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.

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.

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 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.

NOTICE: If doing a Manual Oil Injection, you must only charge refrigerant to the

high or both sides.

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

 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. 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.

 It is the responsibility of the owner/user to operate the RHS980 in accordance with all laws

and specifications which may apply.

 Recover, recycle, and charge only R134a.  Avoid breathing refrigerant or lubricant vapor. Exposure may irritate eyes, nose and throat.

Ventilate work area if accidental system discharge occurs.

 Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can

cause frostbite.

 Follow the RHS980 operating procedures sequentially to avoid prematurely disconnecting

hoses or opening valves which may release refrigerant to the atmosphere.

 Do not expose the RHS980 to moisture or operate in wet areas.  Use RHS980 in areas with ventilation that provides at least four air changes per hour.  Service hoses must be constructed of the proper materials and with lengths as supplied with

the RHS980 (See “Parts Identification”). 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.

 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.

 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.

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. Refer to SETUP section under DEFAULT VALUES to change the factory setting. Connect the short yellow hose on the rear of the RHS980 to a new 30 lb. cylinder of refrigerant. Open the cylinder valve, turn the cylinder up-side-down and place it on the platform. Secure with web belt.

Plug the power cord into an appropriate power source. Avoid using an extension cord. If necessary, use a good condition, three wire grounded, #14 AWG or larger extension cord of the shortest possible length.

Sample of new cylinder refrigerant is processed and the hose and coupler must be removed. Press START key.

This shows the results from the refrigerant sample processed. Select NO key to reject these results or YES key to accept the results. Pressing NO will return to the initial screen.

If the results from the refrigerant identification show an air percentage above 5%, this screen will appear. Inspect the id filter, sample hose and coupler filter prior to the next identification to ensure these devices are free of oil contamination. See REFRIGERANT IDENTIFIER MAINTENANCE section for more information.

This is a reminder that the cylinder of new refrigerant must be connected to the yellow hose on the rear of the RHS980. Press START key.

Refrigerant will be transferred from the cylinder on the rear platform into the internal charge cylinder of the RHS980. Cylinder of new refrigerant must be upside down with valve at bottom of tank.

The amount transferred will be displayed.

Note: Pressing the STOP key will start an internal clearing process. This process must run to completion to remove internal refrigerant.

The RHS980 is designed to recover, recycle and charge R134a. Take extreme precaution to ensure that other refrigerants are not recovered into the RHS980.

A refrigerant identifier is recommended for evaluating refrigerant in the A/C system prior to servicing.

Recovering other refrigerants will contaminate the refrigerant in the RHS980 charge cylinder.

Sealants and leak stop chemicals in A/C systems may cause serious damage to the RHS980 if they are present in the refrigerant recovered intended for recovery.

Detection devices are readily available to check for the presence of these chemicals and are highly recommended to protect the RHS980.

REFRIGERANT BLENDS

LEAK SEALERS

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.

Note: To fill to less than 18 LB (8.16 KG), close valve on cylinder of new refrigerant and allow procedure to complete. A minimum of 10 LB (4.53 KG) is suggested for truck service application. Do not manually STOP process with out allowing the RHS980 to clear the refrigerant from the accumulator.

Call RTI for more information about solutions for detection of refrigerant blends and leak sealers.

AUTOMATIC OPERATION

The AUTOMATIC function allows an operator to program an automatic recycle, vacuum, vacuum leak test and charge sequence.
