IMPORTANT! THE ONLY ACCEPTIBLE METHOD TO CHARGE THE J-II SYSTEM
IS BY WEIGHING IN THE ADDITIONAL REFRIGERANT!
CHARGE CALCULATION IS BASED UPON THE TOTAL LIQUID LINE LENGTH USED
R-410A ONLY! NO ALTERNATE REFRIGERANT USE IS PERMITTED!
ADD REFRIGERANT INTO LIQUIU LINE ONLY!
NOTE: OPEN SERIVCE VALVES ONLY AFTER WEIGHING IN ADDITIONAL REFRIGERANT
If power was turned ON to the indoor unit(s) at any time prior to evacuation,
the indoor unit electronic expansion valve (EEV) will close and inhibit system
evacuation. In order to reopen the IU unit EEV’s:
Turn power ON to outdoor unit and indoor units.
Press the "MODE/EXIT" button on the OD unit control board.
Use the “SELECT” button to scroll to function F3.
Press the "ENTER" button.
Use the “SELECT” button to scroll to item code "21"
Push and HOLD the "ENTER" button for about 5 seconds.
Turn power OFF to all units when "PoFF" is displayed.
Perform system evacuation.
You may also use these instructions to recover refrigerant if necessary.
