SAFETY MEASURES
1. Installation and electrical connection should be made by
qualied specialists in strict accordance with “Rules for
Technical Operation of Electric Installations of
Consumers” and “Safety Code for Technical Operation of
Electric Installations of Consumers”.
2. Before any operations, disconnect the device from power
line and open valves in order to blow the system pressure
down.
3. It is prohibited to use the control unit without grounding.
4. It is prohibited to use with upper cover removed.
5. The device dismounting and repair shall be performed
only by maintenance specialists.
OPERATION ALGORITHM
1. At water ow rate of more than 2 l/min, the pump is
switched on and starts to pump water continuously
(pump mode).
2. The device can operate in two modes – basic mode and
temporary mode.
Basic mode:
The pump is automatically switched off at the system
pressure Pmax and switched on at pressure drop to Pmin
Temporary mode:
This mode is automatically set when the pump, for a v
riety of reasons, cannot build up Pmax. In this case the
pump is switched off with 30-second delay when water
ow stops and rate thereof drops to 2 l/min. The pump
is switched on when water ow appears (>2 l/min) but
not earlier than in 2 seconds after the pump switching off.
3. In the absence of water ow and the system pressure
drop to Рmin, the pump is switched on and operates
during 30 seconds. If after thirty-second interval water
ow rate is not more than 2 l/min, the control unit is
ztransferred to pre-emergency mode.
