Disinfection
When cartridge activation and recovery adjustments are complete, the storage tank and associated piping must be disinfected, then completely flushed. The steps for this are outlined below.
1.Locate the 3/8" OD tubing that connects to the inlet (left side) of the storage tank. Disconnect the end which connects to the elbow fitting at the processor. Measure 1 ounce of 5.25% bleach for every 7.5 gallons of storage tank capacity. Pour this volume of bleach into the tube that leads to the storage tank.
2.Once sufficient water has entered the storage tank (more than 1/4 full), demand treated water from at least one piece of equipment the
3.Allow the storage tank to fill until the booster pump turns off. Allow the chlorinated water to remain in the storage tank and distribution piping for 10 minutes.
4.Unplug the power cord. Drain the storage tank by demanding water downstream and allow the storage tank to drain. Once the storage tank is empty, stop demanding water downstream.
5.Apply power to the system by plugging the power cord into the receptacle. Once sufficient water has entered the storage tank (more than 1/4 full), demand treated water from at least one piece of equipment the
6.Allow the storage tank to fill until the booster pumps turns off.

2.The system inlet and outlet valves must be open, the sample outlet and flushing valves must be closed and the drain line must be unrestricted.
DUAL OUTLET AND BLEND ADJUSTMENT
The
•The outlet marked “STEAMER” provides water directly from the RO Membrane. The TDS of this water is very low, ideally suited for applications such as flash steamers and other equipment that “boils away” the water. This outlet requires no adjustment.
•The outlet marked “COFFEE” can produce a wide range of water qualities. It combines or “blends” two sources of water; 1) directly from the RO Membrane and, 2) filtered water containing the same level on mineral content as the raw (feed) water. The following text describes the adjustment of this feature.
1.Open the feedwater blend valve (FBV) and dilution blend valve (DBV) fully. See Figure 6 for location of these valves.
2.Demand flow on the “COFFEE” line. The flowrate should equal the maximum expected demand of all connected equipment.
3.Access the “Coffee TDS” view screen on the controller to observe a
4.Compare TDS value on controller to application requirement. If controller reading is higher than requirement, slowly close FBV until TDS value is met. If controller reading is lower than requirement, slowly close DBV until TDS value is met.
