6.1 Maintenance
The product is maintenance-free during normal operation. For
cleaning, use a dry and dust-free cloth.
6.2 Maintaining the pressure tank
Check the precharge pressure annually.
The pressure tanks are supplied from factory with a precharge
pressure. See tank nameplate.
Do not use a tank with signs of damage, such as dents, leakage or
corrosion.
6.2.1 Adjusting the precharge pressure
CAUTION
Pressurised system
Minor or moderate personal injury
‐ Before starting work on the product, make sure there is
no system pressure on the tank.
‐ Disconnect pumps or switch off the power supply.
1. Make sure that there is no water pressure in the tank. Switch
off the pump and open a tap, or close the isolating valves and
drain the pump.
2. Use a suitable pressure gauge to check the precharge
pressure.
3. Release or add compressed air to make the precharge
pressure equal to the recommended precharge pressure.
4. If water escapes during the precharge-pressure check, the
membrane is defective.
