RL 190/M - 400 V
NOTE:
The RL 190/M burner has been type- approved for intermit-
tent operation. This means they should compulsorily be
stopped at least once every 24 hours to enable the control
box to perform checks of its own efficiency at start-up. Burn-
er halts are normally provided for automatically by the boiler
load control system.
If this is not the case, it is necessary to apply in series with
IN a timer switch that turns off the burner at least once every
twenty-four hours.
These burners are also fiitted for the continuous operation,
if they are equipped with the control box LANDIS type LOK
16.250 A27 (interchangeable with the burner control box
LANDIS LAL 1.25).
Do not invert the neutral with the phase in the
electrical supply line.
