Maintaining the Unit
Maintenance activities
In order to ensure optimal availability of the unit, a number of checks and inspections on the unit and
the field wiring have to be carried out at regular intervals, preferably yearly.
This maintenance should be carried out by SAMSUNG local technician. Besides keeping the remote
controller clean by means of a soft damp cloth, no maintenance is required by the operator.
WARNING
During longer periods of standstill, e.g. during summer with a heating only application, it is very
important NOT TO SWITCH OFF THE POWER SUPPLY towards the unit.
Switching off the power supply stops the automatic repetitive movement of the motor in order to
prevent it from getting jammed.
