No additional charge of compressor oil is necessary.
* If the total tubing length exceeds 30 m, charge the amount of refrigerant as
shown above in "Required additional refrigerant" for every 1 m in excess of
30 m for outdoor units.
TWIN, TRIPLE AND DOUBLE TWIN TYPE CONNECTIONS
Two, three or four indoor units can be operated simultaneously with a single remote control unit. Note that individual operation is not possible.
Master unit and slave unit can be set automatically in twin and triple system.No address setting is necessary.

Use the main pipe to gain any rise or fall
required for the pipes.
•
The number of bends should be 8 or less in a
single system, and 15 or less overall.
•
Branch pipes should be positioned horizontally.

Refrigerant charging
For the twin/triple/double twin connection, the amount of refrigerant required for pipe length 30m has been included in this unit at the factory.
No additional charge is required for the fi rst 30m pipe length in those cases. The amount of included refrigerant for each model is listed
on NAME PLATE.
Make additional charges by adding up pipe length in an order of main pipe (L)
→
branch pipe (La
→
Lb
→
Lc wide diameter) and then selecting
the amount of refrigerant corresponding to the remaining (after 30m) liquid side pipe diameter and pipe
length from the below table.
