The storage conditions of the Zeolite must be those indicated in the related safety data sheet. If any abnormal condition,
indicated in the safety data sheet, occurs the media is no longer effective, therefore replace the media (refer to the item
safety data sheet).

If the temperature exceed 0÷50 °C uninstall the U.V. Sterilizing System, and store in a safe place at a temperature from
0°C to 50°C;
24.
If the temperature exceeds 30÷60 °C range, store all the supplied Level Probe Control Box in a safe place at a temperature
from -30°C to 60°C.
25.
If the temperature exceeds 1÷100 °C range, uninstall the supplied level probes from the collecting tank and store them in
a safe place at a temperature from 1°C to 100°C.
26.
Unscrew all screws obtaining a moment of torque up to 10-12 Nm, if out of 0÷55 °C temperature range.
12.3.1
Washing the treatment tank
Periodic cleaning of the Main Unit Treatment Tank is recommended (at the end of the season or when you plan a long period
shut down for the ECOmar S STP, however, depending on the state of scale deposited) to avoid possible deposits of solid
material that may hinder the correct operation of the plant.
To perform a Treatment Tank cleaning procedure, follow the steps listed below:
1.
Go to the main page of the Main Control Box (refer to
Manual mode
section);
2.
Set the plant in manual mode by pushing the
▼/F2-MAN key (refer to
Manual mode
section);
3.
Go to "
3-WAY VALVE V1
" page, and then open the valve by setting it to ON (refer to
Manual mode
section);
4.
Wait for the complete opening of the three-way valve (about 40 seconds).
5.
Go to "
3-WAY VALVE V2
" page, and then open the valve by setting it to ON (refer to
Manual mode
section);
6.
Wait for the complete opening of the three-way valve (about 40 seconds).
7.
Go to "
SEAWATER PUMP
" page, and then starts the sea water pump, setting it ON (refer to
Manual mode
section);
8.
Wait for no longer than 30-40 seconds to allow the washing of the ECOmar S treatment tank by the sea water pump;
9.
Stop the sea water pump, setting it OFF (refer to
Manual mode
section);
10.
Make sure that a your supply 3-way ball valve (H) , installed between the sludge discharge outlet of the Sludge
Discharge Valve (V2) and the inlet of the Sludge tank, is correctly connected to the collecting tank or to an outboard
discharge (the untreated liquid can be discharged overboard only when permitted by the IMO/MARPOL regulation).
11.
Set the 3-way ball valve (H) (refer to the
Emptying the treatment tank procedure
), in the discharge position;
12.
Go to "
MACERATING PUMP
" page, and then start up the pump, setting it ON (refer to
Manual mode
section);
13.
Then wait until the tank is full empty, checking the liquid level inside from the inspection flange installed on the top of
the treatment tank of the ECOmar S Main Unit (refer to attached G.A. drawing);
14.
Stop the macerating pump, setting it OFF (refer to
Manual mode
section);
15.
Check the inside of the treatment tank and repeat steps 7 to 13 of this procedure, if necessary;
16.
Close the three-way valve (V1), by setting it OFF (refer to
Manual mode
section);
17.
Close the three-way valve (V2), by setting it OFF (refer to
Manual mode
section);
18.
Set the 3-way ball valve (H) (refer to the
Emptying the treatment tank procedure
), in the operation position;
19.
Return to the system main page (refer to
Manual mode
section).
At this point the treatment tank is clean and the ECOmar S plant is ready for start the normal operation.
12.3.2
Washing the Level Sensor of the treatment tank
When you plan a long period shut down for ECOmar S plant, it is recommend to perform a cleaning of the level sensors
installed on the Treatment Tank of ECOmar S Main Unit.
If the plant is supplied with a Multi-level (ball type) Sensor (ECOmar 20 S-32 S-45 S-70 S-145 S); to clean the level probe
installed inside the ECOmar S treatment tank, remove it from the top of the treatment tank, by uninstall the relative flange
(refer to the attached G.A. drawing) and disconnect it form the Main control Box. Once the multi-level probe is removed from
the system, accurately wash it with fresh water. Finally re-install the Multi-level probe on the tank and connect it to the Main
Control Box (refer to attached Electrical Connection Diagrams).
