CONGRATULATIONS
THANKS
Performing these tests demonstrated that the RHS780 is operating correctly.
NOW IT’S TIME TO MAKE SOME MONEY
The best suggestion we can offer is that you quickly browse the Operation Manual before using
the RHS780 to perform an actual A/C service. Then, during the first few uses, refer to the
Operation Manual and follow the instructions as each process is performed.
The RHS780 was carefully designed to be intuitive to use. The display screens prompt for input
as required and always ask for confirmation before starting a process.
It’s very important that you follow the Operation Manual the first few times to become familiar with
the techniques of using the RHS780 for A/C service. Then you will find that the display screens
will give you adequate prompts for future use.
