7.22. For the PKE and PKE CO2 condensers, install the anti-vibration device and the silencer on the delivery line
between the compressor and the condenser.
7.23. For installations at height use lifting platforms, portable or fixed scaffolding.
7.24. To protect against indirect contacts, the installer must provide a differential switch upstream of the machine
panel with adequate electrical characteristics (value in A referring to the electrical data of the installed fans, see
point 0 or label on the fan).
7.25. On request, the models can be supplied with exchangers and fan motors other than the standard.
