4. Set the "Auto-Manual" switch for all pumps to "Manual". The switch is located on the front of the control cabinet. Fig. 4 Correct lifting of Hydro Multi-B with CM and CME 5. Close all pump outlet valves, and prime all pumps. See the pumps installation and operating instructions for the pumps. -
Page 6: Product Introduction
5. Product introduction 5.1 Product description Hydro Multi-B is a range of factory-assembled booster systems, ready for installation and operation. As standard, the booster systems consist of two to four pumps connected in parallel and mounted on a common base frame with a control cabinet and all necessary fittings. - Page 7 5.2.1 Booster system for constant-pressure applications Operating principle The user enters the required pressure of the system (setpoint) via The booster system for constant-pressure applications is the user interface of the CU 323 control unit. CU 323 adjusts the designed to maintain a constant pressure on the outlet side of the system performance according to the feedback received from the pumps.

Control variants The booster systems for tank-filling applications are available as control variants E and ES. Both systems work as described below. Control variants E and ES E: Two to four electronically speed-controlled pumps ES: One to three mains-operated pumps and one speed-controlled pump Pump speed 100 % 70 %... - Page 9 CUE or VFD. In these cases, all pumps are fixed-speed pumps. ** Hydro Multi-B, ES systems, are only shown with the E-pump description, meaning that the fixed-speed pumps have the same size, number of stages, material combination and kW.

Page 12: Operating Modes
7. Operating modes User operation depends on the system mode. The system modes are described in the following sections. 7.1 Local mode, external stop not activated In this mode, the system is locally controlled, and the external stop via digital input is not activated. The flow charts below show examples of how settings can be made. -

7.3 Remote-controlled, external stop not activated In this mode, the system is remote-controlled, and the external stop via digital input is not activated. If you want to change the local settings, follow the flow chart examples below. Keep the buttons pressed for 3 seconds. See section 7.1 Local mode, external stop not activated... -
Page 14: Adjusting The Proportional-Pressure Setpoint
7.5 Adjusting the proportional-pressure setpoint The function has these purposes: • to compensate for pressure losses Description • to reduce the energy consumption You can only enable this function in pressure-controlled systems. • to increase the comfort for the user. The function automatically adapts the setpoint to the actual flow rate to compensate for flow-dependent dynamic losses. -

The limit for the minimum inlet pressure in the inlet manifold is a pumps is running. This means that the number of running pumps factory-set value which can only be changed by a Grundfos always corresponds to the required flow at the entered setpoint. - Page 16 8.2.3 Maximum pressure exceeded 8.2.6 Proportional-pressure control mode This function protects the piping on the outlet side of the booster The proportional-pressure control mode is only available for system against damaging high pressures. The pressure is E-pump systems. monitored, and if the pressure is higher than 1.5 bar above the Description setpoint for more than 5 seconds, the pumps are stopped, the You can only enable this function in pressure-controlled systems.
