Sanitising Instructions for Bottled and Mains Fed Water
Industry Regulations demand that all Bottled Water Coolers
are sanitised every three months and Mains Fed Water
Coolers are sanitised every six months.
There is a fundamental difference between cleaning and
sanitising. Cleaning involves the removal of visual dirt,
sanitising destroys any bacterial contamination.
There are a number of Sanitising Systems/Solutions on the
market, but one of the simplest methods is contained in our
Sanitising Kit. The Sanitising Kit contains a buffered
Hydrogen Peroxide solution (CoolerClear Rinse and
CoolerClear Spray) which effectively destroys bacteria. It
is not harmful to humans and has little taste or smell.
To sanitise a Bottled Water Cooler:
1. Remove the bottle
2. Remove the top cover of your Bottled Cooler (two
screws at the back) to open up the
3. Pour 25 ml of CoolerClear Rinse into the water in
the tank and allow a little bit to drain
out of both front
taps (to ensure that the CoolerClear Rinse penetrates into
4. Spray all water contact areas above the water line
with CoolerClear Spray. Spray the
taps and inside the tap
nozzle with CoolerClear Spray.
5. Allow the CoolerClear to work on all surfaces for
6. Replace the top cover and Water Bottle, and flush
the tank through with fresh water
2 x to remove all residual CoolerClear. The Bottled Cooler is now sanitised.
To sanitise a Mains Fed Water Cooler:
1. Remove the top cover of your Mains Fed Cooler (two screws
at the back)
2. Remove the lid of the water tank to open up the

6. Replace water tank lid and top cover of the POU
Cooler and flush the tank
through with fresh water 2 x to remove all residual
CoolerClear. The POU Cooler is now

In the rare event that your Water Authority issues a
Boil Notice because of Cryptosporidium contamination,
proceed as follows.
If you are using our
Ceramic/Carbon Filter which comprises of a Ceramic Mantle (Doulton)
with a Carbon Block Centre, the Ceramic Mantle will block
the passage of Cryptosporidium and other cysts and you can
continue to use your Mains Fed Water Cooler during the
Cryptosporidium outbreak. You can change the Filter and
sanitise at the next opportunity.
If you do not have our
Ceramic/Carbon Block Filter, stop using the Mains Fed Water
Once the Boil Notice
is lifted, sanitise the Water Cooler and replace the filter
before re-commissioning the Cooler.
a) Chemicals, such as CoolerClear Rinse and
CoolerClear Spray are the most widely
used Sanitising Systems, because they are simple to use,
effective, cost efficient and
b) Ultra Violet or Ozone Sanitising: These are
inbuilt systems which sanitise 24/7. The
- that these
Coolers are considerably more expensive
- that the UV light
source needs to be exchanged regularly
- that the UV light
does not penetrate into pipes and taps
- Both Cooler Trade
Organisations insist that UV and Ozone Coolers require
“manual” sanitising IN ADDITION every 6 or 12 months.
c) The Water
Trail or Removable Water Tank: This involves the removal of
internal water system, every 3 or 6 months. The
disadvantage is that every time the
internal water system is disturbed (disconnected and
re-connected) there is a risk of
creating a leak. The commercial disadvantage is the
cost and that one is “stuck” with a
single supplier for Water Trails and Removable Tanks.
d) What about Direct Chill? All Bottled Water Coolers
and most Mains Connected water
Coolers use a water tank system. In the case of Mains
Connected Water Coolers the
water tank is sealed with an air tight lit which
includes a 0.5 micron air filter.
Direct Chill Is only available for Mains Connected water
coolers. It has a totally sealed
water tank and the claim is that this avoids the possibility
of airborne contamination of
the water. The problem is that there is
- no evidence that
airborne contamination is even a problem, and
- the fact that
there is no independently tested evidence that Direct
Chill actually works. The counter argument is that it is
impossible to properly sanitise a totally closed system,
without opening it up to see what is going on inside.
that has been promoted is that Direct Chill provides more
cold water. This
is totally untrue – it confuses the fact that a small amount of water will be
quickly, but that these small amounts do not provide sufficient quantity
over an hour to
compete with the 3 litre cooling capacity of a conventional tank system.
e) What is Reverse Osmosis? R O is used in situations
where the mains water is not of
drinking quality or where the water is drawn from lakes,
rivers or the sea. The process
involves stripping the water of all minerals (which makes the
water taste bland) and
impurities. R O is a very energy hungry process and wastes
between 2 and 3 litres of
water for every litre of R O water it produces. It is for
this reason that any R O installation
requires prior approval by the local Water Authority.
R O is not required in the British isles, where the
mains water quality is of an excellent
before you buy.
