OPERATION (cont’d)
Additional notes:
a)
For proper sanitation, spa must be completely drained periodically. The number of days between COMPLETE SPA
DRAINAGE is equal to the volume of spa water in liters, divided by 10 times the maximum number of daily spa
users.
b)
Maximum spa usage temperature is 40°C (104°F). Duration in spa water at 40°C should not exceed 15 minutes.
c)
Heavy use of the spa (excessive contamination) may require longer recovery times (A return to a minimum of 3 ppm
chlorine/bromine). Recovery time may be reduced by adding a shock compound to the water.
d)
Hot weather, heavy pool usage, and rain may require a higher output to maintain proper sanitizer residual.

TRI-SENSOR ASSEMBLY
The Tri-sensor assembly tests for Flow, Salt and Water temperatures. A minimum flow rate of 94.5 L/min. (25 US
Gallons/min.) is required to activate the flow switch. As the water flow closes the paddle, a magnet activates a micro switch to
verify proper flow. The Salt sensor protects against low salt levels and the temperature sensor protects against cold water
temperatures. Both of which can contribute to accelerated cell failure.
Remove the Tri-Sensor as follows (with pump off):
Remove both screws from the side of the Tee Assembly. Firmly grip
he Tri-Sensor assembly and twist to loosen the compression o -ring.
With the aid of large Channel-lok® (or similar) pliers, twist
back and forth while removing the Tri-Sensor from the tee.

Take care not to twist or tweek this paddle, which can cause

inaccurate flow readings. Inspect the salt sensor blades for scale
and debris and clean if necessary. See page 12 for cleaning
instructions. Follow the directions for Manual Cell Cleaning.
Check the tri-sensor assembly for any damage to the plastic
housing and replace if needed.
