After more than 14 days of standstill and before storing, the BlueBox 1200 must undergo a
complete cleaning process.
Please ensure that you have approximately 200 litres
of clean water available before you start the cleaning
process.
Cleaning procedure with Sodium
Hydroxide and Nitric Acid
(For example RoClean P303 and RoClean P111)
1
Remove the three filter housings and pull out the
filter cartridges. Mount the filter housings back
onto the mounts without the filters in.
2
Acid Cleaning (RoClean P303)
Dilute 1 kg of RoClean P303 in 50 litres of water.
Insert all three hoses into the container with the
cleaning fluid (Flush water outlet, Raw water
inlet and Clean water).
Start the BlueBox and let the system rinse without pressure (open the blue pressure valve) for
10 minutes.
3
Turn the blue pressure valve clockwise to show approximately 8 bars of operating pressure.
Run the BlueBox at this setting for 30 minutes.
4
Open the pressure valve all the way and run the system with clean water for 10 minutes
without pressure, and then again for 10 minutes with 8 bars of pressure.
5
Alkali cleaning (RoClean P111)
Dilute 1 kg of RoClean P101 in 50 litres of water.
Insert all three hoses into the container with the cleaning fluid (Flush water outlet, Raw water
inlet and Clean water).
6
Start the BlueBox and let the system rinse without pressure (open the blue pressure valve) for
10 minutes.
7
Turn the blue pressure valve clockwise to show approximately 8 bars of operating pressure.
Run the BlueBox at this setting for 30 minutes.
8
Open the pressure valve all the way and run the system with clean water for 15 minutes
without pressure, and then again for 15 minutes with 8 bars of pressure.

Turn off the BlueBox, following the procedure in ‘PART 3 After using BlueBox’.
If the first filter, 25 micron, is not too damaged (clogged), it can be rinsed and brushed down
and reinstalled.
NOTE For a thorough cleaning, please repeat step 2, 3, 6 and 7, 2-3 times and/or let the
membranes soak for up to 4 hours.
Preservation of membranes during storage or period of stand-still.
If the unit is to be stored (not used) for longer than 14 days, the membranes must be treated with
a 20 % glycol solution or RoCide preservation mixture, which will also protect it against freezing
temperatures. Remember to run a cleaning process of the system before taking into use.
IMPORTANT
The cleaning fluid must not exceed 45 ºC
The pH value of the cleaning fluid must remain within 2-11 pH
