Display Message:
“CHECK SALT”
Salt level too low Check salt level and add salt if required.
Temperature too low When water temperature is below 25ºC the cell
may not be able to produce at 100%.
Calcified or blocked cell. Visually
inspect cell for a build up of white
calcium or other deposits / debris
between plates.
Refer to CELL MAINTENANCE section.
Display Message:
“CHECK SALT (OFF)”
Very low salt level, unit will not
produce chlorine to protect cell
from damage
Check salt level and add salt if required.
If salt level and water
temperature are normal and cell
is clean, this may indicate a worn
cell.
Have cell checked and replace if necessary
Display Message:
“HIGH SALT”
Salt level too high This is a warning only. Chlorinator will be
operating normally unless the
“HIGH SALT (OFF)” message is displayed (see
below). Do not add any more salt. Top up pool
with fresh water if possible.
High Water temperature A combination of a high salt level and high
water temperature can trigger this warning. No
action is required unless the
“HIGH SALT (OFF)” message is displayed (see
below).
Display Message:
“HIGH SALT (OFF)”
Very high salt level detected,
possibly combined with high
water temperature. Cell has shut
down to protect from damage.
Check salt level in water. If salt level is too high
you may need to pump some water to waste
and then top up pool with fresh water. Consult
your local swimming pool professionals for
advice on this procedure.
Display Message:
“SPA FLOW DET'D”
The flow switch on the spa
suction line triggers this
message. This message
indicated chlorine production is
inhibited while the spa is in use to
prevent over chlorination.
No action required if valves are intentionally
positioned to circulate spa water only.
If spa is not in use, check that the spa suction
line valve is positioned correctly (closed).
If the spa suction line valve is
closed and has no flow, then the
spa flow switch may be jammed
or faulty
The flow switch can become jammed or broken
if an object or debris is allowed to enter the spa
suction line. You may require a technician for
assistance.
