6.7.3 LE version: unit installed at a lower level than the remote exchanger
Fit a syphon on the highest suction line "G" of the evaporator in order to prevent liquid refrigerant from going towards the
compressor when the unit is not running.
In the horizontal sections of the suction line "G", it is advisable to have a slope of at least 1% to facilitate oil return to the
compressor.
6.7.4 LE/HP version: unit installed at a higher level than the remote exchanger
There must be syphons on the vertical sections of the suction/delivery line "G" to facilitate oil return to the compressor. The
height "h" must be less than 4 metres.
The horizontal sections of the suction/delivery line "G" must not slope at all.
