WATER HEATING REQUIREMENTS
It is a legal requirement that water be heated on a
regular basis to kill Legionella bacteria that can lead to
Legionnaires disease. The frequency this temperature
must be reached varies, and is explained in the table
below.
CONNECTIONS
Electrical Connections:
The electrical element will be required to be directly
connected to a 240V AC 50Hz mains power supply.
Flexible conduit is required to enclose any exposed
electrical cables to the storage unit.
AUXILIARY HEATING
Table 3 Minimum Heat Requirements
TYPE OF THERMANN SYSTEM
INSTALLED
MINIMUM HEAT
REQUIREMENTS
Glass-lined Bottom element
electric boosted system
Once per week for 60°C for 32
minutes
ALL ELECTRICAL CONNECTIONS MUST BE
COMPLETED BY AN AUTHORISED AND LICENSED
PERSON.
Thermostat Setting:
The thermostat should be set to 60°C or above as per
AS/NZS 3498.
To adjust the temperature setting:
• Disconnect the electrical power supply to the tank
• Remove the element cover
• Using a screwdriver, rotate the thermostat dial to the
desired temperature
When the electric element is activated it will heat up all
the water above the element to 60°C (or the thermostat
setting). This heating can take as long as 3-4 hours if
the tank is cold.
Note:
Thermann recommends that the electric booster
is left on, or controlled by a suitable timer.
Water Connection:
Unions should be used on both the hot and cold water
supply lines for connections and the water lines should
be purged to remove all debris and air.
To ensure optimal operation and to maintain the
integrity of the Thermann EHW tank, ensure that each
of the following processes is carried out prior to leaving
the site.
CHECKLIST PRIOR TO LEAVING
INSTALLATION SITE
• EHW tank check: check all connections for leaks
and that all components are installed as per this
manual.
• Take photos of all system components for warranty
purposes. This should include photos of the
plumbing lines to and from the tank.
