Operating Instructions – Pipe Freezing Kit Model PFK-5-3, PFK-5-3 and PFK-DBL-5-3.

*Kit does not include Co2 bottle or cart however you can easily buy the Co2 bottles locally.

GENERAL:

The 2LBin.com pipe freezing kit uses liquid carbon dioxide to freeze stationary water in pipes. A very low "dry ice" temperature (-109ºF/-78ºC) inside the freezing jacket creates a secure ice plug within the pipe and blocks the flow of liquid, allowing repairs or modifications to be made to the piping system without draining or shutting down the entire system. Three freezing jackets, for 1/2" through 4" pipe, are supplied with the 2LBin.com Freezing Kit. The pipe freezing technique can be used on iron, lead, steel, copper, and plastic pipe. The 2LBin.com pipe freezing kit does not come with an empty CO2 cylinder. Check the local telephone directory or yellow pages for a source of CO2. Look under the headings "Gas-Bottled and Bulk" or "Welding Equipment and Supplies"

NOTE: The freeze kit will work only with a tank fitted with a siphon. A siphonless tank will not feed liquid CO2 -CO2 gas will not freeze pipes

GETTING READY:

1. Prepare the pipe to be frozen as follows:

a. Stop the flow of water through the pipe. Moving water will not freeze.
b. Water temperature should be at room temperature (75ºF/24ºC) or colder whenever possible. Warmer water takes much longer to freeze and hot water will not freeze.
c. Thoroughly clean the section of pipe to be frozen. Dirt and layers of paint will lengthen the freezing process.

2. Check all hoses, freezing jackets, threaded parts and nozzle for wear and replace any worn components. Make sure the nozzle is clean and clear.

FREEZING PIPES

Select the proper size freezing jacket based on the size of the pipe to be frozen.
Connect nozzle assembly to jacket, making sure that the nut inside of the brass grommet on the jacket is tightened securely to prevent leakage.
Connect the hose to the nozzle assembly and to the CO2 cylinder and tighten securely to prevent leakage.
While holding the jacket firmly to prevent the nozzle from whip lashing, briefly open the valve on the cylinder to make sure the nozzle is clear.
Determine the correct freeze location, taking into account the following points:

Always keep the freezing point 3 feet or more from a closed valve or connection.
Always keep the freezing point 3 feet or more from another freeze. NOTE: failure to observe this 36 inch margin of safety can result in damage to pipe due to the expansion of water as it freezes.
When torch cutting, welding, or soldering is to be performed on the pipe, keep the freeze at least one foot from work for each inch of pipe diameter when working on carbon steel or iron pipe. Triple the distance on copper pipe. Cutting, welding, or soldering too close to the freeze can damage the ice plug.

Wrap the freezing jacket around the pipe using the Velcro strips to seal the jacket in place and tie the cords tightly around the ends of the jacket. After this step, the use of protective gloves and safety glass provided in the kit is recommended to prevent frostbite.
Completely open the valve on the CO2 cylinder.
Squeeze the jacket while injecting CO2 to form a solid, even block of dry ice around the pipe. Crush any lumps that form in the ice using a rubber mallet.
The following chart applies to freezing completely stationary, 70ºF water in carbon steel pipe. Adjust times according to actual conditions, allowing more time for warmer water or slight flow of water.
Multiply all times by 3 for plastic pipe.

Keep extra filled CO2 cylinders on hand. Have at least 2 full cylinders available when freezing 2-inch pipe, and 3-4 full cylinders for 3 to 4 inch pipe. All cylinders must be equipped with a siphon and must be kept upright when in use. For double freeze jobs keep double the amount of CO2 cylinders.
: A full 20 pound CO2 cylinder contains about 18 pounds of usable CO2 and weighs 45 Pounds. An empty cylinder weighs 27 pounds. Weigh the cylinder between freezes to determine its approximate content.

As a safety precaution, make additional 30-second injections every 15 minutes.

When work is completed, remove the freezing jacket from the pipe and allow the freeze to thaw naturally. Do not attempt to thaw the freeze with a torch as thermal shock damage to the pipe can occur. Always wear protective gloves and safety glass provided when handling jacket, dry ice pack, or frozen pipe.

IMPORTANT INFORMATION ON CO2 AND CO2 CYLINDERS

All CO2 cylinders need to be equipped with a siphon to drain liquid CO2 from the bottom of the cylinder. CO2 gas will not form dry ice.
All CO2 cylinder valves need to be fitted with a safety-bursting disc to protect against over pressurization. If the cylinder is overfilled or subjected to temperatures over 100ºF, the bursting disc may rupture, allowing violent discharge of CO2 gas.
Always weigh tanks to prevent overfilling.
Store all CO2 cylinders out of sunlight and away from heat.
Never transport cylinders in the driver's compartment of a vehicle, as a sudden rupture of the bursting disc could distract the driver.
The 2lbin.com pipe freezing kit works best when the cylinder temperature is kept below 77ºF. It will not work if the cylinder temperature reaches 88ºF.

CAUTION: CO2 is heavier than air and will collect in confined or low-lying work areas. Always make sure there is good ventilation to prevent suffocation. CO2 gas is odorless and invisible. Disperse CO2 before entering a confined or low-lying work area.
