 Formaldehyde Storage Procedure
WARNING:
Always wear rubber gloves, an apron and a facemask. If the room has ventilation, use it.
If not, wear a face respirator with an organic cartridge to remove formaldehyde fumes.
DO NOT BREATHE FUMES OR ALLOW FORMALDEHYDE TO COME IN
CONTACT WITH SKIN OR EYES. Refer to the MSDS supplied by the manufacturer of
the formaldehyde/formalin product.
WARNING:
Label machine with appropriate warning signs such as "Do Not Use / Contains
Disinfectant" to prevent use of the RO until it is properly rinsed.
1. Follow the operations/instructions for formaldehyde disinfection (Reference
Section 4.4.1) and do not rinse out after the disinfectant has been circulated in the
machine.
WARNING:
After storage, the RO unit must be completely rinsed of formaldehyde, and a bacterial
culture performed and interpreted before use (refer to Post Formaldehyde Rinse
Procedure and Product Water Culture Procedure). Perform AAMI analysis if it has been
one year or more since last done.
NOTE:
RO units can be safely stored in 4% formaldehyde for up to one year.
