|
(1) A book of instructions for use as a guide or reference. (2) Made, done, performed or operated by hand. |
| Manual brazing
|
|
Brazing done by someone with use of a torch or arc welder. |
| Manual d
|
|
Manual D is the ACCA method for designing duct systems. Contractors often find it a laborious process and most duct systems are just installed, not designed. The amount of time necessary to design a duct system is certainly warranted in tract construction where the design is used repeatedly and for custom homes where the total cost of the home warrants a proper design. In short, designing a duct system is essential for proper equipment performance and customer comfort. |
| Manual j
|
|
Manual J is a widely accepted method of calculating the sensible and latent cooling (and heating) loads under design conditions. It was jointly developed by the Air Conditioning Contractors of America (ACCA) and the Air-Conditioning and Refrigeration Institute (ARI). |
| Manual motor starter
|
|
On/off switch equipped with a heating element that cuts off power to the motor when the normal current is exceeded. When the heater element temperature increases, it trips the switch to an open position and cuts off power to the motor. These starters are normally used for large motors. |
| Manual s
|
|
Manual S is the ACCA method of selecting air conditioning equipment to meet the design loads. It ensures that both the sensible capacity and the latent capacity of the selected equipment will be adequate to meet the cooling load. |
| Manual scroll
|
|
Manual scroll is a feature on some sabre saws that allows a simple turn of the scroll knob to move the blade in the direction of the cut without having to turn the entire saw body. |
| Manual thermal overload switch
|
|
A manual thermal overload switch, also called a circuit breaker, automatically switches off current to the motor to prevent damage from overheating under heavy use. It must be manually reset by pushing a reset button. |
| Manual welding
|
|
Welding done by someone with use of a torch or arc welder. |
| Manufacture
|
|
To create something from raw materials. |
