*** IMPORTANT NOTICE ONZEN V8 ***
ese cells are considered a consumable item and are now designed to be replaced by the customer in order to be
more user friendly. DO NOT GET THE INTERNAL CONNECTION WET!
To change your salt cell remove the set screw on your salt cell with a Phillips screwdriver. Now unthread the salt
cell from the housing turning counter clockwise. is will require you to use your muscles as the cell is threaded
in quite tight to prevent any water from getting on to the 12 volt connection. Before threading in the new cell
put a generous amount of dielectric grease in and around the 12 volt connections in the centre of the housing
and on the end of the cell. Now thread the new cell into the housing. ere is a notch built into the threads
that will stop the cell precisely where the set screw needs to be installed. If the cell is changed under water the
connection will get wet and corrode. e corrosion will destroy the connection between the salt cell and the
salt cell housing. is corrosion will be visibly noticeable upon inspection. Warranty will be void If corrosion
between the salt cell and salt cell housing is detected.
Onzen Questions Continued
Question 8: What should I do if the spa is not going to be in use or when I go on vacation?
(please see FAQ #3)
Question 9 Should I use Best Defence or another scale remover?
It is recommended that calcium be removed from the water in advance rather than adding a scale remover after
the fact.
Question 10: What is the impact of phosphates on the Onzen system?
High levels of phosphates (above 250 ppb) may reduce the effectiveness of sanitizer output. Question 13 What
happens if my water becomes cloudy?
1. Test the water for chlorine content. If the level is low add Boost.
2. Check your lters as they may require replacement.
3. Check you pH level you may need to adjust you pH down.
Question 11 : Can I use softened water with my Onzen system?
Yes. You probably have a water softener because your water is quite hard. Your water-softener removes calcium
from your water and helps you achieve water with calcium content near the target range, between 50 - 150
ppm.
Question 12: Prior to draining spa water for refill purposes should any form of system flush be
carried out?
Yes you can, Arctic Pure ‘Fresh Start’. Use in accordance with the instructions on the container. Flushing the sys-
tem components and hoses is helpful when you get biolm and calcium build-up.
It is good practice to do this at least once a year.
