REFRIGERANT PURGING REQUIREMENTS
NOTE: Country and Local Codes for removal and processing
of this refrigerant must always take precedence over these
procedures.
• Minimum of 10 feet from building, verify wind
direction will not introduce refrigerant into building
• Verify refrigerant does not enter buildings through
intake air vents
• Although not required hydrocarbon refrigerants can be
recovered, instead of venting to the atmosphere.
• Purge system with dry nitrogen to displace any trapped
propane.
DANGER
Disconnect all electric power to the system. Shorting
electrical wires to refrigeration tubing may result in an
explosion.
