Explanation:1. FK-40 Compressors can be operated in the range of the diagram above.2. No supplementary cooling is necessary for operation within the non-shaded area.3. Supplementary cooling is only necessary in the vertical shaded area when the suction gas superheat exceeds 20K.
4. The following applies if operation proves necessary within this range:
It is advisable to use a thermal protective thermostat(accessory).Only highly thermostable oils are to be usedIf capacity regulators are temperature may prove necessary.Individual setting necessary(the max. discharge end temperature of +140°C must not be exceeded).
