Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth's naturally
occurring stratospheric ozone layer when released to the atmosphere. In particular, several
of the identified chemicals that may affect the ozone layer are refrigerants that contain
chlorofluorocarbons (CFC's) and those containing hydro-chlorofluorocarbons (HCFC's).
Not all refrigerants containing these compounds have the same potential impact to the
environment. The Company advocates the responsible handling of all refrigerants, including
industry replacements for CFC's such as HCFC's and HFC's.
Responsible Refrigerant Practices
The manufacturer believes that responsible refrigerant practices are important to the
environment, our customers, and the air conditioning industry. All technicians who handle
refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements
for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment
that is used in these service procedures. In addition, some states or municipalities may
have additional requirements that must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
NOTICE
Use appropriate oil with R410A systems. Oil type is found at the bottom of Connection Pipe
Requirements table (included in the outdoor unit installation manual). R-410A systems utilize POE
(Polyolester) or PVE(Polyvinyl Ether) oil. Both oil types absorb moisture readily, yet, lubrication
properties vary. Do not leave the sealed system open to atmosphere except during service for a
short period of time. If the sealed system is left open longer than four hours, the compressor oil
must be changed. These systems utilize strainers placed before and after the expansion device in
the outdoor unit, if debris or moisture is suspected, these strainers must be changed. Do not break
a vacuum with air. Do not leak check the sealed system with compressed air. Unless instructed by
factory service representative, external refrigeration driers are prohibited.
