1. General
1.1 Applications
Grundfos booster sets Hydro 1000 are designed for the transfer and pressure boosting of clean water in waterworks, blocks of flats, hotels, industry, hospitals, schools, etc.
1.2 Operating conditions
Liquid temperature: Maximum +50°C. Ambient temperature: 0°C to +40°C. Operating pressure: Maximum 10 bar. Minimum and maximum
inlet pressures: See installation and operating
instructions for CR pumps.
Liquid temperature and operating pressure may be limited by the diaphragm tank.
2. Product description
2.1 Grundfos Hydro 1000
The booster set consists of 2 to 4 pumps mounted on a common base frame, isolating valves, non-return valves, suction and dis­charge manifolds with pressure switches and a control box com­plete with the controller CS 1000.
Note: A diaphragm tank must be included in the installation. Dia­phragm tanks can be connected directly to the discharge mani­fold.

2.2 Grundfos Control 1000
The Grundfos Control 1000 controls a number of mains-operated pumps.
The Control 1000 always includes the controller CS 1000 and of­fers the following functions:
• Automatic cascade control of pumps.
• Manual operation.
• Pump and system monitoring functions:
- maximum pressure,
- pre-pressure / level,
- motor protection.
• Display and indication functions:
- green indicator lights for operating indications and red indicator lights for fault indications,
- potential-free changeover contact for fault indications.

2.3 Monitoring and indication functions
The following functions are available:
• Red indicator lights (LED) for indication of fault conditions:
- maximum pressure (if a pressure switch is installed),
- dry-running protection (if a pressure switch is installed),
- motor protection.
• Green indicator lights (LED) for indication of operating condi­tions:
- power on,
- automatic operation,
- pump in operation.
• Potential-free changeover contact for fault indications.

Grundfos Hydro 1000 CS maintains an almost constant pres­sure by cutting in/out the required number of pumps. The CS 1000 alters the starting sequence of the pumps after each pump stop, thus giving all pumps equal operating time. Pump changeover is automatic and depends on load and fault.

Function
Power indication. The green indicator light is on when the electricity supply to the CS 1000 is connected.
Dry-running alarm. The red indicator light is on when the dry-running alarm is activated. The light goes out when the alarm is reset. If automatic resetting is chosen, the indica­tor light goes out automatically when nor­mal operating conditions are achieved.
Maximum pressure alarm. The red indicator light is on when maximum pressure is acti­vated. The light goes out when the alarm is reset. If automatic resetting is chosen, the indicator light goes out automatically when normal operating conditions are achieved.
Reset button. Resets the dry-running alarm and the maximum pressure alarm if auto­matic resetting has not been chosen.
Automatic operation. The green indicator light is on when the pump is released and ready for operation.
Pump alarm. The red indicator light is on when the thermal relay of the pump is acti­vated. The pump is out of operation. The alarm can be reset on the thermal relay.
Pump in operation. The green indicator light is on when the pump is operating.
Auto button. When the auto button is pressed, the pump will be released for op­eration and the indicator light for automatic operation will be lit.
Stop button. When the stop button is pressed, the pump will be taken out of op­eration and the indicator light for automatic operation goes out.
Test button. The pump is operating as long as the test button is pressed. The maxi­mum pressure and the dry-running protec­tion are not activated as long as the button is pressed.
