Ro Membrane Replacement - vitapur VRO-3 Guide D'installation, Utilisation Et D'entretien

For Model VRO-5 and VRO-5WP:
Step 1 Remove filter housings at stages 1, 2, and 3 and empty the water.
Step 2 Insert a 5 micron Sediment filter (cloth like appearance) into the 1st filter housing which is the one
on the water inlet side (white tubing) of the RO system and re-install housings.
Step 3 Insert a new 5 micron Carbon Block filter into 2nd filter bowl and re-install housings.
Step 4 Insert a new 5 micron Carbon Block filter (white end cap and plastic netting) into 3rd filter bowl
and re-install housings.
Step 5 The carbon in-line filter is located between the RO faucet and storage tank. It is attached to the RO
Membrane with brackets. The blue tubing is attached to the Carbon Post-filter. Remove it by
loosening the fitting on both ends of the post filter and replace with new filter.
Continue to Step 7.
Note: This is a good time to check the air pressure in your storage tank. For instructions please refer to
page 18.
Step 7 Perform steps 6 through 9 in the Six Month System Maintenance section for startup directions.

The membrane has a life expectancy between 18 to 36 months, depending on the incoming water conditions
and the amount the RO system is used. The reverse osmosis membrane is critical for effective reduction of
total dissolved solids (TDS). The product water should be tested periodically to verify that the system is
performing satisfactorily.
Step 1 Turn off the incoming water supply to the RO by turning the needle valve on the slip joint
connection clockwise until it stops.
Step 2 Close the valve on the holding tank.
Step 3 Open the RO Faucet and allow water to drain from the tank until it is completely empty.
Removing the Membrane:
Step 1 Remove the tube fittings from the RO membrane cap.
Step 2 Use the wrench provided to remove the cap from the housing.
Step 3 Use a pair of pliers to remove the membrane from the housing. Grip the membrane and pull firmly
on the membrane to remove from the housing and discard.
Installing the Membrane:
Step 4 Lubricate the O-rings on the new membrane with water only. Insert the end with the two black
O-rings first into the housing.
Step 5 Once the membrane has been inserted into the housing you must give a firm push to properly seat
the membrane. Replace membrane housing cap and tighten with the supplied wrench.
Step 6 The drain flow restrictor must be replaced each time you change the membrane and is located by
following the black tubing to the RO system. The flow restrictor is below the RO membrane on the
attachment bracket. It reads Flow 300. To remove, cut the tie wrap and loosen the tube connections
to it. Remove the flow restrictor and replace with a new one. Place a new tie wrap to secure to the
bracket.
Step 7 Follow the start up instructions on page 14.
