1.6 Safety

1.6.1 Summary of safety markings

These User Instructions contain specific safety

markings where non-observance of an instruction would

cause hazards. The specific safety markings are:

This symbol indicates electrical safety

risk to personal safety or the loss of life.

This symbol indicates safety instructions where

non-compliance would affect personal safety and could

result in loss of life.

This symbol indicates safety instructions

where non-compliance will involve some risk to safe

operation and personal safety and would damage the

equipment or property.

instructions where non-compliance in the hazardous

area would cause the risk of an explosion.

This symbol is used in safety instructions to

remind not to rub non-metallic surfaces with a dry

cloth; ensure the cloth is damp. It is used in safety

This sign is not a safety symbol but indicates

an important instruction in the assembly process.

1.6.2 Personnel qualification and training

All personnel involved in the operation, installation,

inspection and maintenance of the unit must be

qualified to carry out the work involved. If the personnel

in question do not already possess the necessary

knowledge and skill, appropriate training and instruction

must be provided. If required the operator may

commission the manufacturer/supplier to provide

applicable training.

Always coordinate repair activity with operations and

health and safety personnel, and follow all plant

safety requirements and applicable safety and health

laws and regulations.

1.6.3 Safety action

This is a summary of conditions and actions to

help prevent injury to personnel and damage to

the environment and to equipment. For products

used in potentially explosive atmospheres

section 1.6.4 also applies.

NEVER DO MAINTENANCE WORK

WHEN THE UNIT IS CONNECTED TO POWER

Before maintenance and repair work is started the

motor of the pump unit must first be completely

isolated from the electrical power supply.

The procedure to shut down the unit described in

section 7.3, Switching off the unit, must be followed

without fail.

Danger from electricity must be

eliminated. (For details see, for example, the

regulations of the VDE and local power supply

companies.)

GUARDS MUST NOT BE REMOVED WHILE

THE PUMP IS IN OPERATION

HANDLING COMPONENTS

Many precision parts have sharp corners and the

wearing of appropriate safety gloves and equipment

is required when handling these components. To lift

heavy pieces above 25 kg (55 lb) use a crane

appropriate for the mass and in accordance with

current local regulations.

DISMOUNTING PUMP UNITS

Before dismounting one pump unit, the pump must be

separated from the motor and drained. In case of

dangerous delivery fluids, suitable safety measures

must be made.

THERMAL SHOCK

Rapid changes in the temperature of the liquid within

the pump can cause thermal shock, which can result

in damage or breakage of components and should be

avoided.

HOT (and cold) PARTS

If hot or cold components, or heater or cooler units,

can cause a danger for the operating staff or persons

in the immediate vicinity, measures must be taken to

prevent possible contact, eg by protective gratings.
