Valves The pump is equipped with a non-return valve (1)
on the pressure side and with a ball shut-off
valve (2) on the suction side.
When replacing the motor head (3), it is sufficient
to de-energise it by unplugging the connector (5)
and to close the ball shut-off valve at the rotating
slot (4). The motor head can then be simply
unscrewed.
If the pump is switched off by the time-switching
function, the pump switches on automatically
for 10 seconds once every 60 minutes. This auto-
matic function cannot be switched on/off.
