How do I install Mac Freeze

There are no new procedures or techniques to learn! The same equipment and gauges are used. The refrigeration system is charged in the same manner as with the refrigerant being replaced using the same pressure levels. Mac Freeze is completely compatible with synthetic or organic oils in all existing systems. No flushing or oil changes are required. The only difference is that Mac Freeze  is installed as a liquid.

1 - If system is charged, check system for leaks or defective components. Replace or repair as necessary. Determine that compressor has proper amount of lubricant according to manufacturer's specifications.

2 - Pull a vacuum according to manufacturer's specifications.

3 Connect gauges and hoses. With compressor off, open cylinder valve to install Mac Freeze on low pressure side of compressor (installing as a liquid will not harm the compressor). Establish flow rate. After a minimum charge is achieved, start compressor and set system to high.

Continue adding as needed to achieve proper pressure level according to manufacturer's specifications. DO NOT OVERCHARGE! Exceeding 50 psig on the low side may damage compressor. In some cases, clearing the site glass overcharges the unit. Any overcharge may cause loss of cooling efficiency.

4 - After verifying that the pressures and temperatures are correct, remove the charging hose and place the Mac Freeze stick on tag, which is, shipped along with each purchase, near the system's low pressure side access port.

If a system has been overcharged or has a leak and must be recharged, completely evacuate the system using reclaiming equipment (not recycling equipment) and start  the charging procedure over.
