HIGH VOLTAGE OIL FLUSH
An RHS980 configured from the factory to perform service on high voltage systems is designated RHS980H.
The RHS980H has 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. During the HIGH VOLTAGE OIL FLUSH process the residual
PAG oil from previous services will be flushed from the HIGH - Low side couplers and hoses along with the
corresponding internal passages of the RHS980H unit.
IMPORTANT – THE HIGH VOLTAGE OIL FLUSH PROCESS MUST BE PERFORMED
BEFORE A SERVICE ON A HYBRID VEHICLE IS CONDUCTED!
IT IS THE SERVICE TECHNICIANS RESPONSIBILITY TO UNDERSTAND THE RISKS
INVOLVED IN SERVICING A HIGH VOLTAGE HYBRID A/C SYSTEM, AS WELL AS
DETERMING THE PROPER OIL REQUIRED FOR THE HYBRIDS A/C SYSTEM TO ENSURE
ITS ELECTRICAL ISOLATION FROM THE VEHICLES CHASSIS IS MAINTAINED.
Units that are configured for the High Voltage Oil Flush, there will be a screen illustrated below that will start
the High Voltage Oil Flush process, as well the RHS980H will NOT have the oil injection feature. The oil
injection bottle and connections will NOT be present next to the oil drain bottle. The High Voltage Oil Flush
configured unit will also be shipped with a HIGH -LOW side adapter so that the hoses can be connected to
flush residual PAG oil from previous services. To access to the HIGH VOLTAGE OIL FLUSH FEATURE, follow
the procedure below.
