Troubleshooting - Master B 18 EPR Manual De Instrucciones Para El Uso Y Mantenimiento

WARNING !!!: The heater is fitted with a phase
control relay which monitors correct phases con-
nection. The relay prevents the ventilator engine
from rotating in the wrong direction. If the signal
light no 11 remains lit for more than 2 seconds, it
means that a phase is missing or phases are con-
nected in wrong order. In such case, please check
device phase connection or change phase order in
the power supply socket.
Make sure the power supply cable has not been damaged. If the
supply cord is damaged, it must be replaced by the manufac-
turer, its service agent or similarly qualified persons in order to
avoid a hazard. Moreover, check if the technical parameters of
power supply source comply with the requirements specified on
the rating plate. Place the appliance in its upright position. Make
sure the switch is in its "0" position shown in Fig. 3. Connect the
heater to the power supply source. Turn the switch and leave it
for 5 seconds in the positions as follows:
► Fan only: Fig. 3;
► 1st degree of heating: Fig. 3, and
► 2nd degree of heating: Fig. 3.
