4.9.6 Version LC: remote condenser above the evaporating unit:
a) Make a trap on the supply line, immediately downstream from the compressor, to collect the liquid refrigerant
which can develop during unit shutdown and could irreparably damage the compressor.
b) Install siphons at least every 6 metres on vertical upward sections of pipelines in order to facilitate the return of
oil to the compressor.
c) Ensure that there is a gradient of at least 1% on horizontal sections of the refrigerant lines to facilitate oil
drainage in the correct direction of the flow.
d) Install a non return valve close to condenser inlet, to avoid liquid refrigerant entering the compressor during unit
shutdown. This must be done with the unit off and when the ambient temperature of the condenser is higher
than that of the compressor.

4.9.7 Version LC: remote air cooled condenser below the evaporating unit:
There are no special suggestions for this installation.
It is however advisable to install a non return valve close to the compressor inlet, to avoid liquid refrigerant
entering the compressor during unit shutdown. This must be done with the unit off and when the ambient
temperature of the condenser is higher than that of the compressor.
