NOTICE: 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 chlorine, fluorine and carbon (CFCs) and those containing
hydrogen, chlorine, fluorine and carbon (HCFCs). Not all refrigerants containing these compounds have the same
potential impact to the environment.
G&D advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs
and HFCs.
NOTICE: RESPONSIBLE REFRIGERANT PRACTICES!
G&D 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.
WARNING: REFRIGERANT WARNING INFORMATION!
G&D Large Capacity Chillers use R404A or R448A refrigerant.
Use only manifold gauge sets designed for use with R404A or R448A refrigerant. Use only refrigerant recovery units
and cylinders designed for use with R404A or R448A refrigerant and POE oil.
R404A / R448A must only be charged into the unit in a liquid state!
R404A and R448A refrigerant must be stored in a clean, dry area out of sunlight. Never heat or allow refrigerant
storage cylinder temperatures to reach 125°F or store the cylinders where temperatures will exceed 125°F. Keep
cylinder valves tightly closed and valve caps in place when refrigerant cylinders are not in use.
WARNING: PERSONAL PROTECTIVE EQUIPMENT (PPE) REQUIRED!
Always refer to appropriate MSDS and OSHA guidelines when handling refrigerants. Use proper breathing, eye and
body protection when handling refrigerants. Failure to follow proper handling guidelines could result in serious injury
or death.
WARNING: LIVE ELECTRICAL COMPONENTS!
During installation, testing, servicing and troubleshooting of this product it may be necessary to work with live
electrical components. Have a qualified, licensed electrician or other person who has been properly trained in
working with live electrical components perform these tasks. Failure to follow all electrical safety precautions when
exposed to live electrical components could result in serious injury or death.
