Calculating the quantity of refrigerant to add
The quantity of additional refrigerant is variable according
to the installation situation. Thus, make sure the outdoor
unit situation before adding refrigerant.
If you install the excessive length of pipe, add additional
refrigerant as 10g or 20g per unit meter ; refer to the table
below.
Refer to the Service Manual for more details on this
operation.

CAUTION
•
The filled-out label must be adhered in the proximity
of the product charging port (e.g. onto the inside of the
stop valve cover).
•
Make sure that the total refrigerant charge does not
exceed (
A
), the maximum refrigerant charge, which
is calculated in the following formula: Maximum
refrigerant charge (
A
)= factory refrigerant charge (
B
) +
maximum additional refrigerant charge due to piping
extension (

).

Step 11 Connecting the drain hose to
the outdoor unit
When heating, ice may accumulate. During the process of
defrosting, check if condensation draining is adequate.
For adequate draining, do the following :
1
Insert the drain plug into the drain hole on the
underside of the outdoor unit.
2
Connect the drain hose to the drain plug.
3
Ensure that condensation draining is adequate.
4
Be sure to plug the rest of drain holes not connected
with drain plugs using drain caps.
•
When installing the product, make sure that the
rack is not placed under the drain hole.
•
If the product is installed in a region of heavy snow,
allow enough separation distance between the
product and the ground.
