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 (C).
• Here below, the summary table with refrigerant
charge limits for each products.

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.
