Installation and assembly
24
Assembly 1. Install the safety valve directly after the compressor. There
may not be any shut-off devices between the safety valve and
the compressor.
2. The nominal opening pressure may not exceed the maximum
permissible final overpressure (refer to chapter 3.2 Tab. 2) or
the permissible system pressure, provided the latter is lower.
6.9.2 Non-return valve
The non-return valve prevents the reverse operation of the
compressor after it has been switched off when the silo is not
relieved. The non-return valve is not suitable for retaining material
to be conveyed.
Assembly

The non-return valve must be installed directly after the
compressor or after the safety valve.

A second non-return valve must be installed at the crossover
to the consumer.
6.9.3 Suction filter
Liquids and solids may not be sucked in. Hence, a filter must be
installed before the compressor.
Requirements The filter must fulfil the following requirements:

Filter: < 5 Micron

Filter resistance when it is new: < 30 mbar

It must be fitted with dust extraction valve, a control flap and
a maintenance display for the degree of contamination.
Assembly

Install the filter in the suction line before the compressor

either directly before the compressor with an intake silencer
or away from the compressor via a connecting hose.

Protect the filter from spray water, exhaust gases and heat.

Observe the flow direction.

Mount the filter horizontally.

It must be possible to dismantle the filter cartridge for
maintenance.
6.9.4 Protection against contact
Moving and hot parts must be protected against contact.
The protective measures for moving parts, e.g. to DIN EN ISO
13857, for hot surfaces, e.g. to DIN EN ISO 13732-1, must be
implemented.
