•
W0 is outdoor unit refrigerant charge before shipment.
•
In case of the combination of the base units, calculate the
total refrigerant charge before shipment of the outdoor units
to be combined.
Regarding the fluorocarbon, follow the specification label or re
-
frigerant label attached to the product. After the additional re
-
frigerant charge, record the total refrigerant (= refrigerant before
shipment + additional refrigerant in the field) in the refrigerant
label (*).
(*): In case of the combination of base units, record the total re
-
frigerant in the main unit label.
N O T E
When the refrigerant is recovered or charged because of
repairing, operating or adjusting the unit, record the refrigerant
quantity again.

• For disposal and maintenance of this product, collection of
fluorocarbons is required.
Additional refrigerant calculation for wall type
(RPK-FSNH3M Series) with the expansion valve kit
The additional refrigerant calculation for wall type (RPK-FSNH3M
Series) with the expansion valve kit is as follows. Refer to the
item
Calculating method of additional refrigerant charge W1
.
Firstly calculate the additional refrigerant amount for the liquid
pipe between Multi-Kit and the expansion valve kit according to
the piping length and diameter.
Then, calculate the additional refrigerant amount for the liquid
