STARTUP & SAFE OPERATION
9 Do not use a damaged unit. Check for shipping damage and place a claim with carrier if
damage is discovered.
9 The TC670RR should not be operated or serviced by any person who has not read all the
contents of this manual.
9 This manual describes normal operation and maintenance for the TC670RR. 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. The instructions should not be interpreted
to anticipate every possible contingency.
9 It is the responsibility of the owner/user to operate the TC670RRin accordance with all
laws and specifications which may apply.
9 Avoid breathing refrigerant or lubricant vapor. Exposure may irritate eyes, nose and
throat. Ventilate work area if accidental system discharge occurs.
9 Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and
can cause frostbite.
9 Follow the TC670RR operating procedures sequentially to avoid prematurely
disconnecting hoses or opening valves which may release refrigerant to the atmosphere.
9 Do not expose the TC670RR to moisture or operate in wet areas.
9 Use the TC670RR in locations with ventilation that provides at least four air changes per
hour.
9 Hoses must have shutoff devices within 12 inches of the connection point to the A/C to
minimize the introduction of air into the TC670RR and the release of refrigerant when
being disconnected.
9 Disconnect power before performing any maintenance or service on the TC670RR.
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 percent 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 and
R134a mixtures. Do not use compressed air for leak detection in R134a systems.
