Question about Heating & Cooling
Although it is very dangerous to do this. I will tell you how to go about it.
You should have a set of gauges, called a manifold, there should be a red one and a blue gauge..
The red one is for the high side, the smallest of the freon lines and the blue one is for the low side, the larger of the tow lines going into your unit.
It is possible to connect the freon lines while the unit is running. Connect the red hose to the small freon line and if the ac is running this line should be hot or warm. Then connect the blue hose to the large freon line and it should have some sort of insulation on it and if you feel it, it will be cool if you have enough freon in the unit.
You read the gauges like this. With the ac unit running first look the high side(red gauge and hose) you should have a thermometer set where the outside air is being pulled through the unit by the condenser fan, the fan on top or somewhere in the unit that blows air across the coil. (radiator looking thing)
If the ouside air temperature is 100 degrees you add 32 to that which gives you 132. On the red gauge you will see small numbers below the outer numbers and these numbers are green for freon 22 and other colors for other freons and assuming that you have freon 22 in your ac unit these are the numbers you have to look at.
The outer gauge at an outdoor temp of 100 degrees should read around 296 0r 298 psig (pounds peer square inch)
The low side, the blue gauge, depending on the inside temp of your house should be around 60-65 psig if inside of the house isn't too much over 80 degrees. Any higher temp inside your house it will be higher than the 60-65 degrees.
If the readings don't match and you feel it needs freon NEVER charge the system through the high side (small tube) use the low side and don't turn the freon gas can upside down because you will be sending liquid freon into the compressor and that is called "Slugging" it. A no-no.
The blue gauge will also give you some information. Look at the outer gauge and if its near 65 degrees in your house, look at the smalll green numbers and you will see that the coil temperature is.
Hope this works for you. It is a very involved thing and you really should have an someone with some ac experience near by.

The slide system usually uses inline circuit breakers to control the power for the slide. Some are automatic reset and others have a small black button on the side that must be reset. On a motor coach you will find these in a storage compartment and they probably will not be labeled.
