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 TC670 operating procedures sequentially to avoid prematurely disconnecting hoses
or opening valves which may release refrigerant to the atmosphere.
! Do not expose the TC670 to moisture or operate in wet areas.
! Use the TC670 in locations with mechanical ventilation that provides at least four air changes
per hour.
! Hoses used with the TC670 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 TC670 and the release of refrigerant when being disconnected.
! Disconnect power before performing any maintenance or service on the TC670.
! Avoid using an extension cord with the TC670. If necessary, use a good condition, UL listed,
3-wire grounded, #14 AWG extension cord of the shortest possible length.
! Connect the TC670 to a properly protected, grounded receptacle. Do not over load the circuit.
! Do not allow the TC670 to remain unattended in the Charge Mode with power On. The Charge
Cylinder Heater will be energized creating a high pressure condition.
NEVER TURN THE CYLINDER UP-SIDE-DOWN.
DO NOT CONNECT THE TC670 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 TC670 TO THE LIQUID PORT OF A
CYLINDER OF REFRIGERANT TO FILL THE TC670 CHARGE CYLINDER.
FAILURE TO FOLLOW THE ABOVE MAY CAUSE THE TC670 COMPRESSOR TO
FAIL AND VOID THE WARRANTY.
