2.1 Intended use

Richter sight glasses of the series PSG/F and TSG/F

are pressure-maintaining components in accordance

with the Pressure Equipment Directive (PED) for the

passage of fluids.

They permit a view into the housing interior from two

opposite sides.

The valves are suitable for vapours, gases and liquids

of group 1 in accordance with the PED and have a

corrosion-resistant plastic lining.

The sight glasses serves to the monitoring of flow,

filling level, condition, colour and gas contents of

media in pipes and vessels and near pumps.

The operator must carefully check in the event of

operating data other than those provided whether the

designs of the strainer, accessories and materials are

suitable for the new application (consultation with the

manufacturer).

2.2 For the customer / operator

When using the valve, the operator must ensure that

 hot or cold valve parts are protected by the

customer against being touched

 the valve has been properly installed in the pipe

system

 the usual flow rates are not exceeded in continuous

operation.

This is not the manufacturer's responsibility.

Loads caused by earthquakes were not allowed for in

the design.

Fire protection to DIN EN ISO 10497 is not possible

(plastic lining and plastic components).

2.3 Improper operation

The operational reliability of the valve supplied is only

guaranteed if it is used properly in accordance with

Section 2.1

of this operating manual.

The operation limits specified on the

identification plate and in the pressure-

temperature diagram must under no

circumstances be exceeded.

3 Safety notes for applications in potentially explosive areas

based on the Directive 94/9/ EC (ATEX 95)

The valves are intended for use in a potentially

explosive area and are therefore subject to the

conformity assessment procedure of the directive

94/9/EC (ATEX).

As part of this conformity assessment, an ignition

hazard analysis to EN 13463-1 to satisfy the

fundamental safety and health requirements was

conducted with the following result:

 The valves do not have any ignition source of

their own.

 The valves are not covered by the scope of

application of the ATEX directive and therefore

do not need to be identified accordingly.

 The valves may be used in a potentially

explosive area.

It is imperative to observe the individual points of

intended use for application in a potentially explosive

area.

3.1 Intended use

Improper operation, even for brief periods, may

result in serious damage to the valve.

In connection with explosion protection, potential

sources of ignition (overheating, electrostatic and

induced charges, mechanical and electric sparks)

may result from these Improper operation; their

occurrence can only be prevented by adhering to

the intended use.

Furthermore, reference is made in this connection to

the Directive 95/C332/06 (ATEX 118a) which contains

the minimum regulations for improving the

occupational health and safety of the workers who

may be at risk from an explosive atmosphere.

A difference is made between two cases for the use of

chargeable liquids (conductivity < 10
