The SuperFreeze Pipe Freezer is an easy-to-use pipe-freezing
unit that allows the contractor to keep water systems operating
while making repairs. The RIDGID® Model SF-2500 is a mini-
refrigeration unit that circulates self-contained refrigerant to its
aluminum freeze heads. This forms an ice plug in as little as 6
minutes. Once the pipe is plugged, repairs can be made while
the ice plug is maintained by the unit. Includes a bottle of
specially formulated freeze gel to speed freezing. Apply the gel
to freeze heads before placing on pipe.

General Safety Rules
WARNING
Read all safety warnings and all instructions. Failure
to follow the warnings and instructions may result
in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE!
Work Area Safety
•Keep your work area clean and well lit. Cluttered or
dark areas invite accidents.
•Do not operate tools in explosive atmospheres,
such as in the presence of flammable liquids,
gases, or dust. Tools create sparks which may ignite
the dust or fumes.
•Keep children and by-standers away while operat-
ing a tool. Distractions can cause you to lose control.
Electrical Safety
•Grounded tools must be plugged into an outlet
properly installed and grounded in accordance
with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do
not use any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the out-
let is properly grounded. If the tool should electrical-
ly malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
•Avoid body contact with grounded surfaces such
as pipes, radiators, ranges and refrigerators. There
is an increased risk of electrical shock if your body is
grounded.
•Do not expose the equipment to rain or wet con-
ditions. Water entering a tool will increase the risk of
electrical shock.
•Do not abuse the cord. Never use the cord for car-
rying, pulling or unplugging the tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged or
entangled cords increase the risk of electric shock.
•When operating a tool outside, use an outdoor
extension cord marked “W-A” or “W”. These cords
are rated for outdoor use and reduce the risk of elec-
tric shock.
Personal Safety
•Stay alert, watch what you are doing and use com-
mon sense when operating a tool. Do not use a
tool while you are tired or under the influence of
drugs, alcohol, or medication. A moment of inat-
tention while operating tools may result in serious
personal injury.
•Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.

Description, Specifications and
Standard Equipment
Description
The RIDGID®SuperFreeze®Pipe Freezing Units are used
to freeze plugs in water piping systems to allow mainte-
nance without shutting down or draining the system. The
units are self-contained refrigeration units that circulate
refrigerant to the aluminum freeze heads. The freeze
heads, attached to the piping system, can freeze a plug in
metallic tubing or pipes. Once the work is complete, the
SuperFreeze unit is turned OFF and the ice plugs melt,
returning the system to operation.
The SuperFreeze units do not use CO2or Nitrogen, and do
not require the release of refrigerants. They use specially
designed compressors with overload protection. The SF-
2500 also includes quick restart capabilities. The freeze
head hoses are leak free flexible rubber. The units are
enclosed in a portable carry case.

Machine and Work Area Set-Up
WARNING
Set up the pipe freezing units and work area accord-
ing to these procedures to reduce the risk of burns,
electrical shock and other injuries and prevent
machine damage.
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite. If
present, do not work in area until sources have
been identified and corrected. The Pipe Freezing
Units are not explosion proof and can cause sparks.
• Clear, level, stable, dry location for all equipment
and operator.
• Properly grounded electrical outlet of the correct
voltage. A three-prong or GFCI outlet may not be
properly grounded. If in doubt, have outlet inspect-
ed by a licensed electrician.
• Clear path to electrical outlet that does not contain
any potential sources of damage for the power cord.
• Clear path for access to the work area.
2. Inspect the system and determine if the Pipe Freezing
Unit will work.
• Determine the system fluid – the unit will only work on
systems containing water. Know what additives are
in the water. Additives can change liquid freeze tem-
perature and make freezing difficult or impossible.
• Determine the system material and size – the unit
will only work on metallic piping systems. For pipe
and tube material and size see Specifications .
• Determine the system water temperature and air
temperature in the area of the desired plug. If
temperatures exceed
up to 1" (25 mm) sizes – 110°F (43°C)
11/4" (32 mm) and 11/2" (42 mm) sizes – 90°F (32°C)
2" (54 mm) and larger sizes – 80°F (27°C)
The water/air must be cooled to below these tem-
peratures for the SuperFreeze unit to be used.
• Determine if there is flow in the system – the pipe
freezing unit will not work on flowing water. If there
is flow in the section of pipe to be frozen, the flow
needs to be stopped by shutting a valve, turning
OFF a circulating pump, or other appropriate means.

This product is used to freeze ice plugs in
water piping systems. The ability to freeze plugs is
dependant on a wide variety of factors as discussed in
this manual. Depending upon the exact set of circum-
stances, this product may not work in all cases.
Pre-Operation Inspection
WARNING
Before each use, inspect your pipe freezing unit
and correct any problems to reduce the risk of seri-
ous injury from electrical shock and other causes
and prevent unit damage.
1. Make sure that the pipe freezing unit is unplugged and
the ON/OFF switch is in the OFF position.
2. Clean any oil, grease or dirt from all equipment and
controls. This aids inspection and control of the unit.
3. Inspect the pipe freezing units for the following:
• Inspect the cord and plug for damage or modifi-
cation.
• Proper assembly, maintenance and completeness.
• Any broken, worn, missing, misaligned or binding
parts.
• Presence and readability of the warning label.
(See Figures 1 and 2.)
• Any other condition, which may prevent safe and
normal operation.
If any problems are found, do not use the pipe freez-
ing unit until the problems have been repaired.
4. Check the hoses to the freeze heads for cracks, kinks,
breaks or other issues. The hoses can be coiled and
flexed when not frosted. Care must be taken not to
twist or kink hoses. This prevents hose damage.
5. Inspect the fan grille and louvers into the condenser
housing to make sure that nothing is blocking the air-
flow. Lack of airflow through the unit can cause per-
formance issues or damage the unit.
6. With dry hands, plug cord into properly grounded out-
let, Move the switch to ON position. Confirm that the
compressor motor starts and that the fan runs. Move
the switch to OFF position and unplug the unit.

• 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 11/4"
(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

Forming a single freeze plug with freeze heads
positioned opposite to each other and using freeze
gel and quick grip clamp is the preferred method
for use on more difficult applications (higher tem-
peratures, larger pipe sizes, etc.). If two freeze
plugs are required in a difficult application, it may
be necessary to use two pipe freezing units, one
for each plug.
• Two freeze plug applications – When two separate
freeze plugs are required to isolate a section of the
system, one freeze head is attached at each point
(Figure 6) . Tightly secure the freeze heads to the
pipe with either Quick Grip clamp or Velcro straps.
If using the Quick Grip clamp do not over tighten
the clamp and deform the pipe.
Figure 6 – Two Freeze Plug Application
• If the standard freeze head cannot be used, adap-
ters are available. Freeze gel (if being used) is
applied to the back of the adapter and to the sur-
face that contacts the tube. Tightly secure the
freeze heads to the tube with either the Quick
Grip clamp or the Velcro straps. If using the Quick
Grip clamp do not over tighten the clamp and
deform the tube.
See Figure 7.

the thermal conductivity between the freeze head
and the pipe and decreases the time required to
freeze a plug. If no freeze gel is available, use the
spray bottle to spray water generously before and
during the pipe freezing process.

Clamp
Figure 5 – Applying Freeze Head with Velcro Strap
9. Attach the freeze heads to the pipe.
• Single freeze plug applications – In single freeze
plug applications, both freeze heads should be
applied opposite each other to form the plug. This
will decrease the time required to freeze the plug.
Use the Quick Grip clamp (Figure 4) or Velcro
Strap
(Figure 5) to secure the freeze heads to the
pipe. If using the Quick Grip clamp do not over
tighten the clamp and deform the pipe.

dry hands, plug the SuperFreeze into the previously
identified properly grounded outlet. If the power cord
is not long enough, use an extension cord that
• Is in good condition.
• Has a three prong plug similar to that supplied
on the Pipe Freezing Unit.
• Is rated for outdoor use and contains a W or W-A
in the cord designation (i.e. SOW), or complies with
H05VV-F, H05RN-F types or IEC type design
(60227 IEC 53, 60245 IEC 57).
• Has sufficient wire size (16 AWG (1.5 mm2) for 50'
(15.2 m) or less, 14 AWG (2.5 mm2) for 50' – 100'
(15.2 m – 30.5 m) long). Undersized wires can
overheat, melting the insulation or causing a fire or
other damage.
Operating Instructions
WARNING
Before opening system, test to confirm that the ice
plugs are fully formed and stable. Opening the piping
system before a complete plug is frozen or allowing
the plug to thaw while the system is open could
cause burns, electric shock or other serious injury or
result in flooding or other property damage. Make
sure the machine is properly set up and do not allow
the Pipe Freezing Unit to shut OFF during use.
The freeze heads and hoses get extremely cold
and can cause frostbite if touched during operation.
Wear gloves if handling during use.
Always wear eye protection to protect your eyes
from dirt and other foreign objects. Always wear
appropriate protective equipment for the piping
contents.
Follow operating instructions to reduce the risk of
injury from burns, frostbite, electrical shock and
other causes.
1. Make sure that machine and work area is properly set
up and that the work area is free of bystanders and
other distractions.
2. Turn the machine ON.
3. Allow the machine to run for 2-3 minutes. Freeze
heads should start to frost. Use spray bottle to spray
water between freeze heads and pipe. The water
will freeze and fill any gaps between the freeze head,
pipe and any adapters used. This improves thermal
conductivity and will improve freeze times, while gaps
between the freeze head and pipe will prevent freeze
plug formation. Make sure that any dripping water
does not cause a hazard. If freeze gel was used,
then water spray may not be necessary.
If the freeze heads do not become cold and cov-
ered with ice and frost after approximately 7 min-
utes, turn the unit OFF for 3 minutes and restart. If the
freeze heads still do not become cold, see the
“Troubleshooting” section.
4. Once the freeze heads are frozen to the pipe, allow
the ice plug to form. If the ambient temperature is
high, but not above 100°F (38°C), the freeze heads
can be wrapped with pipe insulation or other insulation
to improve freeze times.

9
SuperFreeze®Pipe Freezing Units
Do not leave the unit unattended. Pipes can freeze
and split during the freezing process and monitoring
can minimize the hazard and damage. If for some rea-
son the power to the freezing unit is interrupted, turn
the ON/OFF switch to OFF and do not restart for at
least 30 seconds to prevent compressor damage.
Figure 9 – Freeze Head Frozen to Pipe
Time to freeze a fully formed ice plug depends on a
variety of factors, including water temperature, ambi-
ent temperature, distance from heat sources, pipe size
and wall thickness, pipe material, number of freeze
heads, quality of contact between freeze heads and
pipe, and other conditions. The following table of
freeze times is based on water temperature being the
same as ambient temperature, use on copper tube,
use of freeze gel and use of two freeze heads. Freeze
times for steel pipe will be longer. Freeze times for
other less optimal conditions may be double those
shown or greater. Freeze times are only provided
as a general guide.
5. Carefully test the system to make sure that the plugs
are complete and there is no flow before opening
the system. This can be done by opening a valve
downstream of the plug and verifying that there is no
flow. Another method is to use a saddle tap valve
(similar to those used to install icemakers) to pierce a
copper tube and check for water flow. If there is flow,
close the system and continue the freezing process.
Wait at least five more minutes after confirmation that
there is no water flow to proceed with opening the
system for work. On high temperature applications,
water temperature over 90°F (32°C) but below 100°F
(38°C), wait at least 15 minutes. Do not shut OFF the
freezing unit.
6. Once the ice plug has been completely formed and
enough time has passed since confirmation that there
is no flow in the pipe, the pipe can be opened. When
opening the system, be prepared for the possibility of
liquid coming out of the line and wear proper protec-
tive equipment in case a plug fails. Be sure to follow
the guidelines in the set up section for distance from
plug to heating of system for soldering, brazing, etc.
Do not shut OFF the freezing unit while making
repairs. This will help insure that the plug does not
melt while the system is open.
7. When the repair is complete and system is closed,
shut OFF and unplug pipe freezing unit, and allow ice
and frost to melt off the freeze heads and hoses.
Do not try to remove the freeze heads from
the pipe or coil the hoses until they are completely
thawed. This can result in damage to the hoses and
freeze heads. If freeze heads and hoses must be
removed more quickly, a heat gun can be used to thaw
them.
Cleaning
After each use, clean the freeze heads with a soft cloth.
Clean the condenser fan grilles to remove dirt. Wipe
frost/water from the fully thawed freeze heads and hoses.

PROBLEM POSSIBLE REASONS SOLUTION
Freeze heads do not be-
come frost-covered after
7 minutes.
The freeze heads get
cold and frost covered
but the pipe will not
freeze.
Tripping of the unit.
Troubleshooting
Unit has been stored in a cold location; unit has
not been used for long time.
No power supply.
No air circulation to the condenser unit.
Pipe Freezing unit has lost its charge.
Water flow in the pipe.
Poor contact between heads and pipe.
Pipe is not completely full of water.
System is filled with something other than water.
Water temperature is too high.
Air temperature is too high.
Overloading of the compressor.
If freeze heads are not cold and frost-covered
after 7 minutes, turn the unit OFF. Keep the unit
OFF for 3 minutes, and then restart.
Make sure of proper power supply without any in-
terruption & compressor fan running.
Check that there is unrestricted air circulation to
the condenser unit. Check the condenser unit’s
inlet air ports and clean.
Contact Technical Service Department at Ridge
Tool (see Service and Repair) .
Check for water flow. If this exists, stop the flow.
Use the water spray bottle or freeze gel to build
an ice bridge and provide the contact for heat
transfer. The slightest air gap will prevent freezing
Make sure system is full of water.
Pipe freezing unit will not work.
Allow the system to cool off or freeze heads are
too close to circulating main, stop flow in circulat-
ing main.
After freeze head is frozen to pipe, wrap with insu-
lation.

time for automatic restart.
