5.1 Patented Temperature Compensation
WARNING - Failure to heed the following may result in permanent injury or death.
l Pool or Spa water temperature should not exceed 104 °F (40 °C).
The water temperature sensor works in conjunction with the purifier % feature to automatically
adjust chlorine output based upon changes in water temperature. This feature operates between
55 °F and 125 °F (13 °C - 52 °C).
As water temperature falls below 65 °F (18 °C), the controller will reduce the maximum output %
that can be selected. This feature prevents the controller from generating excessive chlorine in
cold water where it is not needed and prevents premature cell failure.
At 55 °F (13 °C) or colder water temperatures the controller will adjust to a fixed 1% output,
thus preventing over-chlorination and premature cell failure.
This feature is disabled when connected to an ORP controller and purifier output is set to 0%.
5.2 Water Manifold Assemblies - Available Options
5.2.a Automatic - Flow Bypass Manifold Assembly
The AutoPilot
®
manifold assembly is available with two (2), three (3), four (4), five (5), or six (6)
cells, including the Tri-sensor. Each cell must have a corresponding power module.
Example: If you order a PPP- 4 unit, there will be four (4) power modules in the control center and
a 941- 415AC manifold assembly with four (4) cells and one (1) Tri-sensor assembly.
The manifold is connected into the plumbing after all other equipment. Water from the pool / spa
is moved though the manifold by the circulation pump. Ensure there is enough flow to the
manifold base (min. 30 – 50 gpm / max. 70 gpm (min. 6.8 – 11.3 m³/hr / max. 22.6 m³/hr)).
The manifold uses four key components:
l
The Tri-sensor provides data (from electronic sensors) to the Pool Pilot
®
for monitoring water flow, water
temperature, and salt concentration level. The Pool Pilot
®
uses this data to determine if conditions are
suitable for the cell to operate; the signal read from the temperature sensor allows the automatic
temperature compensation feature to function.
l
The Cell (PPCx) receives power from the Pool Pilot
®
and converts the salt contained in the water to
chlorine.
l
The Strainer Screen prevents debris in the water from entering the Tri-sensor or cell and requires
periodic inspection and cleaning.
l
The Bypass Check Valve allows the water flow rate to be slowed and optimized through the cell while
permitting the pump to continue to circulate water to-and-from the pool / spa at full flow rates. The
reduced water flow through the cell results in a more efficient "Super-Chlorination” effect, resulting in
improved overall sanitization.
