2.3 Assembly and Electrical Connection

The heater should be only removed from its packaging near to its place of final assembly. Small
cracks or chips in the heater core bricks have no influence on the operation of the heater.

2.3.1 Opening the heater

1. Take out the 2 fixing screws at the top right and
left of the operating plate.
2. Take out the 4 fixing screws on the front cover
panel and remove the cover panel forwards.
Remove the equalising fascia plates on the rear
of the cover panel.
3. Push the operating panel upwards, then outwards
and remove it sideways.
4. Take out the 2 fan compartment fixing screws at
the bottom of the inside panel.
Remove the fan wiring from terminals 12 and N,
and earth on the connecting panel.
Remove the connecting wires of the room
temperature sensor B2 from the charge and
discharge control B1 (bottom right, near the fan
compartment) (take off the cable with 2 flat
spade connectors 2.8 – TF1 and TF2).
Unscrew the thermostat F4 from the inside panel.
If a day acting element (DAE) is installed, remove
the switching thermostat F2.1 from the inside
panel and take off the DAE connecting wires
from the control panel (remove wires to LH, N
and earth).
Pull out the fan compartment together with the
base board from the front of the heater.
Note: Make sure that no connecting wires are damaged, removed or taken out of the
heater. Run the wires accordingly, so that this does not happen.
