6.6 Electrical installation
Electrical installation should be carried out in accordance with the wir-
ing diagram. In the vicinity of hot parts (flue gas fan, flue pipe), cables
must be routed in steel pipes for temperature protection and appro-
priate clearances.
The cable entries for the motors and equipment should be dust-proof
and unstressed.
Positioning of the programming module and control panel
The programming module should be installed by the electrical com-
pany responsible for installation in a place that is easily accessible for
operation. Optimal positioning of the control panel can minimise cable
lengths and therefore reduce costs. The location of the programming
module and control panel should be selected so that the negative
influence caused by thermal radiation (boiler front panel, boiler back
panel with flue gas collector and flue gas fan, as well as flue pipe) and
exposure to dust during cleaning is minimised.
The ambient temperature of the control panel (approx. 10 cm away
from the control panel) when operating the system must not exceed
40 °C. In case of doubt, the control panel should preferably be located
outside the boiler room near to the boiler room door.
Note
The regulations of the local power supply utility must be observed.
6.7 Safety equipment
Expansion
In the case of sealed expansion, the pre-charge pressure of the expan-
sion vessel should be equal to the max. system height plus 0.2 bar.
Extinguishing facilities
A water extinguishing facility is required on the supply screw conveyor.
This facility is used in the event of a fault (e.g. power failure) to safely
prevent burn-back. For safety reasons and in order to avoid damage
caused by flooding, it is not advisable to connect the extinguishing
facility directly to the water mains.
This extinguishing facility is equipped with an extinguishing water con-
tainer 25 l with float switch and an adjustable Danfoss extinguishing
valve. In accordance with TRVB 118, the container should be equipped
with fill level monitoring. The PYROT rotation combustion system
automatically switches off in case of a water shortage. In the case of
excessive temperature, the supply screw conveyor is safely flooded
but to a limited extent.
