The refrigerant is pre-charged in the outdoor unit. If the piping length is less than 25ft (7.6m), then additional charge after
vacuuming is not necessary. If the piping length is more than 25ft (7.6m), then use the additional charge value as indicated
in the table.
Additional refrigerant charge [oz (g)] per additional 3.28ft (1m) length as tabulated.

Outdoor
Additional charge [oz/ft (g/m)]
Example:
FTXK09 & RXK09 with 39.4ft (12m) piping length, additional piping length is 14.4ft (4.4m).
Thus, Additional charge = 14.4ft (4.4m)x 0.21oz/ft [20g/m]
= 3.024oz [88.0g]

The table shows the LED indicator lights for the air
conditioner unit under normal operation and fault conditions.
The LED indicator lights are located at the side of the air
conditioner unit.
The heat pump units are equipped with an "auto" mode
sensor whereby it will provide reasonable room temperature
by switching automatically to either "cool" or "heat" mode
according to the temperature set by the user.
