Installation of RO Water Purifiers

The installation process begins with site preparation. The recommended site preparation steps are shown in the following figure:

• Ensure single phase connection is within 3m of the point of installation 
• Ensure raw water supply is within 3m
• Ensure raw water supply tank is at least 10 feet above the purifier 
• Ensure there is a sink near the purifier
• Ensure waste water drain is within 3m
• Ensure enough space is there as per the dimensions of the purifier 

Installation Procedure 

The following steps should be performed when installing a wall mounted RO water purifier:

1. Disconnect the water supply line from the normal tap water. 
2. Mark screw locations at same horizontal level on the wall. 
3. Screw in two self -taping screws into the marked positions. 
4. Hang the purifier with the help of wall mounting screws present at the back of the purifier. 
5. Fix the SS ball valve to the port of 3-way connector. 
6. Connect the raw water supply to the 3-way connector:                                       a. Connect the threaded end of the connector to the raw water supply.        b.  Connect the other end to a tap, if     required. 
7. The left side of the purifier has a lower pushfit elbow fitting labeled as WAYER IN. 
8. Take the white pipe which is for raw water supply:                                               a. Connect one end to the a SS ball     valve.                                                           b.  Connect the other end to the   WAYER IN fitting. 
9. The left side of the purifier has an upper pushfit elbow fitting labeled as REJECT WATER 
10. Take the blue pipe which is for reject water.                                                           a.  Connect one end to the REJECT   WATER fitting.                                           b. Leave the other end in the drain. 
11. Open the ssball to start the flow of water into the purifier. 
12. Ensure that the filters are soaked in water before connection the power supply.     

Pre-installation Process of Water Purifiers

Before beginning the installation, the pre-installation process should be followed to ensure that the unit is properly installed. The pre-installation checks of tasks as shown in the following figure :

Inspection 

Inspect the carton and the unit to ensure there are no concealed damages due to rough handling 

Removing the package 

Remove the components from the shipping carton carefully 

Package validation 

Check that all installation parts such as the unit, faucet, tubing and installation hardware are present 

The following figure lists the guidelines that should be followed before installing an RO water purifier:

Avoid exposure to direct sunlight or heating devices 

Avoid placing the rejected water pipe at a higher level than the purifier 

Avoid sharp bends in the pipe 

Avoid bending or blocking the rejected water pipe 

Ensure that the puriifer is connected to the normal water supply only 

Ensure that the purifier is installed within 3 meters of the water source 

Avoid confining the purifier in a cabinet

Functioning of RO Water Purifier

The following figure explains the steps involved in the functioning of an RO water purifier:

Step 1 Water enter from the supply line 
Step 2 Water enters the sediment filter which strains out sand, dirt and sediments 
Step 3 Water enters the carbon filter which removes chlorine and other contaminants
Step 4 Water enters the RO membrane which filters out all additional contaminants 
Step 5 Water enters the storage tank
            Waste water containing impurities is drained out 
Step 6 Water enters post filter to remove any remaining odor and taste in water 
Step 7 Water leaves the filter and goes to faucet

Component of RO Water Purifier

The following figure lists the basic components of an RO system:

Supply line valve  Attaches the inlet                                      of the RO pre'filter                                    to the water source                                   through a tube 

Pre-filter sediment Removes sand,                                           dirt and other                                            sediments 

Carbon filter  Address chemical                                      impurities such as                                   chlorine and pesticides                           and improves odor and.                           taste of water 

RO membrane  Removes almost all                                   dissolved salts,                                           impurities and                                           bacteria 

Water tank  Stores water before 'post                         filtration'

Post filter  Also known as 'polishing'                         filter as it removes the                             remaining taste and odor                       from the treated water 

Shut-off valve  Automatically shuts-                                 off the water supply                                  to the membrane                                      when the storage tank                             gets full 

Check valve  Prevents backward flow.                          of water from the tank.                           to the membrane  

Flow restrictor  Maintains pressure                                  on the inlet of the                                      membrane to ensure                                the highest quality of                                water 

Drain  Connects one outlet of the                      membrane to the drain to                        dispose off waste water 

Properties of RO Water Purifier

The properties of an RO water purifiers are shown in the following figure :

Simple operation and control 

RO Water Purifier

RO water purifiers work on the principle of Reverse Osmosis (RO). In this process, pressure is applied on contaminated water to force it through a semi-permeable membrane. The water is purified by filtering and flushing out the impurities as shown in the following image :
