Operating the Pump System
ATTENTION !
Avoid operating the pump without water for longer than 3 minutes.
Operation without water supply can result in damage of the pump
shaft seal.
The pump pressure should exceed 2 bar, otherwise the priming
pump will not be disengaged by the water pressure.
Drafting operation from open water source
- Connect pressure hoses to the pressure outlets (J11) on the left
and/or right hand sides.
- Connect suction hoses to connection(s) (J15) on the left and/or
right hand sides.
- Open drafting valve(s) (J14) on the left and/or right hand sides.
- Engage the water pump:
◊
Please refer to the "Engaging the Water Pump" chapter.
◊
The water tank suction valve opens automatically.
- Close the water tank suction valve:
◊
Press switch (SF1).
Note:
Press switch (SF1) during the water pump is engaged; this is to
prevent automatically opening of the water tank suction valve.
◊
The priming pump is engaged automatically until a pressure
of 2 bar is achieved (visible on water pressure gauge (P28)).
If required the engine accelerate automatically.
◊
The pilot lamp (H9) remains illuminated as long as the
priming pump is engaged.
◊
In case the pressure drops below 2 bar the priming pump will
be re-engaged automatically.
- Open the left and/or right discharge valve(s) (J10) slowly and
start fire fighting.
- Adjust required discharge pressure:
◊
Press switch (S9+) to increase the pump speed.
◊
Press switch (S9-) to decrease the pump speed.
Note:
If the automatic priming process fails the pump system can be
evacuated by using switch (SF5) until a pressure (max. 2 bar) is
achieved (visible on water pressure gauge (P28)).
A priming process can be disengaged by pressing switch (SF5).
Call up pump main menu by using switch (S466).
