ETS 300
■ The hot water tank must be filled
with water before being put into
service.
■ A mains connection must be installed
and appropriately fused according
to the circuit diagram affixed
in the terminal box for the unit.
■ A residual current circuit breaker with
a tripping current of I∆N ≤ 30mA
must be located upstream from
the supply circuit.
■ All cables and wires to and from
the unit must be fixed in place.
■ The electrical installation must
have an upstream-connected
isolating device for all poles, with
a contact opening of at least 3mm.
(e.g. in the form of a circuit breaker)
■ The electrical protection
of the equipment should
be implemented according
to the information provided
in the technical data.
! ATTENTION
All electrical installation work
is to be performed by specialist
companies. Disconnect the power
supply
when connecting
the electrical terminals.
Before commissioning
Before being placed into service, the
register must be flushed in order to
remove any soiling (e.g. scale) from the
heating circuit.
The smooth pipe heat exchanger
(register) must be rinsed out properly
before the initial installation is carried
out (we also recommend the installation
of a dirt filter). If the smooth pipe
heat exchanger is not used while
operating the tank (e.g. only electric
heating), it must be filled completely
with an appropriate glycol mixture in
order to prevent corrosion from the
accumulating condensation water. The
filled glycol heat exchanger may not
be closed on both sides after filling
(temperature-based pressure expansion).
Before the warm water tank is connected
to the mains electricity supply and put
into service for the first time, it is vital
that it is filled with water.
During initial filling, the discharge valve
must be open. The storage tank is
fully filled, when water which is free of
bubbles starts to run out of the discharge
pipe of the valve.
