FIRST TIME USE
The first time a new RHS980 is powered up 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 to be transferred is factory set at 18
LB (8.16 KG). This amount can be adjusted if desired. Refer to SETUP section under DEFAULT VALUES to change
the factory setting. Connect the short yellow hose on the rear of the RHS980 to a new 30 lb. cylinder of refrigerant.
Open the cylinder valve, turn the cylinder up-side-down and place it on the platform. Secure with web belt.
Plug the power cord into an appropriate power source. Avoid using an extension cord. If necessary, use a good
condition, three wire grounded, #14 AWG or larger extension cord of the shortest possible length.
