How to Use HC-12a - HC12AUSA.com

HC-12a® Charging Instructions

1. Existing refrigerant may need to be reclaimed by qualified personnel. The weight of the recovered refrigerant should be recorded. Local regulations may vary by region and the technician should be aware of all applicable requirements.

2. Pull a system vacuum and leak test.

3. Using the weight of the recovered refrigerant, or the system label information, the weight of HC-12a® required will be approximately 35% of the weight of the recovered CFC, or approximately 40% of the weight of the ecovered HFC refrigerant.

4. Connect gauges and hoses, then with the compressor off, install HC-12a® on the low-pressure side of the compressor. After a minimum charge is achieved, start the compressor and set system to high.

5. Add additional HC-12a® as needed. Do not overcharge the system.

6. After verifying that pressures and temperatures are correct, remove the charging hose and place the HC-12a® label (supplied) on the air conditioning system. Ensure all labels are visible and clearly displayed.

7. If additional technical assistance is needed, please call your nearest hydrocarbon refrigerant distributor or Northcutt, Inc. directly.

8. The air conditioning system will now operate at cooler inside temperatures and a much lower head pressure, improving energy efficiency.

IMPORTANT: The equivalent weight of HC 12a® to alternative refrigerants is shown in "NET WT." HC 12a® is designed to be charged as a liquid.

DO NOT OVERCHARGE. Exceeding 60 psig (414 kPa) on low side may damage compressor. In some cases, clearing the site glass overcharges the unit. Also, overcharging may cause loss of cooling efficiency.

HC-22a®, HC-502a® Charging Instructions

1. Operate the system for 24 hours and record temperature and pressures of unit operation. Inspect the system, make any required repairs and perform routine maintenance before charging with hydrocarbon refrigerant.

2. Existing refrigerants may need to be removed and reclaimed by qualified personnel. The weight of the recovered refrigerant should be recorded. Local regulations may vary by region and the technician should be aware of all applicable requirements.

3. Perform a system vacuum and confirm that system does not leak.

4. Connect liquid valve from cylinder to gauge manifold Make sure the charging lines are clean and purged.

5. Connect manifold equipment to the low-pressure side of system. Ensure all components have been properly grounded. When charging a large system, the charging equipment, hoses and system must be grounded to stop a buildup of static electricity.

6. When all connections have been made, insure there are no leaks before continuing.

7. Partially closing the suction service valve will reduce the flow from the regular evaporators and speed the transfer of refrigerant from the charging cylinder to the system.

8. Using the weight of the recovered refrigerant, or the system specifications, the weight of HC-22a® or HC-502a® required will be approximately 40% of the weight of the recovered HCFC or CFC refrigerant.

9. After verifying that pressures and temperatures are correct, remove the charging equipment and attach the HC System label (provided) to the system in a prominent area.

Cylinders must be returned undamaged and in a vacuum state with all valves closed and caps in place to be eligible for credit.

EQUIVALENCY INFORMATION

HC Refrigerant products are efficient. HC-12a® needs only a 35% charge, by weight, of CFC R12, and a 40% charge, by weight, of HFC R134a. HC-22a® and HC-502a® require only a 40% charge by weight of HCFC R22 and CFC R502. The following table converts our product containers to the respective weights of the refrigerants they replace:

HC-12a®
6oz can = 17oz of CFC R12 and 15oz of HFC R134a
30 lb cylinder contains 12 lb of HC-12a® = 34 lbs CFC R12 and 30 lbs HFC R134a
50 lb cylinder contains 20 lb of HC-12a® = 57 lbs CFC R12 and 50 lbs HFC R134a
HC-22a®
50 lb cylinder contains 20 lb of HC-22a® = 50 lbs HCFC R22
HC-502a®
50 lb cylinder contains 20 lb of HC-22a® = 50 lbs of CFC R502

NOTE: HC Refrigerants are flammable and should be leak tested using an electronic hydrocarbon leak tester, fluorescent tracer fluid, or soap bubbles. If leaks are discovered during charging, maintain adequate ventilation, keep open flames away, and repair the leak. After repairs have been made, resume the charging procedure.
