Wait at least five more minutes after confirmation that
there is no water flow to proceed with opening the sys-
tem for work. On higher temperature applications
(water temperature over 100°F but under 125°F) wait
at least 15 minutes. Do not shut off the freeze unit.

NOTE! Times are for Copper Tubing. Steel Pipe will take
slightly longer. Assumes water same temperature
as room temperature and use of both freeze heads
to form plug.
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 pos-
sibility of liquid coming out of the line and wear proper
protective gear 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 freeze unit while making repairs.
This will help insure that the plug does not melt while
the system is open.
7. Once the repair is complete and system is closed,
shut off and unplug Pipe Freeze unit, and allow ice
and frost to melt off the freeze heads and hoses.
Do not try to remove the freeze heads from
NOTICE
the pipe or coil the hoses until they are completely thawed.
This can result in damage to the hoses and freeze heads.

Ridge Tool Company
SuperFreeze™ Pipe Freezing Unit
If freeze heads and hoses must be removed more
quickly, a heat gun can be used to thaw them.
Cleaning and Storage
WARNING
Disconnect the plug before starting any kind of
maintenance work on the unit.
Do not open the refrigerant circuit. Refrigerant re-
lease can cause frostbite, asphyxiation and other
serious injury. In case of refrigerant release, leave
the area until the refrigerant dissipates. Do not in-
hale the refrigerant.
Cleaning
After each use, the freeze heads should be cleaned,
Wiped dry, and properly stored.
Machine Storage
1. Wipe frost/water from the fully thawed freeze heads
and lines. The Pipe Freeze Unit can now be stored by
coiling the hoses in the compartments adjacent to the
hose and adding the other equipment (Figure 8). Do
not cross the hoses to the compartment.
2. The aluminum freeze heads should be protected
from impact, sharp objects and rough handling.
