How To Use An A/C Manifold Gauge Set

Gauges are used to read the pressure of various liquids and gases in a cooling system, as well as vacuum pressure when you are pressure testing or charging the device. There are a number of different ports on the HVAC gauge set, also known as a manifold, and the main difference in the types of manifolds is the number of ports that you have available to attach accessories to, as well as the pressure that the gauge set can withstand, which is important when working with different refrigerants. Step 1 Connect the high pressure side of the cooling line to the red port on the gauge. The red port and red gauge are always the high pressure gauges. You will want to attach a code-approved red hose, which is made to withstand high pressure, using the flare fittings that are included with it, to the high pressure port on the cooling unit. The high pressure port is typically of a different size and thread pitch than the low pressure side in order to avoid the potential for accidental incorrect hookups. Step 2 Connect the low pressure side to the blue port on the gauge. The low pressure side will be connected with a blue low pressure hose to the blue pressure gauge and the low pressure side of the cooling unit. This will allow for the proper flow of vacuum pressure or a micron meter in order to determine the vacuum pressure in the system already. Step 3 Attach a waste hose or vent hose to the center of the manifold set up.

Crap somewhere else, we have heard your opinion. This thread is about what people have found to be true. If you think wire matters, but disagree with another poster’s preference or findings, politely say that your experience was different, and state what YOU found to be true. This thread has no right or wrong. That goes two ways. I’m gathering data on some upcoming modification projects, many of which involve upgrading the internal wire of some of my components and speakers.

What I am noticing is that there are a lot of very exotic offerings out there, but not very many reviews by users who have actually given these products a shot. In particular, I am interested in any feedback on what wire people have tried, and what their results were. There are lots of testimonies about Cardas and Vampire. That’s fine, and I’m sure it’s very good wire.

I would be comfortable using it, but before I made that choice, I would want some discussion about how these two brands compare to these offerings, in particular feel free to suggest others: But I can’t find good reviews or convincing commentary about them anywhere. That’s why I’m starting this thread.

Make use of the second factory battery tray and have the install look as factory as possible. These are special crimpers used for “open barrel” terminals. You can search for “delphi crimpers” and find them. The crimpers allow you to make this type of crimp, which is critical. If the crimp is not right, the terminals will not slide into the connector. Start by installing the battery isolator. GM calls this a “secondary auxiliary relay”.

It goes on the firewall, up and left from the brake booster. How you mount it is up to you. If your truck is like mine, then it doesn’t have the needed studs from the factory. Install the relay that controls the battery isolator. It is also placed on the firewall directly above the wire coming from the alternator. Install the fuse holder intended for dual battery use.

Testimonials I was surfing on the internet recently reading some of the forums on RV AC Electricity and was astounded by the confusion over AC electricity, particularly amp usage of AC electricity. This goes to show you how unless you’re working with it every day, we take electricity for granted. After all , if I’m not having any problems what need is there for me to understand it? By reading the forums the answer appears to be as soon as you purchase your first rv , start tripping a few breakers, and all of a sudden we’re wondering what in the world is going on.

With rv’s getting bigger, fancier, and adding all the comforts of home and more power requirements have naturally increased resulting in the mysterious world of 50 amp service. If you think I’m exagerating just read some of the forums.

For your electric fencing project, this is absolutely necessary. You just cannot have a good, working electric fence without it. I moved my fenced area for the pigs farther from the house, so needed to extend the wire another 50 feet.

This unique function is ideal for capturing switch activation forces, sharp breaks, and other short-duration applications. Configurable start and stop triggers are provided. The data acquisition rate is variable and can be slowed to also capture longer events, such as structure relaxation, material expansion, and others. Using a Series 7 gauge could replace cumbersome and expensive data acquisition hardware and software. Up to three steps may be programmed for a single footswitch activation.

I RV was kind enough to include one in the start-up kit they furnished. They cost a minimal amount, are a necessity and in our case was furnished by the dealer. Dog Bone Adapter lets you hook up to 15 amp outlets. Weatherproof jacket encloses 10 gauge, 3 wire cord for safe, free-flowing AC power. Molded plug and socket. Three insulated 6-gauge copper conductors and one insulated 8-gauge copper conductor are enclosed in a weatherproof outer jacket that resists oil, grease and ozone.

Won’t crack or become brittle and remains flexible below freezing temperatures. Jacket rated at V. Extra Heavy-duty 50 amp Power Cord If your going to run the full 50 AMP service and expect to be some distance from the source you’ll need this. Otherwise I would suggest that you not purchase one. If the service is that far away then you might want to repark your RV.

Permanent-magnet moving coil PMMC meter movements will not work correctly if directly connected to alternating current , because the direction of needle movement will change with each half-cycle of the AC. Figure below Permanent-magnet meter movements, like permanent-magnet motors, are devices whose motion depends on the polarity of the applied voltage or, you can think of it in terms of the direction of the current.

This is most easily accomplished through the use of devices called diodes.

Ice Is Building Up Moisture inside refrigerant lines can contaminate the lines, causing your air conditioning unit to become sluggish. Refrigerant already in the lines combines with the moisture that enters the lines. The two gold-colored valves are located on the refrigerant lines, where the lines enter the condensing unit. Thread each valve onto its respective hose by turning the valve in a clockwise motion, just as you would thread a watering hose onto an outside water spigot.

The left hose of the gauge attaches to the larger, low-pressure line’s service valve, while the right hose attaches to the smaller, high-pressure line’s service valve. The oil level should be at the fill line located on the sight glass; some pumps will have an “Oil Level” line. If it is not, add more oil. Thread it in a clockwise motion similar to Step 3. Switch the pump into the “On” position. Close each manifold valve and quickly shut off the vacuum pump. A reading other than 29 inHg, may mean a leak in the refrigerant system.

Things You Will Need Vacuum pump and vacuum pump oil Refrigerant manifold gauge Tips Replace the oil in your vacuum pump after each use. Vacuum pumps and refrigerant manifold gauges can be rented or purchased at your local home improvement, HVAC or automotive stores.

Understand the Laws Regarding Working on an Air Conditioner 1 Know what it is legal for an unlicensed homeowner to do to their own equipment. There is no national or federal law regulating what a private citizen can do with their own air conditioner. There are, however, laws requiring professional certification by the U.

Edit Article How to Charge a Home Air Conditioner. In this Article: Article Summary Understand the Laws Regarding Working on an Air Conditioner Check the System Determine What You Need Recharge Your AC Community Q&A One of the most expensive items on your electric utility bill in areas with hot summers is the cost of operating a central air conditioner.

Some corrective action steps can be taken by the do-it-yourselfer, though other corrections may require the services of a professional auto air conditioning specialist. The normal reading on both the high side and the low side should be 80 to PSI. If the PSI readings are lower than normal, hook up a can of refrigerant to the yellow hose and add enough refrigerant to the system to bring the PSI readings up to the normal ranges. Tip The low and high hoses have different size connectors.

The owner’s manual may have specific PSI ranges for your car’s make and model. Warning Do not add refrigerant to the system without first using the manifold gauges to check the refrigerant level. Do not overfill the system with refrigerant. Excess refrigerant must be removed by a professional and exhausted into a proper container.

Supplies Gather your supplies. For the sake of this build we are going to assume you have a 30 amp plug on your generator – like the one shown. If your have one different please adjust your supplies.

A power inverter uses direct current (DC) power to produce alternating current (AC) power, like in your home. In an RV, an inverter is connected to the battery and provides VAC for running appliances, like a coffee pot, microwave, or electronics like a TV, satellite receiver, computer, or cell phone charger.

Hi, I need to relocate the split air conditioner, but I don’t know the first step and next steps. Thank you, If you are not a service technician you probably won’t have the tools you will need to accomplish the move. Here is what it takes, step bye step. Pull the fuses or turn off the electrical breaker in the house. Hook up a gauge manifold to the Condensing unit ports for the liquid and suction lines.

Hook up a Refrigerant recovery machine to the manifold. Recover the refrigerant into recovery tanks down to a trace, no vacuum. Disconnect the electrical whip and control wiring from the condenser. Close off the service valves on the liquid and suction lines at the condenser. Slowly unscrew the copper line connections to the condensing unit to relieve any pressure that may exist from Refrigerant boiling out of the oil in the compressor and quickly cap them.

Move the unit to your new, firm and level location. Remove the old electrical disconnect and whip and move it to the condenser. Buy a new line set of the proper length or extend the old one with Refrigeration copper and couplings preserving the condenser couplings.
