REMKO
EWS 300
■ The hot water heater 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 ground fault circuit interrupter
switch switch 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 isolating device for all conductors
with contact opening of at least
3mm. (e.g. with a circuit breaker)
■ Details concerning the electrical
protection of the equipment are
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.
