Operating instructions
For your own safety, before using this equipment,
read these instructions and the accompanying
safety booklet carefully and completely.
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.
• 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: Freeze gel must be applied:
Freeze gel will even more speed up the process. (Fig. 3.2) Allows better
contact for faster freezing process.
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 freezing 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: 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 re-starting.
• 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.
Important
Keep these instructions.
Do not twist or kink hoses
1. Between the cylinder freezing head and the adapter.
2. Between the pipe and the adapter.
