• REPLACING THE PH-CLEAR PUMP COMPRESSION TUBE (EES PRO ONLY)
After installation, every 180 days the device will
display the message ACID PIPE, recommending
replacement of the pH-Clear peristaltic pump
compression tube.
Refer to paragraph X for the tube replacement
procedure.
After replacing the tube, reset the counter as
follows:
• Press the button M four times
• Press the arrow
and 180 DAYS are displayed at the bottom of the
screen
• The 180 days interval may be reduced in 10 day
increments using the arrow keys.
•
button.
• PUMP DISCONNECTED (EES PRO ONLY)
If the system tries to activate the pump while the
pump is disconnected, the message NEED PUMP
is displayed at the bottom of the LCD screen.
Cut power to the electrical/ control
panel, open the lid of the connection terminal
compartment, check the condition of the
connector contacts, the two wires coming out
of the cable and the connector pins, then put
the connector back into position, taking care to
push it in fully and the right way around.
Inspect the length of the pump cable and
make sure that it is not damaged.
• HIGH AND LOW PH AND REDOX ALARMS (EES PRO ONLY)
PH HIGH: this message is displayed when the pH
value measured by the pH probe is greater than 8.5
(NB: this warning will not stop injection of acid
by the pH-Clear pump).
resolve the problem by carrying out the following
steps in the order indicated (if the problem is not
Make sure that the pH set point is correct.
Check that there is enough acid in the buffer
tank
Check that the pH Clear motor is working
disconnect the injection tube from the injector,
put the tip into an empty container and restart
the pump)
Verify the accuracy of the pH probe by
measuring the pH of the pool water using a
recently calibrated photometer that measures
pH. If there is a difference of more than 0.2 pH
units, calibrate the pH probe and check again.
If the values measured by EES and the
photometer correspond, and the pH is above
8.5, adjust the pH back to the set point by
adding acid and wait to see if this phenomenon
reoccurs.
PH LOW : This message is displayed when the pH
measured by the pH probe is less than 6.7.
resolve the problem by carrying out the following
steps in the order indicated (if the problem is not
Make sure that the pH set point is correct.
Check that the pH-Clear pump stops
injecting acid when the pH falls below the set
point.
Check that the probe is clean and
undamaged.
Verify the accuracy of the pH probe by
measuring the pH of the pool water using a
recently calibrated photometer that measures
pH. If there is a difference of more than 0.2 pH
units, calibrate the pH probe and check again.
If the values measured by EES and the
photometer correspond, and the pH is less
than 6.7, add base to bring the pH back to the
set point and wait to see if this phenomenon
reoccurs.
ORP HIGH: this message is displayed if the value
greater than
925 mV .
resolve the problem by carrying out the following
steps in the order indicated (if the problem is not
correct.
Check that the device is not in Turbo mode
and that it is not producing Chlorine
Using a recently calibrated photometer,
measure the concentration of free Chlorine in
the pool water to see if this value corresponds
displayed.
