Buffer Delay
: This
function will stop the
unit dosing acid for 6
hours of filtration.
ALWAYS USE THIS FUNCTION AFTER ADDING
BUFFER (ALKALINITY INCREASER / SODIUM
BICARBONATE) TO THE POOL, TO REDUCE THE
AMOUNT OF BOTH ACID AND BUFFER USED.

The
AUTO / OFF

The dose setting is used to set the acid pump
addition and waiting times, and are related to how
quickly the pool turns over the water. This is related
to both pool size, and pump/pipe setup.
In general, a smaller pool would use a lower Dose
Setting than a large pool. However other factors can
affect this, such as pool turnover time.
As a guide, use the following setting as a STARTING
point when the unit is first installed :
1....Up to 75,000 L / 20,000 Gallons
2....75,000 to 150,000 L / 20,000 to 40,000 Gallons
3....150,000 to 250,000 L / 40,000 to 65,000 Gallons
4....250,000 to 500,000 L / 65,000 to 130,000 Gallons
5....>500,000 L / 130,000 Gallons
For pools under 25,000 L (6,500 Gallons), be sure to
dilute the acid at 8 parts water to 1 part acid (page 5).
For pools with a wet edge and balance tank, use a
setting of 1 lower than listed for the pool size.
If the pH BOSS does not keep up with acid demand,
and the Alarm sounds, increase the dose setting by
one step and check in 2 days.
If the alarm is tripped due to low pH, reduce the dose
setting by one step and check in 2 days.
NOTE ABOUT DOSE SETTING FOR NEW POOLS
New concrete/pebblecrete, marblesheen and
quartzon pools can have very high pH level for the
first 1 to 3 months of operation. Readings of pH10 or
even higher are possible. Even when the pH is
brought down to the correct pH7.4, the pH reading
will still drift back up over the following hours or
days.
The acid demand during the initial period could be as
high as 1 Litre (1 Quart) of acid per 10,000L (2,500Ga)
of pool water per day. This acid demand will
gradually reduce over the first 1 to 3 months.
If the pH BOSS is not able to maintain pH at the pH7.4
set point, please increase the Dose Rate setting to a
higher value. This will add more acid in each dosing
cycle, and therefore be able to control the pH during
this high acid demand period of time.
