Poolfresh Special Features - Davey PoolFresh Instalación E Instrucciones De Funcionamiento

When the RED or ORANGE Operation LED indicates a fault, the output display will show the actual cell output to
indicate level of chlorination under the fault condition. (e.g. if the ORANGE Operation LED is on and the output is
showing 50% during the output duty cycle, that means the cell is only able to output 50% of the set output %).

PoolFresh SPECIAL FEATURES

SYSTEM CONTROL:
The System Control varies the amount of time the Cell operates during the filtration cycle.
The output duty cycle is controlled by a 10 minutes period cycle (e.g. Set point 40% = LED1, 2, 3 & 4 ON =
40% duty cycle = 4 minutes ON, 6 minutes OFF).
When the System Control is set to 0, the Cell will be OFF for the duration of the filtration cycle. When the
System Control is set to 100%, the Cell will be ON for the duration of the filtration cycle.
To turn the Cell OFF, simply reduce the output % to 0%. This will be convenient for backwashing. To turn
both power supply AND cell OFF, turn the ON/OFF to 0.
POLARITY FORWARD AND REVERSE (+/-):
These LEDs are used to check that the Cell current polarity is reversing. The forward direction is indicated
by a solid ON +/- LED and reverse by a flashing +/- LED. The Cell will operate in one polarity for a number of
hours so any change in these LEDs will happen slowly and depend on how the unit is operated.
LOW SALINITY INDICATION:
Your PoolFresh chlorinator is fitted with a number of protective systems including the Operation LED whose
primary function includes Low Salinity Indicator. As the salt level in the pool decreases, the wear on the
Cell increases. Although salt is not consumed in the Chlorination process, it is lost through splashing, back -
washing and on bathers as they leave the pool. The salt level is also reduced by rain, which causes dilution.
Salt is not lost to evaporation. As the salt level in the pool falls towards the minimum Operation LED will
turn ORANGE. At this point the salt level should be increased by adding more pool of salt to reach 3000-
6000ppm. The addition of salt should not affect the PoolFresh chlorinator as it is protected against overloads.
If no action is taken and the salt level continues to fall, damage to the system may result.
There are other factors that can cause the Unit not to work correctly:
1. Heavy Rain - can cause very dilute pool water to pass over the Cell due to surface skimming.
2. Scaled Cell - a scaled Cell will not draw as much electrical current as a clean Cell when first started.
Refer Maintenance of Electrolytic cell below.
3. Cold Water - cold pool water reduces the ability of a Cell to carry electrical current. Addition of salt can
help compensate for cold water. We recommend to switch off the unit when water temperature is below
15ºC. Low temperatures can damage the cell.
4. Failing Cell - as the Cell ages there will come a time when the electrical current draw will drop. This can
be compensated for with the addition of extra salt. A Cell is considered failed when it draws less than 80 %
of maximum current.
Please note that the Low Salinity Indicator is not like T.D.S. meters, which are temperature compensated
Scientific Instruments. The accuracy will be within 500ppm salinity and they are water temperature
dependent, just as the Cell is.
SAFETY NOTICE
IMPORTANT NOTICE: Certain local electrical regulations state "If the supply cord is damaged, it
must be replaced by a special cord available from the manufacturer or its service agent"
