Checking the pressure in the tank (A10)
To ensure that the appliance operates correctly, the pressure in the
tank (A10) must be checked at regular intervals (3-4 times a year); it
must be 1.5 bar. To check the pressure, unscrew the valve cap (A9 b)
on the tank (A10) and check the pressure by connecting an air pump
with pressure gauge to the valve (A9) (fig. 11). If the pressure is less
than 1.5 bar, restore it to that value.
Insufficient air pressure causes the appliance to malfunction and leads
to wear of the rubber diaphragm in the tank (A10). Any damage to
the appliance caused by incorrect pressure in the tank (A10) is not
covered by the warranty.
10 STORAGE
Warning - danger! The system is pressurised!
Before any maintenance procedure and/or during troubleshooting, disconnect
the power cable (A8) from the socket.
Check that the connection hoses or the appliance's tank (A10) are not still
pressurised. To ensure this, turn on a user (water supply tap) and drain all
the water from the system. All storage procedures can then be carried out.
It is essential to protect the appliance from frost, and in case of
temperatures of +5°C or below it must be uninstalled and stored in
a dry place, protected from frost. After disconnecting the suction and
delivery hoses, unscrew the drain plug (A3) and tilt the appliance to
drain out all the water in the tank (A10). To empty the pump body (A4)
turn the appliance upside down to drain the water from the delivery
fitting (A2).
