1. Note
For this test, pressure gauges must
be fitted to the flow and return of
the hydraulic circuit.
As an alternative, pressure gauge
connectors must be available.
When a load of at least 60% is
drawn, check the pressure at the
return (p2) and the flow (p1) of the
unit.
2. Calculate the available pressure
from the pressure differential
between the unit flow and return
(p1 – p2).
3. Using the pump curves from
page 53 check at what pump set-
ting, starting from the available
delivery pressure, the required
water throughput will be achieved
(see the following example).
4. If necessary, change the pump set-
ting (see section "Adjusting the
pump rate" on page 21).
5. Check the pressure again.
