INTRODUCTION RTI RHS980 Refrigerant Handling System is designed for use on R134a vehicles and is compliant with J2788 standard. Unit recovers 95% of automobile refrigerant systems and has a refrigerant recharge accuracy of +/- ½ ounce. It features fully automatic operation. All control functions of the RHS980 are designed to provide intuitive and rapid interaction with the service technician.
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 alphanumeric keypad and various navigation buttons.
STARTUP & SAFE OPERATION Do not use a damaged unit. Check for shipping damage and place a claim with carrier if damage is discovered. Return the Warranty Card to activate technical support service and warranty coverage. The RHS980 should be operated by certified personnel only. The RHS980 should not be operated or serviced by any person who has not read all the contents of this manual. This manual describes normal operation and maintenance for the RHS980.

The alpha-numeric keypad is used to enter data when prompted on the LCD screen.
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.

If oil is present in the hose, remove the contaminated hose section or replace the entire hose assembly. See REFRIGERANT IDENTIFIER MAINTENANCE section of manual. Press START key.
The Fill Cylinder procedure is complete when desired amount of refrigerant has been transferred. The Setup procedure allows changing the value and is covered in DEFAULT VALUES section in this manual.

A minimum of 10 LB (4.53 KG) is suggested for truck service application.
AUTOMATIC OPERATION The AUTOMATIC function allows an operator to program an automatic recycle, vacuum, vacuum leak test and charge sequence.

Press YES key if you want to inject oil into the A/C system after the Vacuum process has been completed. After the vacuum process has been completed the RHS980 will prompt you to inject the desired amount of oil. Selecting oil injection will only allow charging refrigerant to the high side or both sides. Press NO key if no oil is to be injected into the A/C system. If the RHS980 unit is enabled for the HYBRID OIL FLUSH feature, the RHS980 will not allow you to inject oil into the A/C system.

VACUUM PUMP MAINTENANCE Fill Port Oil must be periodically changed in the vacuum pump to ensure continued performance. The RHS980 will display a reminder after every ten hours of vacuum pump use. A drain port and fill port for the vacuum pump protrude through the rear wall of the RHS980 to the left of the handle. A sight glass for viewing the oil level in the vacuum pump is located on the end of the fill port. Remove Fill Port Cap to optimize fluid draining.
INLINE FILTER MAINTENANCE It is recommended that the inline filter elements be changed at a minimum of every 75 lbs of processed refrigerant. 1. Pressure gauges must read zero or less. If not, perform a recycle procedure. 2. Remove the red and blue service hoses from the connection ports on the rear of the RHS980. 3. Use a deep 5/8 inch socket on the hose connection fitting along with a 5/8 inch backing wrench to remove the filter element housing (as shown to right). 4.
PRINTER MAINTENANCE (Optional Item) The printer paper will require replacement and can be accessed on the rear of the RHS980. Paper is 58MM Wide X 45MM Diameter Thermal paper and can be found at most local office supply retailers. Replacement paper is available from RTI. Order Kit: 360 82218 00 Press the door release button to open cover as shown. Insert the paper with about 5mm of paper outside the printer. Close cover door. Light will indicate Green when printer is ready.
UPDATING PROGRAM, LANGUAGES AND AC DATABASE The RHS980 has the capability to easily update program functionality, screen languages and AC charge capacity database. This is accomplished by inserting a programmed flash drive into the USB slot in the rear of the unit and cycling power OFF and ON.
