Suction Header
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.

Unit
The non-symmetrical design as shown is acceptable and does not create oil level
problems between units.
Liquid line from receiver to Heat Exchanger (for low temperature networks)
Each condensing unit needs to be connected to the liquid receiver to supply liquid to heat
exchanger.
A copper pipe of 1 1/8” needs to be connected from the receiver to each heat exchanger.
Liquid line from Heat Exchanger (for low temperature networks)
The liquid outlet line from the heat exchanger to the system (to evaporators) needs to be
insulated.
Liquid outlet diameter is 5/8.
Oil inlet and outlet
The oil distribution lines with Schraeder valves need to be connected with flexible hoses
(option proposed by Copeland).
Care
should be taken when connecting the hoses,
“oil in” of the master
unit should
connected the
to “oil out” of the slave
unit.
Flexible hoses kit of 0.5 metres
could be connected to a copper line
of ¼”.
Communication cable
2 communication cables with M12 connectors (option proposed by Copeland) need to be
connected between units.
It is possible to add a cable to close the communication network and insure back up when
communication fails between master and the slave 1. In this configuration 3 kits will be
needed. If connection to a monitoring system is required, an additional cable is needed.
