Functionning Of The Electronic Pump Control System; General Information - SPIDO K 800 Mode D'emploi

Please inspect the pump visually prior to each use. This applies in particular to the mains connection line and the
mains plug. Make sure that all screws are firmly tightened, and verify the perfect condition of all connections. A
damaged pump must not be used. In any case of damage, the pump has to be inspected by qualified service
staff.
Prior to the first time the pump is put into operation, the pump housing (8) has to be fully vented. To do so, please
fill the pump housing (8) through the filling opening (9) completely with water. Please check to make sure that no
leakage occurs. Subsequently, close the filling opening airtight again. It is highly recommended to vent the suction
line (2) as well, i.e. to fill it with water. It is true that the electrical pumps SPIDO are self
priming and can be put into operation by filling only the pump housing with water. In this case, however, the pump
will require some time before it will have sucked in the liquid to be pumped and proceed to the actual discharging
function. In addition, this way of proceeding may require the pump to be filled several times. This depends on the
length and diameter of the suction line. After filling, please open any shutting device (7) in the pressure line, for
instance a water tap, to enable the air to escape during sucking in.
Plug the mains plug into a 230V AC socket. The pump will start running immediately. As soon as the liquid is
being discharged evenly and without air mixture, the system is ready for operation. You may then close the shut-
off vlave in the pressure line again. The pump will cut out upon reaching the cut-out pressure.
In the course of the first put into operation it may be possible under certain circumstances that the electronic
pump control will switch the pump off and the red „Error" warning indicator will light up. As a rule, this is caused by
the fact that the amount of air within the system was too large at the first intake cycle, thereby causing the anti
dry-running feature to trigger. In this case, please press the "Start pump" button on the electronic pump control to
put the unit to operation again (please cp. „Functioning of the electronic pump control" section). This step may
have to be repeated several times until the first intake cycle is completed and the system is vented. Prior to each
pressing of the start button, please make sure that switching off was not the result of some other cause which
must be eliminated prior to each new start.
If the pump was out of operation for some extended period of time, the steps described above have to be
repeated for a renewed putting into operation.
The electrical pumps SPIDO are equipped with an integrated thermal motor protection
feature. In the case of overload, the motor will switch off independently and on again after cooling down. For
possible causes and their elimination, please refer to the "Maintenance and troubleshooting" section.
. Functioning of the electronic pump control system
.1.

General information

The electronic pump control feature acts as a function of the pressure and the water flow rate. On the one side, it
will cause the automatic cutting-in or cutting-out of the pump when the water tap or any other consumer
component is opened or closed. On the other side, the electronic pump control will trigger the automatic cut-out
feature of the pump in the case of dry running or absence of water, which means if the volume of the water being
discharged is insufficient or if no water is being discharged at all. This will prevent damage to the pump caused by
overheating.
.2. Functioning
Opening a water tap or any other consuming component will lead to a drop of the pressure inside the pipe
system. As soon as the preset cut-in pressure is reached, the electronic pump control will start the pump.
Following the closing of the consuming component, the pump will continue to run until the pressure in the system
stops to raise, subsequently it will cut the pump out. The pipe system will then be subject to the max. attainable
pressure of the pump.
.3. Cutting out in the case of dry running or absence of water
In the case of dry-running or the absence of water, the electronic pump control will cut the pump out. In addition,
the red "Error" warning indicator will light up. This protection feature will prevent another automatic start-up of the
pump. To resume operation, the "Start Pump" key of the electronic pump control has to be depressed. Before
doing so, please make sure to eliminate the cause of the dry running.
.4. Setting the pump pressure
Changes to the preset switch-on pressure must only be performed by qualified staff.
The switch-on pressure is preset to 1.5 bar. Experience has shown that this value is ideally suited for most
installations. Should any modification of this setting be required, please contact a qualified provider of plumber or
electrician services.
In this context, please note that a modification of this kind will only affect the switch-on pressure of the pump, but
will not cause any pressure increase inside the pipe system.
