4.6.3 Connect the condensate drain
The condensate, forming during the cooling of the combustion
gases in the boiler and in the flue gas system is dumped through
the condensate tube into the storage container. By means of a
permanent neutralisation filling it is neutralised and subsequently
it is dumped into the sewer system through the safety overflow
connection (fig. 4-19).
Ɣ
Direct condensation drain pipe (not included) with constant
slope and with free inflow to the drains pipe.
Ɣ
The complete outlet must not be lockable and must discharge
the condensation and any medium leaking due to damage
(drinking water, buffer or heating water) outwards visibly (e.g.
hose to flow drain or transparent outlet pipe).
Ɣ
In order to avoid puddling, make sure that no siphon is formed
with a flexible condensate drain hose up to the waste water
pipe.
Ɣ
Check the condensate drain section for leakage.

Connection Control and Electrics
4.7.1 Instructions concerning electrical connection
All electronic control and safety devices of the ROTEX GCU
compact are connected and tested and ready for use. Modifica-
tions on the electrical installation are dangerous and prohibited.
The operator alone shall bear responsibility for any resulting
damage.
Mains connection, external temperature sensor and other op-
tional applications (e.g. storage tank temperature sensor, circu-
lation pump) still need to be connected to the boiler control panel.
4.7.2 Establishing the electrical connection
Ɣ
Check the supply voltage (
~230 V, 50 Hz
).
Ɣ
Switch the mains switch on the boiler control panel of the
ROTEX GCU compact to "OFF".
Ɣ
Switch off the automatic fuse concerned on the junction box
of the domestic insulation (provide power supply).
Ɣ
Remove the sound insulation hood (see section 4.4.3).
Ɣ
Remove the right or left side housing cover (fig. 4-20).
Ɣ
Unlock the front panel and remove from the front (fig. 4-21).
Ɣ
Turn the front panel 180° and bring into the installation
position onto the control panel casing (fig. 4-22).
Ɣ
Install the cabling into the regulation housing and establish
the electrical connections (fig. 4-23).

WARNING!
Live parts can cause an electric shock on contact and
cause fatal burns or injuries.
Ɣ
Before beginning work on live parts, disconnect
them from the power supply (switch off fuse, main
switch) and secure against unintentional restart.
Ɣ
The electrical connection should only be
performed by electrical engineers in compliance
with valid standards and guidelines as well as the
specifications of the energy supply company.
Cables for external connections are laid underneath the
right housing cover (mains connection, external tem-
perature sensor, external components and control
lines).
The left side housing cover has the cables for internal
components.

place in assembly posi-
tion.

the regulation and es-
tablish the electrical
connections.
