Never repair your system by yourself, to do so may result in serious injury. The unit must only
be repaired by an authorised service agent.
You also report if the inspection mark
and the letters E, F, H, L, P in combination with the
numbers appear on the LCD of the remote control unit.
Should the power fail while the unit is running, or is temporarily cut off, the unit will automati-
cally resume operation once power is restored, using the same settings before the power was
interrupted.
