Electrical Installation - DAB ESYBOX DIVER Instructions Pour L'installation Et La Maintenance

The maximum submersibility of the pump depends on the length of the power cable: 12m (39.4 ft) in the case of a cable 15m (49.2 ft) long; 7m
(23 ft) in the case of a cable 10m (32.8 ft) long. Check the details on the technical data plate, as shown in figure 4.
In order to always guarantee a good water flow, it is advisable to enter a Setpoint pressure value to compensate for the difference in height
between the service taps and the pump (see figure 7).
To facilitate installation in the tank, it is possible to remove the power cable and/or pass it through another passage hole.
To remove it, follow the instructions on the product's quick guide. The electrical cable has a quick connection.
Have this operation carried out by qualified personnel. Check the earth connection before commissioning the product.
The pump has:
An air vent valve (see figure 8). This valve allows the pump to prime in a very short time. If the water level is lower than the valve level,
•
some water may escape from the vent valve.
A small spring and diaphragm expansion tank. This limits the number of pump restarts and compensates for small system losses. The
•
tank protects the pump in case of water hammer. The tank does not require any refilling or maintenance.
An overpressure valve, which prevents water hammer. In case of ice in the delivery pipe with a submerged pump, this valve protects
•
the pump from breakage.
Installation in a well.
Install the pump so that the pump suction is at least 1 m (3.28ft) above the bottom of the well to prevent the intake of sand and impurities. Use
rigid metal pipes to hang the pump and secure the pipes with brackets at the top of the well.
Installation in a tank
The minimum dimensions for the pump passage in the collecting tank are 180x185 mm (7.09x7.28 in).
Hold the pump slightly up from the bottom so as to avoid possible noises/vibrations transmitted to the tank.
The pump will make noise if it is placed on the bottom of the tank.
To avoid obstruction of the suction passages, it is recommended to check periodically that no dirt has accumulated in the
collection trap (leaves, sand, etc.).

Electrical Installation

It is recommended to carry out installation as indicated in the manual, in compliance with the laws, directives and standards in force in the place
of use and depending on the application.
Leakage current to earth < 5mA.
Do not remove the label on the power cable of the ESYBOX DIVER because it will be useful in case of future changes and
configurations of the system.
The ESYBOX DIVER pump contains an inverter inside which there are continuous voltages and currents with high-frequency components.
For this type of equipment the possible fault currents to earth can be:
alternating current
•
unipolar pulsed current
•
currents with high-frequency components
•
