Salient Features
Presenting the all-new KENT Tap Guard, which will provide your family with safe, clean and germ-free water. Now
just connect the innovative KENT Tap Guard to your tap and get instant, convenient and unlimited supply of
quality water suitable for brushing teeth, gargling, washing fruits/vegetables and cooking.
At the heart of KENT Tap Guard is the granular activated carbon and state-of-the-art Hollow Fiber UF Membrane.
While granular activated carbon eliminates the chlorine, odour and turbidity, the UF membrane effortlessly
removes bacteria & cysts along with suspended impurities to generate water much superior to the boiled water.

Tips for proper use
 If the unit is used every day, run water through the filter cartridge for 10 seconds before use to clean the outlet.
 If the unit has not been used for 2 days or more, run water through the filter cartridge for 60 seconds before use.
 If the unit has not been used for 2 weeks or more, we recommend replacing the filter cartridge before reuse as
it may have lost its effectiveness.
 Keep the purified water outlet clean.
 The filter cartridges must be replaced every 6 months. Its life span depends on consumed water volume, quality
and pressure.

If water leaks from the faucet attachment, the valve body or the spout may be damaged. Please take care when
removing the water purifier to avoid injury from the damaged part. (Refer Pg. 21 for “Basic Troubleshooting”.)
 Do not use soap, chemical detergents, thinner or alcohol to clean the unit.
 Do not use the purifier without a cartridge.
 Do not remove the cartridge during filtration.
 Do not run water of over 35°C through the filter cartridge.
 Do not run water of over 50°C through the unit under any condition.
 Do not block or attach other objects to the filtered water outlet.
 Do not allow water to freeze in the unit.
 Do not use the unit near objects which generate heat.
 In areas with high water pressure, open the faucet slightly while using the unit.

Preventing injury

 The unit cannot change hard water to soft water or soft water to hard water.
 In the event of extremely murky water, turn the water selection lever to “Unfiltered Spray” and run water until it
becomes clear before filtration.
 If attached to a faucet used for both hot and cold water, users should ensure that hot water above 35°C does
not enter the cartridge.
This may result in death of your fish in the event that dechlorination performance is lowered.
Do not use the filtered water in fish bowls or aquariums
Other precautions
Do not connect the unit to instantaneous water heaters. This could result in damage to the water heater.
Preventing damage to other appliances
 If the faucet is not tight enough, excessive load may cause water to leak from the faucet attachment, faucet or
the plumbing system.
 If the end of spout is covered with a plastic insulation cap, water may leak from the faucet attachment or
damage the cap due to excessive load.
[Note: Please remember that the damage to spout / the spout cap and leaks if any caused by the damage are
not covered under Warranty.
]
Avoid damage to the faucet and its parts
Change the cartridge if flow rate decreases dramatically due to Hollow Fiber UF Membrane blockage and does not
improve even after backwash. (Continued use of a blocked cartridge in areas with high water pressure can result
in cartridge breakage.)

Attaching/replacing the filter cartridge.
When removing the filter cartridge, follow the instructions in reverse order from step 3.
Don’t forget to turn off your faucet and set the water selection lever to “Unfiltered Straight”
before removing the filter cartridge.
Remove the cartridge
cap by turning it in the
direction of the arrow.
Push in the membrane
cartridge so that the line on
the catridge is at the V-shaped
notch on the purifier.
Turn the catridge cap
in the direction of the
arrow until stops.

Immediately after filter cartridge replacement, run a slow stream of water through the filter cartridge for 30
seconds before using. Not doing so will cause air to become trapped inside the filter cartridge and
reduce water flow.

Pure Water (Purified water).
The flow rate of filtered water is slower than
that of unfiltered water.
Use for brushing teeth, gargling, washing
fruits and vegetables and cooking.
Use for washing dishes or
other times when a lower flow
rate is preferred.
Use for a high flow rate.

When to replace the Filter Cartridge
You should change the filter cartridge in case of the below given events.
1. Recommended replacement period.
The filter’s dechlorination capacity is 1500 litres. For a family of 3-4 who use 8L of filtered water per day for
brushing teeth, gargling or washing fruits and vegetables 1500 litres translates into a filter cartridge service
life of 6 months. This life may be enhanced by backwashing the filter cartridge.
It is recommended to change the filter cartridge every 6 months or earlier.
2. Chlorine odour remains after filtration.
The filter cartridge is losing its ability to remove chlorine effectively. Granular activated carbon can remove
residual chlorine. When the removal capability is reduced below a certain level, the filtered water may smell
of chlorine.
In areas with high levels of residual chlorine content and / or high water pressure and therefore, a
high flow rate open the faucet only slightly to restrict water flow.
3. Conspicuous decrease in flow rate.
The Hollow Fiber UF Membrane contains billions of micro-pores small enough to remove impurities in
units of 0.1 micrometers in diameter. Membranes are arranged in a multilayer configuration for optimal
efficiency in filtering out micro-contaminants, red rust, coli and other bacteria and cysts. These
micro-pores gradually become clogged during use due to accumulations of rust and turbidity, resulting
in a drop in the flow rate from the filtered water outlet.

The Filter Cartridge should be cleaned at least once in 15 days.

faucet attachment.

Basic troubleshooting
1. Remove the cartridge cap by turning it in the
anticlockwise direction.
2. Remove the filter cartridge.
3. Fill the 20ml syringe with pure water.
4. Fit the syringe into the hole provided in the
centre of cartridge and slowly inject water from
syringe into the cartridge. Dirty water if any,
flows out of the side hole provided on cartridge.
5. Repeat operation if required.
Backwashing the filter cartridge
17
1. Remove tap purifier from the faucet in
reverse order of installation.
2. Rinse the purifier with unfiltered tap water.
Do not use detergent, thinner or alcohol
to clean the surface.
3. Use a clean toothbrush to clean the
filtered water outlet and rinse off any
contamination under running tap water
and wipe well with a clean cloth.
4. Rinse the stainless steel screen and the
unfiltered water outlet using a clean
toothbrush.
5. Backwash the Filter Cartridge regularly
(Refer Backwashing the Filter Cartridge).
