FIRST TIME USE The first time a new RHS980 is turned on it will automatically perform a routine where the language is selected. The language can be changed later if desired in the Setup Mode. The RHS980 will arrive without any refrigerant. It will be necessary to put new refrigerant into the internal charge cylinder before any other sequences can be run. The amount of refrigerant which must be transferred is factory set at 18 lbs. Connect the short yellow hose on the rear of the RHS980 to a new 30 lb.
Refrigerant will be transferred from the cylinder on the rear platform into the internal charge cylinder of the RHS980.
