Refrigerant Emission Control - Trane RTHC Installation Operation & Maintenance

REFRIGERANT EMISSION CONTROL

Evidence from environmental scientists indicates that
the ozone in our upper atmosphere is being reduced,
due to the release of CFC fully halogenated
compounds.
The Trane Company encourages every effort to
eliminate, if possible, or vigorously reduce the
emission of CFC, HCFC and HFC refrigerants into
the atmosphere that result from installation,
operation, routine maintenance, or major services on
this equipment. Always act in a responsible manner
to conserve refrigerants for continued use, even
when acceptable alternatives are available.
Conservation and emission reduction can be
accomplished by following recommended Trane
operation, maintenance and service procedures, with
specific attention to the following:
1 Refrigerant used in any type of air conditioning or
refrigerating equipment should be recovered for
reuse, recovered and/or recycled for reuse,
reprocessed (reclaimed), or properly destroyed,
whenever it is removed from equipment by an
EPA certified Type 11 or Universal Technician.
Never release refrigerant into the atmosphere.
2 Always determine possible recycle or reclaim
requirements of the recovered refrigerant before
beginning recovery by any method. Questions
about recovered refrigerants and acceptable
refrigerant quality standards are addressed in ARI
Standard 700.
3 Use approved containment vessels and safety
standards. Comply with all applicable
transportation standards when shipping
refrigerant containers.
4 To minimize emissions while recovering
refrigerant, use recycling equipment. Always use
methods which will pull the required vacuum while
recovering and condensing refrigerant into
containment.
5 When leak checking with a trace of refrigerant and
nitrogen, only use R-134a on R-134a units. Be
aware of any new leak test methods which
eliminate refrigerant as a trace gas, but consult
Trane Pueblo technical service before adding any
other substance besides R-134a to the system.
6 When cleaning system components or parts,
avoid using CFC-11 (R-11) or CFC-113 (R-113).
Refrigeration system cleanup methods which use
filters and dryers are preferred. Do not use
solvents which have ozone depletion factors.
Properly dispose of used materials.

7 Take extra care to properly maintain all service
equipment that directly supports refrigeration
service work, such as gauges, hoses, vacuum
pumps and recycling equipment.
8 Stay aware of unit enhancements, conversion
refrigerants, compatible parts and manufacturer's
recommendations which will reduce refrigerant
emissions and increase equipment operating
efficiencies. Follow manufacturer's specific
guidelines for conversion of existing systems.
9 In order to assist in reducing power generation
emissions, always attempt to improve equipment
performance with improved maintenance and
operations that will help conserve energy
resources.
