Transporting the plate heat exchanger:

Before transporting the plate heat

exchanger, always ensure that the hoisting

gear is of sufficient dimensions and

securely fixed. Never step underneath

suspended loads.

Hazardous flow media: Hazardous flow

media present dangers of chemical burns,

burning or poisoning. Always wear suitable

protective clothing when working on a heat

exchanger that has hazardous flow media.

OPERATING INSTRUCTIONS:

These operating instructions are for

operators of heat exchangers and for

all persons who are responsible for the setup, operation,

maintenance and repair of the device. These operating

instructions are generally applicable to all gasketed plate heat

exchangers supplied by Aurora.

USER NOTES, DRAWINGS AND FIGURES. The drawings

in these operating instructions show typical examples. For

reasons of clarity, some drawings have been greatly simplified.

The actual details depend on the individually delivered heat

exchanger. You will find diagrams and dimensions of the heat

exchanger in the technical documentation supplied.

Note for the operator of the heat exchanger. The operator of

the plate heat exchanger is the person who is in charge of the

operation of the device.

Note for the technician who sets up the heat exchanger. These

operating instructions contain no details about special tools

that are needed for the setting up and operating the plate heat

exchanger.

SAFETY NOTES IN THE TEXT. In these operating

instructions, the following are used in order to draw your

attention to dangers when handling the heat exchanger or

provide you with information about handling the heat

exchanger:

CAUTION. This means danger to the life and health of persons.

The following text explains the type of danger and its effects

heat exchanger. This information helps you to avoid problems

and makes it easier to handle the plate heat exchanger.

MANAGER'S OBLIGATIONS:

CAUTION

Danger of injury!

In the case of hazardous media (acids or similar media), high

pressures and high/low temperatures in the heat exchanger,

there is a danger of injury during maintenance or in the case of

leakages.

1. In this case you should use a protective shroud.

2. This shroud should be removed only when the heat

exchanger reaches room pressure and room temperature, or

is empty.

As manager of the plate heat exchanger you must ensure that

each operator who is responsible for the setup, operation,

maintenance or repair of the heat exchanger has read and

understood, from beginning to end, the parts of the operating

instructions important for the job.

The heat exchanger is built according to state-of-the-art

technology and is reliable in service. In spite of that, the heat

exchanger may present dangers or may be damaged if you do

not observe the following instructions:

1. These operating instructions must always be accessible to

the operators entrusted to work on the heat exchanger.

2. Only operators who are instructed in handling the

heat exchanger and the basic work safety and accident

prevention regulations should work on the heat exchanger.

For safety reasons it should be forbidden for other persons

to be in the area of the heat exchanger.

3. The safety knowledge of the operators should be checked

regularly.

4. As manager you should ensure that:

a. The heat exchanger remains in functional order.

b. No premature wear of specific parts of the heat exchanger

results from unfavorable ambient conditions.

c. Unfavorable ambient conditions for the gaskets might

include:

• Aggressive gases and/or aggressive aerosols in the

surrounding air.

• Effects of UV radiation (e.g. sunlight).

• Extreme ambient temperatures.

d. Unfavorable ambient conditions for the metal

components might include:

• Aggressive gases and/or aggressive aerosols in the

surrounding air.

• Humidity.

e. All maintenance/inspections are carried out in regular

intervals.

f. No changes or modifications are carried out on the plate

heat exchanger without being checked by an appropriate

party to be sure that the modifications will not result in

unsafe operation.

g. All appropriate laws and regulations, even if they are not

explicitly mentioned here, are observed.
