TC670E

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.

START-UP INSTRUCTIONS

1) Check for any shipping damage. Place a claim with carrier if damage is discovered.

2) Complete and return the Warranty Card to activate Technical Support and Warranty Coverage.

Warranty claims can not be honored without this warranty card on file.

BEFORE USING THE TC670E

Check for any shipping damage. Place a claim with carrier if damage is discovered.

DO NOT USE A DAMAGED UNIT.

Complete and return the Warranty Card to activate technical support service and warranty coverage.

Warranty claims can not be honored without this warranty card on file.

The TC670E should not be operated or serviced by any person who has not read all the contents of
this manual. Failure to read and comply with these instructions or any one of the limitations noted
herein can result in serious injury and/or property damage.

These general instructions describe normal operation and maintenance situations encountered with
the TC670E. The instructions should not be interpreted to anticipate every possible contingency.

It is the responsibility of the owner/user to operate the TC670E in accordance with all specifications
and laws which may apply.

The following pages contain rules for safe operation of the TC670E. Taking precedence over any
specified rule listed herein, however, is the most important rule of all:

"USE COMMON SENSE"

A few minutes spent reading these instructions can make an operator aware of dangerous practices
to avoid and precautions to take for his own safety and the safety of others.

A regular schedule of inspection of the TC670E should be established and records maintained with
special attention given to Hoses, Compressor Oil Level and Filters.

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 TC670E operating procedures sequentially to avoid prematurely disconnecting hoses

or opening valves which may release refrigerant to the atmosphere.

! Do not expose the TC670E to moisture or operate in wet areas.
! Use the TC670E in locations with mechanical ventilation that provides at least four air changes

per hour.

! Hoses used with the TC670E 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 TC670E and the release of refrigerant when being disconnected.

! Disconnect power before performing any maintenance or service on the TC670E.
! Avoid using an extension cord with the TC670E. If necessary, use a good condition, UL listed,

3-wire grounded, #14 AWG extension cord of the shortest possible length.

! Connect the TC670E to a properly protected, grounded receptacle. Do not over load the circuit.
! Do not allow the TC670E 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 TC670E 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 TC670E TO THE LIQUID PORT OF A

CYLINDER OF REFRIGERANT TO FILL THE TC670E CHARGE CYLINDER.

FAILURE TO FOLLOW THE ABOVE MAY CAUSE THE TC670E COMPRESSOR TO
FAIL AND VOID THE WARRANTY.

Avoid breathing refrigerant or lubricant vapor or mist.

Exposure may irritate eyes, nose and throat.

If accidental system discharge occurs, ventilate work area before resuming
service.

Additional health and safety information may be obtained from refrigerant and
lubricant manufacturers.

Special Considerations with R134a

R134a has been shown to be nonflammable at ambient temperature and
atmospheric pressure. However, tests under controlled conditions have indicated
that, at pressures above atmospheric and with air concentrations greater than 60%
by volume, R134a can form combustible mixtures.

While it is recognized that an ignition source is also required for combustion to
occur, the presence of combustible mixtures is a potentially dangerous situation
and should be avoided.

Under no circumstances should any equipment be pressure tested or leak tested
with Air/R134a mixtures. Do not use compressed air (shop air) for leak detection
in R134a systems.
