Service Ports

[Circaflex]

edit due to nature of question asked

[killermiller]

If one were going to discharge some of the coolant, which service port is the one to be used? I see one on the compressor and one on a "fatter" tube?

One should not be discharging any coolent. It is illegal.

[yngndrw]

So how would one reduce the charge by a very small amount, for tuning ?

[killermiller]

Recover and recharge. There is the easy way and then the right way.

andrew: you just record the static, recover, and re-charge with slightely less static. This is how you take out refrigerant. NEVER VENT!

You need your epa 608 certification before you can do any of this however

And remember the static pressure will change slightly with ambient temperature changes.

i know i know, venting isnt good for the ozone. I know retuning would be best, but i dont have the money and i just want this SS to finally work correctly. It has major floodback and is irritating. Spending good money on a unit and not having it work correctly sucks. arg.

where in socal are you? what refrigerant are you using? im in claremont. Jinu is also in Socal. I would love to help you and i am sure jinu would also

Ah I see, long ago when I was first looking about Phase Change on here, it was taught by venting. :c

[Athanatos]

i was reading on some large scale sytems that there are pressure relief valve (for refrigerants) used, are they illegal?

No they are perfectly legal, and usually set to the maximum working pressure of the receiver. If the safeties malfunction or a valve is turned wrong and system pressure gets that high you will either have:
-A burst receiver, entire charge vented, collateral damages and injuries to people OR
-entire charge vented or partial charge vented

relief valves are

Im in Tustin/Irvine. Ive talked with Jinu, but i just cant afford a recharge. His price was on point, i just have other priorities to pay for. Charged with r507.

Send me a PM. Im pretty busy, and don't have a r507a recovery cylinder (only r402a for now) but if you want to recharge id just charge you a couple bucks for recovery unit oil

Would you rather a "high pressure", pressure vessel explode?

And some wonder why the laws are geting stricker to get rid of the DIYers

Stuff like this makes me shake my head.

Hey, we have to learn from somewhere. Teaching people is the way to go about things, not just making laws which exclude them hence making them operate illegally with no chance of (Legally) getting any advice.

The reason why I asked is because it contradicted what I had already been told. (A while ago from people on this forum, I might add.)

I'm in the UK and there's no cert. to learn from AFAIK.

[Xeon th MG Pony]

Yup there is now, New F gas law, I posted a nice big thread on it. They're making it even stricter too, the F gas is just the start of the wave.

City & Guilds, CORGI, Along with trade certs.

With all the info out on lagitamit sites with the facts there should be no question that venting is extremely illegal dam well near every where. and most certainly in the UK.

If any one sujests to another to vent a non HC gas I will be the first to vote for them to be banned !

CLEAN AIR ACT AND SUBSEQUENT AMENDMENTS
The 1990 Amendments to the Clean Air Act were signed by former President Bush on November 15, 1990. The amendments establish a National Recycling and Emissions Reduction Program to regulate the use and disposal of substances, including CFCs and HCFCs, which are harmful to humans and the environment. Title VI of this program is titled Stratospheric Ozone Protection; Section 608 of Title VI contains the National Recycling and Emission Reduction Program. Title VII is titled Provisions Relating to Enforcement. Final EPA regulations were published on May 14, 1993 and most recently revised with the EPA's March 12, 2004 rule change..
The objectives of this program are to reduce the use and emissions of abusive substances to the lowest achievable level and to maximize the recapture and recycling of such substances. In addition, the amendments establish new standards for safe disposal of these substances and new federally mandated certification procedures for those engaged in servicing refrigeration systems. The EPA regulations also require that new refrigeration and air conditioning appliances are equipped with a servicing aperture, or similar device, to facilitate recapture of refrigerants during service and repair.
The amendments also affect personnel repairing or servicing an appliance or industrial process refrigeration.
Under the statute, HVAC service personnel or any other individual may not "knowingly vent or otherwise knowingly release or dispose of any substance used as a refrigerant in such appliance in a manner which permits such substance to enter the environment." "De minimis" releases associated with good-faith attempts to recapture and recycle or safely dispose of any such substance shall not be subject to prohibition set forth in the preceding sentence. In other words, if you are attempting to minimize refrigerant losses, any minimal losses associated with recovery and recycling are allowed. This prohibition became effective July 1, 1992

- The EPA is authorized to obtain an injunction against the offending parties prohibiting them from discharging refrigerants into the air.

- The EPA may impose a $32,500-per-day penalty on the offender with the approval of the U.S. District Court. In addition, the EPA may seek to have criminal penalties and prison terms not exceeding five years assessed against any person who knowingly releases refrigerants into the atmosphere, and criminal fines and imprisonment may be assessed against any person who makes a false material statement or representation in any report, notice, or application required by the EPA.

- Criminal fines and penalties may also be assessed against any person who negligently or knowingly releases into the ambient air a hazardous air pollutant and who, as a result of the release, places another person in imminent danger of death or serious bodily injury. In the case of an intentional discharge, the prison term may be a maximum of 15 years.

- Finally, to encourage others to report violations of the act, the EPA is authorized to pay awards of up to $10,000 to any person who furnishes information that leads to a criminal conviction of another person for violation of the above prohibitions.

Since November 14, 1994, all HVAC service personnel must be fully trained in recommended service and repair procedures and techniques applicable to appliances containing refrigerants. In addition, since July 1, 1992 XE "July 1, 1992" , all individuals (service personnel, equipment owners, etc.) should be using their best efforts (good-faith procedures) to ensure that they do not permit inadvertent discharge of refrigerants into the atmosphere. A fine can be as much as $32,500 per day and per occurrence.

I was just re-reading the 608 Manual and this reminded me of this thread.
