Appendix V to Subpart G of Part 82 - Substitutes Subject to Use Restrictions and Unacceptable Substitutes Listed in the December 1, 2016 Final Rule

Refrigerants - Acceptable Subject to Use Conditions

End-use Substitute Decision Use conditions Further information
Commercial ice machines (self-contained) (new only) Propane (R-290) Acceptable, subject to use conditions As of January 3, 2017:
This refrigerant may be used only in new equipment designed specifically and clearly identified for the refrigerant - i.e., this refrigerant may not be used as a conversion or “retrofit” refrigerant for existing equipment
Applicable OSHA requirements at 29 CFR part 1910 must be followed, including those at 29 CFR 1910.106 (flammable and combustible liquids), 1910.110 (storage and handling of liquefied petroleum gases), 1910.157 (portable fire extinguishers), and 1910.1000 (toxic and hazardous substances).

This refrigerant may be used only in self-contained commercial ice machines that meet all requirements listed in Supplement SA to UL 563.1 2 5 In cases where this rule includes requirements more stringent than those in UL 563, the equipment must meet the requirements of the final rule in place of the requirements in the UL Standard

The charge size must not exceed 150g (5.29 oz) in each refrigerant circuit of a commercial ice machine

Proper ventilation should be maintained at all times during

As provided in clauses SA6.1.1 and SA6.1.2 of UL 563, the following markings must be attached at the locations provided and must be permanent:

the manufacture and storage of equipment containing hydrocarbon refrigerants through

(a) “DANGER - Risk of Fire or Explosion. Flammable Refrigerant Used. Do Not Use Mechanical Devices To Defrost Refrigerator. Do Not Puncture Refrigerant Tubing.” This marking must be provided on or near any evaporators that can be contacted by the consumer

adherence to good manufacturing practices as per 29 CFR 1910.106. If refrigerant levels in the air surrounding the equipment rise above one-

(c) “CAUTION - Risk of Fire or Explosion. Flammable Refrigerant Used. Consult Repair Manual/Owner's Guide Before Attempting To Service This Product. All Safety Precautions Must be Followed.” This marking must be located near the machine compartment


Technicians and equipment manufacturers should wear appropriate personal protec- tive equipment, including

(d) “CAUTION - Risk of Fire or Explosion. Dispose of Properly In Accordance With Federal Or Local Regulations. Flammable Refrigerant Used.” This marking must be provided on the exterior of the refrigeration equipment

chemical goggles and protective gloves, when handling propane. Special care should be taken to avoid contact with

(e) “CAUTION - Risk of Fire or Explosion Due To Puncture Of Refrigerant Tubing; Follow Handling Instructions Carefully. Flammable Refrigerant Used.” This marking must be provided near all exposed refrigerant tubing

the skin since propane, like many refrigerants, can cause freeze burns on the skin.

All of these markings must be in letters no less than 6.4 mm ( 1/4 inch) high
The equipment must have red Pantone Matching System

A Class B dry powder type fire extinguisher should be kept nearby.

(PMS) #185 marked pipes, hoses, or other devices through which the refrigerant passes, to indicate the use of a flammable refrigerant. This color must be applied at all service ports and other parts of the system where service puncturing or other actions creating an opening from the refrigerant circuit to the atmosphere might be expected and must extend a minimum of one (1) inch in both directions from such locations

Technicians should only use spark-proof tools when working on equipment with propane.
Any recovery equipment used should be designed for flammable refrigerants.
Any refrigerant releases should be in a well-ventilated area, such as outside of a building.
Only technicians specifically trained in handling flammable refrigerants should service equipment containing propane. Technicians should gain an understanding of minimizing the risk of fire and the steps to use flammable refrigerants safely.
Room occupants should evacuate the space immediately following the accidental release of this refrigerant.
If a service port is added then, commercial ice machines or equipment using propane should have service aperture fittings that differ from fittings used in equipment or containers using non-flammable refrigerant. “Differ” means that either the diameter differs by at least 1/16 inch or the thread direction is reversed (i.e., right-handed vs. left-handed).
These different fittings should be permanently affixed to the unit at the point of service and maintained until the end-of-life of the unit, and should not be accessed with an adaptor.
Very low temperature refrigeration equipment (new only) Propane (R-290) Acceptable, subject to use conditions As of January 3, 2017:
This refrigerant may be used only in new equipment designed specifically and clearly identified for the refrigerant - i.e., this refrigerant may not be used as a conversion or “retrofit” refrigerant for existing equipment

The charge size for the equipment must not exceed 150 grams (5.29 ounces) in each refrigerant circuit of the very low temperature refrigeration equipment

Proper ventilation should be maintained at all times during the manufacture and storage
