4.2 Oil charge
The compressors are filled at the factory with the following oil type:
- for R404A/R507
- for R22
Compressors with ester oil charge ( BOCK lub E55 ) are marked with an X in the type
designation (e.g. HAX34e/315-4).
ATTENTION The oil level must be in the

damage to the compressor
is possible if overfilled or
underfilled!
These can be found in Bock compressor selection tool (VAP) under
vap.bock.de. Observe the information given there.
- Max. permissible ambient temperature 45°C.
- Max. permissible discharge end temperature 140°C.
- Max. permissible switching frequency 12x /h.
- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
For operation with capacity regulator:
- Continuous operation, when the capacity regulator is activated,
is not permissible and can cause damage to the compressor.
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
- When the capacity regulator is activated, the gas velocity in
the system can not under certain circumstances ensure that
sufficient oil is transported back to the compressor.
For operation with frequency converter:
- The maximum current and power consumption must not be
exceeded. In the case of operation above the mains frequency,
the application limit can therefore be limited.
(For more on the subject of frequency converters, see chapter
7.14, p. 27)
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!
