What should be considered for ECOLITE condensing units with regard to the pressure relief valve, its connection to the accumulator and the adjustable mechanical pressure switch?

The connection for a pressure relief valve on the accumulator is available as an option from the factory.
If the optional check valve between condenser and accumulator has been selected, the connection is automatically selected, too, during configuration.
The pressure relief valve is not included in the scope of delivery.

Whether the use of a pressure relief valve is necessary must be determined by the manufacturer of the refrigeration system – based on the locally applicable regulations and standards.
The manufacturer must also determine the valve, placement and mounting.

If a pressure relief valve is installed, the cut-out pressure of the pressure switches must be adjusted to the pressure relief valve according to specifications in the standards.
For this purpose, the adjustable pressure switch must be ordered as an option.

Which ECOSTAR condensing units are affected by the exchange of the frequency inverter and what changes for the customers?

In the models LHV7E, the suction gas cooled .F3 frequency inverters were replaced in 2023 by air cooled VARIPACK frequency inverters (model FOY+39-4, IP66). The model designation changes from LHV7E/ .. .F3 to LHV7E/ .. .F. Application limits, frequency ranges, refrigerating capacity etc. remain unchanged. From the outside, only the ventilation slot in the weather protective housing of the ECOSTAR is visible.
This change does not apply to ECOSTAR models with .F1 frequency inverter.
