Safety Precautions

Explanation of Safety Signal Words Used in this Manual

The safety signal word designates the degree, or level, of hazard seriousness.

DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death or

serious injury.

WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or

serious injury.

CAUTION: Indicates a potentially hazardous situation which, if not avoided, could result in minor or

moderate injury. CAUTION: Used without the safety alert symbol indicates a potentially hazardous situation which, if not

avoided, could result in property damage. These safety messages cover situations Robinair is aware of. Robinair cannot know, evaluate, or advise as to

all possible hazards. The user must verify that conditions and procedures do not jeopardize personal safety.

Explanation of Safety Decals Used on the Machine

Carefully read the instructions.

Do not use in open air in case of rain or high humidity.

Wear gloves.

Wear protection goggles.

Alternating voltage.

Grounding protection.

Electrical shock hazard.

WARNING: To prevent personal injury,

ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THE MACHINE. Before operating the machine, 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 this manual, operating instructions and safety precautions must be read and discussed in the operator’s native language.

USE THE MACHINE AS OUTLINED IN THIS MANUAL. Using the machine in a manner for which it was not designed will compromise the machine and nullify the protections provided.

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. Do not overll the internal storage vessel (ISV). Overlling can cause explosion resulting in personal injury or death. Do not recover refrigerants into nonrellable containers; use only type-approved rellable containers that have pressure relief valves.

HOSES CAN CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant can cause personal injury, including blindness and frozen skin. Wear protective equipment, including goggles and gloves. Disconnect hoses using extreme caution. Ensure the phase is complete before disconnecting the machine to prevent the release of refrigeration to the atmosphere.

AVOID BREATHING A/C REFRIGERANT AND LUBRICANT VAPOR OR MIST. Exposure can irritate eyes, nose, and throat. To remove refrigerant from the A/C system, use only equipment certied for the type of refrigerant being removed. 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.

DO NOT DISPERSE REFRIGERANT INTO THE ENVIRONMENT. Prevent the possible presence of refrigerant in the working environment.

TO REDUCE THE RISK OF FIRE, do not use the machine in the vicinity of spilled or open containers of gasoline or other ammable substances.

TO REDUCE THE RISK OF FIRE, do not use an extension cord. An extension cord can overheat and cause re. If an extension cord must be used, use the shortest possible cord with a minimum size of 14 AWG.

TO REDUCE THE RISK OF FIRE, do not use the machine in the vicinity of ames and hot surfaces. Refrigerant can decompose at high temperatures and free toxic substances to the environment that can be noxious to the user.

TO REDUCE THE RISK OF FIRE, do not use the machine in environments containing explosive gases or vapors. TO REDUCE THE RISK OF FIRE, protect the machine from conditions that can cause electrical failure or

other hazards relating to ambient interaction.

CAUTION—DO NOT PRESSURE TEST OR LEAK TEST EQUIPMENT AND/OR VEHICLE AIR CONDITIONING SYSTEMS WITH COMPRESSED AIR. Some mixtures of air and refrigerant have been shown to be combustible

at elevated pressures. These mixtures, if ignited, can cause injury or property damage.

HIGH VOLTAGE ELECTRICITY INSIDE THE MACHINE HAS A RISK OF ELECTRICAL SHOCK. Exposure

can cause personal injury. Disconnect power before servicing the machine.

Safety Precautions

NEVER LEAVE THE MACHINE LIVE IF AN IMMEDIATE USE IS NOT SCHEDULED. Disconnect the electrical

supply before a long period of inactivity or before internal maintenance is performed.

DO NOT MODIFY THE PRESSURE RELIEF VALVE OR CHANGE THE CONTROL SYSTEM SETTINGS.

Using the machine in a manner for which it was not designed will compromise the machine and nullify the protections provided.

Additional health and safety information can be obtained

from refrigerant and lubricant manufacturers.

Hose Equalize

A/C Service Function

This A/C Service Function menu item directs the user through clearing the service hoses after running the A/C system to perform diagnostics. Use this function when the service hoses were connected, but no refrigerant was charged into the system.

Following hose equalization prompts prevents leaving part of the vehicle’s refrigerant charge in the service hoses, a situation which can cause a loss of A/C performance on lower-capacity systems.

1. Place the vehicle gear selector in park or neutral, with the

emergency brake ON. Connect the low-side hose to the A/C system; disconnect the high-side hose.

2. Start the vehicle. Set the A/C system at maximum delivery. During this operation, the high side and low side are

connected internally, allowing the majority of refrigerant to be pulled back into the A/C system’s low side.

3. When prompted, disconnect the low-side hose and turn

off the vehicle. Press OK.

4. The machine performs an internal clearing of its plumbing,

and sounds an alarm when complete. Press OK to exit.

A/C Service Function

System Flush

This machine provides a method of removing oil by forcing liquid refrigerant through an A/C system, or components of an A/C system. A special ushing adapter (purchased separately) accesses the A/C system at the compressor block. After ushing, the refrigerant is recovered by the machine and ltered by the recycling circuit, returning it to SAE purity levels.

A/C systems vary and may require the adapting and ushing of individual components. Refer to service bulletins as needed during this procedure.

WARNING: To prevent personal injury while working with refrigerant, read and follow the instructions and warnings in this manual, and wear protective equipment such as goggles and gloves.

Setup

1. Verify the oil drain bottle on the front of the machine is empty. See Figure 6. Recover refrigerant as outlined in this manual.

2. Close service coupler valves and disconnect hoses from vehicle access ports.

3. Close the valve on the external source tank.

Note: During this procedure, up to refrigerant is charged into the vehicle A/C system. If the

ushing cycle is stopped before it is complete and the

external source valve is open, the machine automatically adds refrigerant to the ISV, and there will be no room to

recover the refrigerant used for ushing.

4. Remove the A/C system expansion device, and reconnect the ttings to create a bypass.

5. Disconnect the refrigerant lines from the vehicle compressor.

6. Attach the compressor block adapter (from the ushing kit) to the system side of the compressor block.

3.5 kg (7.7 lbs.)

Notes:

The machine must have at least 4.6 kg (10.1

•

lb.) of refrigerant available in the ISV (as indicated on the display) for charging.

If the ush process is interrupted by an

•

accidental power-down or other fault, use the recovery mode to remove the refrigerant from the vehicle.

7. Congure the block connectors to provide forward- or back-ushing of the refrigerant, which ows from the machine through the red high-side connection hose. Open the red service coupler.

8. Connect the lter housing to the desired return side of the adapter block and to the blue low-side hose. Open the blue service coupler.

9. Verify that a ushing lter is correctly installed in the ushing lter housing. Open the isolation valve on the hose.

menu.

2. Perform the VIN entry function

3. Select START to accept the default ush time of 10

minutes, or enter the desired ush time using the keypad

and select START.

4. The following tests are automatic and performed as

required by SAE J2843:

• vacuum that runs 5 – 20 minutes to achieve the correct level

• 5-minute vacuum rise test

• 15% charge

• manual leak test using a leak detector certied to

SAE J2913

Notes:

• J2843 leak testing is intended to nd a gross leak before charge, for safety reasons. It is not intended to take the place of other established leak test practices.

• The 15% charge is automatically recovered before recharging the programmed amount.

• To avoid false failures, the temperatures of the vehicle system and the recovery machine should be within ± 5°C.

WARNING: Do NOT disconnect service

couplers during the ushing process. Refrigerant could spray out of the ttings,

and exposure may cause personal injury.

CAUTION: To prevent vehicle damage, use an oil inject tool to replace the system oil. Flushing removes all oil from the system except what remains in the compressor.

Refer to the vehicle service manual for specic vehicle instructions.

5. The machine ushes the system for the designated length of time, and then enters a recovery mode.

6. Oil that has been collected drains into the graduated oil drain bottle. Remove the bottle and measure oil.

Dispose of oil according to the laws in your jurisdiction. It is the responsibility of the user to determine if a material is a hazardous waste at the time of disposal.

7. When the machine displays

FLUSH COMPLETE

Close service couplers, remove hoses, and reassemble the vehicle’s A/C system to its original state.

8. Open the valve on the source tank.
