7.
Use the white 10 metre (30 foot) product water
extension hose to fill multiple tanks without the need to
move the desalination system. Use the push-fit joiner
provided.
Product water flow will vary depending on several
factors, including temperature and salinity. Warmer or
lower salinity water will lead to higher levels of product
water output. Natural membrane variability and other
factors will play a role in product water output.
As a guideline every degree Celsius increase in water
temperature, product water flow increases approximately 3%.
Shutdown - Portable
1.
To switch the unit off, first slowly turn the pressure control valve in an anti-clockwise
direction until the pressure reads less than 20 bar (300 psi).
2.
Switch off the PSU.
3.
If you intend to flush or pickle your system, refer to the

section below.
4.
Replace the cap on the intake hose to keep the unit primed during storage.

Replace the rubber boots on each of the other hoses to keep the system clean and prevent
water dripping while stowed.
6.
Wait 60 seconds for internal pressure to dissipate before disconnecting the black high-
pressure hose from the Pressure Supply Unit.
7.
Rinse the strainer in fresh water before storage.
Switching off the PSU while system is under pressure will cause pressure shock to the
membranes and may damage them.
Shutdown - Installed
1.
Slowly turn the pressure control valve in an anti-clockwise direction until the pressure reads
