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.
Check that the pumps are turning in the correct direction (Only for three-phase motors).
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.
5.6.
CHECKING CALIBRATION OF THE PUMP CONTROL PRESSURE SWITCHES
(only for sets with three pumps*):
Proceed as follows:
a)
Switch off the electric power supply, turning the main switch to “0” and open the panel.
b)
Remove the automatic inverter SZ3 and connect the connectors XC1 and XC2 together.
c)
Close the electric panel and switch the power on again, turning the main switch to “1”.
d)
Turn the AUT-0-MAN selector of pump 1 to AUT and the selectors of pumps 2 and 3 to 0.
e)
Partly turn on the flow at delivery (*) and wait for pressure switch No. 1 to give the command to start pump No. 1.
On the pressure gauge, check that that the pump starting pressure is as required..
f)
Turn off the flow, checking that the pump stops at the required pressure (**).
g)
Turn the AUT-0-MAN selector of pump 2 to AUT and the selectors of pumps 1 and 3 to 0.
h)
Partly turn on the flow at delivery (*) and wait for pressure switch No. 2 to give the command to start pump No. 2.
On the pressure gauge, check that that the pump starting pressure is as required.
i)
Turn off the flow, checking that the pump stops at the required pressure (**).
l)
Turn the AUT-0-MAN selector of pump 3 to AUT and the selectors of pumps 1 and 2 to 0.
m)
Partly turn on the flow at delivery (*) and wait for pressure switch No. 3 to give the command to start pump No. 3.
On the pressure gauge, check that that the pump starting pressure is as required.
n)
Turn off the flow, checking that the pump stops at the required pressure (**).
o)
-
Switch off the electric power supply, turning the main switch to “0”, open the electric
panel, disconnect the connectors XC1 and XC2 and reconnect them to the automatic
inverter SZ3.
-
Close the electric panel and switch the power on again, turning the main switch to 1
(ON).
p)
Check that all the AUT-0-MAN selectors of the pumps have been turned back to “AUT”.
q)
Completely reopen all the interception valves that may have been choked.
