► VERY IMPORTANT – MACHINE SHUTDOWN ◄
The new SAE Standard J2788 dictates that the filter must be changed at
set intervals to ensure that recycled refrigerant is pure.
The RHS980 has one filter which must be changed after recycling every
150 lbs. of refrigerant.
The technician will be alerted when the filter life is at 100 LB (45 KG). This
allows time to order a replacement filter kit (See “Parts Identification”).
When the filter has purified 150 LB (68 KG) of refrigerant, the RHS980 will
shut down and not perform any function.
A new filter must be installed to re-activate the RHS980C-NAV controller.
OVERVIEW OF THE RHS980 AND HOW TO OPERATE IT
The RHS980 is designed for intuitive operation with menu driven prompts on the display.
A few minutes spent reviewing the contents of this operation manual will enable the technician to understand and
optimize the use of the RHS980 to provide customers with a professional A/C service.
The display shows data such as the internal cylinder weight and prompts the technician for input using the alpha-
numeric keypad and various navigation buttons.
The RHS980 can be used to perform a fully automatic A/C service. The technician will be prompted for entry of data
such as charge amount and given options like vacuum leak test. Once the necessary data has been entered, the
RHS980 will automatically perform the complete A/C service and alert the technician for interaction or that the
service is complete.
The RHS980 can also be used to perform individual functions like recycle, vacuum or charge. The keypad has
dedicated buttons (AUTOMATIC, RECYCLE, VACUUM and CHARGE) to allow the technician to jump directly to any
one of these functions.
Units of measure displayed can be changed at any time by repeatedly pressing the U/M key.
A setup routine can be used to select options, set default values, perform maintenance operations and manage fluid
capacities processed.
