DANGER: RISK OF ELECTROCUTION
During the filling process, water can escape from any leaking point and can cause an
electrical shock if it comes into contact with live parts.
▪
Before the filling process, de-energise the unit.
▪
After the first filling and before switching on the unit with the mains switch, check
whether all electric parts and connection points are dry.
1 Connect a hose with a non-return valve (1/2") and an external manometer
(field supply) to a water tap and the fill and drain valve. Secure the hose
against slipping off.
