►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.
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.
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 Technologies and providing information to one of the Technical Support Technicians.

STARTUP & SAFE OPERATION
9Do not use a damaged unit. Check for shipping damage and place a claim with carrier if
damage is discovered.
9Return the Warranty Card to activate technical support service and warranty coverage.
9The RHS980 should be operated by certified personnel only.
9The RHS980 should not be operated or serviced by any person who has not read all the
contents of this manual.
9This 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.
9It is the responsibility of the owner/user to operate the RHS980 in accordance with all laws
and specifications which may apply.
9Recover, recycle, and charge only R134a.
9Avoid breathing refrigerant or lubricant vapor. Exposure may irritate eyes, nose and throat.
Ventilate work area if accidental system discharge occurs.
9Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can
cause frostbite.
9Follow the RHS980 operating procedures sequentially to avoid prematurely disconnecting
hoses or opening valves which may release refrigerant to the atmosphere.
9Do not expose the RHS980 to moisture or operate in wet areas.
9Use the RHS980 in locations with ventilation that provides at least four air changes per hour.
9Service hoses must be constructed of the proper materials and should be of minimal length.
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.
9Avoid 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.
9Disconnect power before performing any maintenance or service on the RHS980.
9Do not connect the RHS980 to the liquid side of any A/C with a capacity greater than 4 lbs.
Refrigerant in A/C Systems having larger capacities must be recovered from the vapor side
only.
9
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.

Refrigerant will be transferred from the cylinder on the
rear platform into the internal charge cylinder of the
RHS980.
The amount transferred will be displayed.
The Fill Cylinder procedure is complete when
approximately 18 lbs. of refrigerant has been
transferred. The Setup procedure allows changing the
value and is covered elsewhere in this manual.
REFRIGERANT BLENDS
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 to be serviced.
Recovering other refrigerants will contaminate the refrigerant in the RHS980
charge cylinder.
LEAK SEALERS
Many sealants and leak stop chemicals are being injected into A/C systems.
These may cause serious damage to the RHS980 if they are in the refrigerant
recovered being recycled.
Detection devices are available to check for the presence of these chemicals
and are highly recommended to protect the RHS980.
The RHS980 may be damaged which could void the warranty.
Call RTI for more information about solutions for detection of refrigerant blends
and leak sealers.

COMBO FILTER MAINTENANCE
The RHS980 combo filter must be replaced after every
150 lbs. of refrigerant has been recovered from A/C
systems. An alert will display when the filter life is at
100 lbs. The RHS980 will shut down when the filter life
is at 150 lbs. A new filter must be installed and a serial
number entered to re-start the RHS980.
A special routine for changing the combo filter is
explained on Page 12.
The document pocket on the left side of the RHS980
can be removed to gain access to the combo filter.
The combo filter is on the right side of the manifold as
shown in the photo. A hex on top of the filter is
provided to make filter removal and installation easy.
Use an end wrench on this hex. New O-rings are
provided with the replacement filter.
A serial number is printed on a label attached to the
new filter. Make a note of this number as it may not be
visible when the filter is installed. This serial number
must be entered to reset the 150 hour filter life routine.
Order Filter Kit: 360-82133-00
The RHS980 records the hours the vacuum pump
runs. A reminder screen displays when that total
equals 10 hours. The vacuum pump oil should be
changed at that time. This screen displays the hours
remaining until the reminder screen will display. Press
START key to continue.
