1. Drainage
•
•
•
Note: 1. The diagram shows the connections for the water supply. When draining, change the connection from terminal Tb1 to terminal Ta1.
Connect the electromagnetic switch terminal (T phase) to Ta1
The pump starts (U2 indicator ON) when the water level reaches
E1 and stops (U2 indicator OFF) when the water level drops
below E2.
If the water level reaches E4 for any reason, the alarm sounds
(U1 indicator ON).
2. Be sure to ground terminal E3.
