DAB Esybox Serie Instructions Pour L'installation Et L'entretien page 51

5.2. Transport
Avoid subjecting the product to needless impacts and collisions.
6. INSTALLATION
The pumps may contain small amounts of residual water from testing.
•
We recommend washing them briefly with clean water before final installation.
•
The electric pump must be installed in a well-ventilated place and with an ambient temperature not higher than that indicated in
•
the technical specifications of each product.
A solid anchoring of the pump to the base supports the absorption of any vibrations created by the operation of the pump.
•
Do not allow the metal pipes to transmit excessive stress to the pump ports, so as not to create deformation or breakage.
•
It is always a good idea to place the pump as close as possible to the liquid to be pumped.
•
The pump must be installed under conditions appropriate to the specificities of the product.
•
The system can suck in water whose level does not exceed a depth of 8 m (height between the water level and the suction port of the pump)
•
It is recommended to carry out the installation according to the instructions in the manual in accordance with the laws, directives
•
and regulations in force at the site of use and depending on the application.
The pump is not self-priming. It is suitable for suction from tanks or connected to the aqueduct in relaunch where it is possible
•
according to local regulations.
The product in question contains an inverter inside which there are direct voltages and currents with high-frequency components.
The residual current circuit breaker protecting the system must be correctly sized according to the characteristics indicated in Table 3.
For inverters with three-phase power supply, we recommend a residual current circuit breaker that is also protected against untimely trips.
Carefully follow the recommendations in this chapter to achieve proper electrical, plumbing, and mechanical installation. Before you set
out on any installation, make sure that you have turned off power to the power line. Strictly observe the power supply values indicated
on the electrical rating plate.
6.1. Recommended predispositions
Shut-off valves are to be mounted upstream and downstream of the pump in order to avoid having to empty the system in case of
maintenance to the pump. For wall mounting, follow the instructions below:
This product is already designed to be installed suspended on the wall using a DAB accessory kit to be purchased separately.

6.2. Plumbing and piping connection
Make the inlet connection to the system through the suction port indicated in Fig. 1, then remove the cap with the help of an accessory
tool or a screwdriver. Make the connection to the exit of the system through the discharge port indicated in Fig. 1, then remove the cap
with the help of an accessory tool or a screwdriver.
All hydraulic connections of the system to the system to which it can be connected are of the 1" female thread type.
If you intend to connect the product to the plant with fittings that have a diameter larger than the normal 1" pipe (for
example the ring nut in the case of fittings in 3 pieces), make sure that the 1" Gas male thread of the coupling protrudes
at least 25 mm from the above diameter (Fig. 6).
With reference to its position with respect to the water to be pumped, the installation of the system may be defined "above head" or
"below head". In particular the installation is defined "above head" when the pump is placed at a level higher than the water to be pumped
(e.g. pump on the surface and water in a well); vice versa it is "below head" when the pump is placed at a level lower than the water to
be pumped (e.g. overhead cistern and pump below). See chapter 16 SPECIFIC CONFIGURATIONS.
6.3. Electrical connection
Caution: Always observe the safety regulations!
A device must be provided in the power supply network that ensures complete disconnection under the conditions of
overvoltage category III. When the switch is in the open position, the separation distance of each contact must comply
with the instructions in the table below:
Power Supply Range (V)
Make sure that the mains voltage corresponds to the CE marking voltage (technical plate) of the product.
