CONVERTIBLE

RECYCLING MACHINE

This Recycling Machine was

manufactured by RTI in compliance
with all applicable Underwriters
Laboratories (UL) and Society of
Automotive Engineers (SAE)
Standards and Specifications for
Refrigerant Recycling Equipment.

Your machine is initially configured

to recycle R12 or R134a.

An RTI Retrofit Kit is available for

field conversion of this machine to
recycle the alternate refrigerant for
which it is now configured. This kit
includes complete instructions, labels,
filters, hoses with service couplers, and
special tools required to make the
conversion.

Once converted by an RTI Authorized

Representative, a new Serial Label
(included in the kit) will be affixed to
the machine. This Serial Label will
certify that the machine is then in
compliance with all SAE and UL
Standards and Specifications for
Equipment to recycle the alternate
refrigerant.

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 operati ng 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 ne cessary, 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 cir cuit.
! Do not allow the TC670 to remain unattended in the Charge Mode with power On. Th e Charg e

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.
