Determine the amount of refrigerant to be added by refer-
ring to the table, write it down on the included “Added
Refrigerant” plate and attach it to the rear side of the front
cover.
Note: Refer to Section 6-3,

___.for the amount to be added.
1. After the vacuum drying is finished, charge the addi-
tional refrigerant in its liquid state through the liquid stop
valve service port. You must then take the following
steps: Check that gas and liquid stop valves are closed.
2. Stop the compressor and charge the specified weight of
refrigerant.
•
If the outdoor unit is not in operation and the total amount
cannot be charged, follow the procedures for additional
refrigerant charge shown below.
•
Make sure to use installation tools you exclusively use on
R-410A installations to withstand the pressure and to pre-
vent foreign materials from mixing into the system.
Procedures for charging additional refrigerant
are as follows:.

Additional refrigerant charge procedures are as follows:
To learn the system settings for additional refrigerant charg-
ing, refer to the [Service Precaution] label attached on the
back of the electric box lid in the outdoor unit.
1. Fully open the gas-line stop valve but the liquid line stop
valve and valve A above must be left fully closed. Start
the additional refrigerant charge operation.
2. After the system is charged with a specified amount of
refrigerant, press the confirmation button (BS3) on the
P-board (A1P) in the outdoor unit to stop the additional
refrigerant charge operation.
3. Immediately restore the stop valve to the following sta-
tus. The test operation cannot be performed properly if
the stop valve is not correct.
Multiple Outdoor Units Installed:Refer to figure 12
To learn the system settings for additional refrigerant charg-
ing, refer to the
Service Precaution label attached on the
back of the electric box lid in the outdoor unit.
Use the following procedure to add additional refrigerant
charge:
1. Fully open the gas line stop valve/oil-equalizing line stop
valve (liquid line stop valve and valves A and B above
must be left fully closed), and begin the additional refrig-
erant charge operation.
2. After the system is charged with a specified amount of
refrigerant, press the confirmation button (BS3) on the
P-board (A1P) in the outdoor unit to stop the additional
refrigerant charge operation.
3. Immediately restore the stop valve to the following sta-
tus as a test operation cannot be performed properly if
the stop valve is not correct:
NOTE
If the refrigerant cylinder is siphonal, set it upright while
charging additional refrigerant.
7. FIELD WIRING
NOTE
•
All field wiring and components must be installed by a
licensed electrician and must comply with relevant local
and national regulations.
•
The field wiring must be carried out in accordance with the
following wiring diagrams and the instructions given below.
•
Be sure to use a dedicated power circuit. Never use a
power supply shared by another appliance.
•
This product’s reversed phase protection detector only
works when the product started up.
•
The reversed phase protection detector is designed to stop
the product in the event of an abnormalities when the prod-
uct is started up.
•
Replace two of the three phases (L1, L2, and L3) during
reverse-phase protection circuit operation.
•
Reversed phase detection is not performed while the prod-
uct is operating.
•
If there exists the possibility of reversed phase after an
momentary black out and the power goes on and off while
the product is operating, attach a reversed phase protec-
tion circuit locally. Running the product in reversed phase
can break the compressor and other parts.
There is a siphon tube
inside, so there is no need
to turn the tank upside-down.
Fill with the tank upright.
Fill with the tank upside-down.
