The fan is rated for connection to single-phase AC 220-240 V/50 Hz power mains.
The unit must be connected to power mains using durable, insulated and heat-resistant conductors (cables and wires) with minimum
cross section not less than 0.5 mm
2 (the given wire sections are for reference only).
The actual conductor cross-section selection must be based on its type, the maximum permissible heating, insulation, length and
installation method (in the air, pipes or inside walls).
The fan must be grounded. The fan must be connected to the terminal block installed in the fan terminal box in accordance with the
wiring diagram and terminal designation according to the corresponding diagrams.
The external lead-in (220-240 V/50 Hz) must be equipped with a circuit breaker built into the stationary wiring to disconnect all the mains
phases. The fans must be connected to power mains through a circuit breaker with at least 3 mm gap between contacts on all poles.
The S1 external circuit breaker location must ensure free access for quick shutdown of the unit.
The protection operation current should be selected depending on the fan current consumption.
The recommended rated current of the automatic circuit breaker is 1.6 А.
The KAM, KAM Eco, KAM EcoDuo fans have a built-in thermostat relay, which closes the fan power circuit when the set temperature of
the hot air in the fireplace is reached (the fan automatically turns on and the warm air enters the room).
As the temperature drops below the set value the fan switches automatically off.
