9.3 Hydro Multi-E in system without inlet pressure
When you have carried out the mechanical and electrical
installation described in section 6. Installation, proceed as
follows:
1. Check that Hydro Multi-E corresponds to the order and that no
single parts have been damaged.
2. Check that the precharge pressure in the diaphragm tank is
0.7 times the required outlet pressure (setpoint).
3. Connect water and power supplies to the system.
4. Open all pump inlet valves.
5. Close all pump outlet valves, and prime all pumps and the
inlet pipe.

6. Switch on the power supply with the main switch.
7. Start pump 1 by pressing the start/stop button on the pump
control panel.
8. Vent pump 1 using the vent screw.
9. Slowly open the outlet valve approximately 50 %.
10.Repeat steps 9 and 11 for the other pumps in the system.
11. Slowly fully open all pump outlet valves.
12. Wait for a few minutes.
13. Set the desired outlet pressure.
14.Check that the pumps are cutting in and out, thus adjusting
the performance to the demand.
Hydro Multi-E is now in automatic mode and ready for operation.
The standard settings can be changed using Grundfos Go
Remote, see section11. Multimaster function or advanced control
panel.
10. User interfaces
You can configure pump settings using the following user
interfaces:
• Standard control panel
See section 10.1 Standard control panel.
• Advanced control panel
See section 10.2 Advanced control panel
• Grundfos GO Remote.
See section 11. Multimaster function.
If the power supply is switched off, the settings will be stored.

Make sure that the power is switched off on the main
switch and the circuit breakers.
Do not start the pumps until they have been filled
with liquid.
Hydro Multi-E systems with CME pumps require a
positive inlet pressure during startup and operation.
The following startup procedure therefore only
applies to Hydro Multi-E systems with CRE or CRIE
pumps.
Measure the precharge pressure while the system is
pressureless.

If you change the outlet pressure, change the
diaphragm tank precharge pressure accordingly.
