1-44 HVAC System - Manual
Refrigerant Recovery and Recharging
Tools Required
• J 39500-8 A/C Refrigerant Recovery, Recycling
and Recharging (ACR4) System
• J 41810 PureGuard 2
• J-41810 - 100A Active Flow Control Valve
Caution: 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.
Caution: 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.
Notice: 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.

Notice: To avoid system damage use only R-134a
dedicated tools when servicing the A/C system.
Notice: 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 0-rings. If lubricants other
than those specified are used, compressor failure
and/or fitting seizure may result.
Notice: 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 39500-8 removes the Refrigerant-134a from the
vehicle's A/C system. The recovery procedure uses
one filtering cycle. The evacuation procedure uses an
automatic multiple pass filtering cycle. These
filtering cycles ensure a constant supply of clean, dry
refrigerant for A/C system charging.
The Initial Set-Up Instruction Manual, provided with
the J 39500-8, contains specific procedures for proper
recovery, evacuation and recharging.
