Procedure for lift suction
Lift Suction is defined where the water storage tank is at a lower level than the pumpset. In this
case a negative pressure condition may exist at the pump suction.
WARNING: The "Lift Suction" mode of operation required specific venting procedures.
Please call Dutypoint Systems Technical Support on +44 (0)1452 300592 for advice before
attempting to vent the pump(s).
The advised procedure should then be carried out individually for each pump in the pumpset.
4. Programming the Controller
Dutypoint Systems fit a design of Inverter/Controller that is most suitable for the design duty of the
Pumpset.
Section 3 of this manual details the type of controller used in the various models, and
manufacturer’s information for them is detailed in the Appendices to this manual.
Carefully follow the appropriate step-by-step setting-up procedures contained in the manual,
ensuring that any data required to be entered by the end user is accurately inserted where
requested.
If in doubt please call Dutypoint Systems Technical Support on 01452 300592 for advice.
5. Operational and Performance Tests
Having checked that the Pumpset is installed, precharged, vented in accordance with the
procedures set out earlier, carry out the following running tests before handing over the Pumpset
for operational use.
1. Run each pump by selecting HAND (Manual) control.
2. Re-select to AUTO mode.
3. Create the conditions for a normal start and run and allow the selected ‘Duty’ pump to run.
Whilst running observe the pressure values. Verify the pump motor speeds up / slows
down in accordance with the desired control philosophy.
Duty/Standby Sets
1. On Duty/Standby sets, wait for a normal stop to take place (or create the conditions where
this would happen) and check that the ‘Duty’ pump stops. Whilst stopped simulate a fault
