5.5 Connecting water to the tank

The assembly, connection and usage instructions of the hot water heater (boiler), as well as ÖNORM
(Austrian standard) B2531 T1 or DIN (German standard) 1988, must be observed at all times.
Pressure-resistant connection
Any warranty is voided if inappropriate or defective tank connection fittings are used and/or if the stated
operating pressure is exceeded.To make the water connection, it is mandatory to use a type-approved
diaphragm safety valve or a diaphragm safety valve combination – connection fitting for pressureresistant
tanks! A safety valve combination consists of shutoff valve, test valve, return flow valve, drain valve and
safety valve with expansion water discharge. It is installed between the cold water supply line and the cold
water inlet (blue) of the tank in the sequence shown below.

5.6 Electrical connection

The installation of the heating element and commissioning must be carried out by a skilled
person who assumes the responsibility for the proper execution and configuration in his/
her capacity as a professional. As a basic rule, the electrical connection should be made
as indicated on the enclosed, type-specific wiring diagram! Make sure the supply voltage
is correct! All accessible metal parts of the tank must be covered by the safety/protection
measure.
The cover must not be insulated.
An allpole disconnector with 3 mm contact gap width must be integrated in the power supply line. An
automatic circuit-breaker may also be used as the disconnecting device. The connecting cable must be
introduced into the connection space of the fitted heater through the attachment bolting. A cable grip
(strain relief device) must be used for protection against pulling and twisting.
The connection with the power grid must be implemented in conformity with the applicable national
regulations and standards, the relevant connecting requirements of the local power company
and waterworks, as well as the standards of the Mounting and Operating Instructions, and must be
performed exclusively by a licensed electrician. The stipulated protective measures must be executed
carefully, so that no other power-supplied devices are affected thereby in the event of a malfunction
or failure of the hot water tank's power supply (e.g. freezer, rooms used for medical purposes, units for
intensive care, etc.).
