CONVERTING A RECOVERY RECYLING MACHINE

detailguy on Sat September 11, 2004 11:44 PM User is offline

i have a snap on act3000 recovery machine that has only been used about 3 hours i would like to use it as a 134 a recovery only i would like to know what i have to do to convert it over

This is copied from the EPA web site. As of this date, as far as knonw, it is not a legal operation to convert this machine to use 134a. UL listings and approval from EPA are granted to mfg'ers.
Perhaps..someone else has more info.
Good luck

Converting CFC-12 Equipment for Use with HFC-134a
EPA regulations prohibit technicians from changing fittings on the same unit back and forth so that the unit is used for CFC-12 in the morning, HFC-134a in the afternoon, then back to CFC-12 again, etc.

EPA regulations specify that when equipment is converted for use with a new refrigerant, the converted unit must be able to meet the applicable equipment standard set forth in the regulations. CFC-12 equipment may be permanently converted for use with HFC-134a under certain conditions. EPA intends to issue regulations placing certain restrictions on these retrofits in the future. Those restrictions may require that the manufacturer's service representative rather than the automotive service technician perform the retrofit, that a unit may only be retrofitted if retrofit procedures have been certified by an independent testing laboratory such as Underwriters Laboratories, and that an appropriate label is affixed to the unit. In addition, the retrofitted unit must meet the technical specifications of SAE standard J2210 and must have the capacity to purify used refrigerant to SAE standard J2099 for safe and direct return to the air conditioner following repairs.

Currently, however, in the absence of any EPA regulations, a service facility may perform such a retrofit, or may have the equipment manufacturer's service representative perform the retrofit, as long as the fittings are changed in accordance with EPA's Significant New Alternative Policy (SNAP) program regulations. The Agency cautions technicians, however, that even though recovering a given refrigerant using permanently converted equipment is legal, it may not be technically desirable. The equipment is designed to be compatible with specific refrigerants, and incompatible materials may cause short circuits, damage to seals, and compressor failure. Technicians should check with the recovery equipment manufacturer for recommendations about the recovery of refrigerants other than the refrigerant the equipment was originally intended to recover. Conversion of recovery equipment for use with other refrigerants may also invalidate any warranties offered by the equipment manufacturer.

that is the reason that i ask i dont intend to day any more r12 work at all you can only buy r12 in a 30 pound can 50 miles from vincennes
i am not going to recyle any freon i only put virgin freon in to all jobs the unit has a hpco circuit that is in it we hook up can can tap on 134
recoverd it and the unit work great the local dealer has a kit the has to installed on the unit to make it 134 usable the hose end that connect on the unit have to be unsolder and 134 end have to reinstalled on it new hoses and filters and new tank and when i talked to him about it he said he would do the install and supply all of the matrial that nned to make it work for the smae price

Gee, you guys sure make things long winded.

1. Change the hoses to those compatible with R134a, and of course the R134a service connector
2. Remove the old inline filter and replace with one that is compatible with R134a
3. If it has an automatic air purge valve, then replace this for one for purging R134a
4. Obviously before you start do make sure that all R12 has been removed from the system

I recently bought an old but unused Robinair recovery/ recycling machine and adapted it to flush ac systems with R134a in a closed loop, by brazing in a tee from the liquid side of the recovery tank, through a valve and out to an adaptor to connect up to various components, the recovery tank is pressurised by the returning vapour through the compressor (the returning refrigerant is filtered through a locally bought filter and adaptor block)
