Refrigerant Safety - LG AR-DR12-05A Installation And Operation Manual

WARNING
Installation, startup, and service must be performed by a qualified installer, service agency, or gas supplier.
Improper installation, adjustment, service, maintenance, or alteration can cause personal injury or loss of life.
Installation, startup, and service must be performed by a qualified installer, service agency, or gas supplier.
Improper installation, adjustment, service, maintenance, or alteration can cause property damage.
The customer must provide proper equipment and fully trained installers to follow local safety requirements when receiving, installing, or
servicing equipment. Consult all local building, electrical, occupational safety, and gas codes.
Lock out all power supplies before servicing the unit to prevent accidental startup. All fan blades should be secured to prevent wind rotation.
Remove any restrictive device before restoring power.
The Clean Air Act of 1990 bans the intentional venting of refrigerant (CFC and HCFC) as of July 1, 1992. Approved methods of recovery,
recycling, or reclaiming refrigerant must be followed. Fines and / or incarceration may be levied for non-compliance.
ASHRAE Standards 15-2101 and 34-2010 offer guidelines that address refrigerant safety and the maximum allowable concentration of
refrigerant in an occupied space. Refrigerant will dissipate into the atmosphere, but a certain volume of air is required for this to occur safely.
For R410A refrigerant, the maximum allowable concentration of refrigerant is twenty-six (26) lbs. per 1,000 cubic feet of an occupied space.
Institutional buildings allow half of that concentration.
ASHRAE Standards 15 and 34 assume that if a system develops a leak, its entire refrigerant charge will dump into the area where the leak
occurs. To meet ASHRAE Standards 15 and 34, calculate the refrigerant concentration that may occur in the smallest room volume on the
system, and compare the results to the maximum allowable concentration number. Also, consult state and local codes in regards to refriger-
ant safety.
WARNING
Verify the maximum refrigerant concentration level for spaces served by DOAS meets the concentration limit for the application.
