7) Do not use any metallic objects to scrape the blade surfaces or you will remove or damage
the blade sensor coating.
6.2.3
Cleaning Tri-sensor/Salt Sensor
If required, you can remove a calcium scale buildup by creating a solution of water and muriatic
acid
as follows. Do not use any metallic objects to scrape the blade surfaces or you will remove
or damage the blade sensor coating.
WARNING:
Failure to heed the following may result in permanent injury or death.
CHEMICAL HAZARD - To avoid damaging splashes always add acid to water, never
water to acid. Wear appropriate personal safety protection including safety glasses
when using pool chemicals.
1) Mix the solution in a small container tall enough to cover the sensor blades.
DO NOT
add
water to acids; always add acid to water in container.
2) Mix one (1) part muriatic acid into four (4) parts water.
3) Immerse the salt sensor blades in the solution for up to 15 minutes. An effervescing
action indicates the calcium is being dissolved from the blades.
4) Rinse with fresh water and re-inspect. Repeat the acid treatment as necessary until all
scale has been eliminated.
6.2.4
Test Tri-sensor Flow Switch
WARNING:
Failure to heed the following may result in permanent injury or death.
Do NOT operate system with a faulty water flow switch.
The Flow Switch is a critical equipment protection device to prevent damage to the cell or
system. When water flow has stopped, power to the cell is automatically turned OFF. It is
important to verify the proper operation of the Tri-sensor
’s water Flow Switch protection device.
The following procedure can be used to verify the proper operation of the flow switch, or to flush
debris from the Bypass Valve.
1) Turn off the circulation pump.
2) Slightly loosen the union nut just below the
cell on the side of the manifold that does not
contain the filter screen. (A strap wrench may
be required.)
3) Completely loosen the manifold union nut that
contains the filter screen and pivot the
manifold to gain access to the filter screen.
4) Remove the screen. Clean the screen if dirty.
5) If the screen was dirty, then the system may
need to be purged to remove excess
debris. Leave the manifold off and run
the pump for a few seconds until
clear.
