REFRIGERANT FLUSH

REFRIGERANT FLUSH will force liquid refrigerant in a reverse flow through a component or components to
remove contaminates and oil. Special flush components and adapters are available through RTI to properly
connect to standard AC components.

Enter the desired time to flush using the alphanumeric
keypad. Press START key to continue.

Empty oil bottle and adjust o-ring. Press START key to
continue.

Following adapter detailed installation instructions,
connect flush filter and service couplers to AC
component. Press START key to continue.

The RHS980C will pulse charge liquid and recycle
refrigerant through the component being serviced.
Contaminants will be captured in the service filter.
Press the STOP key to abort the operation.

Observe pressure shown on pressure gauges and if
pressure is less than 0 psi, carefully remove
connections from component under test. If pressure is
greater than 0 psi, perform a recycle before
disconnecting component. Press START key to
continue.

Check the oil bottle and empty if required. Flush filter
must be replaced after every service. Press START
key to continue.

Since refrigerant flushing removes all oil from the
component being serviced, ensure that the proper
quantity of oil is manually replenished.

If system states “CHARGE FAILED”, check flush

filter, component or system for blockage.
