||A number of non-approved/alternate refrigerants have entered the marketplace and are being advertised as "drop-in replacements" for R-12 and R-134a. The use of non-approved refrigerants such as R-22, hydrocarbons, and other refrigerant blends could cause safety, durability, and performance concerns if they are installed in Ford A/C systems. Identification of the type of refrigerant contained in vehicle A/C systems, before servicing, is necessary to prevent dealer service equipment and refrigerant supplies from being contaminated with non-approved refrigerants.
||Refrigerant identification must be performed prior to recovering the refrigerant into a recovery machine to prevent cross-contamination of the recovery machine and other A/C systems being serviced with that recovery machine. Refer to the following text.
Ford Motor Company
has approved the Rotunda Deluxe A/C Refrigerant Analyzer (198-00003) for use
on Ford and Lincoln-Mercury vehicles (Figure 1). The analyzer provides the technician
with a quick and easy way to identify the type and percentage of refrigerant
(R-134a, R-12, R-22, or flammable hydrocarbon). The analyzer can also provide
the percentage of air in the A/C system and automatically purge air from the
The A/C Refrigerant
Analyzer is designed to identify vapor gas samples taken directly from automotive
air conditioning systems or refrigerant storage cylinders. Refrigerant vapor
passes through the multiple sensor Non-Dispersive Infra-Red (NDIR) sensing unit.
The microprocessor calculates each refrigerant type and purity percentage which
is displayed on the analyzer's Liquid Crystal Display (LCD).
The analyzer identifies
the purity percentage of R-134a, R-12, R-22, hydrocarbon, and air in the sample.
If the purity percentage of the R-134a or R-12 is 98% or greater by weight,
a green "PASS" Light Emitting Diode (LED) will light. If refrigerants
R-134a or R-12 do not meet 98% purity levels, the red "FAIL" LED will
light. Levels of R-22 and flammable hydrocarbons above 2% will light the red
"FAIL" light. If a hydrocarbon is detected above 5%, both the "FAIL"
light and "HYDROCARBON" light will illuminate and a horn will sound
alerting the user of potential hazards.
The percent of air
contained in the sample will be displayed if the R-134a or R-12 content is 98%
or above. The analyzer eliminates the effect of air when determining the refrigerant
sample content because air is not considered a contaminant although air can
affect A/C system performance. Air will automatically be purged until a pure
refrigerant with a less than 2% by weight air measurement is reached.
Recovery Of Contaminated
If contaminated refrigerant
is detected, DO NOT recover the refrigerant into your R-134a or R-12
recovery/recycling equipment. Take the following actions:
- Repeat the test
to verify contaminated refrigerant is present.
- Advise the customer
of the contaminated A/C system and any additional cost to repair the system.
The customer may wish to return to the service facility which performed the
last A/C service.
- Recover the contaminated
refrigerant using suitable recovery-only equipment designed for capturing
and storing contaminated refrigerant. This equipment must only be used to
recover contaminated refrigerant to prevent the spread to other vehicles.
As an alternative, contact an A/C service facility in your area which has
the proper equipment for refrigerant recovery.
Repairing A Contaminated
Once the contaminated
refrigerant is removed from the system it will be necessary to repair the system.
Ford recommends that you do the following to be sure a quality repair is made:
- Determine the
cause of the failure.
- Determine which
parts will need to be replaced.
- Flush the heat
exchangers to remove any oil that may be degraded due to the contaminated
- Install a new
- Properly oil
match the system to verify that the correct amount of clean refrigerant oil
is present in the system.
- Evacuate the
system for 45 minutes.
- Recharge the
system, verify proper operation, and leak test.
Disposal Of Contaminated
Disposal of contaminated
refrigerant is a new process to the automotive industry. Listed below are companies
that will assist with disposal of contaminated refrigerant. Ford Motor Company
has not evaluated the processes of the listed refrigerant disposal companies
and is not endorsing or promoting their companies. Business transactions are
between the dealership and disposal companies. Disposal costs will vary between
$3.00 and $5.00 per pound, plus the cost of round trip cylinder shipping.
