got a nice A/C machine off craigs. $100 and it is in real nice shape. Does anyone have manuals for this machine?

Also, It has 134 written on the recovery bottle. I assume it has 134 in it and has been used for 134. Iwould like to use it for R12. What should I do to clean it out to use it on R12? I would like to finally have AC in the coupe.

thanx

I have the manual for the 17700 don't know how much different these models are. Also I thought the 17xxx series were R12 and the 34xxxx series were R134.

The .PDF manual is to large to upload to this thread but I could send it to you.

The pressure characteristics between these two refrigerants are close enough that I have successfully converted an R12 recovery machine to R134a. I simply started with an empty tank. Changed the oil in the compressor, serviced the oil trap with a new dessicate bag and started using it for R134a. I can't imagine that you would run into any problems by converting a 134 machine to a 12 machine in the same way.

its definitely an r12 unit. I guess will just change the screw on filter and change the compressor oil. The tank has r134 in it, what do I need to do to get that emptied and cleaned out?

Don't you know anyone who needs their 134 a/c system charged. Charge a few systems out of it until it is almost empty and then use your imagination once there is only a small amount of refrigerant left.

Another idea would be to take the tank to someone with a frequently used 134 machine and let them recover what's in your tank into their system. Don't be surprised if they use a refrigerant identifier and a sealant detector on it first and refuse to take the free refrigerant.

I was thinking the r134 was not that expensive. would it be worth their while to take the r134 from an unknown source? I need to weigh the tank, maybe it is already pretty empty. what should i do to clean it out, ac flush swirl?

thanx[/QUOTe You can call Robinair and have them fax or email a manual.i have one i just got that im trying to convert to 134a.phone # 1800 822-5561 tell them what you got and they will send the manual.didnt charge for it either.

[QUOTE=keego140;2524831]
awesome thanx. i got lucky on this one. the guy I bought it from called and asked if I wanted the other cylinder for the machine, he found it hiding in the garage.. I went and got it, looks like it is half full of r12. so I am really stoked to get this cleaned out and charge my coupe. I will give Robinair a call and see if they will help me with the manual

thanx

Q: Did you get the Robinair 17400A converted successfully? Any "updates"?

(From my research/ and comparing the owner's manuals: The 17400A (r-12), and 34400 (R-134) are the SAME internally.- at least the major components. The only thing I see about converting a 17400A>34400 is any residual oil in the below components -Well that and legal issues..)




.

.
(Mods- I may create a separate thread on this issue, the below is some info I found regarding the parts differences of the 17400>17400A> 34400 that might be helpful to others searching for the same info so please don't delete. - there is very little info on the net on this subject.)



Q : Does anyone here have info /links about someone successfully converting a Robinair 17400, (originally R-12) to handle R-134?

I ask because I have a Robinair 17400, that I purchased several years ago and I'm now needing to convert it from R-12, to R-134.





From my research:

As sold:
Robinair
17400 =R-12 only
17400A=R-12 only
34400 = R134 only

17400A & 34400 are "sister" units. (Have same major internals)
RA17434=Compressor
RA18760=Accumulator Oil Separator
RA19067=Return Oil Separator


17400 has the SAME major internals as the 17400A (R-12), and 34400(R-134)..., all except the RA19067=Return Oil Separator that is. The 17400 return oil separator part number is RA17422, listed as "Return Oil Separator Valve"?(lol), pg 7 owners manual, Pg8 lists it as "Compressor Oil Separator.

17400 =
RA17434=Compressor
RA18760=Accumulator Oil Separator
RA17422 Robinair Compressor Return Oil Separator

Description:
RA17422 Robinair Compressor Return Oil Separator
Compressor Return Oil Separator Traps the compressor oil and stores it in the separator until it is returned by the normally open solenoid mounted on the top of the separator.

I'm thinking the different part number (RA17422 vs RA19067) is due to piping differences, 17400 having manual Air purge, 17400A & 34400 being automated /electrically controlled.




I am wondering how much different the RA17422 is from the later R134 compatible RA19067 is. I plan on changing the filter to the 34430, as used on the 17400A/34400, changing the compressor oil, and maybe "flushing" the Oil separator, and RA18760=Accumulator Oil Separator.

I'm concerned about "flushing" the component parts- and concerned of course about the differences or the RA17422>RA19067. If I don't flush- the problem I see is the leftover R-12 mineral oil , mixing with the R-134 PAG oil.

******

Common parts: 17400 >17400A >34400

RA17434=Compressor
RA18760=Accumulator Oil Separator (AKA="Heat Exchanger Oil Separator" in 17400 owners manual-and/or Evaporator /Condensor)


Parts differences, Robinair 17400> (17400A & 34400)

RA19067=Return Oil Separator (17400A, and 34400)
RA17422 Robinair Compressor Return Oil Separator =(17400)
