Emptying the Treatment Tank procedure (in case of Tank Overflow Alarm)
In the case the ECOmar S STP goes into system fault for Tank Overflow Alarm, it will be necessary to empty the Treatment
Tank. The tank can be emptied resending the untreated liquid back the on board sewage collecting tank; or discharging the
untreated sewage directly overboard, according to IMO/MARPOL regulation. The untreated liquid can be discharged
overboard only when permitted by the IMO/MARPOL regulation.
To empty the Treatment Tank, discharging the untreated sewage, follow this procedure:
1.
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).
2.
Set the 3-way ball valve (H) (refer to figure below and to attached flow diagrams), in the discharge position;
3.
From the Tank Overflow Alarm flashing screen
(refer to the
Alarms Description
section) press the key
▼/F2-MAN on
the Main Control Box, to start the automatic emptying of the Treatment Tank;
4.
Wait until the automatic emptying of the Treatment Tank ends. It will be signaled by the visualization of the following
screen on the Main control box:
5.
Re-set three-way ball valve (H), in to ECOmar S operation position (refer to figure below and to attached flow diagrams);
6.
Press the STOP/ESC key on the Main Control Box, to return to the system main page.
7.
Reset the plant in
automatic mode
(refer to the

Winterizing procedure
When the ECOmar S plant has to be stored or set out of service for a long period, it is necessary to perform a special winterizing
procedure to avoid any problem at any further system start up and to preserve the plant components and performance.
To perform a Winterizing procedure for the ECOmar S STP follow the steps, listed below:
1.
Empty completely the system, no liquids presence may remain inside any parts of the system;
1.1.
Activate necessary treatment cycles to empty the collecting tank (your supply);
1.2.
Switch the system to manual mode as described in the
Manual mode
section;
1.3.
Activate the macerating pump till the pump is suctioning air (recognizable by a different noise), to totally empty
the Treatment Tank. Otherwise it is possible to verify the tank emptying, by checking from the inspection flange;
1.4.
Use the drain plug (item
A
on the picture below), located at the bottom of the tank to discharge any residue;
2.
Empty all the hoses connected to the ECOmar S STP;
3.
Empty all the system pumps unscrewing the plugs located at the bottom of the pump body, with a suitable wrench;
