3. Turn off the RO; do not operate the RO dry.
CAUTION:
Do not allow air to be drawn up into the RO unit as this will damage the pump.
4. Disconnect the drain line from the tank and re-attach the drain line extension.
SECURE the drain line extension in the drain. Make sure the RED QD
connector is fully joined and latched (listen for the 'click').
5. CLOSE the 'Product Valve'. Disconnect the product line from the tank, and
attach the product rinse line extension' to the product line. The Product Valve
should remain closed at this time.
WARNING:
Make sure the drain line is secured in the drain. Disinfectant will be flowing out
of the drain line during this step. Turn the RO unit power switch ON and observe
the disinfectant level in the tank. It will begin to empty to drain. Turn the power
switch OFF when the disinfectant tank is almost empty.
CAUTION:
Do not allow air to be drawn up into the RO unit as this will damage the pump.
6. Disconnect the feed water line (green QD) from the disinfect tank, and
disconnect the RO drain line extension (red QD). This closes the internal valves
in the QD connectors, sealing the lines to prevent leakage of disinfectant.
7. Allow the RO to soak in the disinfecting solution for 36 minutes -12 hrs.
Thirty-six minutes contact time is expected to result in 90% bacteria kill; 12
hours is expected to kill 99% of the bacteria. The minimum amount of soak to
achieve disinfection is better for the membranes.
CAUTION:
Renalin may not be left in contact with RO membrane for longer than 12 hours
or damage to the RO membrane will occur. Do not store the unit in an overly
warm room such as a utility room with a water heater, or boiler room during
dwell time.
8. Ensure that "Do Not Use / Contains Disinfectant" signs are displayed in
appropriate places.
CAUTION:
The RO system is now filled with the disinfectant solution. THE USER MUST
ENSURE THAT THE MACHINE IS NOT USED to provide water for any
purpose whatsoever until the unit has been thoroughly rinsed and tested to verify
absence of residual disinfectant in the product water stream.
