Routine Maintenance
Label the machine with appropriate warning signs such as "Do Not Use / Contains
Formaldehyde" to prevent use of the RO until it is properly rinsed.
4.4.1.1 Formaldehyde Pre-Disinfection Procedure
1.
Turn the Millenium™ RO off.
2.
Disconnect the RO system from the dialysis machine.
3.
Connect the RO product rinse line to the product port and place the open end in a
drain.
4.
Connect the waste line to the RO and run the other end to a drain.
NOTE:
Follow your facility’s procedure for formaldehyde disposal. The drain line may
have to be placed in a container. Verify that the operate/flush valve is in the
OPERATE position.
5.
Prepare a 4% solution of formaldehyde (800 ml of 37% formaldehyde to 2 gallons
of pre-treated water. The 2 gallons of solution is adequate for the Millenium™
RO).
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 4.2%. Consult the Medical Director or Director of Nursing to
determine the correct solution strength. Osmonics will not be responsible for any
damaged components due to incorrect solution strength.
6.
Attach the quick-disconnect end of the disinfect line to the disinfect port of the
RO. Place the open end of the disinfect line in the disinfectant.
4.4.1.2 Formaldehyde Disinfection and Dwell Time
1.
Push and hold the disinfect switch to operate the RO pump. Allow the RO to
operate until the disinfectant has been drawn into the machine.
CAUTION:
Check that there is waste flow within 10 seconds. If not, push the switch once and
verify that the disinfect line is submerged in the solution and the QD is connected
correctly. Do not allow air to be drawn into the RO system, as this will damage the
pump.
2.
Test for the presence of formaldehyde in the product line (the RO must be
running).
3.
Release the disinfect switch.
