• 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 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
7
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
