PrefaceThis is the harmonized CSA Group and UL Standard for Household and similar electrical appliances - Safety - Part 2-89: Particular requirements for commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or motor-compressor. It is the second edition of CSA C22.2 No. 60335-2-89 and the second edition of UL 60335-2-89. This edition of CSA C22.2 No. 60335-2-89 supersedes the previous edition published in 2017 as CAN/CSA-C22.2 No. 60335-2-89 (adopted IEC 60335-2-89:2010+A1:2012). This harmonized standard is based on IEC Publication 60335-2-89: third edition Household and similar electrical appliances - Safety - Part 2-89: Particular requirements for commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or motor-compressor issued June 2019, as revised by corrigendum 1 issued September 2019. IEC 60335-2-89 is copyrighted by the IEC. This harmonized Standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee are gratefully acknowledged.This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This Standard was reviewed by the CSA Subcommittee on Household Appliances for Refrigeration, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This Standard was also reviewed and approved by ULs Standards Technical Panel for Commercial Refrigerators and Freezers, STP 60335-2-89. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This clause of Part 1 is replaced by the following. This part of IEC 60335 specifies safety requirements for electrically operated commercial refrigerating appliances and ICE-MAKERS that have an incorporated motor-compressor or that are supplied in two units for assembly as a single appliance in accordance with the instructions (split system).NOTE 101 Examples of appliances that are within the scope of this standard are - REFRIGERATED DISPLAY and STORAGE CABINETS; - refrigerated trolley cabinets; - service counters and self-service counters; - blast chillers and blast freezers; - COMMERCIAL ICE-MAKERS. As far as is practicable, this standard deals with the common hazards presented by these types of appliances including those that use FLAMMABLE REFRIGERANTS and appliances employing R-744 refrigerant. This International Standard is not applicable to appliances with a mass of FLAMMABLE REFRIGERANT exceeding the limits specified in 22.110 or to appliances with that use refrigerants with a toxicity classification of B according to ISO 817.It does not cover those features of construction and operation of refrigerating appliances that are dealt with in ISO standards. NOTE 102 Attention is drawn to the fact that - for appliances intended to be used in vehicles or aboard ships or aircraft, additional requirements can be necessary; - in many countries, additional requirements are specified by national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. NOTE 103 This standard does not apply to - appliances using FLAMMABLE REFRIGERANT in TRANSCRITICAL REFRIGERATION SYSTEMS; - domestic refrigerating appliances (IEC 60335-2-24); - split systems having a REFRIGERANT CHARGE of FLAMMABLE REFRIGERANT exceeding 150 g in any REFRIGERATING CIRCUIT; - industrial refrigerating systems; - motor-compressors (IEC 60335-2-34); - commercial dispensing appliances and vending machines (IEC 60335-2-75); - commercial ice-cream appliances; - cold temperature rooms; - multiple refrigerated chambers with a remote motor-compressor. 1DV.1 D2 Modification to replace the second paragraph in Clause 1 of the Part 2 with the following:This part of UL/CSA 60335 specifies safety requirements for electrically operated commercial refrigerating appliances that have an incorporated compressor, refrigerating appliances that are supplied in two or more units for assembly as a single appliance in accordance with the manufacturers instructions (split system), and partial units intended for installation in a field erected system in accordance with: - CSA C22.1, Canadian Electrical Code (CE Code) Part I, in Canada; - NFPA 70, National Electrical Code (NEC), in the United States. 1DV.2 D2 Modification to add the following after the second paragraph in Clause 1 of the Part 2: This standard also contains the requirements for: - commercial refrigerators and freezers for use in fuel dispensing facilities (Annex 101.DVD); - factory assembled walk in coolers/freezers (Annex 101.DVE); - refrigerating units (Annex 101.DVF); - PARTIAL UNITS (Annex 101.DVG); - dispensing units (Annex 101.DVH); - commercial refrigeration products with rated voltage up to 15 000V (Annex 101.DVR); - Stirling refrigeration systems; and - laboratory refrigerators and freezers (for US only). 1DV.3 D1 Modification of the sixth paragraph in Clause 1 of the Part 2 by replacing it with the following:This standard does not take into account refrigerants other than refrigerant safety groups as defined by ISO 817 or ANSI/ASHRAE 34 as follows: a) A1; b) B1 [for use in appliances installed in machinery rooms as defined in accordance with ANSI/ASHRAE 15 (USA) or CSA B52 (Canada), or outdoors only]; and c) A2L, A2, and A3, refrigerants. 1DV.4 DR Modification of Clause 1 of the Part 2 by adding the following paragraph: All references to ISO 817 in this Part 2 also apply to ANSI/ASHRAE 34. ANSI/ASHRAE 34 shall take precedence over ISO 817. 1DV.5 D2 Modification of Note 103 in Clause 1 of the Part 2 by replacing it with the following: NOTE 103 This standard does not apply to - appliances using flammable refrigerant in transcritical refrigeration systems; - domestic refrigerating appliances (IEC 60335-2-24); - motor-compressors (IEC 60335-2-34); - vending machines (IEC 60335-2-75); - professional ice-cream appliances (IEC 60335-2-118); - laboratory refrigerators and freezers (for Canada only. In Canada, the applicable standard for laboratory refrigerators and freezers is CSA C22.2 No. 61010-2-011.)
