FURTHER INFORMATION
• Should power be interrupted for any reason, the controller will resume normal operation when
power is restored.
• Degree of protection against moisture: IP33.
• Store pool chemicals safely, at least 1.8 metres away from all pool equipment.
• MAX combined rated input load for the JVA socket is 24Vac at 1.2Amps.
• The pool size and the proximity to the pH & ORP Set Points determines how long (in seconds)
the pump will actually dose for.
• The length of time between one dose of acid and the next is approximately 30 minutes. This
gives the pool water a chance to mix properly and create a true reading before the next dose is
administered. This helps to ensure that overdosing doesn’t occur.
• The pH dosing pump will inject the acid into a spa for either 2 or 4 seconds per dose. The
amount of dosing time will depend on the size of the spa.
• The pH dosing pump will inject acid into a pool at a time range of between 4 and 50 seconds
per dose. The amount of dosing time will depend on the size of the pool. The larger the pool,
the longer the dosing time.
• On the Home screen of the Oasis Smart App, pH readings will only be displayed of a value
between 5.5 to 8.5. If the reading is outside of this range, the App wil display either, <5.5 (check),
>8.5 (check), or
–-(check).
• The Smartchem will be able to read a pH range of 0 (strongly acidic) to 14 (strongly alkaline)
but any reading outside of the 5.5 to 8.5 range will only be displayed in the Chemical Setup
option of the menu.
• ORP readings on the home screen of the Oasis Smart App will only be displayed where the
value is between 300 to 800. If the reading is outside of this range, the App wil display either,
<300 (check), >800 (check), or
–-(check).
• The Smartchem will be able to read a ORP range of 0 (little to no Chlorine) to 1000 (possibly
over chlorinated) but any reading outside of the 300 to 800 range will only be displayed in the
Chemical Setup option of the menu.
• In the Chemical Balance window on the home screen of the Oasis Smart App, the status text
will display whether the pH or the ORP readings are ‘Low’, ‘High’, or ‘Normal’ in comparison to
the Set Points for both.
• If for either the pH or ORP levels, ‘---' is displayed, this is indicating a missing/faulty probe or an
invalid reading. A water sample test is advised at this point.
• The Sensor & Injection Manifolds suit 50mm pipe, 4 reducing bushes will be required if you are
installing the manifolds into 40mm pipe
• If the pool system is to shut down for a lengthy period of time (eg; repairs to the pool surface),
it is recommended that the pH & ORP probes be removed from the Injection Manifold and be
stored appropriately. This involves putting storage fluid (20% KCI) into the small bottles the
probes came in, putting the probes into the fluid, and screwing the nut to the top of the bottle.
o
If you don’t remove the probes and put the pH & ORP probes into the storage solution,
the probes may be damaged and they won’t be covered under warranty.
