OVERVIEW OF THE RHS980 AND HOW TO OPERATE IT
The RHS980 is designed for intuitive operation with menu driven prompts on the display.
However, 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 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 such as 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 such as 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, check calibration and manage refrigerant and oil.
IMPORTANT – review the Startup & Safe Operation statements on the following page before operating the RHS980.
Failure to do so may cause personal injury or cause the RHS980 to malfunction.
The Automatic Mode of operation is explained in the following pages. The screen which will be displayed for each
step is shown on the left. A description of the RHS980 operation is shown to the right of each screen.
► 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 lbs. This
allows time to order a replacement filter kit (P/N 360-82133-00).
When the filter has purified 150 lbs. of refrigerant, the RHS980 will shut
down and not perform any function.
A new filter must be installed to re-activate the RHS980 controller.
Fill out and return the Warranty Registration to activate the RHS980 warranty and free lifetime technical support. This
can also be done by calling RTI and providing information to one of the Technical Support Technicians.

STARTUP & SAFE OPERATION
9 Do not use a damaged unit. Check for shipping damage and place a claim with carrier if
damage is discovered.
9 Return the Warranty Card to activate technical support service and warranty coverage.
9 The RHS980 should be operated by certified personnel only.
9 The RHS980 should not be operated or serviced by any person who has not read all the
contents of this manual.
9 This manual describes normal operation and maintenance for the RHS980. Failure to read
and comply with these instructions or any one of the limitations noted herein can result in
serious injury and/or property damage. The instructions should not be interpreted to anticipate
every possible contingency.
9 It is the responsibility of the owner/user to operate the RHS980 in accordance with all laws
and specifications which may apply.
9 Recover, recycle, and charge only R134a.
9 Avoid breathing refrigerant or lubricant vapor. Exposure may irritate eyes, nose and throat.
Ventilate work area if accidental system discharge occurs.
9 Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can
cause frostbite.
9 Follow the RHS980 operating procedures sequentially to avoid prematurely disconnecting
hoses or opening valves which may release refrigerant to the atmosphere.
9 Do not expose the RHS980 to moisture or operate in wet areas.
9 Use the RHS980 in locations with ventilation that provides at least four air changes per hour.
9 Service hoses must be constructed of the proper materials and with lengths as supplied with
the RHS980. Replacement hoses: Red = P/N 028-80035-04 and Blue = P/N 028-80036-04.
Hoses must have shutoff devices at the connection point to the A/C to minimize the
introduction of air into the RHS980 and the release of refrigerant when being disconnected.
9 Avoid using an extension cord with the RHS980. If necessary use a good condition, three wire
grounded, #14 AWG or larger extension cord of the shortest possible length.
9 Disconnect power before performing any maintenance or service on the RHS980.
SPECIAL CONSIDERATIONS WITH R134a
R134a has been shown to be nonflammable at ambient temperature and atmospheric pressure.
However, tests under controlled conditions have indicated that at pressures above atmospheric
and with air concentrations greater than 60 percent by volume, R134a can form combustible
mixtures.
While it is recognized that an ignition source is also required for combustion to occur, the
presence of combustible mixtures is a potentially dangerous situation and should be avoided.
Under no circumstances should any equipment be pressure tested or leak tested with air and
R134a mixtures. Do not use compressed air for leak detection in R134a systems.
