The pool’s chemistry must be balanced BEFORE activating the Aqua Plus’s optional chlorinator function. NOTE: If
the pool does not have new water, add metal remover and non-copper based algaecide to the pool, per manufacturer’s
instructions. This ensures a quick, troublefree transfer to the Aqua Plus system.
Salt
Salt Level
Use the chart below to determine how much salt in pounds or (Kgs) should be added to reach the recommended
levels. Use the Pool Sizing Formula on page 4 (measurements are in feet/gallons and meters/liters) if pool size is
unknown.
The operating salt level is between 2700-3400 PPM (parts per million) with 3200 PPM being optimal. Before adding
any salt, test the salt level. This is especially important for retrofit installation to older pools where all of the chlorine
added to the pool over time is ending up as salt. If the level is low, determine the number of gallons in the pool and add
salt according to the chart below. A low salt level will reduce the efficiency of the sanitization and result in low chlorine
production. A high salt level can cause the Aqua Plus to stop chlorinating. The salt in your pool/spa is constantly
recycled and the loss of salt throughout the swimming season should be minimal. This loss is due primarily to the
addition of water because of splashing, backwashing, or draining (because of rain). Salt is not lost due to evaporation.

Valve3 Function
Timeclock (default)
– the valve turns on/off at the times set for the valve3 timeclock in the Timers Menu
(see Operations Manual). The VALVE3 button can also be used to turn the valve output on or off.
Solar
– the valve operates when the filter pump is running and solar heat is available and the water is less
than the desired temperature setting. Solar heating must be enabled in the “Solar Config. menu for proper
operation to occur.
In-Floor Cleaner
– the valve switches the water returning to the pool between the in-floor cleaner and the
normal return jets which facilitate efficient surface skimming. The valve will operate the in-floor cleaner for
the first half of each clock hour and then switch to the jets/skimming for the last half of the hour.
Super Chlorinate
– if “Chlorinator” is enabled, this option allows the user to start a Super Chlorinate cycle
when the Valve3 button is pressed, rather than using the Settings Menu. Note that only one button can be
assigned to this function.
Valve3 Interlock
If “Enabled”, this feature will override the function (timeclock or in-floor cleaner) selected above and turn
the valve off when: the filter pump is off, first 3 minutes of filter pump operation (allows the pump to prime
and get water flowing), or for the first 3 minutes after solar turns on (allows air in the solar panels to be
purged). Interlock is not available for solar or super chlorinate.
Valve3 External Input Interlock
When Valve3 External Input Interlock is enabled, the Valve3 output will be forced off when the external
input is active. This will have precedence over freeze protection. Valve3 External Input Interlock is not
available for solar and super chlorinate.
Valve3 Freeze Protection
This function protects the pool and plumbed equipment against freeze damage. If Freeze Protection is
enabled and the AIR temperature falls sensor falls below the selected freeze temperature threshold, the
Aqua Plus will turn on the valve to allow circulation of the water. IMPORTANT: this only enables
operation of the valve3 output during freeze--see the “Filter Pump Config.” menu to enable freeze protection
for the main circulation system.
Valv
e3 Pump Speed
This is the speed of the pump when the Valve3 output is on. The default selection is “Settings Menu”.
This is the speed of the pump that has been selected in the Settings Menu for normal filter operation. If an
alternate speed is desired when the Valve3 output is on, push “+” or “-” and select from “Filter Lowest” to
“Filter Highest” in 5% increments.
