Procedure for filling Duracool 12a

Filling Procedures - Cans Duracool 12a 170gr

Read the instructions carefully and look at the warning on the can Duracool®. Can be installed on R12 and 134a systems. Follow regulations and laws according to the regions.


Preparing equipment for use
(the assembly of the equipment must be tightened by hand)

  • Before installing the faucet on the bobbin, make sure that the faucet is fully rotated counterclockwise to avoid piercing the bobbin prematurely

  • Screw the tap on the can

  • At the other end of the hose (the one with the valve) screw the R134a or R12 quick socket connector, depending on the fitting fitted to your vehicle. Please note that only our DC402 fitting has both fittings

Filling procedure

  • Turn on the vehicle and set your air conditioning to maximum in order to start the compressor. Locate the low-pressure service port of the air conditioning system, usually a blue and black plug (never connect to the high-pressure side)

  • Remove the low-pressure cap

  • To connect the quick plug connector to the low-pressure service port. Move the bushing back, while holding the bushing, push the connector onto the low-pressure service port. To ensure a good connection, the ring will return to the original position.

  • Turn the faucet valve clockwise until it pierces the can.

  • Turn the valve counterclockwise to allow the refrigerant to enter the air conditioning system.

  • During this procedure, the can must be inverted.

  • When the compressor reaches on/off every 45 or 60 seconds approximately, it will indicate that you will need to stop the filling procedure. If you use the DC402 charging hose with pressure gauge, the needle must not exceed 45 PSI (top of the blue zone, ideal charging zone), because beyond that you would be overloaded.

  • If the temperature inside the passenger compartment is not cold enough, you will need to add refrigerant in small doses (by opening and closing the valve partially until the proper temperature (50°F) is reached.

  • Be careful not to overload the system, you must leave the compressor running for a few minutes before adding refrigerant.

  • When the filling procedure is complete, turn the faucet clockwise until it comes to a complete stop.

  • To remove the quick socket connector, move the ring back and the connector will pop out on its own.

  • If the can still contains refrigerant, keep the tap on the can. Keep away from an open flame and store it in a well-ventilated area.

  • Affix the identification ticket near the service port.

Filling Procedures - Duracool ® 12A Bottle 5.4kgs

  • Recover the existing refrigerant charge in a suitable container. Local regulations may vary from region to region. Do not mix refrigerants.

  • Purge the circuit to -69 kpa (-10 psi)

  • Connect the gauges and hoses, then, with the compressor off, FILL the low-pressure side of the compressor with Duracool® 12a. Adjust the tip of the probe valve to establish the flow rate. (The flow stops if the tip is turned too much.) When a minimum load is reached, start the compressor and set the circuit to high pressure.

  • Add the necessary amount of Duracool® 12a

  • After checking the pressures and temperatures, remove the charging hose and place the Duracool® 12a label (included) on the refrigeration or air conditioning circuit. Make sure that the labels are clearly visible.

  • Remember that Duracool®12a is flammable and should only be leak-tested using an electronic hydrocarbon tester, soap bubbles or fluorescent screening fluid. If a leak occurs, ventilate the room, keep the product away from any open flames, and repair the leak. After repair, continue charging.

  • If the circuit has been overloaded or leaks and needs to be recharged, drain the entire circuit and start charging from scratch again.

  • If you need additional technical assistance, please call your local distributor Duracool® or DEEPCOOL

  • Your circuit will now operate at a much lower discharge pressure, its efficiency will increase significantly, and the customer will notice better cooling. PUT THE LABELS ON YOUR CIRCUIT.

    IMPORTANT NOTE: The equivalent weight of Duracool®12a to other refrigerants is specified in <<NET WEIGHT>>. ® Duracool 12a should be charged like a liquid.

  • DON'T OVERLOAD THE CIRCUIT! Exceeding 414 kpa (60 psi) on the low-pressure side may damage the compressor. In some cases, discharging the light can overload the circuit. Any overload can cause the loss of cooling efficiency

Additives

  • You don't have to use all the additives, each case is different. However, if you buy one or more different additives, please follow the instructions above.
  • Namely, each can of additive contains Duracool 12a, so the addition of one or more cans of additive can fill your gas circuit
