4. After transfer to pre-emergency mode, the device
produces 6 automatic trial starts of 30 seconds
each – in 5, 20 and 60 minutes and then – in 6, 12 and 24
hours. When water appears during any trial starts, the
pump is automatically switched on and transferred to
pump mode.
5. In the absence of water during full cycle of trial starts,
the pump is switched off and transferred to emergency
mode.
6. Exit from emergency mode is made by pressing button
(8) or manually by disconnecting the control unit from
power line for not less than 6 seconds.
ATTENTION!
The control unit can enter emergency mode not
only in the absence of water flow but also when supply voltage
drops below 170 V, in case of improper installation, impeller
jamming and in other emergency situations. Before restarting the
device, make sure that the cause of accident is eliminated.
It is not permissible to use the pump at very low water flow - less
than 2 l/min.
