F-801 Internal RO System by GE Osmonics
12552e – 27 Feb 04 4- 22 Routine Maintenance
CAUTION:
Formaldehyde or Formalin is usually provided in a clinical setting in a 37%
solution. Check the labeling on the packaging to make certain this is the case. If
the solution is other than 37%, the dilution will require adjustment. The end
solution should not exceed 2.2%. Consult the Medical Director or Director of
Nursing to determine the correct solution strength. GE Osmonics will not be
responsible for any damaged components due to incorrect solution strength.
4.4.1.2 Formaldehyde Disinfection and Dwell Time
1. Rotate the Dialyze/Flush valve to the Dialyze position. This will allow the
formaldehyde to pass from the rejection side of the membrane through to the
product side of the membrane for total system exposure to the cleaning solution
once the RO is turned on in disinfect mode (step #2).
2. Turn the F-801 RO unit ON. Let the RO operate for 5-10 minutes. Product
pressure during this step should read near zero.
CAUTION:
Check that there is waste flow within 10 seconds. If not, turn RO OFF and verify
that the disinfect line is connected properly.
CAUTION:
DO NOT ALLOW PUMP TO RUN DRY. Damage will occur if pump is run
dry.
CAUTION:
Do not allow air or foam to be drawn up into the RO unit, as this will damage the
pump.
3. Before the disinfect reservoir is emptied, collect a 10mL sample of solution
from the product rinse line to be tested for the presence of formaldehyde. This
test should indicate the presence of formaldehyde.
WARNING:
Ensure the machine is labeled with appropriate warning signs such as "Do Not
Use / Contains Formaldehyde" to prevent use of the RO until it is properly rinsed.
4. Turn off the F-801 RO and allow to dwell for 24 hours (4 hours minimum).
NOTE:
The RO may be stored for up to one year at this time. If this is the case, a 0.5%
solution may be used instead of 2%.
