Warnings and Cautions
WARNING
R410-A Refrigerant under Higher Pressure than R-22!
The units described in this manual use R410-A refrigerant which operates at 50 to 70% higher
pressures than R-22. Use only R-410A approved service equipment. Refrigerant cylinders are
painted with "pink" color to indicate the type of refrigerant and may contain a "dip" tube to allow
for charging of liquid refrigerant into the system. For specic handling concerns with R-410A,
please contact your local sales ofce.
Failure to use R-410A approved service equipment could result in standard equipment exploding
under R-410A higher pressure which could result in death or serious injury.
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.
USE ONLY THE FACTORY RECOMMENDED OIL TYPE!
Important!
Environmental Concerns
Scientic research has shown that certain man-made chemicals can a󰀨ect the earth's naturally occurring stratospheric ozone layer
when released to the atmosphere. In particular, several of the identied chemicals that may a󰀨ect the ozone layer are refrigerants
that contain chlorouorocarbons (CFC's) and those containing hydro-chlorouorocarbons (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 certied. 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.
