1.1 Document Conventions
Throughout this manual, text may be accompanied by one of the following icons. Where these
occur the conventions shown below are applied.
In general these conventions will also apply to OEM Manufacture’s manuals that are included
within this User Guide, however variations may occur, but these will be redefined at the beginnin
of their manual.
PLEASE READ THE FOLLOWING INFORMATION WHICH IS PROVIDED FOR YOUR SAFETY
Danger: Denotes attention to the possibility of the risk of personal
injury or damage to adjacent property if the information is ignored.
Electric Shock: Denotes attention to the possibility of life-threatening
electric shock if the information is ignored.
Warning: Denotes attention to a condition that may result in under-
performance or damage to the equipment if the information is ignored.

Note: Denotes attention to an important factor applicable to the action
being performed.

1.2 Health and Safety Information
Basic safety warnings relating to all products.
United Kingdom Health & Safety at Work Act 1974
Dutypoint Responsibility
Section 6(a) of this Act requires manufacturers to advise their customers on the safety and the handling
precautions to be observed when installing, operating, maintaining and servicing their products. The user’s
attention is therefore drawn to the following:
• The appropriate sections of this manual must be read before working on the equipment.
• Installation, operating and maintenance must only be carried out by suitably trained/qualified personnel.
• Normal safety precautions must be taken and appropriate procedures observed to avoid accidents.
Refer to DUTYPOINT SYSTEMS for any technical advice or product information. 
Customer / Contractor Responsibility
It is the responsibility of the customer and/or the contractor: 
• To ensure that anyone working on the equipment is wearing all necessary protective gear/clothing.
• Is aware of appropriate health & safety warnings
• has read the information in this section of the manual.

Hand Control Mode
In the 'HAND' position the pump(s) controlled by the switch will normally run at full speed and completely
independently of any control devices, and can result in pump(s) running against a closed valve head if there is no
draw.
This can cause the system to be maintained at the maximum pressure produced by the pump plus any incoming
pressure and additional pressure caused by water surge and can potentially damage the pump and other parts of
the system.
The 'HAND' option should only be used with a competent operator in attendance, or when there is a
continued demand sufcient to provide constant ow through the pumps to maintain the running pressure
of the system to an acceptable level.
Pump Servicing
• Familiarise yourself with the relevant contents of this manual
• Installation, maintenance and repair work must only be carried out by trained, skilled and suitably
qualified personnel
• Disconnect or lock-out the power source to ensure that the pump(s) will remain inoperative. Locking out
the equipment by switching off the release mechanism or set value WILL NOT prevent accidental
starting of the motor.
• Allow the pump(s) to cool if over-heated.
•CLOSE the isolating valves on the suction and discharge connections of the affected pump(s).
•VENT the pump(s) slowly and cautiously – Refer to the relevant section of this manual.
•DRAIN the pump(s).

High Voltages
Especially applicable when Variable Speed Controllers (Inverters) are tted.
• When the inverter variable speed drive head is connected to the power supply the components of the power unit
– as well as certain components of the master control unit – are also connected to the power supply.
TOUCHING THESE COMPONENTS CAN SERIOUSLY ENDANGER LIFE!
• Before removing the frequency inverter cover, the system must be disconnected from the power supply. After
switching off the power supply wait at least 5 minutes before starting work on or in the inverter drive head – the
capacitors in the intermediate circuit must be given time to discharge completely via the discharge resistors.
Up to 800 volts can be present – if there are faults this can be higher.
• All work carried out when the frequency inverter is open must be performed only by suitably qualified an
properly authorised personnel.
When connecting external control wires care must be taken not to short circuit adjacent components. Bare cable
ends which are not in use must be insulated.
THE SYSTEM MUST ONLY BE OPERATED WHEN IT HAS BEEN CORRECTLY EARTHED AND PIPES BONDED TO
EARTH IN ACCORDANCE WITH IEE REGULATIONS
Electronic Safety Devices
• High voltage tests of the inverter or the motor may damage the electronic components. Bridge before
the incoming/outgoing terminals L-L2-L3 and U-V-W.
• To avoid incorrect metering by capacitors incorporated in the electronic circuits, isolate the motor from
the inverter drive head.
