Refrigerant for the extended piping is not included in the outdoor unit when the unit is
shipped from the factory. Therefore, charge each refrigerant piping system with addi-
tional refrigerant at the installation site. In addition, in order to carry out service, enter
the size and length of each liquid pipe and additional refrigerant charge amounts in
the spaces provided on the "Refrigerant amount" plate on the outdoor unit.

(For example, if the calculated charge is 6.01 kg, round up the charge to 6.1 kg.)
Outdoor unit drainage pipe connection
When drain piping is necessary, use the drain socket or the drain pan (option).

1 Follow ordinance of your governmental organization for technical standard related
to electrical equipment, wiring regulations and guidance of each electric power
company.
2 Wiring for control (hereinafter referred to as transmission line) shall be (5 cm or
from power source wiring. (Do not insert transmission line and power source wire
in the same conduit.)
3 Be sure to provide designated grounding work to outdoor unit.
4 Give some allowance to wiring for electrical part box of indoor and outdoor units,
because the box is sometimes removed at the time of service work.
5

6
systems are wired with the same multiplecore cable, the resultant poor transmit-

different refrigerant systems, the control line for transmission is required between
the outdoor units each other.
Connect this control line between the terminal blocks for centralized control. (2-

When conducting group operation in different refrigerant systems without connect-
ing to the upper class controller, replace the insertion of the short circuit connector
