What is objective of air handling unit?
An air handler, or air handling unit (often abbreviated to AHU), is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to duct work that distributes the conditioned air through the building, and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served, without ductwork.Small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; these simple terminal units are called blower coils or fan coil unit. A larger air handler that conditions 100% outside air, and no recirculated air, is known as a makeup air unit(MAU). An air handler designed for outdoor use, typically on roofs, is known as a packaged unit (PU) or rooftop unit (RTU)
What are the safety procedures when using mechanical equipment?
First of all, pay attention to what you are doing and what you are working with.Always wear safety glasses or goggles when working with dangerous chemicals.Know where the laboratory safety equipment is located.Tell the instructor of any accidents immediately.Keep food and drinks out of the laboratory work area.When dealing with chemicals, always read labels carefully to be absolutely certain that you have the right chemical.Sometimes you will be told to use a certain concentration of a solution. In those cases, be sure you check the label for concentration as well as the name of the chemical.Never mix chemicals that you haven't been told to mix without an "okay" from the instructor.If you spill a chemical, wipe it up immediately andadvise the instructor. Be sure to let the instructor know what you have spilled.If you get any chemical on you, rinse it off immediately with lots of water and let the instructor know what you spilled on your way to rinsing it off.
What are PG threads?
* World-wide most commonly used type thread * Characterized by its major diameter and its pitch * Designated by the letter M followed by the value of the nominal diameter and the pitch, both expressed in millimetres and separated by the multiplication sign '×' * NPT Thread = National Pipe Thread* Taper rate for all NPT threads is 1/16* The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to straight thread fittings* PG Thread = Panzer-Gewinde (also Panzer-Rohr-Gewinde) * German thread type * Depth of thread smaller than NPT or Metric, but larger flank angle Part Number Index sorted By Thread Types & Sizes: Metric Threads NPT Threads PG Threads ---- TORQUE RECOMMENDATIONS FOR STRAIN RELIEF FITTINGSTorque in inlb (Nm)METAL STRAIN RELIEF FITTINGS PLASTIC STRAIN RELIEF FITTINGS DOME NUTS THREAD AND LOCK NUTS DOME NUTS THREAD AND LOCK NUTS PG 7, M12x1.5 36.9 (4.17) 55.3 (6.25) 14.4 (1.62) 22.1 (2.50) PG 9, PG 11, M16, PG 13.5, 3/8" NPT, 1/2" NPT, M16x1.5, M20x1.5 36.9 (4.17) 55.3 (6.25) 22.1 (2.50) 33.2 (3.75) PG 16, 1/2"NPT-E 44.2 (5.00) 66.4 (7.50) 29.5 (3.33) 44.2 (5.00) PG 21, PG 29, PG 36, PG 42, PG 48, 3/4"NPT, 1"NPT, 1-1/4"NPT, 1-1/2"NPT, M25x1.5, M32x1.5, M40x1.5, M50x1.5, M63x1.5 59.0 (6.67) 88.5 (10.00) 44.2 (5.00) 66.4 (7.50)Note: Torque for dome nuts was determined using a metal rod. It may vary for cable, depending on the crush resistance of the cable. We recommend to determine the actual torque empirically, testing the actual cable used. The values shown above are for reference only. Note: Nylon strain relief fittings installed in a threaded connection and exposed to elevated temperature should be retained with a sealant such as Locktite® to avoid a loose connection when temperature fluctuates. ---- Nema RatingsIP Ratings ---- provides cable products at competitive prices with exemplary customer service.

How do you reset a goodman compressor?
Any compressor has an internal overload which may go off due to bad condenser fan motor, clogged condenser, restriction of air, the only way to test is to check the condinuity between terminal common start and run if common open shut off system and allow 24 hours to reset if it doesn't reset may need new compressor
What are the indications and causes of an overload generators?
The speed and terminal voltage drastically reduces
What are the three letters on a compressor terminal block?

Do you need two jumpers from your outdoor condensor compressor to the start capacitor if you only have one and does it need 220 or 120 if it is a 40mfd rated for 330v?
Do you have a dual capacitor that starts both the compressor and the fan motor? You need 230V to power the compressor. You should have one wire from the capacitor going from the start terminal on the compressor and one going from the common terminal to common on the capacitor.
