Inspection & Preparation
I. Installation Safety Guide
- AWS 7500 works on standard 100-240 V AC supply power plug only.
- Control valve should be higher than drain outlet, and not far from the drain hose. If the drain valve is squeezed or higher than control valve, then the brine solution will not be sucked from the brine tank due to pressure difference.
- When the process is changing from fast rinse (4) to filling cycle (5), there may be chances of high pressure in which the water will flow through the drain pipe.
- Placement of the vessels should be as depicted in the diagram (INCORRECT vs. CORRECT). The INCORRECT placement shows the vessel lying on its side, while the CORRECT placement shows it standing upright.
- Handle with care when moving the water softening system. Do not turn upside down, drop, drag, or set on areas with sharp protrusions.
Device Location (Fig-A)
A diagram (Fig-A) shows the water softener unit with inlet, outlet, regeneration, and drain connections. The Multi-Port Valve (MPV) is visible at the top.
- Water softener should be located close to the drains.
- Ensure the unit is installed with enough space for operating and maintenance.
- Brine tank needs to be placed close to softener.
- The unit should be kept away from the heater, and not to be exposed outdoor. Sunshine or rain will cause system damage.
- Avoid installing the system on an acidic/alkaline, magnetic, or strong vibration platform, as these factors can cause system disorder.
1. Install Control Valve (Fig-B)
A diagram (Fig-B) shows the control valve assembly with its components: Control Valve, Base O-ring, Riser Pipe, Top Strainer, Resin Tank, Riser Pipe, and Bottom Strainer.
- Glue the riser pipe to the bottom strainer with UPVC glue and put it into the vessel tank.
- Ensure that the 'O' ring inside the control valve doesn't fall or get misplaced while fitting onto the vessel.
- Fill Geolex media followed by water softener resin media into the vessel. Plug the top of the riser pipe to prevent media entering the pipe.
- Fix the top strainer into the Multi-port valve.
- Insert the riser tube into the control valve.
2. Install Animated Connector (Fig-C)
A diagram (Fig-C) shows an animated connector with inlet, sealing ring, outlet, flow meter, and probe wire. The instruction is to put the sealing ring into the nut of the animated connector and screw it into the water inlet.
3. Install Flow Meter (Fig-C)
Following the diagram (Fig-C), put the sealing ring into the nut of the flow meter, screw it into the water outlet, and insert the probe wire into the flow meter.
4. Install Drain Pipeline (Fig-D)
A diagram (Fig-D) shows a connector, sewer, and drain hose. Slide the drain hose connector into the drain outlet and locate the drain hose well as shown in the figure.
5. Connect Brine Tube (Fig-E)
A diagram (Fig-E) shows a tube bushing, hexagonal nut, brine tube, brine line connector, and a "No Leakage" indicator. Slide the 3/8" brine tube hose connector over the end of the brine tube. Insert the tube bushing into the end of the brine tube. Tighten the nut onto the brine line connector and connect the other end of the brine tube with the brine tank with the help of a strainer.
Note:
- MPV valve should be higher than the drain outlet, and not far from the drain hose. If the drain outlet is higher than the control valve, a check valve must be installed in the drain outlet. Otherwise, wastewater will flow backwards into the water outlet when brine is refilled.

Interconnecting Cable
Diagrams show two interlock cables (Interlock Cable 1, Interlock Cable 2) connected to circuit boards with displays. Instructions are provided for connecting these cables.
- The interlock connector needs to be connected with the same color of the interlock connector on the main board.
- Use interlock cable to connect the Black socket of one valve with the Blue socket of another valve in the series.
