Introduction

Thank you for purchasing the CPS Mach 1 AR212TR series unit. CPS is dedicated to give you the fastest and most reliable equipment to meet all your mobile A/C service requirements. In doing this CPS has integrated its latest technology and incorporated state of the art features while improving reliability and speed.
The AR212TR series is a Multi-refrigerant that automatically
recoverys/recycles/evacuates and recharges. The AR212TR is designed for small as well as larger mobile A/C systems. The AR212TR is equipped with a built in pump down valve to clear out the refrigerant from the last job. Simply hook up the service hoses, choose the operation and allow the unit to perform its job until it automatically shuts off. Then follow the pump down directions to prepare the unit for the next refrigerant.
The AR212TR series utilizes a single pass coalescing and distillation recycling system, which means that when the AR212TR recovers it also recycles. Thus the recovery tank always contains the cleanest refrigerant possible for future use.
The Mach 1 AR212TR series utilizes a 450 W compressor, non-restrictive control valves and large ported solenoid valves to make it one of the fastest refrigerant handling systems in its class.
The AR212TR utilizes a unique compressor assist charging method that does not
require a heater blanket. This gives the unit one of the fastest recharge rates of up to 1.5 kg per minute. The unit will even notify you if there is not enough refrigerant in the recovery tank to perform the charging operation!

The following are additional features:

• Integrated Manifold Gauge Set. Visually see how the mobile A/C system is operating.
• A highly accurate electronic charge scale has been integrated into the AR212TR control system
• Hour meter give the user immediate information on the status of the moisture filtration system.
• Tank overfill protection is provided by the electronic scale software and hardware.
•  Automatic high-pressure shut-off with indication light.
• Modular component design and a hinge front panel allow for easy service access.
• Built in Oil and/or Dye vacuum injection with a 480-ml (16-oz) reservoir.
• The unit has the ability to recharge large amounts of refrigerants.
• One bolt-external filter access system allows the user to change the filter core in less than 5 minutes.
• Replace only the filter core. This will greatly reduce the maintenance cost of filter changes.
• The control valves utilize CPS’s fully ported Teflon valves.
• Heavy-duty construction, powder coated steel cabinet mounted onto a 2.5 cm tubular steel wrap around frame.
• 25 cm pneumatic rear wheels and 10 cm swivel casters give this unit excellent maneuverability under the worst of conditions.
• Recovers and Evacuates through both the high and low side service hoses.
• Automatic Oil Drain System.
• Acculevel Compressor oil level system, maintains the proper oil level in the AR compressor.

   – Blue 8 ft service hose w/low side service valve
   – Operation Manual
   – 27liter.Recovery Tank (separate box) Note: Each type of refrigerant recovered will need its own recovery tank.
   – Two 3/16 Cotter Pins

3. Pull the 10” Wheel as far as it will move. It should move about 3 cm. Place the provided 3/16 Cotter pin into the
   hole though the axle just behind the wheel hub. Repeat this procedure for the other side. This will extend the
   wheelbase to 56 cm.

4. Attach the Blue 8 ft service hose w/Low Side Service valve onto the low side manifold fitting just below the Low Side
   Pressure Gauge and Valve. Place the Low Side Service valve onto the adapter on the back of the unit for storage.

5. Attach the Red 8 ft service hose w/High Side Service valve onto the high side manifold fitting just below the High
   Side Pressure Gauge and Valve. Place the High Side Service valve onto the adapter on the back of the unit for
   storage.

6. Inspect the unit for loose hoses. Also make sure that the tank is centered on the scale platform so that it does not
   touch any of the protective framework. Note: The load cell will not weigh accurately if it is touching the
   framework.

7. Check the oil level in the Vacuum Pump. Make sure the vacuum pump power switch is in the “ON” position, the
   vacuum pump hose is properly connected and the vacuum pump valve is open. Also check that the vacuum pump
   power cord is properly plugged into the receptacle on the bottom of the unit. Read vacuum pump manual for
   further maintenance issues.

8. If desired, please add OEM recommended A/C oil and /or dye to the Oil Injection Bottle. Do not use Oil Injection

Recovery Operation

This unit features a single pass coalescing-distillation recycling process. As the refrigerant is being recovered, it is also being recycled to meet or exceed SAE J1990 (R-12) standards. Please read the following instructions on the recovery
process. Plug the power cord into the appropriate power supply. Turn the Power switch to “I” (On) position. The unit’s LCD will begin a self-test. Once complete the LCD will display the current refrigerant weight in the recovery tank.

Connect the Low and High Service fitting on the end of the 8 ft blue and redservice hoses to the low and high side service ports of the mobile air conditioning system.

Open the Low and High Side Service ball valves. You can now run the mobile A/C system to read system operating pressures. Once diagnosis is complete, turn off mobile A/C system.

There must be a minimum pressure of 7 psig in the mobile A/C system (if
below 7 psig, there maybe excessive air and very little refrigerant to recover)
to continue with the recovery process.

Open the Low and High Side Manifold valves.

Select “RECOVER” on the Mode Selector Switch

Push “CLEAR” key until the scale reads zero. The LCD
will read “RECOVERED REFRIG”, “0kg 000g”.
The LCD will display the amount of refrigerant
recovered throughout the recovery process.
Push “START 1” switch to begin the recovery process

The unit will run until the “RECOVERY COMPLETE”
light (green) energizes. After waiting 5 minutes check
the Low and High Side Pressure gauges to verify a slight
vacuum pressure.

Note: If the pressure rises above 5 psig, the unit will
automatically restart. This will repeat until the
pressure remains below 5 psig.

Once the recovery process has been completed, the oil removed from the mobile A/C system wilautomatically drain into the 16 oz bottle. Please record the amount removed. The procedure to re-inject oil will be discussed in the EVACUATION section. Once measured, please dispose of the oil in accordance with local or federal regulations. If required, also record the amount of refrigerant recovered. The recovery process is complete. Proceed to repair the mobile A/C system.

Evacuation Operation

After the mobile A/C system has been repaired, it will be necessary to evacuate all the non-condensables (NCG’s) and moisture before recharging. After time, moisture and non-condensables can lead to severe damage of an A/C system.
Moisture can create an acid, which will lead to premature material failure, and non-condensables will elevate system pressures, which could reduce the life expectancy of the system compressor.

It is necessary to have the “RECOVERY COMPLETE” light (green) on before Evacuation Operation. If the “RECOVERY COMPLETE” light is not on, run the Recovery Operation.

Connect the Low and High Service fittings on the end of the 8 ft blue and red service hoses to the low and high side service ports of the mobile air conditioning system.

Open the Low and High Side Service ball valves

Select “EVACUATE” on the Mode Selector
Switch

MACH 1 AR212TR, AR212TRS Multi-Refrigerant Recovery/ Recycle and Recharge Unit Operation Manual

The vacuum pump will run until the Vacuum
Timer has expired. Close both the Low and High Side Manifold valves.

Check the Low and High Side gauges to verify vacuum pressure. Check with the OEM for vacuum level recommendations. Repeat this process if necessary.

Once the proper vacuum level has been reached, proceed to re-inject the A/C OEM recommended oil and/or dye into the mobile A/C system.
Please make sure that there is enough oil in the Oil Injection bottle before
proceeding. Caution: Air could be injected if the oil level in the bottle drops below the 60 ml line. Open the Oil Injection valve slowly. Once the required amount of oil has been injected, close the Oil Injection valve. The unit is now prepared for Charging

Charge Operation

The AR212TR incorporates a highly accurate electronic charging scale. The electronic scale is always active whenever the power switch is on. The AR212TR incorporates a push-pull charging method, which speeds up the charging process
and improves the accuracy. No heater blanket is ever required.

Caution: The Evacuation process should always precede the Charging process. If the A/C system is not properly evacuated, moisture and non-condensables can lead to severe damage of an A/C system. Moisture can create an acid,
which will lead to premature material failure, and non-condensables will elevate system pressures, which could reduce the life expectancy of the system compressor.

Connect the Low and High Service fittings on the end of the 8 ft
blue and red service hoses to the low and high side service ports of
the mobile air conditioning system.
Open the Low and High Side Service ball valves.

Open the Low Side Manifold valve only. The High Side Manifold valve must remain closed. Select “CHARGE” on the Mode Selector Switch. Push “SET” key. Then use the “+” or “-“ keys to set the required charge. Also use the “lb/kg” key to select unit of measure. Push “START-2” key to begin the charging process.

The charging software will check to see if there is enough refrigerant in the tank to complete the charge. In order to start the charge process, the refrigerant in the recovery tank must be greater than the charge amount programmed plus 2
kg. If there is not enough refrigerant to perform the charge process, the LCD will prompt the user that “REFRIGERANT LOW” and the Red Indicator will energize. The user will need to follow the instructions to refill the refrigerant tank before proceeding with charge.

Otherwise the unit will run until the programmed charge weight has been met. The LCD will give the user continuous updates on the charge status. The unit should charge approximately 1 kg. per minute.

Once the charge is complete, close the Low Side Manifold Valve (the High Side Manifold Valve is already be closed). You can now start the mobile A/C system to check the system operating pressures.

Close and remove Low and High Service valves once satisfactory operation is achieved.

Important: Do not move the unit when operating in the Recovery or
Charge Mode. Moving the unit during these processes with cause
weight reading inaccuracies.

Pump Down Procedure

The AR212TR series are equipped with a Refrigerant Pump Down Valve system. This is to be used when changing from one refrigerant (such as R-12) to another refrigerant (such as R-22). It is extremely important to follow these
directions. Failure to do so could result in cross-contaminated refrigerant.

Please follow the directions below for the proper pump down procedure.

Step1: Close the Tank Liquid and Vapor valves. Close the Liquid and Vapor Tank Hose valves. Disconnect both Tank hoses from
Tank. Step 2: Connect the Low and High Service valves on the end of the 8 ft blue and red service hoses to the Pump Down Block located on
the back of the unit. Step 3: Connect the Liquid and Vapor Tank hoses to the Pump Down Block located on the back of the unit.

Step 4: Connect the Auxiliary Hose to the Vapor Port the tank. Open the Tank Vapor valve and the Auxiliary Hose valve. Step 5: Turn the Pump Down Valve to the Pump Down position. Step 6: Open the Low and High Side Manifold valves, Low and High Side service valves, and the Liquid and Vapor Tank Hose valves.
Step 7: Select “RECOVER” on the Mode Selector Switch
Step 8: Push “START 1” switch to begin the recovery process.

Step 11: Push “START 1” switch to begin the evacuation process.
The vacuum pump will run until the Vacuum Timer has expired.
Check vacuum level on Gauges. A minimum of 25”in hg

Step 12: Close the Low and High Side Manifold valves, recovery tank vapor valve, auxiliary hose valve, Liquid and Vapor Hose valves, and Low and High Side service valves.
Step 13: Disconnect Auxiliary hose from tank. Remove tank from unit.

Step 14: Install the next selected refrigerant tank onto the unit.
Make sure that it is centered on the scale.

Step 15: Connect the Liquid and Vapor Tank Hoses to the respective Tank ports. Make sure liquid hose goes to liquid tank port and vapor hose goes to the vapor tank port. Step 16: Open all Tank valves and Tank hose valves. Step 17: Turn the Pump Down valve back to the normal position. Step 18: Check for leaks.

Non-

Condensable Gases

From time to time it will be necessary to purge the recovery tank of non- condensable gases
(NCG’s). The NCG’s are picked up from leaks in a/c systems, service valves left open,
etc…
The best time to check for purging is first thing in the morning before using the unit. This gives the refrigerant time to stabilize.
Use the NCG’s purge table below to determine if the refrigerant in the recovery tank needs to be purged of NCG’s. If purging is required:
1. Open the purge valve. The NCG’s will vent though the purge port.
2. Once the pressure of the tank falls below the NCG Gases purge table, close the purge valve.

Routine Maintenance

Filter Maintenance- the Mach 1 AR212TR is equipped with a 650 ccm solid core desiccant cartridge. This filter
drier cartridge should be changed if:

1. The Moisture Indicator turns from purple to a red color. See the color ring around the Moisture Indicator for a
   direct comparison of moisture levels in the refrigerant. Replace when “wet” refrigerant is indicated.
   -or-
2. The unit has been used for 50 hours as indicated by the hour meter.

Replace the filter cartridge as follows:

Danger: Always assume that high-pressure refrigerant exists in the Filter Shell. Failure to do so may result in bodily injury.

1. Run the unit per the Recovery procedure. Note: Leave the Low and High Service valves closed.

2. The unit will automatically shut-off when the vacuum switch has been activated. This will remove any residual
   refrigerant on the low side of the unit.

3. Open the Oil Drain valve before removing the Filter Access Cap. If there is any remaining refrigerant pressure, it
   will be vented through the Oil Drain valve.

4. Loosen the Filter Access Cap as shown in Figure 1. Rotate the Cap counter-clockwise and pull outward. The cap
   will release once the quick release mechanism aligns with the flange on the Filter Shell.

5. Remove the spring-loaded insert to expose the Filter Drier Core as shown in figure 2.

6. Remove and dispose of the old Filter Drier Core as shown in figure 3.

7. Replace filter cartridge with CPS part # ARXF

8. Reassemble the remaining components. Make sure the rubber gasket is properly placed in the Filter Shell flange.

9. Remember to close the Oil Drain valve once reassembly is complete. !After replace the filter cartridge, it is

necessary to conduct a leak test for the complete unit !! Unit is now ready for operation.

Vacuum Pump Oil- the Mach 1 AR212TR is equipped with a vacuum pump. It may be necessary to occasionally add additional vacuum pump oil. View the oil level through the sight glass provided on the vacuum pump.

If it is noticed that the vacuum pump is not performing as it did when new, completely drain and refill with new vacuum pump oil. Contaminants in the vacuum pump oil will greater effect the performance.

Use the Vacuum Pump manufacturers recommended vacuum pump oil.
Please read the vacuum pump operation manual for further maintenance details.

End of the Day Maintenance- as a matter of precaution, close both recovery tank valves. Close all other valves. Please note that CPS does not take responsibility for lost refrigerant.

Trouble Shooting Chart

Problem: The unit will only pull down to 0 pressure or a slight vacuum.
Solution: Make sure that both the Oil Drain Valve and Oil Injection Valve are fully closed. If left open in the during the recovery operation, air will be pulled through the valve. Solution: Make sure that both the Low and High Side Service Hoses are leak tight.

Problem: The unit fails to charge the automobile. Message on LCD will read “CHECK CONNECTIONS”.
Solution: Make sure that both tank valves are open. Also check that the liquid hose is connected to the liquid port of
the tank. Solution: Make sure the High and Low Service valves are open.

Problem: The unit completed its charge operation, but it seems that the automobile is low on charge.
Solution: It is crucial that the High Side Manifold valve be closed when charging. If left open some of the charge will reenter the unit; thus a shortage will result in the automobile A/C system. Repeat recovery, evacuation, and charge
operations.

Problem: In charge operation, after pushing the START-2 key the LCD reads “LOW REFRIGERANT” and
will not charge. Solution: The unit’s refrigerant tank needs to contain a minimum of 2 kgs plus the charge amount before charging. Use the refill procedure to add additional refrigerant to the tank.

Problem: During the recovery operation the unit is shut-off by the high- pressure switch. This should be noted by the red light energizing with no LCD message.
Solution: Make sure that both tank valves are open. Push the HPCO reset button to reset unit.

Problem: During the recovery operation the unit is shut-off by tank overfill safety system. The red light
energizing and a LCD message “TANK FULL” will note this condition.
Solution: It will be necessary to charge approximately 5 lbs. into an empty refrigerant cylinder. Connect the High Side Service valve to the tank liquid port and the Low Side Service valve to the tank vapor port. Follow the directions for
the charge operation.
