SAFETY PRECAUTIONS
! Recover 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 TC640 operating procedures sequentially to avoid prematurely
disconnecting hoses or opening valves which may release refrigerant to the
atmosphere.
! Do not expose the TC640 to moisture or operate in wet areas.
! Use the TC640 in locations with forced ventilation that provides four air
changes per hour.
! Hoses used with the TC640 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 TC640 and the release of refrigerant
when being disconnected.
! Disconnect power before performing any maintenance or service on the
TC640.
! Avoid using an extension cord with the TC640. If necessary, use a good
condition, UL listed, 3-wire grounded, #14 AWG extension cord of the
shortest possible length.
! Connect the TC640 to the proper, grounded power source of sufficient
amperage.
! Do not allow the TC640 to remain unattended in the Charge Mode with power
On.
NEVER TURN THE CYLINDER UP-SIDE-DOWN.
DO NOT CONNECT THE TC640 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 TC640 TO THE LIQUID PORT OF A
CYLINDER OF REFRIGERANT TO FILL THE TC640 CHARGE
CYLINDER.
FAILURE TO FOLLOW THE ABOVE MAY CAUSE THE TC640 COMPRESSOR TO FAIL
AND VOID THE WARRANTY.
