WARNINGS
ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THE UNIT. Before operating the unit, read and follow
the instructions and warnings in this manual. The operator must be familiar with air conditioning and refrigeration
systems, refrigerants, and the dangers of pressurized components. If the operator cannot read English, operating
instructions and safety precautions must be read and discussed in the operator’s native language.
VERIFY ALL SAFETY DEVICES ARE FUNCTIONING CORRECTLY BEFORE OPERATING THE UNIT.
PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. Do not overfill the internal storage vessel, because
overfilling may cause explosion and personal injury or death. Do not recover refrigerants into nonrefillable
containers; use service equipment certified to meet the requirements of SAE J2210 (R-134a recycling
equipment).
HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant may cause
personal injury. Wear protective equipment, including safety goggles. Disconnect hoses using extreme caution.
DO NOT BREATHE REFRIGERANT AND LUBRICANT VAPOR OR MIST. Exposure may cause personal
injury, especially to the eyes, nose, throat, and lungs. Use the unit in locations with mechanical ventilation that
provides at least four air changes per hour. If accidental system discharge occurs, ventilate the work area before
resuming service.
TO REDUCE THE RISK OF FIRE, avoid the use of an extension cord, which may overheat. However, if you
must use an extension cord, use a No. 14 AWG minimum, and keep it as short as possible. Do not use this
equipment in the vicinity of spilled or open containers of gasoline or other flammable substances.
R-134a SERVICE EQUIPMENT OR VEHICLE A/C SYSTEMS SHOULD NOT BE PRESSURE TESTED OR
LEAK TESTED WITH COMPRESSED AIR. Some mixtures of air/R-134a have been combustible at elevated
pressures. These mixtures are potentially dangerous and may result in fire or explosion causing personal injury
or property damage.
USE THE ACR2005 UNIT ONLY WITH R-134a REFRIGERANT. Cross contamination with other refrigerant
types will cause severe damage to the A/C system and to service tools and equipment. Do not mix refrigerant
types through a system or in the same container!
HIGH VOLTAGE ELECTRICITY INSIDE THE UNIT HAS A RISK OF ELECTRICAL SHOCK. Exposure may
cause personal injury. Disconnect the power before servicing the unit.
Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.

Introduction
This manual contains important safety procedures concerning the
operation, use, and maintenance of this product. Failure to follow the
instructions contained in this manual may result in serious injury. If you
are unable to understand any of the contents of this manual, please bring
it to the attention of your supervisor. Do not operate this equipment unless
you have read and understand the contents of this manual.
The ACR2005 is a complete air conditioning service center for R-134a. It recovers,
recycles, evacuates, and recharges refrigerant quickly, accurately, and
automatically, with little attention needed from the technician. A microprocessor
controls the unit’s functions, and prompts on the display lead you through the
operation. These prompts are written so they are easy to understand and follow.
The entire service procedure can be done with one hookup to the vehicle. A builtin refrigerant identifier checks for contaminated refrigerant before recovery.
Pressures are shown on the high- and low-side gauges, and other operating
information is shown on the display.
Refrigerant is recovered into and charged out of an internal storage vessel (ISV).
The ACR2005 unit automatically refills this vessel with refrigerant from an
external source tank as needed in order to maintain a constant 12–15 lbs. (5.44 –
6.80 kg) of refrigerant available to be charged. Quick connections are all that’s
needed to replace the source tank when it’s empty.
Other timesaving features include automatic air purge, single pass recycling, and
automatic oil drain. The unit also automatically clears refrigerant after every job. A
red light on the top of the unit flashes whenever a process is complete, or when the
unit needs attention from the user.
The ACR2005 is UL listed and meets SAE specifications for recycled refrigerant.

Introduction
GENERAL OPERATING GUIDELINES
1. The voltage at the unit must be ±10% of the unit’s rated voltage. Errors
will be displayed on the screen. Extension cords must be a minimum of 14
AWG and kept as short as possible. Common causes for electrical
problems include:
• Long extension cords
• Faulty, overloaded electrical circuits
• Drop lights
• Incorrect ground or incorrect polarity
NOTE
displays the following messages:
VOLTAGE LINE ERROR
CHECK POLARITY
VOLTAGE READOUT WILL BE DISABLED
: If your electrical circuits have reversed polarity, the screen

regulations.
with an option to continue.
If you choose the CONTINUE option, the over- and under-voltage
protection built into the circuit board will be disabled. The unit may not
operate correctly. To ensure correct operation, you must use a circuit with
the correct polarity.
2. The display shows options and gives instructions for most service
maintenance tasks. Read the display prompts and follow the directions
given there.
3. To interrupt any function, press the PAUSE key, then press the
CONTINUE key to restart the procedure.
4. The ACR2005 prompts you to check the system oil drain bottle (on the
back of the unit) for recovered oil. Any system oil that is lost is
automatically drained during recovery. You must measure and record the
lost amount so you know how much new oil to add during charging. Refer
to the A/C system manufacturer’s service manuals for oil specifications.
Discard the oil following current local, state, and federal statutes, cases,
laws, and regulations.
5. In general, it is best to leave the ACR2005 main power ON throughout the
workday. This allows plenty of time for the unit to purge air from the tank and
refill the internal storage vessel. Turn the unit OFF at the end of the day.

Introduction
ACR2005 OVERVIEW
1. POWER UP—When the power is turned ON, the unit performs self-
diagnostics. When tests are complete, the display shows SELECT
OPERATION. Use the function keys (F-1 to F-5) to select the desired
operating mode.
If the ACR2005 is turned off with refrigerant pressure in the hoses, the
unit will prompt you to clear the hoses on power up. Verify the service
couplers are disconnected from any A/C system being serviced. If a hose
clear is performed when connected to an A/C system, the system will be
recovered into the ACR2005 without being tested for contamination.
Introduction of contaminated refrigerant into the unit will require service
which is NOT COVERED under warranty.
2. MAIN MENU—Shows the amount of refrigerant available for charging,
the current temperature, humidity, date, time, inlet valve status, and
operational status. The information appears in the upper corners of the
display. Use the function keys (F-1 to F-5) to select the mode, or press
SCROLL MENU for more choices.
3. SNAPSHOT MODE—Displays operating data about the vehicle’s A/C
system, including refrigerant purity, system pressure, A/C outlet
temperature; also A/C outlet air velocity using optional anemometer
attachment.
4. RECOVER MODE—Removes refrigerant from the A/C system, and
filters it during recovery for reuse.
5. VACUUM MODE—Evacuates air from the A/C system.
6. CHARGE MODE—Recharges the A/C system; charge amount can be
entered in pounds and hundredths of a pound, pounds and ounces, or
kilograms.
7. HOSE RECOVER MODE—Removes all excess refrigerant from the
hoses.
8. FLUSH MODE—Clears oil from the A/C system by reversing the flow
of refrigerant; then filters out the contaminants.
9. SETUP MODE—Allows you to configure the ACR2005 and run
internal diagnostics.
Before you begin any procedure, familiarize yourself with the components of
the unit (see diagrams in this section) and the operation.
