immediate fatal or serious injury.
WARNING! Indicates a dangerous situation which, if not avoided,
may cause fatal or serious injury.
CAUTION! Indicates a dangerous situation which, if not
avoided, may cause fairly severe or minor injury.

WARNING! Inadequatelyqualifiedpersonnelposestheriskofaccidents, theconsequencebeingseriousorfatalinjury.Workon compressors is therefore reserved for personnel with the qualificationslistedbelow: •Forexample,arefrigerationtechnician,refrigerationmechatronic engineer. Aswellasprofessionswithcomparabletraining,whichenables personneltoassemble,install,maintainandrepairrefrigerationand air-conditioningsystems.Personnelmustbecapableofassessing theworktobecarriedoutandrecognisinganypotentialdangers.
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.

3| Areas of application
ATTENTION! Compressor operation is possible within the limits of application showninthediagrams.Pleasenotethesignificance of the shaded areas. The limits of application must be observed. Thresholds should not be selected as design or continuous operating points.
-Max.permissibledischargeendtemperature:140°C -Max.permissibleambienttemperature:100°C -Max.permissibleswitchingfrequency:12x/h -Aminimumrunningtimeof2min.atequilibrium(continuous operation) must be achieved.
Avoid continuous operation near the threshold. Should the compressor happen to be used near the thresholds, we recommend the use of a thermal protection thermostat (Accessories,Chap.7).
When operating in the vacuum range, there is a danger of air entering 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!
