3.5 Installation with DAC coupling device (TYPE P) (Fig. 12 page 70)
With this type of installation, the pump can be removed from and replaced in the tank quickly without any work on the system.
3.5.1 System components (Fig. 13 page 70):
1a. DAC V coupling device (vertical outlet)
1b. DAC H coupling device (horizontal outlet)
2. Coupling flange or hook (changes depending on pump model)
3. Screws
4. Pipe guides (not included)
5. Spacer bracket
3.5.2 Installation procedure (Fig. 14A page 70)
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. Fix the flange to the pump's outlet port with the screws provided.For models with hooks, fix the hook to the pump body using the screws pro-
vided.
3. Place the coupling device on the bottom of the tank and mark the position of the holes required to fix it.
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
EN
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
warning
the pipe guides (Fig. 14B page 70).
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.
During the installation of ATEX version electric pumps, be very careful when lifting or lowering the electric pump into the well, as the
metal parts can generate sparks if they rub against each other.
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. Take off the heat-shrink sheath that protects the end of the cable, following the instructions provided in paragraph 2.2.
14. Connect the electric cables to the control panel as shown in the diagram provided in point 4.2 "Connection diagrams".
3.6 Mobile installation (TYPE S) (Fig. 15 page 71)
In mobile installation (TYPE S), 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.
3.6.1 Installation procedure (Fig. 16 page 71)
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. Take off the heat-shrink sheath that protects the end of the cable, following the instructions provided in paragraph 2.2.
9. Connect the electric cables to the control panel as shown in the diagram provided in point 4.2 "Connection diagrams".
3.7 Vertical installation in dry chamber (TYPE T) (Fig. 17 page 72)
For vertical installation in a dry chamber, the pump is supplied, on request, with intake flange designed for fixing to a curved base (KBC).
3.7.1 Installation procedure (Fig. 18 page 72):
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
technical 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 point 3.2 "Checking the impeller rotation direction".
