Operation Of The Pressuremate Electronic Pressure Switch - Pentair Flotec AUTOJET 1000 Manual De Uso

DANGER - ELECTRIC SHOCK RISK
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.
PENTAIR 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.
CHAPTER 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.
DANGER - ELECTRIC SHOCK RISK
The electronic PRESSUREMATE pressure switch (including the safety cables) can be opened or
replaced only by qualified personnel.
