Salt Requirements
It is important that with typical pools, a salt residual of 2500 to
4
500 ppm (2,5 – 3,5 g/l) be maintained at all times for peak
efficiency. The
Pool Pilot
®
Soft Touch
can also handle special application salt levels of up to 35,000 ppm (35,0 g/l) without
any adverse effects to the unit.
NOTE:
HIGH Salt level does not affect purifier production but can cause corrosion problems with metallic fixtures, light
rings, ladders and handrails.
The amount of salt required depends on the size of the pool and the present salt level. As the salt is being added, we
recommend running the circulation pump continually for 24 hours with the main drain opened. Brushing the salt towards the
bottom main drain will assist in the dissolve rate and prevent possible staining with certain types of salt.
We recommend the use of
AutoSoft
Plus™
Water Conditioning Salt.
AutoSoft Plus™
salt contains 99.8% pure Sodium
Chloride (NaCl) without Iodine or the Anti-Caking additive, Yellow Prussiate of Soda (YPS). Iodine and YPS can cause a
localized tint to the water or yellow staining on the cementitious finish if allowed to rest undissolved on the finish for extended
periods of time.
AutoSoft Plus™
is blended with the proper amount of stabilizer to maintain a proper level within the
recommended range when added according to the salt chart on the box.
Granular Salt, Table Salt, Solar Salt or Water Conditioner Pellets can also be used but will have different dissolve rates. If the
salt you use contains Iodine or YPS, constant brushing will help the dissolve rate and prevent staining due to the additives in
the salt. Ensure that the salt you use contain a minimum purity of 99% Sodium Chloride (NaCl).
NOTE: Do not use Rock Salt due to its high levels of impurities.
TEST YOUR WATER FOR SALT LEVEL FIRST
with the provided salt test strips,
and then use the chart below to determine the amount of salt to add.

Start Up Procedures
Keep the Output Setting on your
Pool Pilot
®
Soft Touch
on 0% (OFF) until you get your water clear, blue and properly
balanced.
1.
After balancing your water chemistry according to the Water Chemistry Parameters shown on page 9, add the proper
amount of salt (see Salt Requirement Chart above) and circulate 24-hours prior to starting your
Pool Pilot
®
Soft Touch
.
2.
The following day, turn your Output Level to 50% and operate normally. For the first two weeks, test the water every 2-3
days for proper Purifier levels. Raise or Lower the Output Control Setting as needed, according to your test results.
3.
Once your Output Level has been established, you will only need to adjust your chlorine level according to increased
bather usage by increasing the Purifier Output % or by using the Boost button.
