or HFC-134a, including a blend refrigerant.
[[Page 565]]
1. Scope
The purpose of this standard is to provide equipment specifications
for the recovery of any single, specific refrigerant other than CFC-12
or HFC-134a, including a blend refrigerant, which are either (1) to be
returned to a refrigerant reclamation facility that will process the
refrigerant to ARI Standard 700-93 or equivalent new product
specifications at a minimum, or (2) to be recycled in approved
refrigerant recycling equipment, or (3) to be destroyed. This standard
applies to equipment used to service automobiles, light trucks, and
other vehicles with similar air conditioning systems.

Underwriters Laboratories or an--equivalent certifying laboratory to
meet this standard.
3.5 Label Requirements--The equipment shall have a label ``Designed
Certified by (Company Name) to meet EPA requirements for use only with
(the applicable refrigerant). The refrigerant from this equipment must
be processed to ARI 700-93 specifications or equivalent new product
specifications before reuse in a mobile air-conditioning system.'' The
minimum letter size shall be bold type 3 mm in height.
4. Safety Requirements
4.1 The equipment must comply with applicable federal, state, and
local requirements on equipment related to the handling of the
applicable refrigerant material. Safety precautions or notices or labels
related to the safe operation of the equipment shall also be prominently
displayed on the equipment and should state ``CAUTION--SHOULD BE
OPERATED BY CERTIFIED PERSONNEL.'' The safety identification shall be
located on the front near the controls.
4.2 The equipment must comply with applicable safety standards for
electrical and mechanical requirements.
5. Operating Instructions
5.1 The equipment manufacturer must provide operating instructions
that include information equivalent to that required by SAE J1629,
necessary maintenance procedures, and source information for replacement
parts and repair.
5.1.1 The instruction manual shall include the following information
on the lubricant removed: Only new lubricant, as identified by the
system manufacturer, should be replaced in the air conditioning system.
Removed lubricant from the system and/or the equipment shall be disposed
on in accordance with the applicable federal, state, and local
procedures and regulations.
5.2 The equipment must prominently display the manufacturer's name,
address, the type of refrigerant it is designed to extract, a service
telephone number, and any items that require maintenance or replacement
that affect the proper operation of the equipment. Operation manuals
must cover information for complete maintenance of the equipment to
assure proper operation.
6.1 Functional Description
6.1 The equipment must be capable of ensuring removal of refrigerant
from the system being serviced by reducing the system pressure to a
minimum of 102 mm (4 in) of mercury below atmospheric pressure (i.e., to
a vacuum). To prevent system delayed outgassing, the unit must have a
device that assures that the refrigerant has been recovered from the
air-conditioning system.
[[Page 566]]
6.1.1 Testing laboratory certification of the equipment capability
is required which shall process contaminated refrigerant samples at
specific temperatures.
6.2 The equipment must be preconditioned by processing 13.6 kg (30
lb) of the standard contaminated refrigerant at an ambient of 21 [deg]C
(70 [deg]F) before starting the test cycle. Sample amounts are not to
exceed 1.13 kg (2.5 lb) with sample amounts to be processed at 5 min.
intervals. The test method fixture, depicted in Figure 1 to appendix A
of this subpart, shall be operated at 21 [deg]C (70 [deg]F).
Contaminated refrigerant samples shall be processed at ambient
temperatures of 10 and 49 [deg]C, without equipment shutting due to any
safety devices employed in this equipment.
6.2.1 Standard contaminated refrigerant, 13.6 kg (30 lb) sample
size, shall consist of liquid refrigerant with 1000 ppm (by weight)
moisture at 21 [deg]C and 45,000 ppm (by weight) of oil (total of one-
third mineral oil 525 suspension nominal, one-third PAG with 100 cSt
viscosity at 40 [deg]C or equivalent, and one-third POE with 68 cSt
viscosity at 40 [deg]C or equivalent) and 1000 ppm by weight of
noncondensable gases (air). Refrigerant shall be identified prior to the
recovery process to 2% of the original
manufacturer's formulation submitted to, and accepted by, EPA under its
Significant New Alternatives Policy program, with the exception that any
flammable components shall be identified to 1%.
6.3 Portable refillable containers used in conjunction with this
equipment must meet applicable DOT Standards.
6.3.1 The container color must be gray with a yellow top to identify
that it contains used refrigerant. It must be permanently marked on the
outside surface in black print at least 20 mm high ``DIRTY [NAME OF
REFRIGERANT]--DO NOT USE, MUST BE PROCESSED''.
6.3.2 The portable refillable container shall have a unique thread
connection for the specific refrigerant.
6.3.3 During operation, the equipment shall provide overfill
protection to assure that the storage container liquid fill does not
exceed 80% of the tank's rated volume at 21 [deg]C per DOT Standard, 49
CFR 173.304, and the American Society of Mechanical Engineers.
6.4 Additional Storage Tank Requirements
6.4.1 The cylinder valve shall comply with UL 1769.
6.4.2 The pressure relief device shall comply with CGA Pamphlet S-
1.1.
6.4.3 The container assembly shall be marked to indicate the first
retest date, which shall be 5 years after date of manufacture. The
marking shall indicate that retest must be performed every subsequent 5
years. The marking shall be in letters at least 6 mm high.
6.5 All flexible hoses must meet SAE J2196 for service hoses except
that fittings shall be unique to the applicable refrigerant.
6.6 Service hoses must have shutoff devices located within 30 cm of
the connection point to the system being serviced to minimize
introduction of noncondensable gases into the recovery equipment during
connection and the release of the refrigerant during disconnection.
6.7 The equipment must be able to separate the lubricant from the
recovered refrigerant and accurately indicate the amount removed from
the simulated automotive system during processing in 30 mL units.
6.7.1 The purpose of indicating the amount of lubricant is to ensure
that a proper amount of new lubricant is returned to the mobile air
conditioning system for compressor lubrication.
6.7.2 Refrigerant dissolved in this lubricant must be accounted for
to prevent system lubricant overcharge of the mobile air-conditioning
system.
6.8 The equipment must be capable of continuous operation in
temperatures of 10 to 49 [deg]C and must comply with 6.1 and 6.2.
7. For test validation, the equipment is to be operated according to
the manufacturer's instructions.
Application
The purpose of this standard is to provide equipment specifications
for the recovery of any refrigerant other than CFC-12 or HFC-134a for
return to a refrigerant reclamation facility that will process it to ARI
Standard 700-93 (or for recycling in other EPA approved recycling
equipment, in the event that EPA in the future designates a standard for
equipment capable of recycling refrigerants other than CFC-12 or HFC-
134a).
