Routine Maintenance
4.4.2.1 Renalin® Pre-Disinfection Preparation
CAUTION:
When ‘RENALIN®’ is to be used as a disinfectant, several preparatory steps are
required by GE Osmonics as well as the membrane manufacturer. Failure to
comply with these instructions, which incorporate instructions from the membrane
manufacturer, will jeopardize the system performance and warranty.
a.
The system must be free of all incompatible materials.
b. Clean the membranes with an acid such as 0.1% HCl or 0.4% phosphoric
acids. Calcium and Iron Cleaner may be used as an alternate. It is essential
that all iron and other transition metals be removed from the membrane
surface.
CAUTION:
The RO system must be disconnected from the tempered water source (if present).
The solution temperature must be monitored closely. At temperatures above 25
°
the ‘RENALIN®’ solution becomes very aggressive towards the RO membranes
and will damage them in a short period of time. The disinfection procedure will
raise the temperature of the solution. The operator must be prepared to add ice to
the solution or discontinue the procedure when the water temperature approaches
77ºF /25
°
C.
1.
Read and understand the ‘RENALIN®’ disinfection procedure. Pay particular
attention to steps a and b in CAUTION statement above before initiating the
procedure.
2.
Ensure the cleaning/disinfectant container is clean. Add two gallons (7.6 liters) of
RO permeate (product water) to the container.
3.
Add 2.6 ounces (80 milliliters) of disinfectant concentrate to the container and
mix to prepare a 1:100 (1%) dilution.
WARNING:
Label the machine with appropriate warning signs such as "Do Not Use/ Contains
Disinfectant” to prevent use of the RO until properly rinsed.
4.
Disconnect the dialysis machine from the RO product port and install the product
rinse line. Place the open end in the disinfectant solution container and ensure the
product valve is open.
5.
Attach the quick-disconnect end of the disinfect line to the disinfect port of the
RO. Put the open end of the disinfect line in the disinfectant.
6.
Disconnect the waste line from the drain connection and place the open end in the
disinfectant solution container.
