Capacities For Copper Tube &Steel Pipe - RIDGID SuperFreeze SF-2300 Operator's Manual

SuperFreezer
• Determine if the piping is filled with water. A plug
cannot be frozen into partly filled pipes.
• Determine where the piping system needs to bro-
ken for the work that needs to be done.
• Locate piping system shut-off valves or determine
other methods to shut off system fluid flow to be
used in case of emergency.
3. Determine location for freeze plug(s).
• The location must allow access for at least one
freeze head. If only a single plug is required, it is
preferred that there be enough space for both
freeze heads. Freeze heads should not contact
more than one pipe.
• If the system will be soldered, brazed, welded, or
other heat adding processes performed, the freeze
plug(s) must be located as far away from the repair
as possible. Excess heat can prematurely thaw the
ice plug and allow water to flow while the system is
open. The freeze plugs should be a minimum of one
foot (0.3 m) away from the heat for each inch (25
mm) of diameter for steel pipe or tube. For all other
materials, the plug should be at least three feet
(0.9 m) away for each inch of pipe or tube diameter.
• Ice plugs must be more than one foot (0.3 m) away
from end caps, elbows, closed valves, other ice
plugs or similar obstructions. Placing an ice plug
closer can cause splitting of the pipe or tube.
• Do not place ice plugs closer than 5 feet (1.5 m)
from a circulating hot water (water hotter than
ambient air but cooler than 100°F (38°C)) main for
pipe sizes 1" (25 mm) and smaller or closer than 8
feet (2.4 m) from a circulating hot water main 1
(30 mm) or larger. Plugs placed closer to a circu-

lating hot water main can prevent plug formation
or can cause plug thawing.
4. Prepare the freeze plug locations. Remove all insula-
tion and coatings from the pipe down to bare metal. If
needed, remove any corrosion with a wire brush.
Coatings and corrosion insulate the pipe and can
slow or prevent the freezing process.
5. Place the unit so that freeze heads can reach desired
plug points. Locate SuperFreeze on a solid, level sur-
face, in an upright position. If the unit is not upright and
level, it can cause damage to the compressor. Make
sure the air inlet/outlet to condenser are not blocked.
Blocked condenser openings will slow or prevent the
freezing process. Be sure to locate the pipe freezing
unit away from where the repair will occur and not
under the freeze heads. This will help prevent the
entry of water into the freezing unit and help prevent
electrical shock.
6. Uncoil the hoses to the freeze heads. Use care not to
twist or kink the hoses, this can damage the hose
and prevent proper operation.
7. Choose the appropriate freeze head cavity for the
size of pipe or tube to be frozen. The capacities for
copper tube and steel pipe are listed in the chart that
follows. Adapter bushings are required in some appli-
cations. If using on pipe or tube other than listed
sizes, the pipe/tube diameter cannot be smaller than
the freeze head/bushing diameter -1/8" (3.2 mm).
8. Apply freeze gel to the freeze head cavity. If using end
adapter or bushings, apply freeze gel between the
freeze head and the adapter and to the adapter sur-
face that contacts the pipe. The freeze gel improves
