Introduction
Introduction
Important! These instructions are for qualified personnel, trained and
experienced in the handling of refrigerants. Federal and state laws
may require the licensing of refrigerant handling personnel. Failure to
follow proper operating procedures may cause personal injury and
equipment damage
The Bacharach Test System’s Mobile Air Conditioning MAC2000 is
the most advanced refrigerant management system on the market
today. It is a complete automotive A/C service tool that will identify,
recover, recycle, flush and troubleshoot automotive R-134a A/C
systems in a fully automatic manner.
A large liquid crystal diode (LCD) display screen prompts the
technician for input and displays system status. An internal 30 pound
recovery tank and electronic scale ensure convenient refrigerant
storage and accurate refrigerant management.
Upon power up, the unit performs a self-test and, if necessary, a selfevacuation routine. The technician may then select the specific
function required for the job. During operation, the MAC2000 checks
for error conditions and alerts the technician if any exist.
The entire service procedure can be done with one hook-up to the
vehicle. A built-in refrigerant identifier checks for contaminated
refrigerant prior to recovery. Pressures are shown on the high and low
side gauges, and other operating information is shown on the screen.
Refrigerant is recovered into and charged out of an internal storage
tank. The MAC2000 unit automatically refills this tank with
refrigerant from an external source tank as needed in order to
maintain a constant 12–15 lbs (5.45–6.82kg) of refrigerant available
for charging. One quick connection is all that’s needed to replace the
source tank when it is empty.
Other time saving features include automatic air purge, single pass
recycling, and automatic oil drain. The unit also automatically clears
refrigerant from its high- and low-side hoses after every job. A red
light on top of the unit flashes whenever a process is complete or when
the unit needs attention from the technician.
The MAC2000 is ETL listed to UL standards and meets SAE
specifications for recycled refrigerant.

General Operating Guidelines
• The MAC2000 monitors the AC line voltage and disables itself if
the voltage drops below 100 VAC or rises above 135 VAC. An error
message will be displayed on screen when the line voltage is out of
tolerance. The unit must be turned OFF and then back ON to reset
the voltage monitoring circuitry. 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
- Improper ground or improper polarity
• The screen shows options and gives instructions for most service
and maintenance tasks. Read the on-screen prompts and follow
their instructions.
• The MAC2000 prompts a technician to check the system oil drain
bottle on the side of the unit for recovered oil. Any system oil that is
lost is automatically drained during recovery. A technician must
measure and record the lost amount of oil in order to know how
much new oil to add during charging. Refer to the A/C system
manufacturer’s service manuals for oil specifications. Dispose of
used oil properly.
• In general, it is best to leave the MAC2000 turned ON throughout
the workday. This allows the unit time to purge itself of air and
refill the internal storage tank. Turn the unit OFF at the end of the
day.

Initial Set-Up
Checking Vehicles for Possible
Contaminated Systems
Before every recovery, the MAC2000 automatically samples the
refrigerant in the vehicle’s A/C system. If the system fails the purity
level required, the unit tests a second time. In the event the system
fails a second time, the unit prompts that the hoses be disconnected
from the vehicle. Follow the on-screen prompts in order to clean out
the MAC2000.
Note: The MAC2000 must be disconnected from the vehicle before
starting the cleaning process. It is illegal to knowingly vent or allow
refrigerant to vent to the atmosphere. This illegal venting will occur if
the unit is left attached to the vehicle.
Please refer to your shop’s policy for dealing with contaminated
refrigerant.
2.3
External Source Tank Testing
The MAC2000 features an exclusive source tank refrigerant
identification process that checks the source refrigerant before it is
added to the unit’s internal tank. This testing is automatic and does
not require any action by the technician. This feature prevents
contaminated refrigerant from entering the MAC2000, thus rendering
it inoperable.

Operation
Operation
MAC2000 Operational Overview
The MAC2000 is an EPA-approved, ETL-listed, single-pass recycling
system. During the recovery operation, refrigerant is removed from
the vehicle and passed through an oil separator and filter drier before
entering the storage tank.
The MAC2000’s refrigerant weighing system is extremely accurate. It
has sophisticated error correction capability that minimizes incorrect
readings caused by bumps or vibration. Even with this protection,
however, the MAC2000 should be placed on level ground and out of
the way of foot traffic. Do not touch or move the unit while it is
operating!
To ensure that the displayed reading of recovered refrigerant is
accurate, the unit will perform a low side clearing routine, if
necessary, when the power is turned on. If refrigerant is sensed in the
accumulator, the screen will display “Clearing System”. This
indicates refrigerant in the accumulator is being transferred to the
storage tank.
At any time during system operation, pressing the Weight Convert
key can change the weight units. The available units are pounds only,
pounds & ounces, or kilograms.
Power Up – When power is applied, the unit performs a selfdiagnostics. When these tests are complete, the display shows “Select
mode.”
Main Data Display – (See illustration of Main Data Display in
Section 1.5 on Page 7.) Shows the date, time, ambient temperature,
RH%, AC line voltage, low- and high-side pressures, and the amount
of refrigerant available for charging. Use the function keys (F1 – F5)

MAC2000
Recovery Mode
The recovery mode removes all refrigerant from the vehicle’s A/C
system and stores it in the unit’s internal storage tank. Before
recovery begins, however, there must be pressure in the hoses. This
prevents inadvertent recovery of air or other contaminants from a
leaking system. The MAC2000 will automatically sense the presence
of refrigerant and confirm that it is not contaminated before starting
the recovery process.
Begin the refrigerant recovery process as follows:
1. If not already done, plug the MAC2000 into a properly grounded
AC outlet; set the Power switch to ON; then wait until the unit
completes its self diagnostics. The screen will display “Select
mode” when ready.
2. Press the Recovery mode function key and observe the following
message: “Hook-up the service hoses to vehicle.”
3. At this time hook up the service hoses, open the A/C system’s
service-port valves, and then press the unit’s Start key. The
refrigerant identifier will warm up, zero itself, and then display
the message “Analyzing sample, please wait . . .”
If the refrigerant is contaminated (meaning that it has somehow
been mixed with some other kind of refrigerant), the results will be
displayed along with the word “contaminated.” Note that the
unit will not allow the recovery operation to proceed when
refrigerant is contaminated.
If the refrigerant is found to meet specifications, the unit will
automatically proceed to recover the refrigerant. During the
recovery operation, refrigerant is removed from both the high and
low side of the vehicle’s A/C system. The screen will display
“Recovering refrigerant” along with showing the amount of
refrigerant being recovered.
4. When the A/C system has been recovered to a minimum vacuum of
9 inHg, the recovery process automatically stops. The following
events then occur:
18
•
The unit’s red light flashes and the beeper sounds, signaling
the technician that recovery is complete.
•
The screen reads “Recovery complete” and shows the weight
of the recovered refrigerant.
•
System oil is automatically drained into the oil drain bottle (see
MAC2000 Left-Side View, Page 5).
Instruction 2072-0400
MAC2000
Operation
Note: The MAC2000 will automatically restart the recovery process
if the unit senses a rise in the A/C system’s pressure.
5. After recovering the refrigerant from the A/C system, close the
service-port valves, and then remove the hoses from the vehicle.
Observe that the service hoses should remain under vacuum. This
ensures that no contaminants are introduced into the A/C system
during a recharge process.
6. The technician can now begin repairs on the A/C system.
3.4
Vacuum Mode (Evacuation)
The Vacuum mode is used to remove residual air and moisture from
the vehicle’s A/C system by pulling the system into a deep vacuum.
This mode is most often used after completing a repair that required
opening the A/C system to the atmosphere. Moisture and/or air in an
A/C system can cause erratic operation and must be removed before
recharging the system with refrigerant.
Evacuate a vehicle’s A/C system as follows:
1. If not already done, plug the MAC2000 into a properly grounded
AC outlet; set the Power switch to ON; then wait until the unit
completes its self diagnostics. The screen will display “Select

2. Connect the high- and low-side service hoses to their respective
service ports on the vehicle’s A/C system; then open the A/C
system’s service-port valves.
3. Press the Vacuum mode function key and observe that the screen
reads “Set VACUUM TIME now.” The minimum evacuation time
is 3 minutes. To change this time, press and hold the Increase key
until the desired time is shown.
4. Press the Start key to begin the evacuation process.
Note: Before evacuation begins, the MAC2000 checks if pressure is
present in the vehicle. If pressure is sensed, the unit will display the
message: “Error: You have pressure in the hoses. You must
first recover this refrigerant before proceeding.” If this error
message appears, first abort the evacuation process by pressing the
Reset key, recover the system per Section 3.3, then restart the
evacuation process by pressing the Vacuum mode function key.
5. The evacuation process continues for the amount of time set in

achieved. When the A/C system reaches the proper vacuum, the
unit’s red light and beeper signal evacuation is complete, and the
screen reads “Vacuum complete.” If the proper vacuum is not
achieved after 7 minutes of evacuation, the process stops, and the
technician is prompted to check for a leak.
Note: Depending on the altitude, the A/C system may not be able to
achieve 27 inHg. It is important that the altitude setting in the SetUp menu is correct for your location. The MAC2000 uses this
information to calculate and provide an equivalent set point for
your altitude. (For instance, at 6000 feet the equivalent set point
for your altitude pulls to 22 inHg before completing evacuation).
6.
Press the Reset key to return to the Main menu.
7. The technician can now proceed to charge the system.
3.5
Charge Mode
The Charge mode is designed to add a precise amount of refrigerant to
the vehicle’s A/C system. This mode can be used to either “top off” a
system, or do a complete recharge after the system has been evacuated
or flushed. The unit has a built-in default charge amount of 2 pounds
(0.91 kg). Other charge amounts can be entered in increments of
either 0.06 pounds, 1 ounce, or 0.02 kg.
1. If not already done, plug the MAC2000 into a properly grounded
AC outlet; set the Power switch to ON; then wait until the unit
completes its self diagnostics. The screen will display “Select
mode” when ready.
2. Press the Charge mode function key and observe that the message
“Hook-up the service hoses to vehicle” should appear. If not
already done, connect the high- and low-side service hoses to their
respective service ports on the vehicle’s A/C system, and then open
the system’s service-port valves.
Note that at the start of this step, before the service hoses are
connected, the MAC2000 first checks if the service hoses are under
a vacuum. This prevents air and other contaminants from being
introduced into the A/C system. If the message “The vehicle is
not properly evacuated” appears, perform one of the following:
20
•
If the refrigerant in the A/C system has just been recovered,
evacuate both the system and the service hoses per Section 3.4.
•
If the A/C system needs to be “topped off,” first ensure that the
service hoses are disconnected from the vehicle; then either
recover the hoses per Section 3.3 if they contain refrigerant, or
evacuate the hoses per Section 3.4 if they contain air.
Instruction 2072-0400
MAC2000
Operation
3. After entering the Charge mode, the following options are
available:
•
Press the Enter key to accept the 2.00 pound Default.
•
Press the Weight Convert key to change the “Set charge
weight” units.
•
Use the Increase or Decrease keys to set the desired charge
amount. Select the next higher value if the exact charge
amount cannot be entered. Press Enter to accept the charge
amount shown on the screen.
Note: The MAC2000 charges in one-ounce increments, regardless of
which unit of measure is selected. This means that sometimes the
exact charge amount cannot be entered. For example, the A/C
system may require a 1.03 kg charge. The MAC2000 will only allow
a setting of 1.02 kg or 1.04 kg. In this instance, always select the
next higher value. This difference is only 0.3 of an ounce, which will
not affect the vehicle’s A/C performance.
4. By default the MAC2000 charges liquid refrigerant directly into
the high side of the A/C system. A technician, however, may choose
to charge into both the high and low side by pressing the Low side
ON-OFF function key. Pressing this key toggles the low-side option
on and off. Important! Charging liquid directly into the low side of
the compressor could slug the compressor and cause permanent
damage. Check with the compressor manufacture before proceeding.
5. The screen should now show the amount of refrigerant set for
charging. Press the Start key to begin the charging process.
During the charging process, liquid refrigerant is drawn from the
unit’s internal storage tank and charged through the high side
(and optionally the low side) of the vehicle’s A/C system. The
screen will show the progress of this charging process.
Important! Do not disturb or bump the MAC2000 during charging
as any jarring movement can affect the charge accuracy.
Note: If an insufficient pressure differential exists between the tank
and the system, charging suspends and the MCR2000 goes into a
power-charge mode to increase tank pressure to complete the
charge. This normally occurs only when the unit has been in a very
cold environment prior to use.
6. When charging is complete, the red light and beeper signal that
the process is complete. The MAC2000 automatically goes into the
Snap-Shot mode, thus allowing a technician to obtain an afterservice snap-shot of important operating parameters of the A/C
system. Refer to Section 3.2 for details.

function key. Otherwise, press the Done function key to exit the
Snap-Shot mode.
8. Close the service-port valves; remove the service hoses from the
vehicle; then press the Start key to recover the hoses.
Important! If the hoses are not removed from the vehicle before the
Start key is pressed, the refrigerant in the vehicle will be recovered!
9. If any oil was removed during the recovery or evacuation process,
make sure that the proper amount of oil is added back into the
vehicle’s A/C high side port in accordance with the vehicle
manufacturer’s recommendations. Add an amount of new oil equal
to the amount collected in the oil drain bottle (see MAC2000 LeftSide View, Page 5).
3.6
System Flush Mode (Oil Flush)
The System Flush mode is designed to be used on General Motors
vehicles using their Oil Flush Adapter and Filter accessory. This
accessory is attached inline with the vehicle’s compressor and is used
to flush the A/C system with refrigerant. In this mode, refrigerant is
circulated through both the A/C system and the MAC2000 where an
oil separator removes the oil and returns oil-free refrigerant back into
the A/C system for further flushing. At the end of the cycle, the
refrigerant is completely removed from the A/C system and stored in
the unit’s internal storage tank. The flushing process can take up to
30–45 minutes to complete. Because of the variety of A/C system
configurations currently in service, the flush may bypass certain
sections of the A/C system. To ensure the complete system is flushed,
the technician may need to pinch off certain hoses to force the
refrigerant flush throughout the system.
1. Before beginning the flushing process, recover all refrigerant from
the vehicle’s A/C system per Section 3.3 Recovery Mode.
2. From the Main menu, press the Next menu function key to display
Menu 2, and then press the System flush function key to select the
System Flush mode. The unit reminds the technician to “Please
empty the purge oil bottle prior to flushing.”
3. Press Start to continue. The unit now reminds the technician to
install the inline flushing adapter and remove the orifice tube or
TXV valve before continuing.
4. If not already done, connect the high- and low-side service hoses to
their respective service ports, and ensure that the service-port
valves are open.

Start to accept the flush time shown on the screen. A minimum
flush time of 30 minutes is recommended.
Important! There must be a minimum of 12 pounds of refrigerant in
the internal storage tank in order to complete the System Flush
process. A message will be displayed if additional refrigerant needs
to be added. Add additional refrigerant by following the procedure
described in Section 3.8 Internal Tank Manual Refill.
6. Press the Start key to begin flushing. The MAC2000 begins
flushing the A/C system in the following manner:
•
The A/C system is first completely filled with refrigerant,
during which time the screen shows “Flushing – Charging.”
•
The system is now flushed for the time duration set in Step 5,
during which time the screen shows “Flushing system.”
•
After the system is flushed, all refrigerant is automatically
recovered. The screen shows “Recovering refrigerant”
during this process.
•
The flush cycle completes by draining the oil that was removed
during the flushing process into the unit’s oil drain bottle (see
MAC2000 Left-Side View, Page 5). The screen shows
“Draining oil” during this process.
Important! All oil was removed from the A/C system during the
System Flush operation. Be sure that the proper amount of oil is
added back into the vehicle’s A/C high side port in accordance with
the vehicle manufacturer’s recommendations.
7. The unit beeps and its red light flashes to indicate that the
flushing cycle is complete. The screen now reminds the technician
to remove the inline flushing adapter, and to reinstall the orifice
tube or TXV valve.
8. Evacuate and then recharge the A/C system per Sections 3.4
and 3.5.

Maintenance
Field maintenance of the MAC2000 is limited to the following:
• Changing the filter drier
• Tracking of refrigerant using the unit’s Refrigerant Management
System
• Replacing the external refrigerant source tank
• Replacing the printer paper
• Replacing the refrigerant identifier filter
All other maintenance should be performed by an authorized
Bacharach Service Center (Section 5.2).
4.1
Changing the Filter Drier
The MAC2000 has a unique filtering system that ensures the
refrigerant transferred to the storage tank is clean and moisture-free.
The filter drier must be changed periodically to ensure that the
system will work properly.
The MAC2000 will automatically indicate when the filter needs to be
changed. If the “Change Filter” message appears when the Recovery
mode is selected, it is best to complete that job before changing the
filter drier. “Change Filter” will be displayed on the screen
whenever the recovery mode is selected until the filter has been
replaced.
All refrigerant must be evacuated from the old filter before it is
removed from the unit. Follow the filter change procedures carefully
to minimize refrigerant loss and ensure only clean, moisture-free
refrigerant is transferred into the storage tank.

Replacing the Refrigerant Identifier Filter
Caution: Visually inspect the Refrigerant Identifier Filter every day. If
it begins to turn red, replace it immediately! You risk damaging the
identifier sensor if the filter is not replaced.
The refrigerant identifier filter is located on the control panel, directly
under the Low Side pressure gauge. The filter’s function is to protect
the refrigerant identifier sensor from contaminates. When this filter
starts to develop red spots, replace the filter immediately!
1. Remove the filter from its holder; then remove the tubing from
each end.
2. Position the new filter so that its flow-arrow points in the same
direction as the flow-arrow on the control panel.
3. Attach the tubing to the new filter, and press the filter back into
its holder.
