5.2.7
Water level in the rinsing tray
The water level in the rinsing tray is changed by turning the floater (47) at the
floater control valve (32) in or out. Turning the floater out results in a higher lever,
turning it in results in a lower level. One rotation corresponds to approx. 1cm.
Adjust the floater (47) in the rinsing tray, so that the water level is approx. at the
middle of the rinsing tray.
5.2.8
Bleeding the feed pump
ATTENTION !
The feeding pump must be bled before switching on! There is
otherwise a risk that the pump overheats.
The feed pump must be bled when the buffer tank is filled for the first time (without
dosing of chemicals). The ball valve (
Pos. 60
Figure 10, Page 18
) in the bleeding
line, which leads back to the container, is opened and the pump is started by
pressing the OK button. The pump is bled after approx. 15 seconds, when the
water flows back into the container, and the ball valve must again be closed.
5.2.9
Setting the pump pressure of the feed pump / pressure retention valve
(option)
1.
Open all stop valves and control valves in the dosing lines
2.
Set the calculated flow values at the membrane valves of the feed system.
3.
The pressure retention valve is set in the factory. Increase
the pump pressure at the pressure retention valve (DHV
behind the mounting plate as required, when the necessary
performance is not reached. The pressure to the dosing
lines can be increased by turning the adjustment screw on
the pressure retention valve to the right and it can be
reduced by turning the screw to the left. Versions with a
frequency converter pump have a potentiometer for
stetting the rotation speed or pump performance at the
side of the pump.
