Introduction

A. O. Smith Z5 RO Water Purifier uses one of the latest technologies that is used in the water purification process. A. O. Smith Z5 RO Water Purifier works under the principle
of RO (Reverse Osmosis) technology which is found to be one of the most effective processes. In this process water under pressure is passed through a semi-permeable membrane. Purified water is collected for drinking in a storage tank and impurities in the water are flushed to the drain.

Why water purification is important?
Water purification, today is essential due to the presence of harmful contaminants present in the water supply. Rapid urbanization and speedy industrial growth have led to significant pollutants and contaminants being found in the water supply. Below is a list of some of the harmful contaminants found today in the water supply which if consumed in excess can be detrimental to human health.

• TDS (Total Dissolved Solids) like Nitrates, Chlorides, Sulphates, etc.
• Pesticides and VOC (Volatile Organic Compounds).
• Heavy metals like Mercury, Arsenic, Lead, Chromium, Cadmium, etc., imbalanced pH.
• Microorganisms such as pathogenic bacteria, viruses, protozoa, and cysts.

A. O. Smith Z5 RO Water Purifier removes excessive TDS (Total Dissolved Solids) in water by more than 95%. A. O. Smith Z5 RO Water Purifier reduces heavy metals, removes pathogens, and balances the pH value. By this, it ensures you safe and great-tasting water.

How does the A. O. Smith Z5 RO Water Purifier work?
A. O. Smith Z5 RO Water Purifier has 8 stages of the purification system, wherein the water is passed through the various stages and progressively filtered to get purified water which is stored in the in-built storage tank.
Stage 1 – Pre-filter
The Pre-filter is used to remove physical contaminants such as dirt, dust, soil particles, and turbidity present in the water. This improves the life of the Sediment filter.
Stage 2 – Sediment filter
The Sediment filter is used to remove fine and coarse physical contaminants present in the water. This improves the life of the ART™ MAX.
Stage 3 – ART™
MAX (Advance Recovery Technology™) The ART™ MAX (Advance Recovery Technology™) is scale control media that conditions the water to reduce scaling potential in the water.
Stage 4 – SCB filter®
The SCB filter® uses carbon block which reduces harmful chemicals including pesticides, volatile organic compounds, residual chlorine, etc. It also adsorbs bad taste and odor-causing organic compounds from water.
Stage 5 – RO (Reverse Osmosis) membrane
RO membrane contains a semi-permeable membrane wherein the water is passed through the semi-permeable membrane to remove TDS (Total Dissolved Solids) and heavy metals like mercury, arsenic, lead, chromium, and cadmium etc. It also removes micro-organisms like bacteria, viruses, protozoa, and cysts.

Stage 6 – Alkaline Min-Tech
This is an advanced filter with a balanced source of essential minerals like Calcium and Magnesium which helps to keep our body healthy. It enhances the taste and maintains the sweetness of the water. The advanced pH balancing technology will maintain the pH of the water as per standards. The odor control will give the optimum protection to the pure water and make water free from trace odor and increase the taste.
**Stage 7 and Stage 8 – ZX Double Protection Dual filter®**
This is a dual filter where water is passed through the Post Carbon block which acts as a polisher and enhances the taste of water. In the final stage, water is passed through SCMT (Silver Charged Membrane Technology) filter ensures double purification of water making it Safe and Healthy for drinking. Patent Applied

Note: The Ball valve comes along with the product as a standard accessory.

Function of indicators

Power ON indicator ON
This indicates, that the system is switched ON/OFF conditions.
Tank full indicator FULL
This indicates that the Water Purifier tank is full.
Auto flush indicator FLUSH
This indicates flushing is in progress. Every time the water purification process is activated the auto flushing mechanism cleans the RO membrane. It enhances the life of the RO membrane.
Filter change indicator FILTER
This indicates that the RO membrane and filters need to be replaced.

• The filter change indicator starts blinking indicating that the RO membrane and filter life is reaching its end time.
• When RO membrane and filter life reaches its end, the Filter change indicator keeps on blinking and the unit stops functioning. The unit stops functioning, approximately 1 month after it starts blinking.

Safety Precautions

Electrical Safety
Even though these products are designed keeping the highest safety standards in mind, there are certain Do and Don’t that need to be followed while using these products.

Figure 5 Power plug must be used with a 230 V outlet. It is recommended to connect the product to the power supply only with the plug that is provided with the purifier. Do not pull out or touch power plug with wet hands to avoid electrical shock.
Figure 6 Product should be installed only by A. O. Smith Company Authorised Service Technician. Do not open the purifier for cleaning the filters or for any part replacements. This must be done only by A. O. Smith Company Authorised Service Technician.

Figure 7 Make sure that the feed water is tested before installation. Do not install the product if the TDS and Hardness are more than that prescribed in the recommended feed water conditions (Refer page 14).
Figure 8 Install the product away from direct sunlight.

How to use

1. Turn ON the water connection through the ball valve. Figure 9

2. Switch ON the power supply. Figure 10
   

3. To dispense water continuously, lift up the water faucet lever for continuous water flow. Figure 11
   Note: Water is dispensed continuously only by lifting the faucet lever upwards.

4. To stop the water flow, pull down the water faucet lever to position 2 slowly and then to the initial position. This avoids the splashing of water. Figure 12

NOTICE

• Discard the first cycle of pure water, before you start using it for consumption.
• Make sure to discard the water in the storage tank if you have not used the purifier for more than 2 days.
