6.6.8 LC version: unit installed at a lower level than the remote exchanger
A summary is given below of the measures to be taken if the unit is installed at a lower level than the condenser:
make a well on the delivery line just downline of the compressor to collect the liquid refrigerant that can form during the
stops of the unit and can irreparably damage the compressor;
- there must be syphons on the vertical sections of the delivery line "G" to facilitate oil return to the compressor. The hei-
ght "h" must be less than 4 metres;
- in the horizontal sections of the delivery line "G", make a slope of at least 1% to facilitate oil return to the compressor;
- install a non-return valve near the condenser inlet in order to prevent liquid refrigerant from returning to the compressor
when the unit is not running.
6.6.9 LC version: unit installed at a higher level than the remote exchanger
A summary is given below of the measures to be taken if the unit is installed at a higher level than the condenser:
- install a non-return valve near the condenser inlet in order to prevent liquid refrigerant from returning to the compressor
when the unit is not running if the condenser is situated in an environment that may be at a higher temperature than the
compressor;
- in the horizontal sections of the delivery line "G", it is advisable to have a slope of at least 1% in the direction of refri-
gerant gas outflow to aid oil return.
