Mastercool introduces the twin turbo dual complete recovery machine for R134a and R1234yf refrigerants. The 69372 incorporates a spark-free compressor and enhanced features to allow for maximum recovery capacity while at the same time decreasing size and weight. The design of the double piston compressor and cooling by the largest fan and condenser in the market makes the 69372 R134a/R1234yf complete recovery unit the most complete solution to your R134a and R1234yf recovery needs.
Operating Guide for Direct Vapor or Liquid Recovery:
NOTE: Before using this equipment, you will need to determine what refrigerant is in the vehicle that you are working with.
- R134a: If the refrigerant is R134a you will use the LIGHT BLUE tank with the yellow hose marked SAE J2196/R134a
- R1234yf: If refrigerant is R1234yf you will use the GRAY/YELLOW tank with the yellow hose marked SAE J2888/1234yf
- NOT SURE: If you do not know what refrigerant is in the vehicle. Use an Identifier to determine which refrigerant is in the vehicle to prevent cross contamination in either tank
FIRST TIME USE: Each tank is shipped pressurized with dry air. Before the tank can be used for the first time, slow-ly open the vapor (BLUE) valve on the tank by turning the knob counter-clockwise to release the pressure. Once the pressure has been released. Close the vapor (BLUE) valve by turning the knob clockwise prior to connecting the hoses. This step is for the first time only. DO NOT open either valve on the tank when there is refrigerant in it and the tank is not connected to any other part of the equipment. Open the tank valves only when instructed to do so.
NOTE: If the recovery machine shuts off due to a full tank. Close the blue tank valve and the ball valve that is closest to the tank. Turn the machine off. Replace the tank with an empty one. Reconnect the hose. Open the blue tank valve and the ball valve that is closest to the tank. Turn the machine back on.
1. Make sure the ON-OFF switch is off. “0” pushed in. Connect the machine to a grounded power outlet.
2. Turn the inlet (BLUE) valve to the CLOSE position.
3. Turn the center (YELLOW) valve to the RECOVERY position.
4. Assemble the manifold per the included instructions.
5. Connect the YELLOW hose with the shut off valve to the recovery machine inlet (BLUE).
6. Connect the RED coupler to the vehicle HIGH side.
7. Connect the BLUE coupler to the vehicle LOW side.
8. Connect one end of the YELLOW hose with the ball valves to the to recovery machine outlet (RED).
9. Connect the other end of the YELLOW hose with the ball valves to the tanks vapor side (BLUE).
10.Connect the float switch cable to the tank.
11.Open the vapor valve on the tank (BLUE) by turning the knob counter-clockwise.
12.Open both ball valves on the YELLOW hose.
13.Turn the outlet (RED) valve to the OPEN position.
14.Turn the inlet (BLUE) valve to the OPEN position.
15.Open the manifold valves by turning the handwheels counter-clock wise.
16.Turn the machine ON.
NOTE: Observe the operation of the system. In rare instances “SLUGGING” may be apparent (loud compressor noise or high vibration). If this condition is apparent, turn the inlet valve to the LIQUID position. The system can be run con-tinuously in the LIQUID position. It is suggested that the operator periodically turn the inlet valve to the OPEN position and check for proper operation. The best operation of the system is when the inlet valve is OPEN and no “SLUGGING” is observed.
17.When the inlet pressure (BLUE) is 15inHg or more, the recovery is done.
18.To Purge the recovery system. Let the machine continue to run.
19.Turn the center (YELLOW) valve to the PURGE position.
20.Turn the inlet (BLUE) valve to the PURGE position.
NOTE: It may take 1 or 2 minutes to purge the recovery machine of refrigerant. The time depends on how much liquid refrigerant has collected in the machine.
21.When the inlet (BLUE) pressure is 10PSI.
22.Turn the machine OFF.
23.Drain the oil from the recovery machine. See the instructions on the side of the used oil bottle.
24.Turn the machine ON.
25.When the inlet (BLUE) pressure is 15inHg turn the inlet (BLUE) valve off.
26.Turn the machine off.FILTER: This equipment is provided with a sight glass and a spare desiccant filter. Change the filter when the sight glass indicates WET after using and does not return to DRY once the process has ended.
NOTE: The desiccant filter cannot be cleaned or reused.
