Safety First!
For use only by qualified and certified technicians in the safe use,
handling, and transporting of refrigerants. Please refer to flammable
refrigerant safety guides, regional codes and legislation for more
information.
WARNINGS – failure to heed these hazards and actions
can result in serious injury or death
1. Always use a grounded outlet
2. Always wear Proper Protective Equipment (PPE), which includes
gloves and safety glasses
3. Know proper safety and handling requirements of the refrigerant
in the Safety Data Sheet (SDS)
4. Avoid breathing refrigerant and oil vapors
5. Handle hoses and equipment carefully as refrigerant is under
high pressure and can cause frost bite
6. Do not operate in or near explosive atmospheres
7. Perform leak detection in accordance with recommended
practice to verify working environment is free from leaking
refrigerant as it can be toxic and or flammable
8. Only work in well-ventilated areas (minimum of 4 air exchanges
per hour)
9. Ensure power and extension cords are in good working condition
to prevent shock and spark hazards
Additional safety instructions for recovering A2L
refrigerants (e.g. R-32, R-1234yf, R-1234ze):
1. Adhere to local occupational safety codes and possess detailed
knowledge and skills when handling mildly flammable
refrigerants
2. Have emergency, evacuation, and fire protection plans
3. Designate and monitor a Temporary Flammable Zone with a
3-meter perimeter
4. Identify and disable all possible ignition sources within this Zone
5. Monitor air with a flammable refrigerant leak detector within
this Zone
6. Use a ventilation fan to maintain 5 air exchanges per hour within
this Zone
7. Make power connection of the recovery machine and other
equipment outside of the Temporary Hazard Zone
8. Bond the recovery machine outlet port to the recovery tank’s
unpainted fitting with a grounding strap to dissipate static
electricity buildup during recovery process
9. Ensure area around machine is free of debris that could enter air
vents and fan and cause accidental sparking
10. Always remain in attendance and observant when the machine
is running
11. Do not mix flammable refrigerants with air
12. Use an evacuated DOT recovery tank
13. If system has a suspected leak, stop recovery at 0 psig/bar to
prevent air from entering the recovery tank
14. After recovery, purge system with 100% nitrogen before opening
system for repair
CAUTIONS – failure to heed these conditions can cause
equipment damage.
1. Ensure that recovery machine, hoses, tank and other equipment
are in good working condition
2. Avoid overfilling recovery tanks by following refrigerant
manufacturer’s filling instructions and using a weight scale
3. Avoid cross contamination by not mixing refrigerants
