This article provides help in decoding air conditioner, boiler, furnace, heat pump, water heater data tags and determining the age, model, or specifications of that equipment. Green links show where you are. A few years ago my family spent 3 days waiting for a new thermal coupler and switch to be sent from Whirlpool and of course I had to pay for it out of.

Here we explain the meaning of each of the data names and contents of typical air conditioner system data tags. Mounting A 14wide threaded socket or adapter for attaching binoculars, small telescopes, and cameras to the pan head of a standard photo tripod. If your Maytag or Whirlpool bottom mount fridge is leaking water, it might have a blocked drain in the freezer section. The symptoms typically are periodic. WHIRLPOOL water heater This page was last updated 28 June 2012 The date of productionmanufacture or age of a WHIRLPOOL water heater can be determined. We include examples of how to make use of the data to estimate equipment age, capacity, and even its condition. Not all of the terms we define below will appear on all equipment or motor tags. The photo at page top shows the main data sticker from a 1. Click to enlarge any imageThis model, made. Sanyo, Inc., provides easy to read basic data about the system including its year of manufacture, refrigerant, electrical requirements. Article Contents. The photo shown here is for a conventional non split residential air conditioning compressor unit. Unless it has been painted over or lost, on most air conditioners and heat pumps, a metal, foil, or plastic tag or data sticker is usually affixed to the outdoor air conditioner or heat pump compressorcondenser housing. Depending on the age and equipment manufacturer. Manufacturer The air conditioning equipment manufacturer. Sketch at left on guessing the size of an air conditioner system is compliments of Carson Dunlop Associates. As we cite at REFERENCES, Carson Dunlop also provide a Technical Reference Guide with extensive details that aid in decoding HVAC equipment serial numbers and data tags. Model Number, Serial Number, and Cooling Capacity sometimes cooling capacity is coded into the model number but on. Sanyo compressor shown here, cooling capacity is stated explicitly. On older equipment the BTUH cooling capacity may be encoded in the model numbers. RATED COOLING CAPACITY discusses how to read the cooling capacity in BTUH or tons. The serial number of modern HVAC equipment encodes the year and month of manufacture thus the age of the equipment is shown. For equipment where the month and year of manufacture is not stated in plain English, Carson Dunlop provides a Technical Reference Guide manual that decodes that data. Voltage or VAC for the compressor and separately for the blower fan. In addition to specifying voltage, the cycles 5. HZ or 6. 0HZ. and current phases typically one phase for residential equipment may be specified. Branch Circuit Selection Current BCSC recommended for determining the required size of the branch circuit conductors wiring. Locked Rotor Amperage LRA specifies the maximum current that the. NEC Table 4. 30 1. A. LRA on an air conditioning compressor describes the amperage drawn by the motor briefly during motor startup. Locked rotor amperage is also called inrush current. Because it takes a lot of energy torque to get the still parts of an electric motor turning, LRA will always be higher than the current used to keep the motor turning once it has started FLA or RLA. Mission Game here. This is particularly true if the motor has an additional load resistance to turning at startup, such as trying to start an air conditioning compressor against refrigerant head pressure inside the compressor unit. The LRA of electric motors is 7. RLA or FLA a lot. The motors circuit breaker, especially on an air conditioning system which can draw high initial amps LRA will be sized to protect the electrical wiring of the motor circuit, but the breaker also will be chosen to tolerate a brief, high initial current draw to avoid nuisance tripping. In other words, the inrush current, because it is brief, does not need to figure in the selection of the wire sizing when wiring or fusing the motor, except to avoid nuisance tripping. Manual De Taller De Renault Sandero Rs'>Manual De Taller De Renault Sandero Rs. The relationship between the LRA and full load amperage FLA varies depending on the design of the electric motor being rated. Motors built to NEMA standards are assigned codes A through H. Each letter can be translated into multiplier x FLA to give LRA. To assist in avoiding nuisance tripping during compressor startup when high current is drawn momentarily, AC compressor circuit breakers may be permitted to be one size larger than the circuit breaker required by the wire size itself. LRA also affects the choice of the electric motor starter. Finally, an air conditioner motor will also draw its LRA current if the motor is frozen or stuck or has bad bearings which we hope will quickly trip the circuit breaker or blow the circuit fuse. Thanks to Patrick Greaux for requesting clarification of LRA. Minimum Circuit Ampacity MCA MCA can be used to determine the required size of branch circuit conductors wiring and also control switches supplying. For example, using NEC Table 3. However some experts. BCSC. Using the minimum permitted sized wire rather than the optimum size to a compressor may save a few dollars. Maximum Fuse or HACR type Breaker specifies the maximum overcurrent protection or MOP to be used to protect. The permitted ampacity of the equipment electrical circuit protection fuse or circuit breaker amps. MOP or Maximum Overcurrent Protection. If MOP is specified, the breaker or fuse protecting the equipment should match this number. A hermetic compressor draws varying amounts of current as its internal. Current draw is higher when starting the motor, and highest if the motor. Because fusing an air conditioning. On some older equipment. MOP is not specified. Only in the case that MOP is not specified can the overcurrent protection required be. RLA OR BCSC whichever is greater x 1. RLA x 2. 25 might be used. The National Electrical Code NEC specifies the degree to which a breaker or fuse may exceed the RLA. Rated Load Amperage or Running Load Amperage RLA, also called Rated Load Current or RLC on some equipment. This is the manufacturers anticipated. RLA is usually similar to FLA in amount. Typically RLA is about about 6. See NEC section 4. We sometimes can guess the size tons of cooling capacity of an air conditioning compressor by dividing the RLA number by 6, 7, or 8. For example a compressor RLA of 2. For more accurate means of determining air conditioner cooling capacity by several means including decoding the data tag, see COOLING CAPACITY, RATED. In air conditioning systems, typically a motor provides about one horsepower HP per ton of cooling capacity. Full Load Amperage FLA full load motor current draw, level at which the motor can be operated without damage. FLA is similar to RLA in amount.
