1. Important Safety Information
1.1 Health & Safety at Work Act 1974
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 for any technical advice or product information. 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 and to read the information in this manual.
1.2 Safety Messages and Hazard Statement
Table 1.1: Hazard Notice Definitions
1.3 Qualified Personnel
WARNING
This product is intended for operation by qualified personnel only
• Only qualified personnel are allowed to install or operate this equipment
• Qualified personnel are defined as trained staff, who are authorised to install, commission and maintain
equipment, systems and circuits in accordance with relevant laws and regulations. Personnel must be
familiar with the instructions and safety procedures described in this document.
• This product should not be used by anyone with mental disabilities, or anyone without the relevant
experience and knowledge, unless they have received instructions on using the equipment and on the
associated risks, or are supervised by a responsible person.
• Children must be supervised to ensure they do not play on or around the equipment.
1.4 Environmental Protection
All local regulations and codes regarding emissions and waste disposal must be followed. This may include:
• Reporting of emissions to appropriate authorities
Message Level Definition
DANGER A hazardous situation which, if not avoided, will result in death or serious injury
WARNING A hazardous situation which, if not avoided, could result in death or serious injury
CAUTION A hazardous situation which, if not avoided, could result in minor injury
or moderate injury
ELECTRICAL HAZARD Risks associated with electricity will cause hazards if not properly avoided
Note A situation which may arise resulting in undesirable conditions and/or will
not cause direct hazards to persons

• Sorting, recycling and disposal of solid or liquid waste
• Clean-up of spills
• Separate disposal of electrical components from domestic waste
1.5 Mechanical Device 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 item(s) will remain inoperative. Locking out the
equipment by switching off the release mechanism or set value WILL NOT prevent accidental starting.
• Allow the item(s) to cool if over-heated.
• CLOSE the isolating valves on the suction and discharge connections of the affected item(s).
• If working on pump, VENT slowly and cautiously – Refer to the relevant section of this manual.
• DRAIN the pump(s).
1.6 Pump Hand Control Mode (Where Fitted)
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 sufficient to provide constant flow through the pumps to maintain the running pressure of the system to an
acceptable level.
1.7 Personal Protective Equipment
Use personal safety equipment according to the site conditions and employer regulations. This may include, but
may not be limited to:
• Hard hat
• Safety goggles with side shields
• Protective footwear
• Protective gloves
• Respirator
• Ear protection
• First aid kid
• Safety devices
1.8 Precautions Before Commencing Work
Ensure that the following safety precautions are complied with before commencing work:
•Create a safe working area, and provide a suitable barrier around the work area
• Ensure all safety guards are in place and secure
• Ensure you have a clear path of exit
• Ensure that the product cannot roll or fall over and cause damage to persons or property
• Ensure all lifting equipment is in good condition and rated for the intended task
• Use a lifting harness, safety line and respirator as required
• Allow hot components to cool before handling them
• Ensure that product has been thoroughly cleaned
• Disconnect and lock out power supply, ensuring that it cannot be accidentally re-connected

• Check for any risk of explosion before using hand tools
1.9 Precautions During Work
• Never work alone
• Always wear protective clothing and hand protection
• Stay clear of suspended loads
• Always use appropriate lifting devices
• Beware of risks of sudden starts of any automated equipment such as level control
• Beware of starting jerks of electric motors - these can be powerful
• Do not exceed the stated operating limits of equipment
• Do not remove vent plugs from a pressurised system - ensure pressurised components are relieved of
pressure before disassembly
• Ensure guards are in place during operation
1.10 Hazardous Fluids and Chemicals
If hazardous chemicals come into contact with skin or eyes, use the following procedures:
1.11 Electrical Safety - High Voltages
This information is especially applicable when Variable Speed Controllers (Inverters) are fitted to pumps.
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.
DANGER!
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
restors.
ELECTRICAL HAZARD
Up to 800V 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 and
properly authorised personnel.
Condition Action
Chemicals or
hazardous fluids
in eyes
1) Hold your eyelids apart forcibly with your fingers
2) Rinse the eyes with eyewash or running water for at least 15 minutes
3) Seek medical attention
Chemicals or
hazardous fluids
on skin
1) Remove contaminated clothing
2) Wash the skin with soap and water for at least 1 minute
3) Seek medical attention
1. Important Safety Information

ELECTRICAL HAZARD
THE SYSTEM MUST ONLY BE OPERATED WHEN IT HAS BEEN CORRECTLY EARTHED AND PIPES
BONDED TO EARTH IN ACCORDANCE WITH IEE REGULATIONS
• 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.
1.12 Electronic Safety Devices
• Inverter drives contain electronic safety devices which switch off the control element in the event of a fault
developing.
• A motor can also be stopped by ‘mechanical blocking’
• If it is switched off electronically, the motor is disconnected from the mains voltage supply via the electronics
in the inverter drive.
• Voltage fluctuation and power failures (temporary outages) can cause the motor to switch itself off.
WARNING
A motor will have zero current but will remain energised as it stops
• Take necessary precautions - the motor is not voltage-free in the circuit itself
WARNING
Repair of faults can cause items to start up again unexpectedly
Ensure the motor is isolated before commencing any work
WARNING
High voltage tests of inverters may damage the electrical 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.
1.13 Spare Parts
WARNING
Use of non-genuine spare parts may cause damage to equipment, damage to property and voiding of
warranty
• Use genuine, Dutypoint-approved spare parts only
• If in doubt, contact Dutypoint Service on 01452 300590.
