Ch. 6 Operation of the PRESSUREMATE electronic pressure switch (Fig. 1, n. 12)
A panel is mounted on the front of the device which displays all the operating phases of the system by means of pilot
lights: green pilot light Power on, yellow pilot light Pump on, red pilot light Failure. At the moment of connection to
the electrical mains, the green light turns on together with the yellow light indicating the start-up of the pump (fig.
3/A) which remains in operation for a few seconds in order to allow the system to build up pressure. If this time is not
sufficient, the red Failure light will turn on (fig. 3/C); in this case keep the red Restart (rearm) button pressed and wait
with a service open for the red pilot light to turn off. After the service is closed, the device stops the pump and goes
into standby mode, the green pilot light lit, ready to carry out in complete autonomy all the subsequent command and
control operations (fig. 3/B).
On opening a service, the device starts the pump which remains in operation for as long as the service itself is open (fig.
3/A). After the service has been closed, the device restores maximum pressure to the system, then stops the pump and
returns to the standby mode (fig. 3/B). In the event of water shortage during aspiration, the device recognises the failure
which it signals with the red Failure light, and stops the pump (fig. 3/C) protecting it from dry running. Once the causes
of a blockage have been removed, it is sufficient to press the red Restart (rearm) button to restore normal operation. In
the case of a temporary power outage the device will automatically restart as soon as the electricity returns.
The electronic PRESSUREMATE pressure switch (including the safety
cables) can be opened or replaced only by qualified personnel.

Make sure that the pump and the electric connections are protected from possible inundation.
Before using the pump, always inspect it visually (especially power cable and plug).
Do not use the pump if it is damaged.
If the pump is damaged, have it inspected by the specialised assistance service only.
Do not transport the pump using the cable or use the cable to remove the plug from the socket. Protect the plug and
the power cable from heat, oil or sharp edges.

The power cable must be replaced by qualified personnel only.
Start-up
Before starting the pump, fill the suction pipe (2) and the pump body (8) using the filling cap (9). Close the cap after
verifying that there are no leaks. Open the closing devices on the delivery pipe (i.e. the water cock) so that air can be
released from the suction cycle.
Insert the pump plug into a 230 V alternate current socket. The pump starts immediately.
FLOTEC AUTOJET series automatic electropumps are self-priming. Therefore, they can be started without having to fill
the inlet pipe with water. However, it is necessary to fill the pump body. The priming operation requires a few minutes.
It may also be necessary to fill the pump body with water several times, according to the length and diameter of the
suction pipe. If the electropump is not used for a long period of time, it is necessary to repeat all the operations described
above before starting the pump.
