Propane is approved for use as a refrigerant in commercial, self-contained units in Canada 
and USA under limited use conditions. It can be used in new equipment only, retrofitting is 
not allowed, with a limited charge of up to 150 grams (5.3 oz) per refrigeration circuit. Even 
though this is a small amount, it still presents a fire/explosion hazard if it leaks out of refrig-
erant containing parts. When mixed with air, a flammable propane-air mixture can be created 
and easily ignited by sparks, open flames, or hot surfaces. This is particularly true in confined 
zones. Propane is heavier than air and tends to settle at lower points.  

 
To mitigate the risk, please follow the precautionary measures as follows: 

 
• Avoid unit installation in areas with open flames (kitchens, repair garages or the like), or 

in vicinity of open flames or high surface temperatures. 

• Avoid unit installation in confined spaces. Well ventilated areas are preferred. Keep clear 

all ventilation openings of obstructions. 

• Do not rely on smell to detect potential leaks of propane refrigerant. Propane refrigerant is 

a high purity propane gas and does not contain any stenching agent(s). Stenching agents 
are typically used in fuel-grade propane and natural gas to detect their presence in air by 
relying on smell. 

• All repairs must be performed in well ventilated areas. 
• To minimize the risk of possible ignition due to incorrect parts or improper service, compo-

nent parts shall be replaced with like components and servicing shall be done by service 
personnel authorized by Minus Forty Technologies Corp. 

• Do not attempt to modify the unit or remove any functional part(s) from the unit. 
• Handle the unit with care to avoid any damage. 
• When transporting the unit, all appropriate safety considerations must be considered. 

Check with local Department of Transportation for detailed requirements pertaining to 
transportation of flammable gasses.
