SALTWATER SYSTEM OPERATION
1. Start up the unit:
Plug the power cord into the electrical outlet and test the
GFCI/RCD (circuit breaker). Switch on the unit.
With the Filter Pump turned "ON" and operating. The
green "Pump" light on the control panel will be on
and flashing code "00" appears on the electronic control
station's LED, indicating that the unit is ready to be
programmed. This is normal.
2. Set operating hours for Saltwater System:
With code "00" flashing, press
set the desired operating hours. See the
"Operating Time Table" for the required
operating hours related to each pool size.
Pressing will increase the time from 01
to 12 hours maximum. If you have selected
too many hours keep pressing
the cycle. The built-in timer will now activate
your Saltwater System, at the same time each
day, for the number of hours you have set.
NOTE: The Saltwater System will not
operate if the filter pump is not operating.
3. Lock keypad controls:
With the desired hour value showing, press
until you hear a "beep". The green "WORKING"
indicator on the control panel will light up within a few
seconds to indicate that the saltwater system has started
sanitizer production. Locking the control buttons into this
setting prevents unauthorized changing of the operating
cycle.
NOTE: If you forget to lock the keypad controls, the
system will automatically lock it and start working 1
minute later.
4. Unlock & Readjust operating time if necessary:
The operating hours can be re-adjusted if necessary.
Press button until you hear a "beep" to unlock the keypad and the
current programmed time will flash.
Repeat steps 2 to 3.
5. Test the copper concentration in
the pool water.
The Saltwater System recommends
a copper level of 0.1 to 0.2 ppm.
This is easily tested by the copper
ion test strips provided. If the test
result is 0.1~0.2ppm, go directly to
