3. INSTALLATION AND OPERATION
3.1 Installation instructions
All deliveries of compressor installations are accompanied by documentation of the installation’s dimensions
and mounting points. The documentation will also include installation instructions, showing the recommended
assembly of equipment and pipe connections.
To achieve problem-free operation, it is important that the base-plate is sufficiently rigid and free from vibrations
caused by other machinery. The base of the compressor must lie flat on the base-plate. After installation of the
compressor, the alignment between the compressor and its drive motor should be checked.
The compressor installation should be located where the ambient air is as cold as possible. Warm intake air
reduces the capacity of the compressor and increases the risk of coking. The ambient temperature for the
electrical components must not normally exceed 45°C. The base of the compressor must lie flat on the base-
plate. After tightening the fixings, the alignment between the compressor and motor must be checked as
described in Section 5.6. (Even if the installation is mounted on vibration dampers, it is recommended that the
alignment is checked after installation.)
The cooling water pipes must be installed in such a way the air pockets cannot occur.
The compressor installation should not be closely surrounded by other equipment which would hinder
maintenance work.
3.2 Cooling water system
A reliable and adequate cooling water supply is important for the functioning and life-expectancy of the
compressor. The necessary cooling water capacities are specified in Table 6.1, and apply both to seawater and
freshwater cooling.
Whether the compressor is connected to a central cooling system or is equipped with a separate cooling water
pump, it is important to ensure that cooling water circulation is maintained, and the indication of cooling water
pressure by the manometer alone is not sufficient proof of this. It is recommended that the cooling water
circulation be shut off when the compressor is not running, to avoid the precipitation of condensation in the
crankcase.
Too low temperature of the cooling water entering the compressor may lead to an increase in internal
condensation formation, and if this occurs, the temperature of the cooling water should be increased. If it is not
possible to increase the temperature, for example by recirculation, condensation formation may be reduced by
reducing the amount of cooling water within the limiting values specified in Table 6.2.
A thermometer is mounted in the cooling mantle on the cylinder head to monitor the cooling water temperature.
