Condensing Unit For Refrigeration Networks
Suction line connections
An adequately sized suction header providing equal distribution of returning refrigerant to
each condensing unit must be used. Suction type diameter at the rear of the unit is 1 3/8.

Liquid line
Each unit outlet liquid line should be connected to a liquid line header.
For low temperature system Copeland recommends to insulate liquid line to evaporator in
order get keep the sub-cooling effect from the heat exchanger.
Receiver equalization lines
Liquid equalization line to be connected between 2 receivers is on the middle
bottom of the unit.
Copper connection. Diameter 1 1/8.
Gas pressure equalization
Copper connection. Diameter 5/8.
Oil inlet and outlet
The oil distribution lines with Schraeder valves need to
be connected with flexible hoses
(Option proposed by Copeland).
2 unit Network back to back configuration:
Copeland recommends the 2 metres flexible
kit.
For 2 unit Network side by side configuration:
Copeland recommends 4 metres flexible kit.
Care
should be taken when connecting the hoses,
“oil in” of the master
unit should
connected the
to “oil out” of the slave
unit.
Communication cable
A communication cable with M12 connectors (option proposed by Copeland) needs to be
connected between units. A 4 metres cable is recommended for 2-unit network
configuration. If connection to a monitoring system is required, an additional cable is
needed.
