29、hese requirements cover commercial lters for cooking oil rated 600 volts or less and intended for use in accordance with the National Electrical Code, NFPA 70. These requirements cover both portable lters and xed lters intended to be used with a specic fryer or fryers or with any fryer or fryers. 1.
30、2 These requirements cover oil lters used to lter cooking oil used in deep fat fryers usually found in commercial kitchens, restaurants, or other business establishments where food is dispensed. The lters consist of a pump motor to pump oil to and/or from a deep fat fryer and are capable of includin
31、g an integral oil heater. The requirements are also applicable to lters built into a fryer. 1.3 When a lter is provided as part of a larger appliance, these requirements cover the lter and related components. The other portions of the appliance are to be evaluated in accordance with the requirements
32、 that normally apply to that type of equipment. However, consideration shall be given to the interaction between the two portions of the appliance; for example, to the possibility that the entire appliance is capable of being exposed to hot cooking oil. 1.4 Deleted October 8, 2004 2 General 2.1 Comp
33、onents 2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components used in the products covered by this standard. 2.1.2 A component is not required to comply wi
34、th a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating established for the int
35、ended conditions of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic
36、 conditions. OCTOBER 8, 2004 COMMERCIAL FILTERS FOR COOKING OIL - UL 1889 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explan
37、atory or approximate information. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3 Glossary For the purpose of this standard the following deniti
38、ons apply. 3.1.1 ATTACHMENT PLUG A male contact device for the temporary connection of a exible cord or cable to a receptacle, cord connector, anged equipment power outlet, or other outlet device. 3.1.1 added June 16, 1998 3.1.2 CORD CONNECTOR A female contact device to be wired on a exible cord for
39、 use as an extension from an outlet to make a detachable electrical connection to an attachment plug or as an appliance coupler to an equipment inlet. 3.1.2 added June 16, 1998 3.1.3 FILTER, CENTRAL A unit that lters oil from one or more fryers (or other appliances) from a stationary position. Centr
40、al lters may derive their power from another appliance or directly from the building supply. These lters form an integral part of a larger appliance. 3.1.3 added June 16, 1998 3.1.4 FILTER, PORTABLE A unit that is intended to be moved from place to place for ltering oil from multiple fryers (or othe
41、r appliances), one at a time. These lters do not form part of and are not connected electrically, physically, or by permanent plumbing to any other appliance. 3.1.4 added June 16, 1998 3.1.5 FILTER, STATIONARY A unit that lters oil from one or more fryers (or other appliances) from a stationary posi
42、tion. These lters do not form part of and are not connected electrically or physically to any fryer or other appliance. However, they are not prohibited from being interconnected to another appliance or appliances by plumbing. 3.1.5 added June 16, 1998 3.1.6 FILTER, UNDER-FRYER A unit that is locate
43、d below the oil kettle of a fryer or bank of fryers (or other appliances), and is intended to lter cooking oil used by that appliance. An under-fryer lter obtains electrical power from the appliance being serviced and forms an integral part of that appliance. However, a unit that is constructed to b
44、e removable from the appliance without the use of tools for the purposes of cleaning or servicing another appliance specically designed for use with that lter is considered to be an under-fryer lter. 3.1.6 added June 16, 1998 3.1.7 NOZZLE A device connected to the end of the oil hose for the purpose
45、 of removing and/or returning oil to the intended appliance (fryer). The nozzle is intended to be held by the operator during use. 3.1.7 added June 16, 1998 OCTOBER 8, 2004 COMMERCIAL FILTERS FOR COOKING OIL - UL 1889 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION W
46、ITHOUT PERMISSION FROM UL 3.2 SAFETY CIRCUIT A primary or secondary circuit that is relied upon to prevent a risk of re, electric shock, or injury to persons; for example, an interlock circuit. 3.3 USER SERVICING Any servicing that is capable of being performed by personnel other than those who are
47、trained to maintain the particular appliance. Some examples of user servicing are: a) Attaching an accessory by means of an attachment plug and receptacle or by means of other separable connectors. b) Resetting or replacing any protective device in an appliance, or its receptacle circuit, that are c
48、apable of being overloaded by the user. c) Resetting a circuit breaker or replacing a fuse. d) Making a routine operating adjustment required to adapt the appliance for a different intended function. e) Routine cleaning. CONSTRUCTION 4 Accessories 4.1 An appliance having provisions for the use of an
49、 electrical accessory intended to be attached in the eld shall comply with the requirements in this standard, with or without an accessory installed. 4.2 Electrical connection of an accessory by the user shall be by means of a receptacle and plug-in connector. See 14.2. 4.3 The installation of an accessory by service personnel shall be by means of receptacles, plug-in connectors, insulated wire connectors, or by connection to existing wiring terminals. Receptacles, when used, shall
