Drainage pipes
The diameter of the pipes that drain the water should be equal to or greater than
the diameter of the pump outlet. The pipes/hoses must not hold back pressure and
must be checked for watertightness.
Failure to comply with the above conditions may result in damage to the pump and
the installation!
Electrical connections
Always make sure that all connections and connectors between the mains (or other
voltage source) and the hydrophore unit are correct and undamaged. This also ap-
plies to the cables and wires from and in the hydrophore unit. For the correct con-
nection, see the wiring diagram (fig. 3). The appliance must be connected to an
earthed power socket. The security for the installation must be equipped with an
earth leakage switch of 30 mA. The power cable must comply with EEC standards
or be type H07 RN-F (VDE0620). Failure to comply with the above conditions may
result in damage to the pump and the entire system and creates a risk of electric
shock!
Checks before start-up
Before starting up the pump for the first time, make sure that:
 voltage and frequency of the power source correspond to the specifications on
the hydrophore unit nameplate
 the pump shaft rotates smoothly and freely
 the pump body is completely filled with water; unscrew the relevant power plug
(on top of the pump) and fill the pump.
THE PUMP MUST NEVER RUN DRY!
See also the installation diagrams. Failure to comply with the above conditions may
result in damage to the pump and the entire system!
Starting
Open all flow valves in the suction and discharge pipes. Turn on the power and the
pump will start automatically. While doing this, the tap point should be open to al-
low any air in the system to escape. Afterwards, close the tap and the unit will
switch itself off when the maximum pump pressure is reached. If the hydrophore
unit does not work, does not build up pressure or does not switch off, first try to
find the cause of the fault by consulting the fault indicator.
Maintenance
Regularly check that the pressure in the pressure vessel is sufficient as follows:
- Remove the plug from the socket
- Open the tap and drain all the water from the system
- Unscrew the black cap on the back of the pressure vessel
- Check the pressure in the boiler with a tire pressure gauge: the pressure
should be 1.7 bar, if not 1.7 bar, correct the pressure.
- Put all parts back in the right place
Furthermore, the EUROM hydrophore unit requires no specific maintenance. Never-
theless, we recommend that you drain the pump if the pump will not be used for a
