XII. Contactor Decontamination for Return to 3M
In the event that a contactor needs to be returned to 3M for analysis, it
must
be cleaned and
dried. A
Returned Material Authorization (RMA) form must be obtained
from 3M
before
a
contactor is returned. Please follow the instructions below when returning a contactor.
Call 3M at (704) 587-8888 to obtain an RMA form. Complete the form and return it by email
to your representative or fax to (704) 587-8585, Attn: Liqui-Cel

Membrane Contactor
Technical Service.
If Non-Hazardous materials (water, air, nitrogen, oxygen, and carbon dioxide) were used,
clean and dry the contactor, then place it in a clean, leak-proof plastic bag.
Write the RMA number on the outside of the shipping box.
If Hazardous Materials
were used in the contactor, follow the cleaning procedure in
section 6.0. Provide a
Material Safety Data Sheet (MSDS)
for any chemical(s) introduced
into the contactor to your product representative. Even though these chemicals need to be
flushed from the contactor prior to shipment, the MSDS is required information to safe-
guard our personnel when handling the returned contactor. Place the contactor in a clean,
leak-proof plastic bag. Write the RGA number on the outside of the shipping box.
If non-human (or other non-primate) blood or blood products were used in the
contactor, follow your established normal cleaning protocol. In addition, flush the
contactor with water until the rinsed water is completely clear. Continue rinsing for
30 more minutes to ensure the complete removal of any blood product.
Prior to returning the contactor to 3M, it must be sanitized. The following sanitizing
protocol is recommended: (5.25% available chlorine) diluted 1:500 with filtered
water (final concentration = ~100ppm available chlorine). Adjust the pH >10 using
caustic prior to adding the hypochlorite solution.
Recommended contact time and temperature with the contactor is 30 minutes at 70
F
–
100
F (21
C
– 38
C). The active chlorine level should be maintained at 100ppm during
the duration of the cleaning cycle. The entire cartridge needs to be contacted with this
solution to kill bacteria or viruses. Therefore, both the shell and tube side flow paths need
to be decontaminated.
Dry the contactor as per section IX and place the contactor in a leak-proof plastic bag.
Write the RMA number on the outside of the shipping box.
It is important to send a copy of the RMA form to 3M prior to shipping.
Fax to: (704) 587-8585, Attn: Liqui-Cel Membrane Contactor Technical Service or email
the form to your 3M representative.
