4.3.1 Hot water storage tanks

DANGER: RISK OF ELECTROCUTION

Touching live parts can result in an electric shock and lead

to potentially fatal injuries and burns.

▪ If there is an electric immersion heater or an external

current anode installed in the hot water storage tank,

these components must be isolated from the power sup-

ply before starting work (e.g. fuse, main switch switched

off and secured against inadvertent switching on again).

1 Open all water outlets to vent the system.

2 Open the cold water pipe valve.

3 Check the system for leaks.

4 When the system is vented, close all water outlets.
