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.

NOTE: Stopping the recovery phase before the oil is discharged may damage the recovery/recycle machine’s compressor.

Upon completion of discharge, the machine will check for the presence of air in the tank, and if it’s necessary, purge the non-condensable gases.
The alarm will sound continuously and the display will show:

The Recovery/Recycle machine will automatically purge non-condensable gases (NCGS) if excess NCGS are detected at the end of recovery. Allow
the unit to complete this procedure, eliminating the chance of NCGS being charged to the AC system.

NOTE: Charging may not run to completion due to pressure balance between the internal refrigerative storage tank and the A/C system. If this occurs,
close the high pressure valve (leaving the low-pressure side open), start the vehicle and switch on the A/C system. The unit is equipped with a tank
heater to limit this occurrence. When the charging operation is complete, the machine will display the following dialog boxes:

ASSISTED PROCEDURE

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.

In the assisted procedure mode, all the operations can be performed individually. 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 each single
operation.

Open the high and low pressure taps on the machine and press the START to begin the refrigerant recovery/recycling phase. During this phase, the
graphic display will show the quantity of refrigerant recovered. The machine checks whether or not there is air in the bottle and, if necessary, purges
the non-condensable gas. The alarm will sound continuously and an AIR PURGE warning will be displayed. The machine will automatically discharge
any non-condensable gas. Allowing the machine to fully complete the procedure will reduce the risk of return flows, which may cause excessive
non-condensable gas to be recharged into the air conditioning system. Upon completion of recovery, the machine will stop and discharge, while
automatically displaying the used oil extracted from the A/C system during the recovery phase. The oil discharge operation lasts 6-14 minutes. If any
residual refrigerant in the A/C system should increase in pressure during this phase, the machine will automatically begin recovering the refrigerant.

VACUUM

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

ROUTINE MAINTENANCE

VACUUM PUMP

Perform the operations listed below on a routine basis in order to ensure the best operation of the vacuum pump:
When filling or replacing the pump oil, use only the oil recommended by the manufacturer.

FIG. 8

OIL FILL - (NEW MACHINE)

This vacuum pump has been tested at the factory and shipped with only trace amounts of oil. OIL MUST BE ADDED BEFORE OPERATING! Failure to
add oil will damage the cartridge and void warranty.

NOTE: Make sure the oil drain valve located below the front casing is closed before attempting to add oil (Fig 8-3.)

32

1) Disconnect the machine from the electrical supply.

2) Remove the rear cover (6 screws.)

3) Unscrew the oil fill/muffler plug (Fig 8-2.)

4) Oil Bottle: A) Remove oil bottle cap
B) Remove the silver foil
C) Attach the filling top (be sure to remove the red cap) (Fig. 8-5.)
D) Attach the filling hose (Fig. 8-6.)

5.) Slowly add oil until oil level rises to the top of the oil level line. Do not overfill with oil! (Fig 8-4.)

6.) Replace the oil fill/muffler plug (Fig 8-2.)

7.) Re-install the rear cover (6 screws.)

CHECKING OIL LEVEL

The oil level in the sight glass should be between the max and min line (Fig 8-4.) If oil level falls below the MIN line add oil per oil fill instructions.

OIL CHANGE

The vacuum pump oil must be replaced:

1) Every 120 working hours, or

2) When the filter/dryers are replaced, or

3) At the beginning or end of every season, or

4) Whenever the oil changes color due to absorption of moisture.
Before beginning the oil change procedure, obtain an empty 16 oz. (1 pint) or larger container in which to collect the used oil.

1) Disconnect the machine from the electrical supply.

2) Remove the rear cover (6 screws.)

3) Unscrew the oil fill/muffler plug (Fig 8-2.)

4) Unscrew the drain plug (Fig. 8-3.)

5) Allow all the oil to run out into a disposal container (drain clearance is less than 3.95 inches.)

6) Close the drain plug (Fig. 8-3.)

7) Pour in new oil through the fill hole until the level rises to the midpoint on the indicators (Fig. 8-4.)

8) Replace the oil fill/muffler plug (Fig. 8-2.)

9) Replace the rear plastic cover on the machine (6 screws.)

NOTE: When changing the vacuum pump oil, dispose of used oil as per federal, local and state regulations.

REPLACING THE DRYER FILTERS

Replace the filters when the machine alerts you. Replace the filters only with
Mastercool part numbers: 69788-FLTRPK. When changing the filters you will need
a filter code. To obtain a filter code, please call Mastercool Inc. Technical Service at
888-825-6989.

LOCK OUT: If you are changing the filters because of the Second Service alarm (see
page 10) and has locked out 69789/69789-H, then a filter code will be needed to
re-set 69789/69789-H. Before changing the filters, call Mastercool Inc. Technical
Service at 888-825-6989 to get the filter code.

NO LOCK OUT: If the filters are being changed at an unscheduled time, no filter
code will be needed to continue operating 69789/69789-H. Only when the machine
reaches the pre-programmed recovery quantity of 132 lbs will it lock out. Once the
machine is locked out, the filter code will be needed to re-set the 69789/69789-H.
(See LOCK OUT)

To change the filters, proceed as described below (refer to Fig. 9):

1) Disconnect the machine from the electrical supply.

2) Wear protective gloves and glasses.

3) Remove the rear plastic cover from the machine (6 screws.)

4) Close both of the valves on top of tank.

5) Close the valve (Fig. 9-1) under the filter (Fig. 9-4.)

6) Connect the low pressure quick-connect coupling to the male connector
(Fig. 9-2) under the filter (Fig. 9-4.)

7) Connect the machine to the electrical supply and turn the machine on.

8) Put in the filter code. (Only if locked out) To put in the filter code, you will need to
use the down arrow key to move the cursor to the next character. To input a letter, continue to press the same number with the corresponding

letter until the desired letter appears. Once the entire code is showing on the screen, press the F4 key.

9) Using Assisted Procedure, start a recovery operation (NOTE: the valve under the low pressure filter [Fig. 9-3] should be open).

10) When oil draining is reached, immediately close the valve (Fig. 9-3) under the filter (Fig. 9-5) and turn the machine off.

11) Disconnect the machine from the electrical supply.

12) Disconnect the low pressure quick-connect coupling from the connector (Fig. 9-2) under the filter (Fig. 9-4).

13) Replace the filters. IMPORTANT: The filter replacement must be performed as quickly as possible in order to avoid possible contamination by
moisture in the ambient air.

14) Open the valve (Fig. 9-1) under the filter (Fig. 9-4) and the valve (Fig. 9-3) under the filter (Fig. 9-5).

15) Open both valves on top of the tank.

16) Connect the machine to the electrical supply and turn the machine on. (Leave the rear cover off at this time)

17) Press F1 when the machine displays “INTERRUPTED, F1: TO CONTINUE.”

18) Press F2 when the machine displays “ERROR SYSTEM EMPTY.”

19) Tank charge about 1 lb (-500g) of refrigerant to charge the machine circuit.

20) While the machine is recovering, use an electronic leak detector to check the seal on the connections that were opened to replace the filters. Re­ tighten if necessary.

21) Turn the machine off and replace the rear plastic cover on the machine. (6 screws)

22) The machine is now ready for normal use.

FILLING THE NEW OIL CONTAINER

It is good practice to fill the oil container whenever the oil level falls below 3.4 oz (100 cc) in order to guarantee that there will be sufficient oil for
topping off during successive operations. Always refer to the information provided by the A/C system manufacturer for oil specifications (oil is not
supplied.)

Remove the new oil container from its holder. Unscrew the container while holding the cap in place. Fill the new oil container with the correct
quantity of oil, of suitable type and grade. Screw the new oil container back on and replace the new oil container in the holder.

EMPTYING THE USED OIL CONTAINER

This operation must be performed whenever the oil level exceeds 6.7 oz (200 cc.)
Procedure: Remove the container from its holder. Unscrew the container while holding the cap in place. Empty the used oil into a suitable container
for used oils. Screw the container back in place while holding the cap in place. Carefully replace the container into its holder. (Dispose of used oil
as per your federal, local and state regulations.)

CHECKING THE SCALE RESPONSE

Turn the unit on and go to the data screen (F3.) Note the Refrigerant Available value. Hang the 500g test weight that was supplied with the machine
from the hook under the scale. (Fig 10-7) The “REF AVAILABLE” should go up by 500g+/-28g, 1.10lb +/-.06lb or 18oz +/-1oz depending on what
units the machine is set at. If the results of the test are not within these specifications, it is recommended that the scale be re-calibrated. The scale
re-calibration should be done by a qualified Service Technician. The equipment necessary for scale re-calibration is not supplied with 69789/69789­H.
