IMPORTANT NOTE
Please be aware of the following:
• Make sure that the electricity supply is stable.
• The Reverse Osmosis membranes (RO filters) in the BlueBox system normally have to be changed
every 2 years depending on the working hours and quality of feed water.
• Please do not place the system in directly sunlight. Heat may affect the electronics in the switch
board box.
• As the UV-light contains glass, the system must not be affected by hard shock.
• The system must be free of dust and dirt.
• The system must not be exposed for frost. Temperatures below 0 ºC (zero degrees Celsius) can ruin
the RO membranes. E.g. during a long-haul flight, the BlueBox should be started with low pressure
for a while in order to defrost the membranes without damaging them. For long term storage in
freezing temperatures, please contact Much More Water at [email protected].
• As an industrial standard for Reverse Osmosis, the output of the membranes decreases in
proportion with the temperature of the raw water: 3 % reduction per 1 ºC measured from 25 ºC.
• Beware of silt, humus and high levels of iron in the raw water. These compounds will eventually spoil
the membranes, since very small ‘plates’ from these compounds will fill up the membranes over
time. The only way to deal with this is to install an improved pre-filtration system.
• Beware of high content of iron/manganese. Especially coming from boreholes, high levels of iron
and manganese will clog the membranes and render them useless. It may be advisable to install an
improved pre-filtration system, using anti-scalants.
