Wellsys W5 Manual

Before starting the installation, any filters being used to filter the source water for the unit

must be flushed. This is important to rinse any loose carbon or debris from the filters so that it

does not plug another filter or membrane or end up inside the unit.

the unit before flushing the filters.

Whether the unit is paired with RO (Reverse Osmosis) or UF (Ultra filtration) filter

configurations, there is a basic idea that applies to both: the filters, especially the carbon filters,

must be flushed or "rinsed." This section will cover how to do this process.

Regardless of the setup used, all sediment and carbon filters must have several gallons of water

flushed through them to properly rinse the filter. The filters should be flushed in the same

direction as flow (with one exception).

1. To begin, you will need a ¼" LLDPE tube connecting the unit to a water

supply, connected at the "Water In" port on the back of the machine. Install a

¼-turn valve just before the unit to easily turn the water on and off.

2. Have a bucket, pitcher, or sink ready to catch the flush water.

3. Remove the drip tray from the unit by pulling straight out. Once removed, locate the

single screw that holds the lower front panel in place and remove it.

4. Remove the lower front panel of the unit. Press down on the top of the lower panel,

then pull away. The panel should hinge outward, and then come away from the unit

completely. Set this panel aside.

Disconnect the tube at the right side port of the precarbon filter from the elbow fitting as shown. Remove the RO filter (twist-tied to the inside of unit), the Biosure filter, and the TCR filter .

Remove and reinstall the sediment filter into the second (middle) head. Now, swap the tube connections of the supply and flush water.
