3.5 Electrical connections

Connection to the electrical grid
B
The unit's electrical safety is only guaranteed when correctly connected to an
efficient earthing system executed according to current safety standards. Have
the efficiency and suitability of the earthing system checked by professionally
qualified personnel. The manufacturer is not responsible for any damage
caused by failure to earth the system. Also make sure that the electrical system
is adequate for the maximum power absorbed by the unit, as specified on the
boiler dataplate.
The boiler is prewired and provided with a Y-cable and plug for connection to the elec-
tricity line. The connections to the grid must be made with a permanent connection and
equipped with a bipolar switch whose contacts have a minimum opening of at least 3
mm, interposing fuses of max. 3A between the boiler and the line. It is important to re-
spect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green
wire) in making connections to the electrical line. During installation or when changing
the power cable, the earth wire must be left 2 cm longer than the others.
B
The user must never change the unit's power cable. If the cable gets damaged,
switch off the unit and have it changed solely by professionally qualified person-
nel. If changing the electric power cable, use solely "HAR H05 VV-F" 3x0.75
mm2 cable with a maximum outside diameter of 8 mm.
Room thermostat (optional)
B
IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-FREE
CONTACTS. CONNECTING 230 V TO THE ROOM THERMOSTAT TERMI-
NALS WILL PERMANENTLY DAMAGE THE ELECTRONIC BOARD.
When connecting time controls or a timer, do not take the power supply for
these devices from their breaking contacts Their power supply must be by
means of direct connection from the mains or with batteries, depending on the
kind of device.
Accessing the electrical terminal block
Undo the two screws "A" located on the top part of the control panel and remove the
cover.

ATLAS D ECO COND UNIT

3.6 Connection to the flue

The unit must be connected to a flue designed and built in compliance with the current
regulations. The pipe between the boiler and flue must be made from material suitable
for the purpose, i.e. heat and corrosion resistant. Ensure the seal at the joints.

3.7 Condensate drain connection

The unit's condensate drain must be connected to a suitable disposal system. Comply
with the specific local and national regulations on discharging condensate water into the
waste water disposal system. For boilers not using exclusively low-sulphur gas oil (S
content<50 ppm) make sure to provide for a suitable condensate neutralisation device.
Connect the condensate drain pipe located at the back of the boiler (ref. A - fig. 26) to
the neutralisation device connected to the waste water system. The condensate dis-
charge pipes must be acidproof and installed sloping at least 3° towards the drain, with-
out any constrictions and obstructions.
B
IMPORTANT. Fill the trap with water before starting the unit.
ATTENTION: The unit must never be operated with the trap empty!
Periodically check the water in the trap.
