Before opening the unit, disconnect the sys-
tem from the power supply and prevent it
from being switched back on!
The motor of the GKR 5 - 20 units is a single phase motor
with only one rotational speed. This is controlled by the
transformer.
The transformer has a terminal strip with eight termi-
nals, with which the motor supply and the conductor for
controlling the operating speed are wired.
