INTRODUCTION

This machine is ETL Laboratories approved, in compliance with SAE J2788. We are dedicated to solving the issues surrounding the safe
containment and proper management of refrigerants. Your new machine incorporates the latest technology and state of the art features to aid you in
servicing R134a air conditioning and refrigeration systems.

NOTICE:

The SAE J2788 standard has, by design made recycling machines more complex than previous models that some End Users might be familiar with.
Some noticeable changes that the End User should expect from ALL new recycling machines are the following.

1. RECOVERY TIME: The average recovery time is approximately 30 minutes. This time is necessary to meet the SAE J2788 standard which requires
that the machine recovers at least 95% of the AC system refrigerant and cleans the refrigerant to a minimum of 95% purity.

2. HOT WEATHER: As the ambient temperature approaches 100°F, some End Users have experienced an increase in recovery time. This is due
to the natural response of R134a when its temperature is elevated. R134a has difficulty transforming from a gas into a liquid state at elevated
temperatures. The transformation into liquid is necessary for the machine to complete the recovery process. The End User might notice the same
effect when performing a TANK CHARGING operation.

3. COLD WEATHER: As the ambient temperature approaches 50°F, some End Users have experienced an increase in recovery time. This is due
to the natural response of R134a when its temperature is lowered. R134a has difficulty transforming from a liquid into a vapor state at reduced
temperatures. The transformation into vapor is necessary for the machine to complete the distilling process. The End User might notice the same
effect when performing a TANK CHARGING operation.

SAFETY SUMMARY

The following safety information is provided as guidelines to help you operate your new system under the safest possible conditions. Any equipment
that uses chemicals can be potentially dangerous to use when safety or safe handling instructions are not known or not followed. The following
safety instructions are to provide the user with the information necessary for safe use and operation. Please read and retain these instructions for
the continued safe use of your service system.

SAFETY INFORMATION

Every craftsman respects the tools with which they work. They know that the tools represent years of constantly improved designs and
developments. The true craftsman also knows that tools are dangerous if misused or abused. To reduce risk of discomfort, illness, or even death,
read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this equipment understands and
follows these safety instructions as well.

READ ALL SAFETY INFORMATION CAREFULLY before attempting to install, operate, or service this equipment. Failure to comply with these
instructions could result in personal injury and/or property damage.

RETAIN THE FOLLOWING SAFETY INFORMATION FOR FUTURE REFERENCE.

Published standards on safety are available and are listed at the end of this section under ADDITIONAL SAFETY INFORMATION.

The National Electrical Code, Occupational Safety and Health Act regulations, local industrial codes and local inspection requirements also provide a
basis for equipment installation, use, and service.

The following safety alert symbols identify important safety messages in this manual.

When you see one of the symbols shown here, be alert to the possibility of personal injury and carefully read the message that follows.

Never fill the tank to more than 80% of maximum capacity as this will not leave an expansion chamber for absorbing any pressure increases.

ELECTRICAL SHOCK HAZARDS

• To reduce the risk of electric shock, unplug the power supply cord from the outlet before attempting any maintenance or cleaning. Turning off
controls will not reduce this risk.

• Do not operate the machine with a damaged cord or plug — replace the cord or plug immediately. To reduce the risk of damage to electric plug
and cord, disconnect the power cord by pulling on the plug rather than the cord.

An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire, electric shock
and component damage. If extension cord must be used, make sure:
a. That pins on plug of extension cord are the same number, size, and shape as those on plug on recycler.
b. That extension cord is properly wired and in good electrical condition; and
c. That the wire size is large enough for the length of cord as specified below:

Length of cord in feet: 25 50 100 150

AWG size of cord: 16 12 10 8

MOTION HAZARDS

• Engine parts that are in motion and unexpected movement of a vehicle can injure or kill. When working near moving engine parts, wear snug fit
clothing and keep hands and fingers away from moving parts. Keep hoses and tools clear of moving parts. Always stay clear of moving engine
parts. Hoses and tools can be thrown through the air if not kept clear of moving engine parts.

• The unexpected movement of a vehicle can injure or kill. When working on vehicles always set the parking brake or block the wheels.

FUME HAZARDS

• FUMES, GASES, AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS, AND DEATH! To reduce the risk of discomfort, illness, or death, read,
understand, and follow the following safety instructions. In addition, make certain that anyone that uses the equipment understands and follows
these safety instructions as well.

• Avoid breathing A/C refrigerant and lubricant vapor mist. Exposure may irritate eyes, nose, and throat. To remove R134a from the A/C system,
use service equipment certified to meet the requirements of SAE J2788--R134a recycling equipment. Additional health and safety information
may be obtained from refrigerant and lubricant manufacturers.

• Always perform vehicle service in a properly ventilated area. Never run an engine without proper ventilation for its exhaust.

• Stop the recycling process if you develop momentary eye, nose, or throat irritation as this indicates inadequate ventilation. Stop work and take
necessary steps to improve ventilation in the work area.

HEAT/FREEZING HAZARDS

• When under pressure, refrigerants become liquid. When accidentally released from the liquid state they evaporate and become gaseous. As they
evaporate, they can freeze tissue very rapidly. When these gases are breathed in, the lungs can be seriously damaged. If sufficient
quantities are taken into the lungs, death can result. If you believe you have exposed your lungs to released refrigerant, seek immediate medical
assistance.

• Refrigerants can cause frostbite and severe burns to exposed skin. Refrigerants are under pressure and can be forcibly sprayed in all directions if
carelessly handled. Avoid contact with refrigerants and always wear protective gloves and make certain other exposed skin is properly covered.

• Refrigerants can also severely injure or cause permanent blindness to unprotected eyes. Refrigerants are under pressure and can be forcibly
sprayed in all directions if carelessly handled. Avoid contact with refrigerants and always wear safety goggles.

EXPLOSION/FLAME HAZARDS

• Never recover anything other than the approved refrigerants as specified on the machine. Alternate refrigerants may contain flammables such as
butane or propane and can explode or cause a fire. Recovering alternate refrigerants will also void the warranty on your machine.

• For general safety reasons, at the end of the working day or in between services (when services do not immediately follow), see to it that all valves
on hoses and the machine are closed.

ADDITIONAL SAFETY INFORMATION

For additional information concerning safety, refer to the following standards.
ANSI Standard Z87.1 — SAFE PRACTICE FOR OCCUPATION AND EDUCATIONAL EYE AND FACE PROTECTION - obtainable from the American National
Standards Institute, 11 West 42nd St., New York, NY 10036, Telephone [phone], Fax [phone] - www.ansi.org

CAUTION: This equipment should be used in locations with mechanical ventilation that provides at least four air changes per hour or the
equipment should be located at least 18 inches (457 mm) above the floor, or the equivalent.

CAUTION: Do not pressure test or leak test R134a service equipment and/or vehicle air conditioning systems with compressed air. Some

5

mixtures of air and R134a have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional health and safety information may be obtained from refrigerant manufacturers.

ATTENTION: Technicians using this equipment must be certified under EPA Section 609 (Environmental Protection Agency).

WARNING: There is the possibility of refrigerant contamination in the refrigerant container or the mobile A/C system being serviced or
refrigerant container. Before recycling use proper equipment such as a refrigerant identifier, if necessary.

NOTE: Use only new refrigerant oil to replace the amount removed during the recycling process. Used oil should be discarded per
applicable federal, state, and local requirements.

The manufacturer shall not be responsible for any additional costs associated with a product failure including, but not limited to, loss of
work time, loss of refrigerant, cross contamination of refrigerant, and unauthorized shipping and/or labor charges.

IMPORTANT: R134a systems have special fittings (per SAE specifications) to avoid cross-contamination with R12 systems. DO NOT adapt
your unit for a different refrigerant — system failure will result.

PERIODICALLY INSPECT AND MAINTAIN REFRIGERANT HOSES AND SEALS TO ENSURE THAT HOSES AND SEALS PREVENT THE ADDITION OF
EXCESS AIR, DUE TO LEAKS, DURING THE RECOVERY PROCESS, WHICH WOULD INCREASE THE NCG LEVEL IN THE RECOVERED REFRIGERANT.

CERTIFICATION

All technicians opening the refrigeration circuit in automotive air conditioning systems must now be certified in refrigerant recovery and recycling
procedures to be in compliance with Section 609 of the Clean Air Act Amendments of 1990. For information on certification call MACS Worldwide at
[phone].

PRINCIPLES OF OPERATION

In a single series of operations, the machine permits recovering and recycling refrigerant with no risk of release into the environment, and also
permits purging the A/C system of humidity and deposits contained in the oil. The machine is equipped with a built-in evaporator/separator that
removes oil and other impurities from the refrigerant recovered from the A/C system and collects them in a container for that purpose. The fluid is
then filtered, recycled and returned to the tank installed in the machine. The machine also permits running certain operational and leak tests on the
A/C system.

SETUP

The machine is supplied fully assembled and tested. Referring to Figure 3, mount the
hose with the BLUE quick-connect coupling on the male threaded connector indicated by
the BLUE LOW PRESSURE symbol and the hose with the RED quick-connect coupling on
the male threaded connector indicated by the RED HIGH PRESSURE symbol.

ALARMS

HIGH PRESSURE ALARM: Beeper and LCD advise when the pressure of the fluid in the circuit reaches 290 psi (20 bar). The recovery
operation is automatically interrupted. See page 24, Purging Non-Condensable Gases.

FULL TANK ALARM: Beeper and LCD advises when the tank is filled to more than 80% of maximum capacity; that is,
24 lbs (10.8 kg.), the RECOVERY operation is automatically interrupted. To cancel this alarm, charge one or
more A/C systems before recovering any more refrigerant or, using a scale and a D.O.T. tank, charge enough
refrigerant into the D.O.T. tank so that the refrigerant available will be approximately 12 to 15 lbs. This
refrigerant can be reclaimed later should 69789/69789-H need to be re-filled again with refrigerant.
(See Empty Tank Alarm)

NOTE: Do not attempt to charge a new refrigerant tank (blue tank with a single port valve). These tanks are
not D.O.T. approved for refilling and only have a check valve in them that allows refrigerant to leave the tank.
Since these tanks have a check valve and DO NOT have pressure safety devices on them they cannot be

refilled by 69789/69789-H.
NOTE: Never transfer refrigerants to a cylinder or tank unless it is D.O.T. approved for refilling. D.O.T. approval

is indicated by the designation “DOT 4BA” or “DOT 4BW” stamped on a tank’s collar (handle.) If a refrigerant
tank is overfilled, it may explode! Failure to abide by these warnings may cause personal injury or death.

EMPTY TANK ALARM: Beeper and the LCD advise when the quantity of refrigerant fluid contained in the tank is too low. At this time
it will be necessary to bottle fill 69789/69789-H to approximately 12 to 15 lbs of refrigerant in order for the
alarm to clear.

SERVICE ALARM: Service Alarm: The first service alarm; when the total recovered amount of refrigerant reaches 114 lbs, a
beeper will sound and the LCD will display SERVICE ALARM. To clear the alarm, press F2.
After the first alarm is cleared, filters should be purchased to have ready when 69789/69789-H requires that
the filters be replaced. The second service alarm; when the total recovered amount of refrigerant reaches
132 lbs, a beeper will sound and the LCD will display ENTER FILTER CODE. There will also be 10 dots along
the bottom of the screen. To deactivate the alarm, the filters will need to be replaced (see page 34 Replacing
the dryer filters.)

NOTE: It is good practice to change the Vacuum pump oil when the filters are being changed. (see page 32,
Vacuum Pump)

LOW REFRIGERANT ALARM: Beeper and the LCD advise when the charging quantity set exceeds the amount of refrigerant available. The
minimum quantity of refrigerant is 4.50 lbs. If the gas available minus the charge quantity equals less than

4.5 lbs, 69789/69789-H will interrupt the attempt to charge and notify the operator that there is insufficient
refrigerant. At this time it will be necessary to tank charge 69789/69789-H to approximately 12 to 15 lbs of
refrigerant in order to perform a charge. For instance, if the gas available is 9.50 lbs and the charge
quantity is 1.80 lbs, then 9.50 lbs minus 1.80 lbs equals 7.70 lbs. 7.70 lbs is greater than 4.50 lbs so
69789/69789-H will perform the charge. If the gas available is 5.90 lbs and the charge quantity is 1.80 lbs,
then 5.90 lbs minus 1.80 lbs equals 4.10 lbs. 4.10 lbs is less than 4.50 lbs, so 69789/69789-H will not
charge and will let the operator know that there is insufficient refrigerant available.

PRELIMINARY OPERATIONS

Check that the main switch (Fig. 6-I, page 8) is set to 0. Check that all the machine valves are closed. Connect the machine to the electrical supply
and switch on. Check that the vacuum pump oil level indicator shows at least one-half full. If the level is lower, add oil as explained in the ROUTINE
MAINTENANCE section (page 32.) Check that in the new oil container (Fig. 6-D, page 8) there are at least 3.4 oz. (100 cc) of the oil recommended by
the manufacturer of the vehicle A/C system. Check that the oil level in used oil container (Fig. 6-M, page 8) is less than 6.7 oz. (200 cc.) Check the
machine’s data display to be sure there is at least 9 lbs (4.08 kg) of refrigerant in the tank. Should this not be the case, fill the on-board machine
tank from an external tank of appropriate refrigerant following the procedure described in the ROUTINE MAINTENANCE section (page 32.)

WARNING:
DO NOT STOP THE RECOVERY PROCESS. Stopping the recovery process will definitely cause damage to the Compressor and perhaps other
components. It will also cause the machine to fill up with unprocessed liquid refrigerant which will disable the machine from further use.
Damage due to STOPPING THE RECOVERY PROCESS could void the warranty.

AUTOMATIC PROCEDURE

In the automatic mode, all the operations are performed automatically: recovery and recycling, oil discharge, vacuum, new oil reintegration, and
charging. The values for the quantity of gas recovered, quantity of oil recovered, vacuum time, quantity of oil reintegrated, and quantity of
gas charged into the system are automatically printed at the end of all operations.

Connect the hoses to the A/C system with the quick-connect couplings, bearing in mind that BLUE must be connected to the low pressure side and
RED to high pressure. If the A/C system is equipped with a single quick-connect coupling for high or low pressure, connect only the relative hose.

Check that the high- and low-pressure taps are closed. Start the vehicle engine and switch on the air conditioner. Allow both to run for about 5 to 10
minutes with the passenger compartment fan at full speed. THEN TURN OFF THE A/C SYSTEM AND SHUT-OFF THE VEHICLE’S ENGINE.
