1.3 General safety instructions

DANGER! •Refrigerating compressors are pressurised machines and as such

call for heightened caution and care in handling.

The maximum permissible overpressure must not be exceeded,

even for testing purposes.

WARNING! •Risk of burns! Depending on the operating conditions, surface

temperatures of over 60°C on the discharge side or below 0°C on

the suction side can be reached.

WARNING! Inadequately qualied personnel poses the risk of accidents, the

 consequencebeingseriousorfatalinjury.Workoncompressorsis

 therefore reserved for personnel with the qualications listed

3|Areas of application

ATTENTION! Compressor operation is possible within the limits of application

showninthediagrams.Pleasenotethesignicanceoftheshaded

areas. The limits of application must be observed. Thresholds

should not be selected as design or continuous operating points.

    -Max.permissibleambienttemperature:100°C

    -A minimum running time of 2 min. at equilibrium (continuous

operation) must be achieved.

Avoid continuous operation near the threshold. Should the com-

pressor happen to be used near the thresholds, we recommend the

useofathermalprotectionthermostat(Accessories,Chap.7).

When capacity regulators are used, the limits of application can

move.

When operating in the vacuum range, there is a danger of air en-

tering on the suction side. This can cause chemical reactions, a

pressure rise in the condenser and an elevated compressed-gas

temperature. Prevent the ingress of air at all costs!
