Refrigerant Recovery and Recharging
Special tool
J 43600 ACR 2000 Air Conditioning Service Center
J 45037 A/C Oil Injector
WARNING
!
Avoid breathing the A/C Refrigerant 134a (R-
134a) and the lubricant vapor or the mist.
Exposure may irritate the eyes, nose, and
throat. Work in a well ventilated area. In order
to remove R-134a from the A/C system, use
service equipment that is certified to meet
the requirements of SAE J 2210 (R-134a
recycling equipment). If an accidental system
discharge occurs, ventilate the work area
before continuing service. Additional health
and safety information may be obtained from
the refrigerant and lubricant manufacturers.
WARNING
!
For personal protection, goggles and gloves
should be worn and a clean cloth wrapped
around fittings, valves, and connections
when doing work that includes opening the
refrigerant system. If R-134a comes in
contact with any part of the body severe
frostbite and personal injury can result. The
exposed area should be flushed immediately
with cold water and prompt medical help
should be obtained.
CAUTION
!
R-134a is the only approved refrigerant for
use in this vehicle. The use of any other
refrigerant may result in poor system
performance or component failure.
CAUTION
!
To avoid system damage use only R-134a
dedicated tools when servicing the A/C
system.
Heating, Ventilation and Air Conditioning:
CAUTION
!
Use only Polyalkylene Glycol Synthetic
Refrigerant Oil (PAG) for internal circulation
through the R-134a A/C system and only 525
viscosity mineral oil on fitting threads and O-
rings. If lubricants other than those specified
are used, compressor failure and/or fitting
seizure may result.
CAUTION
!
R-12 refrigerant and R-134a refrigerant must
never be mixed, even in the smallest of
amounts, as they are incompatible with each
other. If the refrigerants are mixed,
compressor failure is likely to occur. Refer to
the manufacturer instructions included with
the service equipment before servicing.
The J 43600 is a complete air conditioning service
center for R-134a. The ACR 2000 recovers, recycles,
evacuates and recharges A/C refrigerant quickly,
accurately and automatically. The unit has a display
screen that contains the function controls and displays
prompts that will lead the technician through the recover,
recycle, evacuate and recharge operations. R-134a is
recovered into and charged out of an internal storage
vessel. The ACR 2000 automatically replenishes this
vessel from an external source tank in order to maintain
a constant 5.45-6.82 kg (12-15 lbs) of A/C refrigerant.
The ACR 2000 has a built in A/C refrigerant identifier
that will test for contamination, prior to recovery and will
notify the technician if there are foreign gases present in
the A/C system. If foreign gases are present, the ACR
2000 will not recover the refrigerant from the A/C
system.
The ACR 2000 also features automatic air purge, single
pass recycling and an automatic oil drain.
Refer to the J 43600 ACR 2000 manual for operation
and setup instruction. Always recharge the A/C System
with the proper amount of R-134a. Refer to "Refrigerant
System Capacities" for the correct amount.
A/C Refrigerant System Oil Charge
Replenishing
If oil was removed from the A/C system during the
recovery process or due to component replacement, the
oil must be replenished. Oil can be injected into a
charged A/C system using J 45037. For the proper
quantities of oil to add to the A/C refrigerant system,
refer to "Refrigerant System Capacities".
