Oil distribution circuit Communication cable
Liquid pipe to evaporator(s)
Suction pipe from evaporator(s)
Low Temperature Network
+/- 4900 mm

Low temperature networks need additional piping between each unit heat exchanger and
the receiver, in order to get liquid for vapour injection.
IMPORTANT
For low temperature network systems, Copeland recommends to insulate the complete
liquid outlet line to the expansion valve in order to optimise the sub-cooling effect.
