[IMPORTANT NOTE]
Please be aware of the following:
Make sure that the electricity supply is stable.
The purification membranes in the Bluebox 1800UF 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 (cero) degrees Celsius can
ruin the 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 www.pureh2o.net

As an industrial standard for Reverse Osmosis, membranes output decreases with
temperature of raw water. (3% reduction per 1 degree C measured from 25 degree C)
The industrial standard for Ultrafiltration membranes shows a lesser effect from colder feed
water, but the capacity should be expected to be reduced.
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.
