INTRODUCTION RTI RHS980C 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 RHS980C are designed to provide intuitive and rapid interaction with the service technician.
OVERVIEW OF THE RHS980C AND HOW TO OPERATE IT The RHS980C 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 RHS980C 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 RHS980C should be operated by certified personnel only. The RHS980C 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 RHS980C.

FIRST TIME USE The first time a new RHS980C 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 RHS980C 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.

HIGH PRESSURE LEAK DETECT HIGH PRESSURE LEAK DETECT allows an operator to pressurize a component or system to detect a difficult to locate leak prior to checking with an external leak detector. Recommend to start process with an internal system capacity of 8 to 10 LB (3.63 to 4.54 KG). Use of a leak detector meeting newest standard SAE J2791 or later is suggested.

HIGH VOLTAGE OIL FLUSH The RHS980C can be configured from the factory to have the ability to perform an internal oil flushing process to eliminate cross contaminations between PAG oil used in a conventional R-134a system and POE oil used in HIGH VOLTAGE HYBRID systems. The POE oil acts as a lubricant, but more importantly the POE oil is required to keep the HIGH VOLTAGE system isolated from the chassis. If the HYBRID’s system becomes conductive, the service technician can be at risk of electrical shock.

VACUUM PUMP MAINTENANCE Oil must be periodically changed in the vacuum pump to ensure continued performance. The RHS980C will display a reminder after every ten hours of vacuum pump use. Fill Port A drain port and fill port for the vacuum pump protrude through the rear wall of the RHS980C 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 RHS980C. 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 RHS980C. 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.
