In systems with multiple outdoor units, the units
should be placed in order from largest capacity
unit to smallest capacity unit. The largest
capacity unit must be placed on the first branch,
and be set as the master unit, while the others
should be set as slave units. The capacity of
outdoor units A, B and C must meet the following

The piping between the outdoor units must be level or
slightly upwards.
The piping connecting the outdoor units should be
horizontal and must not be higher than the refrigerant
outlets. If necessary, to avoid obstacles the piping
may be vertically offset below the outlets. When
inserting a vertical offset to avoid an obstacle, the
whole outdoor piping should be offset, rather than just
the section adjacent to the obstacle.

short circuit capacity (of the power supply), Ssc, is
greater than or equal to the minimum Ssc value of the
interface point between the user’s power supply and the
public system.
The installation personnel or users have the
responsibility to consult the distribution network
operators when necessary to ensure that the equipment
only connects to a power supply with short circuit
capacity, Ssc, greater than or equal to the minimum Ssc
value.
