Operation
These systems require a minimum level of maintenance to operate correctly. It is recommended that said maintenance
is carried out by expert personnel after reading these instructions.
These instructions are a guide for preventing problems following correct operation for some time or after a long shut-
down period. It is very important to check that the drainage microtubes are draining in each cycle and that the red
position indicators are changing, both on the Globo valves and on the filters. These indicators report which filters or
valves are not working correctly.
1. Place the system on a hard and flat surface, on its supports or connected to the piping system (depending on the
model), with suitable drainage to the external drain. Do not install the system in watertight spaces or underground.
2. Unpack and connect the different elements which are sent separately for transportation purposes; refer to the layout
and connection diagram to do so.
3. Connect the P+ and p- pressure microtubes to the controller, depending on the model.
4. Screw in the suction devices and direct the emissions as suitable. Water may rush out at first.
5. Do not directly connect the system to pumps or diesel generators that could cause breaks or cracks due to vibration.
Check that the flanges and gaskets are tight in all the system.
6. Adjust the inlets and outlets (flanges or screws) for wastewater and filtered water (P+ at the inlet and p- at the
outlet) in the correct direction. Use the labels and arrows indicating the direction of the water for guidance.
7. It is recommended to install manual shut-off valves (not supplied as standard) at the inlet and outlet, in order to
EN
isolate the system if necessary. Installing a check valve is also recommended, as well as, in some cases, a relief valve.
8. Connect the drain outlets of the cleaning valves to the external drain. There should be no pressure at this outlet,
and make sure that water is discharged to atmospheric pressure. The diameter of the drainage pipe should not cause
losses of pressure or build-ups of sediments that may block the system; place it downwards.
9. Check that the electrical supply available is stable and the voltage matches the one required by the controller. Install
thermal magnetic circuit breakers and other protection elements according to the legislation of each country. To avoid
the risk of electric shock only handle the inside of the controller when it is disconnected from the mains.
10. The filters must be placed afer the pump station, they must never placed before the pumps. To filter downwards,
automatic valves that maintain the pressure must be installed.
11. The minimum pressure required for operations is 1kg/cm². In some cases the manual outlet valve (not supplied
as standard) must be closed to obtain this minimum pressure level.
12. Check that the quality of filtration required is the one obtained by examining the filtering element. It is recom-
mended to install satellite filters near to the point of use, as a safety measure for avoiding the build-up of particles or
loose objects inside the pipes of the system during the transportation of the water to the destination.
13. The duration of cleaning or backwashing cycles depends on each model, the equipment, pressure levels, and val-
ves used. The following cleaning times are recommended, which should be increased according to the pollutants and
wear over time:
• Recommended minimum cleaning time for filter models AutoSenior, Rotativos, MasterMegadisc and AutoMaster.
- With 2" and 3" Globo valves without Cebollo valve--> 35 sec.
- With 2" and 3" Globo valves with Cebollo valve--> 20 sec. (for Vip stations, 45 sec.)
- With 4" and 6" Globo valves (two 4" valves) with Cebollo valve--> 45 sec. and 60 sec. respectively.
14. The most important information can be found in the table on page 3.
15. The working pressures of this equipment have been tested at 23º C in standard conditions. The use of the equip-
ment in extreme temperatures is not recommended, please contact us for further questions.
