3.4.2 Mobile installation
In mobile installation (Fig. 15) 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 (See APPENDIX 2 page 131)
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 the manual.
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.
5. 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.
6. 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.
7. Secure the electric cables so that they cannot be twisted or torn or drawn in by the pump.
8. 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.
9. Connect the electric cables to the control panel.
3.4.3 Vertical installation in dry chamber
For vertical installation in a dry chamber (Fig. 16), the pump is supplied, on request, with intake flange designed for fixing to a curved base (KBC).
Installation procedure (See APPENDIX 3 page 132)
1. Construct two supports on the bottom of the tank in a material which will support the weight of the pump and the stresses which it generates
(cement, concrete, brickwork, etc.), in order to set the intake port at the correct height. The recommended dimensions are provided in the tech-
nical information sheet.
2. Check that the pump is disconnected from the power supply system and that the impeller turns in the correct direction using the procedure
described in the manual.
3. Place the pump on the base and secure it with the fixing screws.
4. Connect the flanged elbow to the pump intake port with the fixing screws. If necessary, lay the pump on its side and fix it in position to prevent
accidental movements.
5. Secure a chain or sling of suitable strength to the pump handle and lower the pump into the tank, placing the base on the supports in the bottom.
6. Mark the positions of the mounting holes.
7. Make holes of suitable diameter for the base fixing slots.
8. Fix the base firmly to the two supports using chemical or expansion plugs. Use stainless steel metal fasteners or protect the screws and nuts
with a suitable product to prevent corrosion.
9. Connect the intake pipeline to the flanged elbow;
