4.7 Minimum pressure
The minimum pressure in the pump connection
to ensure lubrication of the friction bearings:
<75 °C 0,6 bar overpressure
95 °C 1,0 bar overpressure
110 °C 1,7 bar overpressure
The values apply up to 500 m above sea level.
Additions for higher altitudes:
0.01 bar per 100 m of altitude
Addition for: 95 °C + 0,45 bar
Addition for: 110 °C + 1,10 bar
Install the sluice gate before and after the pump.
This prevents the fluid from being drained and refilled
when the pump is exchanged.

4.6 Return valve
If a return valve has been installed, the pump has to be set up
(see point 7.2) so that the pump’s minimum delivery pressure
can exceed the valve’s closing pressure at any time.
