STEPS:
1. Turn off all electrical or mechanical power to the refrigerant device to be evacuated.
2. Make proper hose connections: Connect refrigerant hoses to recovery cylinder, unit, and the refrigerant system as shown in Figure 1. NOTE: You must use an external filter drier in the suction line in order to meet the conditions of the unit warranty.
Caution: If the 80% shutoff option is not used, a scale must be used to monitor the refrigerant level in the recovery cylinder.
NOTE: Although the Model 3700 was designed to handle liquid slugging, pumping large amounts of liquid over extended periods of time will reduce the life of the compressor. If large amounts of liquid are present, it is recommended that you use the liquid push-pull method of recovery prior to vapor recovery operations (See Figures 3 & 4).
3. Place the inlet and purge ball valves in the CLOSED position and the outlet valve is in the OPEN position. Open the DOT recovery cylinder liquid valve (See Figure 2).
4. Turn the system switch to the ON position. The LED status display will indicate
“SYSTEM ON”.
NOTE: The system fan is on whenever the system switch is in the
ON position.
5. Regulate the inlet port ball valve when liquid refrigerant is present.
WARNING: A “knocking” sound coming from the compressor indicates too much liquid is entering the compressor. The inlet ball valve must be regulated as shown in the shaded region until this knocking sound stops, otherwise compressor damage could occur. Pumping liquid when the compressor is knocking will damage the compressor and will reduce the compressor life and will
void the compressor warranty.
6. Monitor the LED status display. The unit will shut off automatically when the proper vacuum level is achieved and the status display will flash “EVACUATION COMPLETE”

Indicates that the unit has shut down because the system being evacuated has reached 13" HG (The evacuation is complete). During liquid push-pull operations the system will not be pulled into a vacuum.
NOTE: A small amount of inlet pressure might be needed to reset the vacuum switch, this is normal.
Indicates that there is a high pressure condition that must be corrected. Check for restrictions or a full recovery cylinder.
Correct problem and turn system switch to the OFF position.
Repeat steps 3-6.
Indicates that the recovery cylinder is full (if the 80%
Automatic Tank Full Shutoff Option is installed). Change the recovery cylinder and repeat steps 3-6.
7. Purge the system by positioning the inlet and purge ball valves to the PURGE position
(both pointing DOWN). CAUTION: Never turn the purge valve while the compressor is running or severe compressor damage could occur. Ensure the power switch is in the off position before turning the purge valve. If the unit is manually or automatically turned off before the evacuation is complete, repeat steps 3-7.
NOTE: If the circuit breaker trips wait 10 seconds, reset circuit breaker and go to step 3. If the compressors thermal overload trips, wait 16 to 30 minutes before restarting.

NFORMATION
Attention: Before attempting the following liquid push-pull recovery operations, please review this page.
It may not be possible to recover liquid refrigerant from some types of refrigeration equipment.
A scale or liquid sight glass can be used to determine when all the liquid is recovered. The unit will not pull a vacuum using the push-pull liquid recovery operation.
To finish the recovery operation, you must proceed to vapor recovery operations.
Guidelines
If any of these conditions are present in the system being evacuated, liquid push pull operations may not be practical and vapor recovery operations should be performed.
• The equipment contains less than 15 lbs. of refrigerant.
• The equipment is a heat pump or other system with refrigerant flow that would prevent you from isolating the liquid.
• Equipment has an accumulator between the service ports used in the liquid recovery process.
• Liquid refrigerant migration has occurred and the location of the liquid is unknown.
• The refrigerant tubing design on the equipment does not allow for a solid column of liquid refrigerant to be formed.
Direct Liquid Recovery Operations
All compressors are designed to compress gases. Normally compressors are not capable of pumping non-compressible fluids such as liquid refrigerant; however, the Model 3700’s compressor head and valves have been specially engineered to enable it to handle liquid directly. This feature makes the 3700 easier to use by minimizing the need to monitor incoming refrigerant vapors and reduces compressor failures due to liquid slugging.
It is important to remember that the 3700 is a compressor and not a liquid pump. When large amounts of liquid are present, the liquid push-pull method of recovery should be used.
Using the 3700 to pump large amounts of liquid refrigerant over a long period of time will reduce the compressor life.
WARNING: A “knocking” sound coming from the compressor indicates too much liquid is entering the compressor. The inlet ball valve must be regulated as shown in the shaded region until the knocking sound stops, otherwise compressor damage could occur.
Pumping liquid when the compressor is knocking will damage the compressor and will reduce the compressor life.
This will void the compressor warranty.
A sudden slug of liquid into the compressor may cause a sudden spike in pressure and cause the high pressure safety shutoff switch to shut the compressor off. If this happens, you must clear the liquid from the compressor before you can restart the compressor. To prevent this from happening, always open the inlet valve slowly when starting a recovery job. Opening the inlet valve quickly could allow a slug of liquid to enter the cylinder and cause the high pressure switch to shut the system down.

ROCEDURES
STEPS:
Liquid push-pull operations are performed by using hot compressor gas to push liquid refrigerant out of a system. The purge valve accomplishes this by re-directing the hot compressor gas around the condenser. See the diagram on top of the unit for hose connections.
1. Turn off all electrical or mechanical power to the refrigerant system to be evacuated.
2. Make proper hose connections. Connect the discharge hose from the outlet port to the low pressure side of the system you are servicing. Connect a hose between the liquid port (receiver or condenser) on the system being serviced and the liquid valve on the DOT recovery cylinder. Connect the inlet hose from the DOT recovery cylinder vapor valve to the 3700’s inlet port. See Figure 3 for a hose connection diagram.
NOTE: You must use an external filter drier in the suction line in order to meet the conditions of the unit warranty. Caution: If the 80% shutoff option is not used, a scale must be used to monitor the refrigerant level in the recovery cylinder.
3. Place the inlet and purge valves in the LIQUID PUSH-PULL position. This will allow hot compressor gas to bypass the condenser. OPEN the liquid and vapor valves on the cylinder (see Figure 4).
4. Open the outlet ball valve and the vapor and liquid valves on the DOT recovery cylinder.
5. Turn the system switch to the ON position. When all liquid refrigerant is recovered, turn the system switch to the OFF position. NOTE: Liquid push-pull operations do not pull a vacuum on a system. You must perform a vapor recovery operation in order to pull the system down to the required vacuum level.
6. Monitor the LED status display.
The “SYSTEM ON” indicator should be ON during normal operations.

Indicates that the recovery cylinder is full (if the 80% Automatic Tank
Full Shutoff Option is installed). Change the recovery cylinder and repeat steps 3-6.
7. Turn the system switch to the OFF position when all liquid is recovered. The liquid recovery operation is complete when there is no more liquid present in the system. This can be verified by using an in-line sight glass to monitor the refrigerant flow in the line. NOTE: The unit must be manually shut off during all liquid recovery operations.
8. Proceed to vapor recovery operations to complete the recovery procedure. If the unit is manually or automatically turned off before liquid recovery is complete, repeat steps 3-8. NOTE: If the circuit breaker trips wait 10 seconds, reset circuit breaker and go to step 3. If the compressors thermal overload trips, wait 16 to 30 minutes before restarting.

PERATIONS
The Model 3700 is equipped with a pump-down purge valve that allows the technician to pump down or evacuate the 3700 before proceeding to the next recovery operation. This procedure not only eliminates cross contamination, but also conserves refrigerant. Follow the steps below to ensure your pump down operation is performed correctly.
STEPS:
1. After recovery operations are complete and the system switch is in the OFF position:
FIRST - Place the inlet valve in the PURGE position
SECOND - Place the purge valve in the PURGE position
THIRD - Place the outlet valve in the OPEN position as illustrated below.
It is important to turn the valves in this order to ensure the compressor properly equalizes.
2. Turn the system switch to the “ON” position. The LED status display will indicate
“SYSTEM ON”.
NOTE: If the compressor fails to start, cycle the purge valve from the
RECOVERY to PURGE position to reduce the pressure difference shown on the system’s gauges.
3. Allow the unit to run until it shuts off automatically. The LED status display will turn off indicating that the purge operation is complete.
4. Turn the system switch to the OFF position and turn the outlet valve to the “CLOSE” position. Close the inlet and outlet valves on the DOT recovery tank.
During the pump down operation, the 3700’s compressor pulls the entire system and discharge hose into a vacuum and discharges the gas directly out of the discharge port leaving no more than 1/4 ounce of refrigerant left the system.
CAUTION: Never turn the purge valve while the compressor is running - severe compressor damage may occur.
