The operating principle of the system is simple.
The edger cooling water is contained in the back tank of the Neptune filtration unit. These 25 litres of polluted
water during the day by edging residues are pumped into the front tank of the system when starting the
filtration cycle.
The front tank includes a filter bag with a 45 litres capacity which will retain the grinding residues: the 25 litres
of water and, as the filtration cycles accumulate, up to 16 litres of residues, which is on average equivalent to
1200 lenses.
When sending polluted water into the filtering tank, a portion of
this water is used to clean the walls of the working tank and its
bottom. When all the water is pumped into the filtering tank,
the pump stops and approximately 2 liters of filtered clean
water returns from the filtering tank to the working tank. This
water is used again to clean the walls, the bottom and then
returns to the filtering tank.
This cycle will repeat 10 times and will last from 10 minutes to
1 hour depending on the quantity of residues in the bag. As the
bag will fill up with residues, the cycle time will lengthen, but the maximum time will always be 1 hour or less.
The number of cycles in the allocated time will therefore become shorter. It is this count that will determine the
moment for changing the bag.
Although the cycle varies from 10 minutes to 3 ~ 4 hours, the total powered time is about 10 minutes, which
represents an average energy consumption of 0.11 €.

The cycle counter indicates the number of cycles that took place in 60 minutes with a maximum of 10 cycles..
When the filtering cycle is finished, a number from 0 to 9 or a letter P or G will be shown:
o The counter indicates 3 or below, it is time to change the filtering bag.
o The green dot 7 indicates presence of water in the working tank.
oThe counter indicates P, it is an error message. The return pump in the filtering tank has been working
continuously for 8 hours. See maintenance section.
o The counter indicates G, it is an error message. The main pump in the working tank has been working
continuously for 15 minutes. See maintenance section.
o The counter indicates no number or letter: the cycle has been stopped willing or unwillingly (power
supply failure, etc...).
oThe T2 LED indicates water in the filtering tank. During the filtering cycle it will turn on and off. This is
normal; it indicates that the water is filtered. This LED should never stay lit during the DAY use. If it is lit, it
indicates that water remains in the filtering tank.
This situation is abnormal:
1. Too much water in the tanks: as the tanks communicate trough a communicating hole in
their top, the filtering tank can never be emptied.
2. Edging residues have penetrated the filtering tank through the communication hole and
have potentially blocked the small pump located at the bottom of the filtering tank.
In both cases, remove the excess water, remove the filter assembly, clean the filtering tank and check the
return pump operation (TEST mode):
1. Press MODE switch to NIGHT
2. Press RUN and wait for the cycle start.
3. Press STOP
4. Press STOP again and maintain pressed. The return pump should start. If not, open it,
check the impeller, clean it and re-assemble.

Changing the filtering bag
The bag has to be changed every 1200 lenses on average.
Do not clean it !
When the cycle counter indicates 3 or less, the filtering bag has to be
changed within a few days, i.e. next week end.
In order to operate this operation as much comfortable as possible, it is
better to plan it in advance:
•Do not start the filtering status the previous day so that the bag is as dry
as possible (less heavy…)
•Prepare a garbage bag of 100 litres (22 Gal).
•Lift the filtering assembly and place it directly in the garbage bag.
•Remove the upper screws.
•Remove the metallic frame.
•Remove the filter, close the garbage bag and place it in the domestic
garbage.
•Install the new filter, make sure that the metallic frame “clips” the bag”.
•Tighten the screws back.
•Before re-inserting the filtering assembly, clean if necessary the tank,
check that the pump is OK and that the water presence switch is free to
move.
•Check the position of the grid support. It must "protect" the sensor N°1.
•Take advantage of this operation to verify that the nozzles of the
hydraulic system are not blocked.
•Check water level after one complete cycle.
•Cycle counter should indicate 9.
Maintenance
Reminder :
The filtering bag is a consumable
, it should be
changed approximately every 1200 lenses.
Reusing a bag after cleaning it will cause a failure in the system.

Changing the water
In order to maintain the best performance of the filtering system, it is recommended to drain the water at least
once a year. Depending of the nature of the water and the amount of edged lenses, it might be necessary to
perform this operation more often.
Draining the water is simple and has to be done when
changing the filtering bag:
oRemove the water receiver.
oConnect the supplied pipe as shown on the photo.
oConnect the pipe to a bucket or a water drain.
oEnter the TEST mode (see page 16) and hold down the
RUN button to start transfering the water into the
bucket.
oWhen finished, press MODE to return to the DAY mode.
oFill up the tank with fresh water. Pour a bottle of
SIDEROPTIC in the fresh water to decrease foam, the
"greasy film" adhering to the walls and prevent bacterial
growth. SIDEROPTIC is active until the water is not changed.
Hydraulic circuit cleaning
The hydraulic circuit can become clogged with edging particles, especially those of polycarbonate. At each
change of bag, check with the hand that the nozzles of the circuit are not blocked.
•Otherwise, clean nozzles as follows :
•Pull up the back cover
•Disconnect the cleaning hydraulic circuit.
•Check the nozzles
•if necessary, dislocate the pipes
(each pipe is glued at one end to
an elbow to facilitate reassembly of
the circuit). Clean the pipes with a
stiff wire.
• Reassemble the circuit and set
it back in position.

Pumps and sensors tests
All components of Neptune can be individually tested to diagnose a possible breakdown
•Filtration tank bottom sensor – Sensor N°1
This sensor indicates the presence of water in the filtering
tank. Its signal triggers the start of the return pump.
Its correct operation is verified by moving it manually and
checking the lighting and the extinction of the corresponding
T2 diode of the control box.
Warning: this signal is delayed and reacts slowly to the moving
of the sensor.
•Working tank water sensors – Sensors N°2
These sensors indicate the water level in the working tank.
They are located on the left side of the tank.
When it indicates MAX, the water cannot be returned from
the filtration tank to the working tank in order to avoid the
overflowing of the working tank.
Its correct operation is verified by moving them manually up
and down and checking the lighting and extinction of the
three diodes T1 (MIN, MAX and OK) on the control box.
Warning: this signal is delayed and reacts slowly to the
moving of the sensors.
•Filtering tank water presence sensor – Sensor N°3
This sensor is located at the bottom of the working tank and
indicates the presence of water in it
Its correct operation is verified by moving it manually in upper
position and simultaneously checking the on/off light of the LED 7
on the control unit.
Warning: this signal is delayed and reacts slowly to the moving of
the sensor

Their correct operation can be checked:
oPress the MODE button to switch to DAY mode
oStart the cycle by pressing the RUN button until the
corresponding red LED lights (min 3 sec.)
oStop the cycle immediately by pressing the STOP
button. NIGHT and DAY diodes blink.
oHold the STOP button to test the return pump.
If the pump does not start, then proceed with its
cleaning.
oHold the RUN button to test the main pump.
If the pump does not start, this is likely due to a locked
impeller. Remove debris of lenses or other materials that may be the cause.

Filtration (night) cycle does not start
The starting of the night cycle is controlled by the RUN button and the signal "presence of water" in the work
tank emitted by the water level sensor N°3 located at the bottom of the tank. With water, it must be set in the
high position.
1. Set TEST mode and check main pump.
2. Check that the sensor N°3 works: LED #7 should b e lit when there is water in the tank. If not, check
that the float is not affected in its movement by edging residues or obstacles.
The night cycle started normally and this morning the red light (RUN) is on and the counter shows the
letter "P".
The return pump from the filtering tank worked continuously for 8 hours.
•The water level is set to OK
Turn off power on the front side of the tank, wait several seconds and turn on again the tank. Monitor
the LED test on the control unit (they light up one after the other).
After this test, the control box must be in DAY mode, T2 LED off and water level OK. The cycle counter
will indicate a point, no number (no cycle has been achieved since power on).
If this is the case, the control software bugged during the cycle.
•T2 LED is on and the water level is on MIN
oCheck the filter tank pump as previously said
oCheck the hydraulic connection between the pump and working tank
oEnsure free movement of the water sensor in the filtering tank
The night cycle started normally and this morning the red light is on and the counter shows the letter
"G".
The working tank pump worked continuously for 15 minutes.
•Check that the floating sensorN°3 is not affected in its movement by edging residues.
•The impeller from the main pump is blocked.
Disassemble the body of the pump and remove the blocking material. Check the exhaust tube and
clean it with a stiff wire or a knitting needle.
The green T2 LED and the MAX LED are turned on although the filter cycle is finished
There is too much water in the entire system. Remove water from the working tank before restarting the cycle
at the end of the day. If necessary complete with water in the morning.
Beware; the filtering tank has probably been polluted by contaminated water from the working tank.
As soon as possible, while the filtering tank is empty after a filtration cycle (T2 LED off), remove the filtering
bag and clean the tank.
