WARNING! Read these instructions and
the accompanying safety booklet carefully
before using this equipment. If you are un-
certain about any aspect of using this tool, contact
your RIDGID distributor for more information.
Failure to understand and follow all instructions
may result in electric shock, fire, and/or serious
personal injury.
SAVE THESE INSTRUCTIONS!
Specifications:
The Super Freeze is designed for use as a pipe-freezing tool. We strongly
recommend that it NOT be modified and/or used for any other application.
Physical characteristics, capacity and standard equipment: see fig 1.1
(SF 2500) and 1.2 (SF 2200).
Transport and handling:
Avoid shocks or violent movements. Secure the unit firmly during transport.
Inspect the unit for signs of damage and fully uncoil hoses before connecting
line cord to power supply.
Safety:
Caution: The freezing heads become very cold. Wear gloves to avoid risk of
frostbite.
Ground machine. Always plug the cord into a properly grounded socket.
Set up, positioning and operation:
• Stop water flow otherwise unit will not freeze ice plug.
• If possible allow the system to cool before freezing.
Warm water will cause circulation increasing the freeze time.
• Clean pipe and remove paint and insulating material.
• Connect freezing heads at same point for single ice plug or a suitable
distance for two separate plugs (Fig 2.1 and 2.2) using the cavity that
best fits the outside diameter of pipe.
Do not twist or kink hoses
• Switch on unit after ensuring there is unrestricted air circulation for the
fan.
After 2-3 minutes the heads will be at operating temperature.
SF 2200: Cool gel (cat.nr. 74946) must be applied:
1. Between the cylinder freezing head and the adapter.
2. Between the pipe and the adapter.
Cool gel will help speed up the process. (Fig. 3.2) Allows better contact for
faster freezing process.

Operating Instructions
SF 2500: Water must be sprayed between the pipe and the head using
the spray bottle to give better contact (Fig 3.1) and will speed the freezing
process.
• Allow sufficient time for the ice plug to form (see table for approximate
freezing times) indicated by a sharp cracking sound from the pipe.
• Test the pipe for pressure by opening a valve or fitting downstream by
installing a line tap. The pipe can now be serviced.
• The Super Freeze should be kept running during the service period.
• When the work is completed, switch off unit and remove line cord from
socket.
Do not force the heads from the pipe to avoid damaging them.
• Let hoses defrost before storing in case.
• Wipe any moisture from the heads and the hoses before storing in the
case.
To obtain the best freezing times:
• Check for good contact between head and pipe.
• Add Cool gel between adapter and pipe — head and adapter.
• Check if hose orientation is perpendicular towards pipe and the freeze
head is in one line with the hoses. (Fig 4.1 and Fig. 4.2) This is vital for
obtaining optimal freeze times.
• Connect freezing head to the top of a horizontal pipe section
• Wrap insulation around head and pipe.
Note: Approximate freezing times shown in tables give an approximate guide
for system temperatures between 15°C and 25°C.
Faster freeze times will be obtained with Copper tubes.
Any paint or dirt on the tube will increase the freeze time.
Troubleshooting:
• If heads do not become frosted:
Check power, check free air flow for fan and clean if required. Switch off
power and wait 3-5 minutes before restarting.
• If heads get cold but will not freeze:
Check for water flow in pipe.
• If unit stops: Wait 30 seconds before restarting.
Note: The compressor is thermally protected and will reset automatically after
an overload. If unit still does not function correctly and for all other maintenance
contact your RIDGID distributor.
