Starting - DAB JET Série Mode D'emploi

5. STARTING

To start the set correctly, perform the procedure below following the sequence indicated:
5.1
Check that the moving parts turn freely. To do this, remove the fan cover and, if necessary, the fan; then turn the shaft with a suitable tool
(screw driver, offset adjustable spanner, etc.). (fig. 5)
If it is blocked, tap lightly with a hammer on the end of the tool, then try to turn the shaft again.
5.2
Prime the set as follows:
a) Slowly pour in clean water through a sleeve of the suction manifold, keeping open the filling cap (ref.25) of one of the electropumps to
allow the air inside to get out, until the manifold is filled (fig.6/I).
b) Slowly pour in clean water through a sleeve of the delivery manifold (for example, the expansion vessel connecting sleeve.), until water
comes out of the pump filling hole from which the tap has previously been removed. (fig.6/II)
5.3
Fit the expansion vessels on the special sleeves of the delivery manifold.
It is possible to increase the storage capacity by connecting other tanks to "T" couplings, fitted beforehand between the sleeves and the
expansion vessels.
5.4 Sets with one or three three-phase pumps:
Open the electric panel and check that the overload protection switches of the electropumps have been calibrated according to the
following value:
rated current In (shown on the pump data plate) increased by 10%.
Sets with one or three single-phase pumps:
Single-phase electropumps are already self-protected. The electric panel contains overload protection switches that do not need
regulating.
Sets with two single-phase or three-phase pumps:
See the enclosed instructions booklet of the E-BOX electric panel (Imax regulating trimmer)
For other data on the electric connection, supply and starting of the set, always see the enclosed electric panel instructions booklet.
5.5
Start each pump manually for a few moments using the AUT-0-MAN selector (or with the MAN button in the case of sets of two pumps) and
check that, when viewed from the fan side, the motor is turning in a clockwise direction.
If not, exchange any two leads of the power supply cable on the terminal board.
The electric panels of the sets with two or more pumps manage the change-over of the starting of the respective pumps, so as
obtain uniform use.
Perform the following operation without switching on the power to the panel.
Perform the following operation without switching on the power to the panel.
Perform the following operation without switching on the power to the panel.
Check that the pumps are turning in the correct direction (Only for three-phase motors).
