System Maintenance
Notice:
Unplug the Pump & UV before perorming any maintenance to the system.
Notice:
If your RO system is connected to an icemaker or other equipment, you must turn off
the connection to the equipment before performing any maintenance.
Membrane Replacement Instructions
The membrane should be replaced every 1-2 years, depending on the water quality.
Before starting, shut off the cold water supply to the unit and unplug the UV system. Lift the handle on the
faucet to drain out the storage tank completely and allow the system to stand for 10 minutes in order to fully
decompress the tank. Leave the faucet open until the membrane change is complete.
1. Unscrew the fitting to the cap of the membrane housing. Use the membrane wrench if the cap is too tight.
2. Using pliers, pull out the old membrane from the housing.
3. Remove the new membrane from its bag.
4. Insert the membrane in the housing in the same direction as the old membrane.
5. Push the membrane firmly into the housing until it seats on the far end.
6. Screw the housing cap back on, making sure the o-ring is positioned correctly.
7. Screw the fitting (with tubing) back onto the housing.
8. The system is ready. Turn on the water supply. Check for any leaks.
9. Drain the first two tanks of water before drinking.
Filter Replacement Instructions
All pre and post-filters should be replaced every 3-6 months.
Before starting, shut off cold water supply to unit and unplug the UV system. Lift the handle on the faucet to
drain out the storage tank completely and allow the system to stand for 10 minutes in order to fully decompress
the tank, reserving some of the RO water to use to rinse the filter housings. Leave the faucet open until the
filter change is complete.
1. Remove pre-filters from filter housings. Use a filter wrench if the housings are too tight.
2. Discard used filters, but save o-rings for re-use.
3. Clean inside of all housings with a mild soap solution, and then rinse with RO water.
4. Lubricate the o-ring and replace in filter housing.
5. Insert the new filters into the appropriate housings and replace the housings onto the system.
6. Disconnect the post-filter by removing the fittings on either end. Replace with new post-filter and re-use
the existing fittings.
(Feed end tee is connected by a short length of tubing, remove this and use to connect to new filter.)
7. Follow the normal Start-up Procedures. (Drain the first tank of water after changing the filters before
drinking.)
Ultraviolet (UV) System Maintenance
Warning!
Always disconnect power before performing any work on the disinfection system.
Always shut-off water flow and release water pressure before servicing.
Regularly inspect your disinfection system to ensure that the power indicators are on.
Replace the UV lamp annually (or biennially if seasonal home use) to ensure maximum
disinfection.
Always unplug the UV system and drain the chamber when closing a seasonal home or
leaving the unit in an area subject to freezing temperatures.
