How to Vacuum A/C Lines

When it comes time to wake up the lamps, or hit the windshield wipers on a ‘ Stingrays, does it seem like your Vette needs a strong coffee I. As many C3 owners can undoubtedly attest, slow headlamps are a problem that plagues many Sharks. It is a very common affliction, but that makes it no less frustrating. Sometimes, the simplest questions receive the most complicated answers. That is most certainly the case with the opening and closing of the headlamps on all ‘ Corvettes, and the windshield wiper door through These relatively minor functions are operated by one of the most complex, convoluted, and downright bewildering systems in the entire car. The headlamps and windshield wiper door are operated by an extremely intricate vacuum system which utilizes suction created in the intake manifold by the running of the engine. Through a series of vacuum reservoirs, actuators, controls, and many, many meters of hoses, we get the seemingly straightforward rotation of our headlights. In the early through model Sharks, this vacuum is also drawn upon to open and close the panel that hides the windshield wipers. Unfortunately, the fact that this vacuum system is so complex also means that there are a great number of things that can go wrong.

How do you hook up a vacuum pump?

In reality, once you get to 15 inches of vacuum, you are only half finished. Why a Vacuum Pump? Many manufacturers recommend evacuation to well below microns. Some even call for evacuation to microns. At 15 inches of vacuum, you could still have an incredible amount of water vapor in the system. When you have water vapor in your system, the risk of icing up capillary tubing and expansion valves becomes much higher.

Hook up the wet vacuum to where ever the drain line ends, and make sure the connection is tight so you get maximum suction. I would us a pvc coupling at the end of my hose so I could just hook it up .

Turn off the electricity to the circuit. Hold mounting bracket to the wall, level it, then mark the screw hole locations and where to bore a hole for the refrigeration lines, condensate discharge line and electrical cable. From inside, bore hole into the block wall with rotary hammer and 3-inch-diameter masonry coring bit. Once the bit’s pilot penetrates the wall, finish boring the hole from the outside. Screw the mounting bracket to the wall, making sure it’s level.

Install the air-conditioning unit to the wall-mounted bracket. Pass the refrigeration lines and condensate discharge line through the hole in the wall. Attach a vertical chase directly below the hole in the exterior wall; the chase will house the refrigeration lines, condensate discharge line and electrical cable. Extend the condensate discharge line down to within a few inches of the ground by attaching a length of PVC pipe.

It’s also the numbering on the socket, if you’re underneath the chassis soldering wires to the socket. Now note that if you look at and I. Many early IC’s were in a round can, even more similar to the tube layout. Everything else in a tube is just some metal with vaccuum between it and the other parts. The small voltages and currents of a ohmmeter won’t damage anything, not even close. The “12” in the part number indicates that the heater is intended to be powered from 12 V.

Aug 16,  · The vacuum hook up for the wipers is coming off the intake manifold now and I would guess that before it went to the fuel pump? I can not find any vacuum leaks so I do not believe the is an open port anyplace that needs a cap.

Vacuum pump oil makes a fine lubricant at these connections. Layout 1 Created Date: Connect the vacuum pump to the service ports of the liquid line and the vapor line service valves. If the vacuum pump lines do not contain shut-off valves, hook up the vacuum Be careful when picking up and moving the indoor and outdoor units.

Get a partner to help, A conventional vacuum pump can be used by installing a vacuum pump adapter. Connect the plug to the input jack and hook the latches to the holes on either side of the jack until the plug is secure.

You can use this article as a basis to replace yours, just keep in mind it will be slightly different. The EEC Electronic Engine Control or computer uses electronic solenoids to send vacuum to valves in this case, three valves: The EEC sends a signal to the solenoid and it “opens” the valve to allow the engine vacuum through. The easiest way to understand this is with the EGR.

The TAB valve works the same way, it either directs the air pumped from the smog pump onward to the TAD valve we’ll get there or out to nowhere not used. When the TAB valve directs the air onto the TAD valve, the TAD valve either directs the air from the smog pump down into the catalytic converter, or into the back of the engine.

Max Advance Since the vacuum advance control unit is a part of the distributor, the number of degrees of vacuum advance is specified in DISTRIBUTOR degrees – NOT crankshaft degrees.

All values are at sea level. Venturi pumps are certainly popular with the do-it-yourself mechanic since cost is often times the biggest factor. I’ll give these pumps some credit since they can remove a substantial amount of air from the system if you have a decent compressor. Pulling a vacuum on the system is what’s most important in terms of end result to the DIY’er.

Regardless of sales literature, I believe you won’t be able to boil much water out of an automotive system with the vacuum level produced by a venturi pump. I was able to see that by using my micron gauge. We have several very useful items in the shop that derive their power from the guts of a venturi pump. It’s not uncommon to get ten or more years of service from a good electric pump. That may be a better option versus overworking your air compressor for an hour or more, just to get mediocre results.

Vacuuming your swimming pool is something that should be done on a weekly basis. Sometimes your swimming pool may not look dirty but there is actually lots of bacteria that you can not see growing on the walls and the floor of the swimming pool. The most important thing you have to remember when vacuuming any swimming pool is that have a good prime is the key to have great suction. Often many pool owners do not spend enough time properly priming the vacuum hose only to experience hours and hours of problems because they just can not get the debris off of the pool floor.

A portable air conditioner (PAC) is a self-contained portable system ideal for cooling single rooms. They typically sit on the floor and come with an installation kit for quick set up. Most models also have wheels so you can move them to different rooms, making them a nice alternative to window units.

A thorough evacuation is necessary after servicing or replacing system components or when converting to Freeze 12, R a, or any other refrigerant. It simply shows the steps required to draw a vacuum on the system to remove moisture and other contaminants and charge the system with oil and the refrigerant of your choice. The necessity of properly capturing any refrigerant already in the system must be noted. You really should do yourself, the rest of us, and the environment a favor and have that stuff removed and recycled by someone with a lot more experience and the proper equipment.

Only the connectors will be different. The processes described here involve toxic chemicals under high pressures. Please read the instructions that come with any equipment you purchase, rent, or borrow.

Vacuum Equipment and Process Tips

The above photo shows how the distributor vacuum hoses connect to the left carburetor but on some models, there is a vacuum advance cutoff that goes between the distributor advance and the carb so I’ve bypassed the cutoff for the sake of illustration. The cutoff is activated by a switch on the transmission. Bentley says it exists on all dual carb models except with manual transmission.

Two hoses connect to a temperature valve on the right air horn The red hose goes on the right nipple and goes to the control box on the air cleaner. The green hose goes to the rubber tee on the left carb for the brake booster line.

How to Vacuum an AC System by Ezmeralda Lee It is important to vacuum an air-conditioning system to remove any air or moisture that may damage the system in the long run. Moisture in the AC system is a serious problem, because moisture reduces the performance of the AC system and condensation of water can cause the AC system to freeze.

Condensed water particles corrode the AC system and cause long-term damage. Creating a vacuum deep enough to boil moisture away by using a vacuum pump on a regular basis is an effective, low-cost method of maintaining a healthy AC system. Pumps can be purchased or rented, if you don’t want to make a permanent investment.

The pump hose should be attached to the low-pressure port of the refrigerant gauge. The hose is attached, in simplified terms, to the port that is found in the middle of the gauges. This step is very important in vacuuming the AC system.
