PELLET STOKER KMP PX50
ARITERM SWEDEN AB
Installation Instructions - 2007.12.14 - 5/16
Electric installation
All electric connections on the stoker and
screw feeder have fast action connectors
as below
1. To boiler temperature sensor
2. To screw feeder (230V)
3. Supply (230V)
There is also a connector on the feeder motor (same as number 3 in Fig. 2). The yel-
low cover has to be removed before the cords can be disconnected from the stoker.
The mains power cord must be installed by an authorized electrician.
A safety cut-out thermostat on the boiler must be used.
NOTE!
Old manual reset cut-out thermostats can cause problems.
These shall be removed and replaced by new.
All connections are to be made with the enclosed cables and connectors.
NOTE! The stoker has to be connected to the mains on a manual reset cut-out
thermostat on the boiler.
The bulb of the cut-out thermostat has to be immersed in the boiler water or other-
wise located on the boiler where a quick action is guaranteed in case of overheating.
If there is no thermostat on the boiler, an external one has to be installed (optional
extra).
NOTE!
If a non-standard feeder motor of more than 300 watts is being used, an
intermediate relay has to be used.
