Do you have to suck a vacuum before inputing this dye into ac system?
1481080
no if you have a partial charge then the injector should assist in sucking the dye in, better injectors are available then of course you want sufficient refrigerent to run for awhile so you get a good read on leaks
1481081
No you don't. Just add the dye. You might have to had some freon to get some pressure in your system so the leak will happen.

No, but see about vaccuming out accumulated dust. That can perhaps be a problem.

It is pre-charged, but you still have to have an HVAC professional vacuum the line out and release the refrigerant per the instructions. Unfortunately, only professionals have access to the tools needed. We called around, and estimates were around $200 to compete this after having it already all wired up and ready to go.

Not an option. You just get steam (on/off), works great, especially when you remove the brush attachment.

No, the battery is sealed in the unit. Keep in mind that the battery run time is only when you are pressing the trigger, so a vacuum "session" seems to be a lot longer than just 20-25 minutes of the old way when the vacuum runs idle while you move about, pick up, rearrange furniture, etc. I don't find it an issue at all, though I do grab it more often because it's so handy and don't need marathon vacuum sessions any more.

No..you are laying down the cleaning solution and then just sucking it up. You may want to go back later anddo a complete rinse if you think it is necessary.

Yes and put a Vacuum on it.It's just air more or less to check for leaks.It will cause you problems if you leave it in thereit's not Freon.

The unit should be turned until it drips oil from the tip. It would be impossible to connect in such a way that "no" air gets in , but it will be negligible. One reader suggests the system be under vacuum. I disagree, as the moment of connection, you will "suck in" air whereas a pressurized system will attempt to "discharge" which should help keep the air entrapped to a negligible amount. Either way is likely ok, but less air is less air and less air is better

The tool is a vacuum pump, not an air compressor. You need AC gauge lines to use the pump correctly.

No if you are using the canned foam. I vacuum my rug before cleaning, then scrub in the foam as directed and let dry. After your rug is dry vacuum again and you're finished. I did find that the foam had a strong odor so you may wish to have good ventilation while using.

standard no, if you get the extra large ziplock storage bag and vacum the air out yes.

Hi Grammacat, We found no instruction regarding this. We use these in a home with central air conditioning running. But I would also advise that you clean out your AC & filter every summer before turning it on. If it is already in use, consider cleaning it, otherwise you could have all kids of spores, etc., blowing in via the unit.

The red "on" switch has to be held up the entire time the vacuum services are required. Once released, the vacuum does not continue functioning. I've checked the instruction pamphlet several times but am unable to find anything to the contrary.

Yes. The vacuum is created by using Ziploc's hand pump with a valve that's installed in the bag. But just like any Ziploc you reuse, it should be washed. And, if you're not using "Perfect Portion" bags in side the vacuum bag, make sure the valve is clean as well, especially of blood or "juice" from meats.

Yes. You first have to cut it the length you want it and seal the end. Then, when you vacuum it, it must be sealed.

If any kind of liquid gets sucked in, it will immediately end up inside the vacuum pump and piston by ruining it. I would not recommend it for vacuuming out 100% of the air out of bags with liquid substances. If you decide to do this anyway, you will have to leave some air in the bag so that the liquids do not get past the valve and into the machine.

No instructions come with the gauges, however the hoses are color coded. Red for high pressure, blue is low pressure and yellow is for attaching to the vacuum pump, or to the Freon supply. When you charge a system, open the blue valve to let Freon enter the system. The red valve must remain closed, to prevent high pressure from entering the yellow hose system.
