Avoid exposure to direct sunlight
and installation in damp areas.
Do not place the reject
water pipe at a level
higher than the purifier,
else reject water may flow
backwards into the purifier.
Avoid sharp bends in pipe.
Do not block the reject water pipe.
Use Genuine OASIS Spare Parts
for optimum performance
Do not try to service the purifier on
your own. Instead, call the service
technician for help.
Do not confine
the purifier in a cabinet
Make sure that the
purifier is connected to normal
temperature water supply only.
Maximum distance between the
purifier and water source should
not be more than 3 meters.

Reverse Osmosis also known as Hyper Filtration, is the finest filtration process known till date. The
process ensures removal of particles as small as ions from a solution. Reverse Osmosis process
uses a semi-permeable membrane to reduce the dissolved salts from potable / brackish water.
In Reverse Osmosis, water pressure is applied on the inlet impure water resulting into the
squeezing of pure water from the concentrated end of membrane towards the diluted end.
Dissolved salts present in water as charged ions get repelled by the RO membrane and are not
allowed to pass through. Similarly, bacteria and germs are also blocked by the ultra-fine pores of
RO membrane. These rejected impurities suspended on the concentrated end of the membrane
are washed away in a stream of waste water preventing the membrane from clogging.

OASIS 50 LPH-New is designed to facilitate wall mounting as well as counter-top purification.
It is easy and convenient to install.
Recommended Site Preparations:
• Single phase 100-250 V AC, 50-60 Hz. supply not more than 3m away from the point of
installation
• Raw water supply with ½ inch nipple not more than 3m away
• Drain for reject water not more than 3m away
• Installation space as per the dimensions of the purifier
• For proper installation, make sure that the purifier is mounted on a wall surface. Avoid
installation on wooden and metallic stands
• For optimum inlet pressure, source water tank should be at least 10 ft. above the purifier
installed

Installation
Instructions

1. Screw in two 10x50 self taping screws.
2. Wall-mount the purifier with the help of slot holes given on backside.
3. Fasten the SS ball valve to ¼ inch port of 3-way connector.
4. Attach the threaded end of 3-way connector to raw water supply
and plug off the other end or connect to a tap.
5. Now connect one end of white pipe to SS ball valve and the
other end to lower elbow fitting connector labeled as WATER IN,
on the Left side of purifier
6. Connect one end of blue pipe to upper elbow fitting connector in REJECT WATER FR
and lead the other end to drain.
7. Connect the purified water pipe to the water cooler.
8. Turn on the lever given on SS ball valve to initiate the water flow to purifier.
9. Allow the filters to pre-soak in the water for 2-3 minutes.
10. Connect the power supply.
11. Installation is complete.

• Switch on the power supply
• Allow water to fill to the maximum level
• Switch off the power supply
• Open the faucet and drain water to remove residual dust particles present in
the pipes and tank
• Close the faucet and switch on the
power supply
• Purifier is ready to use
• If the supply cord is damaged, it must be replaced by the original part in order to avoid hazard
• Children should be supervised to ensure that they do not play with the appliance
• This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety
• Read the maintenance instructions before opening the appliance
• The appliance must be disconnected from the supply before replacing the filters.
To ensure that the purifier operates at its BEST, a routine maintenance must be performed. The
frequency of the maintenance will greatly depend upon the raw water quality and consumption
of purified water.
• Tank must be drained and cleaned once in every 15 days
• Replace RO membranes once in a year
• Replace sediment filter, activated carbon filter once in a year or earlier if they get clogged.
It is recommended to change FRT along with the filters
Although the rejected water has high concentration of salts, it is absolutely clean and free from
impurities like chlorine, dirt, sand, etc. This rejected water usually goes down the drain but can be
used for gardening purpose. The high concentration of salts and minerals accelerate the plant
growth. Rejected water can also be used for cleaning utensils, mopping etc.

Important Safety Instructions
Warning
Please note that the replacement time of consumables such as filters and membranes is
dependent on the quality of raw water and the quantity of water consumed.

For optimum performance we recommend the following frequency
for replacement of cartridges:
Sediment /Activated Carbon : Once in a year or earlier if they get clogged
RO Membranes : Once in a year or earlier if they get clogged
*Purification capacity tested on raw water with TDS level of 750 ppm at room temperature.
