SAFETY PRECAUTIONS
! Recover, Recycle, and Charge only the refrigerant for which the machine is configured.
! Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and
can cause frostbite.
! Follow the RRC770 operating procedures sequentially to avoid prematurely
disconnecting hoses or opening valves which may release refrigerant to the
atmosphere.
! Do not expose the RRC770 to moisture or operate in wet areas.
! Use the RRC770 in locations with mechanical ventilation that provides at least four air
changes per hour.
! Hoses used with the RRC770 must have shutoff devices within 12 inches of the
connection point to the system being serviced to minimize the introduction of Non-
condensable Gas (Air) into the RRC770 and the release of refrigerant when being
disconnected.
! Disconnect power before performing any maintenance or service on the RRC770.
! Avoid using an extension cord with the RRC770. If necessary, use a good condition,
UL listed, 3-wire grounded, #14 AWG extension cord of the shortest possible length.
Connect the RRC770 to a properly protected, grounded receptacle. Do not over load
the circuit.
! Do not allow the RRC770 to remain unattended in the Charge Mode with power On.
The Internal Cylinder Heater will be energized creating a high pressure condition.
NEVER TURN THE CYLINDER UP-SIDE-DOWN.
DO NOT CONNECT THE RRC770 TO THE LIQUID SIDE OF ANY
A/C SYSTEM WITH A CAPACITY GREATER THAN 4 LBS.
REFRIGERANT IN A/C SYSTEMS HAVING LARGER CAPACITIES
MUST BE RECOVERED FROM THE VAPOR SIDE ONLY.
NEVER CONNECT THE RRC770 TO THE LIQUID PORT OF A
CYLINDER OF REFRIGERANT TO FILL THE RRC770 INTERNAL
CYLINDER.
FAILURE TO FOLLOW THE ABOVE MAY CAUSE THE RRC770
COMPRESSOR TO FAIL AND VOID THE WARRANTY.
