The pumps can be operated in manual mode in two different ways.
▪
Each pump can individually be operated in manual mode by using the multi-
functional button of the control panel. Select the desired pump by pressing the
multi-functional button either once or twice and holding it down. The
corresponding pump will then be operated in manual mode as signalled by the
blinking green LED.
▪
A manual-0-automatic selector switch is provided for each pump at the control
cabinet, which makes it possible to operate each pump in manual mode. The
"manual" position is momentary, i.e. the manual-0-automatic selector switch
snaps back to the "0" position when released.
NOTE
Continuous manual mode is reserved exclusively for emergencies!
Continuous operation of the pressure booster system in manual mode may result in
waste of energy and water.
Continuous operation of the pressure booster system in manual mode may cause
the fluid handled and the pump to overheat.
In manual mode, a minimum flow (as shown in table below) is essential to prevent
the fluid handled and the pump from overheating when no water is consumed at the
consumer installations.
