The manufacturer urges that all 
HVAC servicers make every effort to 
eliminate, if possible, or vigorously 
reduce the emission of CFC, HCFC, 
and HFC refrigerants to the 
atmosphere. Always act in a 
responsible manner to conserve 
refrigerants for continued usage 
even when acceptable alternatives 
are available.

Never release refrigerant to the 
atmosphere! 

Always recover and/or recycle 
refrigerant for reuse, reprocessing 
(reclaimed), or properly dispose if 
removing from equipment.  

Always determine the recycle or 
reclaim requirements of the 
refrigerant before beginning the 
recovery procedure. 

Obtain a chemical analysis of the 
refrigerant if necessary. 

Questions about recovered 
refrigerant and acceptable refrigerant 
quality standards are addressed in 
ARI Standard 700.

Consult the manufacturer’s material 
safety data sheet (MSDS) for 
information on refrigerant handling 
to fully understand health, safety, 
storage, handling, and disposal 
requirements. 

Use only approved containment 
vessels and refer to appropriate 
safety standards. Comply with all 
applicable transportation standards 
when shipping refrigerant 
containers.

To minimize refrigerant emissions 
while recovering refrigerant, use the  
manufacturer’s recommended 
recycling equipment per the MSDS. 

Use equipment and methods which 
will pull the lowest possible system 
vacuum while recovering and 
condensing refrigerant. Equipment 
capable of pulling a vacuum of less 
than 1,000 microns (1.0 mm) of 
mercury is recommended. 

Do not open the unit to the 
atmosphere for service work until 
refrigerant is fully removed/
recovered. 

When leak-testing with trace 
refrigerant and nitrogen, use HCFC-
22 (R-22) rather than CFC-12 (R-12) or 
any other fully-halogenated 
refrigerant. 

Be aware of any new leak test 
methods which may eliminate 
refrigerants as a trace gas. 

Perform evacuation prior to charging 
with a vacuum pump capable of 
pulling a vacuum of 1,000 microns 
(1.0 mm) of mercury or less. Let the 
unit stand for 12 hours and with the 
vacuum not rising above 2,500 
microns (2.6 mm) of mercury. 

A rise above 2,500 microns (2.5 mm) 
of mercury indicates a leak test is 
required to locate and repair any 
leaks. A leak test is required on any 
repaired area. 

Charge refrigerant into the 
equipment only after equipment 
does not leak or contain moisture. 

Refer to proper refrigerant charge 
requirements in the maintenance 
section of this manual to ensure 
efficient machine operation. 

When charging is complete, purge or 
drain charging lines into an approved 
refrigerant container. 

Seal all used refrigerant containers 
with approved closure devices to 
prevent unused refrigerant from 
escaping to the atmosphere. 

Take extra care to properly maintain 
all service equipment directly 
supporting refrigerant service work 
such as gauges, hoses, vacuum 
pumps, and recycling equipment. 

When cleaning system components 
or parts, avoid using CFC-11 (R-11) or 
CFC-113 (R-113). Use only cleaning-
solvents that do not have ozone 
depletion factors. 

Properly dispose of used materials. 
Refrigeration system cleanup 
methods using filters and driers are 
preferred. 

Check for leaks when excessive 
purge operation is observed.

Keep abreast of unit enhancements, 
conversion refrigerants, compatible 
parts, and manufacturer’s 
recommendations that will reduce 
refrigerant emissions and increase 
equipment operating efficiencies.
