4.  Make holes of suitable diameter for the coupling device fixing slots and secure it firmly to the bottom of the tank using chemical or expansion 

plugs.  Use stainless steel metal fasteners or protect the screws and nuts with a suitable product to prevent corrosion.

5.  Connect the outlet pipeline to the coupling device.  A shut-off valve and a ball type check valve with full free passage should be installed using 

a connection pipe with length equal to at least 5 times the diameter of the outlet.

6.  Fit the pipe guides, cut to the correct length, to the coupling device. Galvanised steel pipes, or preferably stainless steel pipes, of suitable 

diameter can be used (see technical information).

7.  Connect the spacer bracket to the top end of the pipe guide and mark the positions of the holes required to fix it to one of the sides of the tank; 

make sure that the pipe guides are perfectly vertical with the aid of a plumb-line or a spirit-level.

Before connecting the bracket spacer check, by lifting the pump up, if it is possible to extract the coupling flange from 

the pipe guides (Fig. 11).

8.  Make holes of suitable diameter for the spacer bracket fixing slots and secure it firmly using chemical or expansion plugs. Protect the screws 

and nuts with a suitable product to prevent corrosion.

9.  Clean the tank to remove any remaining debris and waste.

10. Secure a chain or sling of suitable size to the handle and lower the pump into the tank, sliding the flange along the pipe guides until it reaches 

the coupling device. 

11. Secure the electric cables so that they cannot be twisted or torn or drawn in by the pump.

12. Bring the cables out of the tank through a clean, smooth duct.  Do not lay cables with tight bends or in positions with risk of crushing or damage.

13. Connect the electric cables to the control panel as shown in the diagram provided in point 4.2 “Connection diagrams”.

2.6.2 Mobile installation

In mobile installation (Fig. 12) the pump is mounted on a specific base which keeps it vertically on the bottom of the tank and ensures that the 

intake is at the correct height. 

Installation procedure (Fig. 13) 

1.  Check that the pump is disconnected from the power supply panel and the impeller turns in the correct direction using the procedure described 

in point 3.2 “Checking the impeller rotation direction”. 

2.  Lower the pump onto the base using a chain or sling of suitable strength secured to the handle. Ensure that it cannot fall and/or swing.

3.  Secure the pump to the base with the screws provided.

4.  Connect the outlet to the piping using the standardised flange. Use stainless steel metal fasteners or protect the screws and nuts with a suitable 

product to prevent corrosion. A shut-off valve and a ball type check valve with full free passage should be installed using a connection pipe with 

length equal to at least 5 times the diameter of the outlet. If a hose is used, fit a flanged hose connector.  

A hose with reinforcing coil or semi-rigid hose is recommended to ensure that the free passage remains constant even at bends in the hose or 

points where it changes direction.  

Secure the hose to the union by means of a metal band clamp.

5.  Lower the pump into the tank until it rests firmly on the bottom using a chain or sling of suitable strength secured to the handle. Ensure that the 

pump cannot fall and/or swing.

6.  Secure the electric cables so that they cannot be twisted or torn or drawn in by the pump.

7.  Bring the cables out of the tank through a clean, smooth duct.  Do not lay cables with tight bends or in positions with risk of crushing or damage.

8.  Connect the electric cables to the control panel as shown in the diagram provided in point 4.2 “Connection diagrams”.
